About our silicone rubber cords

We hold a range of both solid and sponge silicone cords and can supply silicone cord in its cord form, or cut to the desired length, or as joined into O rings with a silicone adhesive. They are available in almost every colour, size and material grade. Including special temperature and metal-detectable grades. 

Unlike other types of rubber, silicone does not become brittle at very cold temperatures. Meaning our silicone cords are able to remain flexible and to last longer in these circumstances. This is also why silicone cords are often supplied cut and joined into O-rings for sealing applications. They perform very well in harsh environments and in extreme temperatures. 

Silicone is also low-toxic and resistant to microbial contamination. Making it useful in the food, beverage and medical industries. It should be noted that silicone does not perform well when subjected to acids, petrochemicals, or any application involving abrasion. Speak to one of our specialists if you have any questions.
