A flexible, chemical-resistant silicon rubber-coated aramid fabric engineered for use in extremely low (-321°F) and moderate (392°F) temperatures.
  • Best in flexibility; perfect for high flexing applications
  • Can withstand temperatures between -321°F to 392°F
  • Medium weight and chemical resistant

Material Specification No. 1134

Raw materials are not sold separately, please contact the sales department for any special requirements.


The SRA-41 fabric is perfect for commercial industries that need shielding from extremely low and moderately high temperatures.

The SRA-41 material is a 0.041” thick silicone-coated para-aramid fabric that is perfect for heat shielding solutions. The medium weight material is flexible and chemical resistant; fluids simply bead off the jacketing. The protective fabric can handle temperatures as low as -321°F and as high as 392°F, making this an ideal choice for wires and cables exposed to extreme temperatures. The SRA-41 material pairs well with zipper and snap button closures, creating an easily applied and accessible solution.
