The rubber extrusion process is when an extrusion machine forces the synthetic or natural rubber material to take shape through a die under high pressure. The silicone rubber is shaped into a flexible state and then vulcanized to harden the piece into the desired product.
Silicone extrusions are designed to create oven seals, electrical cables and wire insulation, seals, strips, sheets, gaskets, tubes, and other profiles. Silicone rubber extrusion profiles are ideal for several applications. Such as building construction, electric wires, and cables, automotive, industrial equipment, etc.
