Silicone Thermal Insulation Foam Tube is a high-performance closed-cell flexible insulation sleeve designed for high-temperature pipelines, fluid circulation systems, mechanical equipment and automotive thermal management systems. Featuring ultra-low thermal conductivity, excellent heat retention, anti-scald protection and long-term weather resistance, this silicone foam tube effectively reduces heat loss, prevents surface overheating and protects surrounding components from thermal aging. As a premium flexible thermal insulation material, it has become the preferred solution for energy-saving insulation and high-temperature safety protection in industrial, automotive, household appliance and new energy fields.
Material & Manufacturing Process
Our silicone thermal insulation foam tube is made of high-purity industrial-grade silicone rubber raw materials, with stable molecular structure and excellent high-temperature resistance. Adopting one-piece continuous extrusion and closed-cell vulcanization foaming technology, the tube wall forms uniform and dense honeycomb pores with smooth inner and outer surfaces, no hole breakage, no powder falling and no delamination. The independent closed-cell structure locks static air stably, achieving superior thermal insulation performance compared with ordinary sponge tubes.
The finished silicone foam insulation tube features wide temperature adaptability, working stably from -60℃ to 280℃. It maintains softness, elasticity and structural stability after long-term high-temperature baking, cold-hot alternating cycles and continuous mechanical vibration. The material is chemically inert, resistant to oil, weak acid, alkali, UV and ozone aging, ensuring long-term stable service in harsh indoor and outdoor environments. All products comply with RoHS, REACH and environmental protection standards, with optional UL94 V-0 flame retardant grade for higher safety scenarios.
Core Product Advantages
