Polyurethane Foam
PORON® Dura-Shape
Overview
PORON® Dura-Shape® is a specialized option that integrates a durable polyester film between two layers of PORON® polyurethane foam. This “sandwich” construction enhances dimensional stability without affecting the material’s compressibility—making it an excellent choice for precise die-cut gaskets and seals that demand long-term shape retention.
Features
- Increased dimensional stability — resists stretching or shrinkage over time.
- Tougher tear strength — improves durability during processing and use.
- Maintains compressibility — retains the sealing and cushioning performance of standard PORON® foams.
- Wide temperature performance — performs reliably across diverse environmental conditions.
- Chemical resistance — sustains functionality in contact with common industrial fluids and environments.
Benefits
- Long-term shape retention — gaskets and parts maintain precise dimensions over time.
- Faster, more accurate die-cutting — supports streamlined fabrication and higher yield.
- Enhanced mechanical reliability — improves product lifespan in high-performance applications.
- Reliable sealing and cushioning — preserves PORON® material characteristics with added structure.
Applications
- Precision gasketing and sealing where dimensional stability is critical.
- High-volume die-cut manufacturing—especially for handheld devices and industrial components.
- Shock absorption and cushioning in environments with repeated compression demands.
- Applications where material must hold tight tolerances under mechanical and thermal stress.
Why Choose PORON® Dura-Shape®?
- Offers the proven sealing and compression benefits of PORON®, enhanced with rigid shape stability.
- Ideal for high-speed, high-accuracy die cutting and long-term gaskets.
- Greatly reduces material deformation—elevating reliability in finished parts.
- Extends PORON® performance to demanding, shape-critical applications across industries.
