Tengye | High Temperature Silicone Foam Sponge Tube Industrial thermal protection often requires flexible, heat-resistant tubing that can endure extreme thermal cycling. Our high temperature silicone foam sponge tube is engineered to deliver reliable thermal insulation, cushioning and sealing for industrial, energy and electrical equipment. Manufactured at our strong factory with premium raw materials, this silicone foam tubing maintains stable performance under harsh working conditions.
We select high-quality silicone raw materials without third-party brand reliance. The whole production flow includes material mixing, foaming, extrusion or molding, vulcanization, dimensional inspection and final quality testing. Uniform closed-cell honeycomb structure is formed inside the tube wall. Strict quality control runs through every step to guarantee consistent, excellent quality for every batch.
The silicone foam sponge tube features outstanding elasticity, low thermal conductivity, UV and ozone resistance, aging resistance and buffer performance. ✅ Operating temperature range: -60°C to 280°C, short instant peak up to 300°C ✅ Remains soft and flexible, no hardening, cracking or shrinkage after long heat cycles ✅ Closed-cell structure provides heat insulation, anti-scald, moisture and dust resistance ✅ Optional flame retardant formula for high safety industrial environments
This high temperature silicone foam sponge tube is widely adopted in new energy thermal management, industrial heating equipment, electrical cabinets, pipeline insulation, automotive high-voltage harness protection and machinery thermal insulation. It works well in continuous high heat, cold-hot alternation, outdoor exposure, humid and slightly corrosive industrial environments. It can reduce heat loss, prevent scalding and protect wires and pipelines from thermal aging.
We support custom manufacturing by drawings or samples, accept OEM and ODM orders. ✅ Fast quotation ✅ Rapid sample delivery ✅ Stable lead time guarantee ✅ One-stop silicone rubber service and efficient engineering solutions
