Cable sleeving, such as high-temperature silica or ceramic sleeves, can withstand extreme temperatures (up to 1200°C), providing a protective barrier that prevents heat damage to the cables. We replace metal with plastics such as PA46, PEEK and E/TFE (Tefzel ®) – even in applications involving a high operating temperature – without compromising on quality and performance. Radix specializes in the design and manufacturing of products to meet the most challenging and severe environments, including temperature capabilities from 125°C to 1010°C Your success is our success, and we're committed to. 3M Heat Shrink is a trusted technology to reliably insulate and protect your important applications. 3M Heat Shrink Tubing and Devices provide an easy solution for insulating and protecting wire, cables, connections and components. Our products are trusted in the toughest applications—like glass plants, forging operations, and steel facilities—where. The ÖLFLEX® HEAT 180 MS and 125 MC cables, made from silicone and cross-linked polyolefins, respectively, integrate a tight weave of multi-strand, soft drawn tinned copper wire—an ideal shielding material for short-run cables.
