Silicone Rubber Cord

Silicone Rubber Cord

A synthetic elastomer made from a combination of silicon, carbon, hydrogen, and oxygen is known as a silicone rubber cord (SI). It possesses a non-stick, waterproof surface, high levels of compressibility across a wide temperature range, and strong resistance to ozone, ultraviolet light, and weathering. Due to its compliance with FDA and EC regulations, it also has outstanding electrical insulating qualities, is WRAS / WRc approved, and is appropriate for food contact applications. Silicone should not be utilised with acids, ketones, or petrochemicals because it does poorly in applications involving abrasion.

Petron Thermoplast offers silicone rubber cord in a variety of colours and sizes, and it is typically utilised in high temperature sealing applications. Additionally a well-liked choice in the food processing sector, it is frequently vulcanised with RTV silicone glue to produce a strong O-ring. A closed cell silicone sponge cord is also available if more compressibility is needed, and metal detecting silicone cord also helps to lower the danger of product contamination.
