Product Description


Material | 100%SILICONE |
Application Scenarios | 1. Construction field: Sealing of doors, windows and curtain walls, waterproofing of pipeline interface 2. Electronics and electrical appliances: Oven door seals, refrigerator seals, dust prevention for instruments and equipment. 3. Medical equipment:Sealing in sterile environments, catheter connections. 4. Industrial machinery: Heat insulation for high-temperature equipment,shock absorption and buffering. |
Product Feature | 1. High temperature resistance (-70°C to 300°C) and excellent low temperature resistance 2. High elasticity and resistance to compression deformation, no deformation after long-term use 3. Resistant to aging, ozone, and ultraviolet rays, with a long service life |
Customized Service | 1. Support customization of shape, size, color and hardness (Shore A 8 - 25 degrees) 2. Provide mold development and sample testing services |
Product Selling Points | 1.Engineered for demanding sealing environments, our silicone foam seal strip delivers reliable long term performance where conventional rubber fails. Combining advanced silicone chemistry with precision extrusion, this Silicone Foam Seal Strip ensures consistent sealing, thermal insulation, and environmental resistance across a wide range of industrial, automotive, and construction applications. It is an ideal solution for buyers seeking durability, stability, and customization in one product. |
2.One of the core advantages lies in its superior temperature resistance and material stability. Manufactured from high quality closed cell silicone foam, the strip operates efficiently within a temperature range of -60°C to 250°C without deformation or performance loss. Unlike EPDM or PVC alternatives, this Silicone Sponge Seal maintains elasticity under extreme heat and cold, making it suitable for high temperature equipment, electrical enclosures, and outdoor installations exposed to UV and ozone. | |
3.Another key feature is its excellent sealing and compression performance. The closed cell structure provides low water absorption, high rebound resilience, and consistent compression set resistance, ensuring long term airtight and watertight sealing. This directly reduces energy loss, prevents dust ingress, and improves system efficiency in HVAC systems, automotive door sealing, and industrial cabinets. Buyers benefit from reduced maintenance frequency and improved operational reliability. |
