A

Our cable materials are exported to Europe, Southeast Asia, Middle East, Africa, North America, Latin-America and other regions, serving many local cable manufacturers.

A

Our polymer cable materials have been supplied to cable factories across Europe, Southeast Asia, Middle East, Africa, North America and Latin-America. We keep expanding our global customer base year by year.

A

Component A is silane-grafted EPDM elastomer, featuring a soft base matrix with relatively low softening point. When stored under high-temperature conditions, sustained stacking pressure and prolonged static storage, cold-welding adhesion forms between pellet contact surfaces. In addition, moisture absorption will further worsen pellet sticking and caking.
