Sealing Strip Materials Explained: PVC, TPE, PU Foam

Understanding Different Materials for Sealing Strips

PVC (Polyvinyl Chloride)

PVC is a widely used thermoplastic material known for its durability and cost-effectiveness. It is resistant to moisture and various chemicals, making it suitable for outdoor applications.

TPE (Thermoplastic Elastomer)

TPE combines the characteristics of rubber and plastic, offering flexibility and resilience. It provides excellent sealing capabilities with a soft-touch feel, ideal for consumer products.

PU Foam (Polyurethane Foam)

PU Foam is known for its excellent thermal insulation properties and compressibility, which enhances its sealing benefits. Its significant flexibility makes it a popular choice in various industries.
