By using TPE materials in the functional surfaces of automotive weatherseals, it is possible to produce all-polyolefin systems to replace traditional designs of metal and thermoset rubber. This can have positive implications for cost, weight, and recycling.
At our Automotive Applications Development Center, we have the engineering resources and processing capability to analyze, test, and validate co-extruded applications. A production-capable tri-extrusion line using multi-material dies can integrate as many as three different materials into a single weatherseal profile — including a TPO carrier, a TPE seal, and a cap layer for color or for surface-friction characteristics.
As the leading North American supplier of TPOs to the automotive industry, we have an unmatched portfolio of materials to complement the sealing attributes of our NexPrene TPEs. Bondable NexPrene materials have also been developed specifically for use as corner molds in automotive sealing applications.
