General Purpose Silicone Rubber For Extruded

General Purpose Silicone Rubber For Extruded are specifically designed for multi-purpose applications including molding, injection, extrusion of profiles and wires. The application of this category of silicones is expanded by adding fillers and additives, and also this category of silicones can be produced in different levels of hardness.

Technical Information

TDS

General-usage silicones are a group of PPT-reinforced silicone products, which have become the most widely used group of HTV silicones due to their favorable characteristics and properties as well as reasonable prices. Silicones for general use of Nab Silicon Company, due to the integrated and continuous production process, significant time and energy consumption and special production conditions, have a performance very close to silicones for special and specialized use. One of the benefits of Silicone Nab products is the use of more energy and the additional process of the reactor to separate and extract VOC from the final product.
