Product description

Liquid Silicone Rubber(LSR) - Fumed Silica HJSIL 300 and 380

Hydrophilic Description:

Liquid silicone rubber is also known as two-component additive silicone rubber. This type of rubber has good fluidity, fast vulcanization, can be poured, injection molded, and can be cured at room temperature, which greatly increases the production efficiency of silicone products and reduces production costs. The market share of liquid silicone in the mainstream silicone market is rapidly increasing.

In LSR liquid silicone rubber HJSIL® fumed silica enhances the strength of vulcanized rubber, increasing hardness, modulus, tensile strength and tear strength. Unlike other reinforcing fillers, HJSIL® fumed silica can be used in clear or transparent applications.
