Is THERMOSLEEVE S Fiberglass Heat Protection Sleeve safe for continuous use at temperatures up to +538°C and short-term exposure up to +705°C?

Yes. THERMOSLEEVE S Fiberglass Heat Protection Sleeve is safe for continuous use at temperatures up to +538°C and for short-term exposure up to +705°C. The product description states it is made from purified, acrylic‑saturated fiberglass braid that does not release loose fibers, allows up to 25% expansion/contraction, and is designed specifically to withstand those continuous and peak temperatures while offering abrasion resistance and stable form for reliable, long‑lasting protection.

Can THERMOSLEEVE S Fiberglass Heat Protection Sleeve be safely used on moving or vibrating components without shedding fibers or losing effectiveness at high temperatures?

Yes. THERMOSLEEVE S Fiberglass Heat Protection Sleeve is suitable for use on moving or vibrating components without shedding fibers or losing effectiveness at high temperatures. The sleeve is made from a purified, acrylic‑saturated fiberglass braid processed at high temperature, producing a clean, non‑friable surface that does not release loose fibers. Its flexible construction allows up to 25% expansion and contraction, so it adapts to changing diameters and movement while maintaining a stable form. It also offers excellent abrasion resistance and is rated for continuous service to +538°C (short‑term to +705°C), ensuring sustained thermal protection in demanding, high‑temperature, vibrating environments.
