When your application demands extreme high-temperature insulation, sealing and shock absorption, ordinary silicone foam often fails easily-hardening, shrinking or losing resilience under continuous heat. Our High Temp Silicone Foam stands out from generic foam boards with three core advantages you can verify at a glance:
✅ Ultra High Heat Resistance. The high temp foam of Sanpu Silicone is far beyond ordinary grade custom high-temperature resistant silicone formula, short-term peak resistance up to 315℃ (599°F), long-term stable service at 200–250℃ (392°F–482°F).In high temperature ,there is no melting, no cracking, no obvious aging deformation. Silicone sponge sheet is perfect for automotive engine compartment, industrial oven equipment, electronic high-power module thermal insulation sealing-far stronger heat endurance than conventional silicone foam sheets on the market.
✅ Fine Uniform Foam Structure & Ultra-Low Permanent Compression Set .High temp foam has closed-cell fine bubble , fabric texture surface without large holes or uneven density. With strictly controlled low permanent compression deformation rate, long-term pressure & high temperature aging still , silicone sponge material can rebound quickly, not easy to collapse or lose sealing effect. Solve the pain point of ordinary foam easy flattening and poor durability.
✅ Trusted Factory Support | Video Inspection & Online Factory Audit Available . No hidden quality risks! We support real-time video checking of finished foam samples, thickness/ hardness/ cell structure visible directly. Free online remote factory tour: raw material mixing workshop, high-temperature vulcanization production line, physical performance testing room-whole process transparent, verify our mass production capacity and quality control system at any time.
