Thermal Insulation
Suntex provides all the materials necessary for thermal insulation covers, which have been widely used in the oil, natural gas, maritime, power, aerospace, and other industrial sectors.

The outer layer protects the insulating material from environmental factors such as moisture, chemicals, and physical damage.
This layer is often made from durable materials like silicone, PU, PTFE, and aluminum fabrics.
Silicone coated fiberglass fabric
Silicone coated fiberglass fabric is ideal for thermal insulation covers due to its high temperature resistance, durability, moisture and chemical resistance, low thermal conductivity, and UV protection.
