An Array of Silicone Rubber Cord Capabilities

We offer both solid and sponge silicone cord, supplying silicone rubber in its cord form, cut to the desired length, or joined into O-rings with a silicone adhesive. We have products available in almost every colour, size and material grade, including special temperature and metal-detectable grades, with our specialists matching colours to any samples provided, including RAL and Pantone numbers.

The extensive and versatile qualities of our silicone cords include:

  • Shore hardness from 20° Shore A to 80° Shore A
  • Manufactured to ISO 3302-1: 2014 E1 tolerances, with tighter tolerances available on request
  • Created in our ISO 9001:2015 certified facility

Unlike other types of rubber, silicone does not become brittle at very cold temperatures, meaning our cords can remain flexible and last longer in these circumstances. Due to their ability to perform very well in harsh environments and extreme temperatures, silicone cords are often supplied, cut and joined into O-rings for sealing applications.

The Viking Extrusion Experience

We have operated as a silicone rubber manufacturer for over 30 years, guaranteeing high-quality silicone rubber cording with short lead times and at a service that beats our competitors on price. No order is too large or small with our ability to meet custom requirements due to having production runs numbering as high as many 1000s of metres or as low as under 10 metres.

The wide range of abilities our team holds ensures we stand out from the competition, meaning whatever modifications you need, the Viking Extrusions team is happy to help.
