Top 10 silicone extrusion Manufacturers in China 2025 - Blog

Introduction to Silicone Extrusion

Silicone extrusion is a manufacturing process that involves shaping silicone rubber into continuous profiles of various cross - sections. This process begins with raw silicone material, which is typically in the form of a compound. The compound is fed into an extruder, where it is heated and forced through a die. The die gives the silicone its desired shape, such as tubes, rods, seals, gaskets, and other complex profiles.

Silicone extrusion products are widely used in many industries due to their excellent properties. Silicone has high temperature resistance, ranging from - 60°C to 250°C, making it suitable for applications in automotive engines, aerospace components, and industrial ovens. It also has good chemical resistance, weatherability, and electrical insulation properties, which are essential in the electronics, construction, and outdoor equipment industries. Additionally, silicone is flexible, soft, and non - toxic, making it a popular choice for medical and food - contact applications.
