What is EPDM Rubber?

EPDM (Ethylene Propylene Diene Monomer) is a high-performance synthetic rubber known for its exceptional resistance to weathering, ozone, UV radiation, and temperatures. Its durability and flexibility make it an ideal material for sealing profiles in demanding environments.

Benefits of EPDM sealing profiles

Weather & UV resistance: Perfect for outdoor applications in the building, construction, and renewable energy sectors.
Thermal stability: Maintains elasticity in a wide temperature range, ideal for automotive and building and construction environments.
Excellent sealing performance: Provides long-lasting protection against air, water, and dust infiltration.
Chemical resistance: Withstands exposure to many acids and alkalis.
Sustainability: EPDM supports long product life cycles, making it a valuable material for eco-conscious industries. Recycling possibilities for EPDM products are increasing, and compounds containing recycled ingredients are already available on the market.

Our custom-designed EPDM profiles are engineered to meet the specific sealing needs of each industry we serve, ensuring performance, reliability, and longevity.

What is TPE (Thermoplastic Elastomer)?

TSP refers to sealing profiles made from thermoplastic elastomers (TPEs), which combine the processing advantages of plastics with the flexibility of rubber. These materials are ideal for precision-engineered sealing solutions across industries such as automotive, construction and renewable energy.

Benefits of TPE sealing profiles:

Lightweight & flexible: Easy to handle and install, even in complex geometries.
Recyclable & Eco-friendly: TPEs are available with recycled content, enabling more environmentally friendly products and applications.
Consistent quality: Thermoplastic processing ensures uniformity and tight tolerances.
Weather & UV resistance: Offers good resistance to UV exposure and weathering, and can be enhanced with additives for higher performance.
Customizable properties: TPEs can be multi-extruded (up to four materials in one profile) for added functionality and enhanced design flexibility. They can also be individually colored and modified to create functional surfaces, such as low friction.

Our TPE profiles are engineered to deliver high-performance sealing, tailored to meet the specific demands of each application.
