Espolex® WT501 Black

Espolex® WT501 Black is a thermoplastic elastomer with strong adhesion to EPDM, Polypropylene compounds, and Polyethylene. It processes like a thermoplastic and acts like a rubber. It is used for various applications such as body seals and weather seals, TPV corner mold, interior or exterior trim, and injection molded parts. This product is suitable for Injection Molding.   Applications: Body Seals/Weather Strip Seals  TPV Corner Molds (Injection mold with insert molding of two straight extruded body seals to join the pieces to create a corner)    Features: Strong adhesion to EPDM, PP, TPO, and PE. Flexibility    Benefits: Anti-squeak (noise) with a glass window
