Biopolymer Applications and the Industries We Serve

Explore how Phast works with manufacturers to develop application-ready PHA materials for dental, medical, personal care, infant care and other products where performance, manufacturability and end of life all matter.

Not every product is designed to last forever. Why should its material be?

From dental trays used for weeks to medical and personal care products used once, temporary products create an opportunity to rethink what they’re made from.
 
Yet many are still made from conventional plastics designed to persist long after the product has served its purpose.
 
At Phast, we see an opportunity to rethink that equation. We work with manufacturers to explore where polyhydroxyalkanoates (PHAs) can deliver the performance a product requires during its useful life while creating a different outcome at end of life.

One Material Family. Engineered Around Your Application.

You don’t adapt your product to the material. We work to adapt the material to your application.

That can mean evaluating properties such as:

  • Flexibility and rigidity
  • Clarity and appearance
  • Strength and durability
  • Skin or oral contact requirements
  • Processing and forming behavior
  • Product lifespan
  • End-of-life objectives

The goal isn’t to replace plastic everywhere. It’s to identify where PHA makes sense, and engineer it to perform where it matters.

PHA Applications by Industry

Different products demand different things from their materials. That’s why we don’t approach PHA as a one-size-fits-all replacement for conventional plastic. We develop materials around the application, considering how the product is made, how it needs to perform, how long it needs to last and what happens when its job is done.

Industrial Applications

A proving ground for next-generation materials.

Dental products demand precision from both the product and the material. Whether it’s an aligner, whitening tray, impression tray, retainer, or packaging component, manufacturers rely on materials that form consistently, perform reliably, and deliver a positive patient experience.

Applications We’re Exploring

  • Impression trays and strips – engineered for the adhesive, clear, flexible film these products require
  • Whitening trays
  • Retainers and orthodontic aligners — built for extended in-mouth wear
  • Sports mouth guards and night guards — repeated daily use with direct oral contact
  • Orthodontic accessories
  • Dental packaging

Whether a product requires clarity, flexibility, durability or precise thermoforming, we work with manufacturers to evaluate and develop PHA materials around the application’s requirements.

Where engineering, performance, and innovation come together.

Medical products demand careful attention to quality, performance, manufacturing, and regulatory expectations. For select temporary-use products, manufacturers are evaluating whether PHA can become part of the next generation of medical materials.

Applications We’re Exploring

  • Diagnostic disposables — including flexible, biocompatible components for sample collection
  • Procedure accessories — such as breathable, non-adherent wound contact films
  • Ostomy and skin-contact accessories — where skin-safe, flexible, adhesive-compatible materials matter most
  • Scar and post-procedure treatment sheets — soft, skin-safe films with moisture-barrier performance
  • Respiratory therapy accessories — soft, skin-safe components for prolonged nightly use
  • Implantable devices – such as stents, fixation plates, surgical sutures and internal meshes, where a safe in vivo degradation is crucial for patients
  • Medical packaging

Our team works alongside engineers and product developers to determine where PHA aligns with the application’s technical, manufacturing and regulatory requirements.

Where parental trust meets material science. Few purchase decisions come under more scrutiny than the products placed in a child’s hands or mouth. Parents are increasingly reading ingredient and material labels on baby products the same way they read them on baby food, and manufacturers are responding by looking closely at what these products are made from.

Applications We’re Exploring

  • Teething rings and teething mitts — chew-safe materials for a product used constantly during a specific developmental window
  • Feeding spoons and training utensils — food-safe, soft-edged components for daily oral contact
  • Pacifier shields — materials evaluated for safe, sustained oral contact
  • Bath toys, grippable blocks, and sensory toys — water-resistant, chew-safe, ergonomic designs
  • Baby finger toothbrush sleeves — soft, safe materials for early oral care routines

PHA gives manufacturers another material platform to evaluate for products where safety, performance and sustainability all influence the design decision.

Sustainable products begin with thoughtful material choices.

Consumers increasingly notice more than packaging. They’re paying attention to the products themselves. Manufacturers are responding by exploring materials that align with evolving customer expectations while maintaining product quality and manufacturing efficiency.

Applications We’re Exploring

  • Cosmetic applicators and beauty tools
  • Biodegradable facial sheet masks and facial wipes — skin-safe, compostable nonwoven materials
  • Exfoliating beads — a direct, biodegradable alternative as microbead regulations tighten
  • Menstrual cups — soft, biocompatible materials for extended internal use
  • Personal care accessories such as earplugs and foot insoles — custom-molded, comfort-driven products
  • Sample products and promotional items

We help manufacturers evaluate where PHA can support comfort, performance, manufacturability and sustainability without losing sight of the consumer experience.

A different approach to temporary components and consumables.

Industrial products often operate in demanding environments where reliability and consistency are essential. While not every industrial product is suited for PHA, many temporary products and consumable components deserve a closer look.

Applications We’re Exploring

  • Protective caps
  • Temporary covers
  • Shipping protection
  • Consumable molded parts
  • Installation accessories

We’re helping manufacturers evaluate where product lifespan, manufacturing requirements, and environmental goals align.

Emerging Applications

Innovation starts with curiosity.

 
Innovation rarely starts with all the answers. More often, it starts with someone asking, Could this work? We’ve had that conversation with product developers, engineers, researchers, and manufacturers exploring higher-complexity applications — from absorbable sutures and biodegradable surgical mesh to wearable electrodes, smart patches, and implantable drug delivery systems. These applications carry greater regulatory complexity and longer development timelines, and that’s exactly what makes them worth exploring early and carefully.
 
If you’re working on an application that doesn’t fit neatly into one of the industries above, we want to hear about it.

Could PHA Work for Your Product?

The best opportunities for PHA often begin with a simple question: What does this product actually need from its material? Rather than starting with a predetermined solution, we look at the application as a whole.

We ask:

  • What does the product need to do?
  • How is it manufactured today?
  • What performance requirements must it meet?
  • How long is it intended to be used?
  • What regulatory or end-use requirements apply?
  • What happens after the product has served its purpose?

If your product… Is part of a broader sustainability initiative
PHA may be worth exploring because… PHA offers manufacturers another option for reducing the long-term environmental impact of temporary products.

Why Manufacturers Are Evaluating PHA

Material selection has always been about balancing performance, manufacturability, cost, and quality. Today, manufacturers are adding another consideration: what happens after a product has done its job. PHA gives engineering and product development teams another material to evaluate when both performance and sustainability are part of the design criteria.

PHA Characteristic Why It Matters
Biobased thermoplastic Produced from renewable resources rather than fossil-based feedstocks.
Compatible with conventional manufacturing Can be evaluated using familiar processes including injection molding and thermoforming.
Reliable performance Designed to provide the consistency manufacturers expect throughout the product's intended life.
Design flexibility Supports evaluation across a wide range of temporary products and applications.
Biodegradable under appropriate conditions Designed to biodegrade under the appropriate environmental conditions rather than persist indefinitely like conventional plastics.
Collaborative material development Allows engineering teams to evaluate new possibilities without abandoning proven product development practices.

Every application is different. Material selection depends on performance requirements, manufacturing methods, regulatory considerations, and end-use conditions. Our team works alongside manufacturers to determine whether PHA is the right fit.

FAQs About Whether PHA Is Right for Your Application

How do I know if my product is a good candidate for PHA?

The best candidates are often products designed for temporary use that still require dependable performance and consistent manufacturing. Every application is evaluated individually, which is why we begin by understanding your product before recommending a material.

We already have a product in production. Can Phast still help?

Yes. Many of our conversations begin with manufacturers who already have a successful product and want to evaluate whether PHA could support future product improvements or sustainability goals. We work with your team to understand your existing design and manufacturing process before recommending a path forward.

Do we need to redesign our product or manufacturing process?

Not necessarily. PHA can be evaluated using familiar manufacturing processes such as injection molding and thermoforming. Depending on the application, adjustments may or may not be needed. We’ll help you evaluate what’s practical for your product.

When should we involve Phast?

The earlier, the better. Bringing our team into the conversation during product development gives everyone more flexibility to evaluate materials before important design decisions are finalized. That said, we’re equally happy to support existing products that are ready for a fresh look.

What makes working with Phast different?

We don’t simply supply material—we collaborate with engineering and product development teams to solve material challenges. Sometimes PHA is the right solution. Sometimes it isn’t. Our goal is to help you make the best material decision for your application.

I'm exploring an application that isn't listed here. Should I still reach out?

Absolutely. Many of the most exciting projects we work on don’t fit neatly into a single industry. If you’re asking, ‘Could PHA work for this?’, we’d welcome the opportunity to explore it with you.

Better materials start with better questions.

What does your product need to do? How long does it need to do it? And what should happen when it’s done? Whether you’re developing a new product, rethinking an existing one, or exploring what’s possible, Phast can help you determine whether PHA belongs in the conversation.
