Industrial sealing applications demand durable, compressible materials that can maintain stable performance under fluctuating temperatures and harsh environments. Silicone sponge seal strip, also known as silicone foam gasket strip, is widely used for sealing, cushioning, vibration damping and thermal insulation across multiple industries. Manufactured by Tengye, our silicone sponge seal strip is produced from premium raw materials with mature foaming technology, delivering consistent softness and long-lasting resilience. We support full customization, making it a preferred sealing component for electrical equipment, new energy, cabinets and machinery projects.
We select high-grade silicone raw materials without inferior fillers to guarantee stable physical performance of finished silicone sponge seal strips. Our complete production workflow includes raw material mixing, vacuum foaming, extrusion or molding, curing, dimension inspection and quality testing. The controlled foaming process creates uniform closed-cell structure, which effectively prevents water, dust and air penetration while retaining good compressibility. Every batch undergoes strict quality checks before shipment to ensure stable quality for bulk orders.
Our silicone sponge seal strip performs reliably over a wide temperature range, normally from -60°C to 200°C. It features outstanding heat resistance, weather resistance and aging resistance. It will not easily harden, crack or deform after long-term exposure to UV, ozone and changing climate conditions. The soft sponge structure provides great cushioning effect and low compression set. It can keep sealing performance after repeated squeezing, ideal for applications requiring frequent opening and closing.
Silicone sponge seal strips are widely adopted in many industrial fields: new energy equipment, electrical cabinets, household appliances, automotive parts, lighting enclosures and mechanical equipment. It works perfectly for dust proof, waterproof sealing, thermal insulation and shock absorption. It can be cut into various shapes and sizes to fit different groove structures.
