Coating fiberglass fabric overview

Overview
High temperature resistant fibers generally appear in high temperature applications in the form of textile yarns, meshes, tapes, pipes, cloths, felts, etc. We use post-processing to achieve better application performance:
1.Improving process performance
High silica glass fabric coated with PU material, can improve the abrasion resistance, and meet the requirement of cutting, sewing etc.
2.Improving comfort of human body
Coating organic polymer can reduce discomfort which is caused by the processing of high temperature materials.
3.Improving heat resistance
Coating vermiculite or metal composite can improve the heat resistance.
4. Improving strength
Coating organic precursors can improve the product’s strength and strength retent.
5. Improving anti-corrosion and weather resistance
Coating with excellent weatherability materials like PTFE and silicone, can improve the anti-corrosion and weatherability of products.
6.Improving sealing and protection
Coating with silicone rubber, PTFE and PVC can improve the performance of sealing and protection.
