Silicone Foam Sealing Strip｜High-Temp Sealing Solution

【Meta Description】

High-quality silicone foam sealing strips with excellent heat resistance and waterproof performance. Custom sizes available. Ideal for industrial use.

【Content】

Silicone foam sealing strips are high-performance sealing materials known for their outstanding heat resistance, compression resilience, aging resistance, and electrical insulation. They are widely used in industrial, electronic, electrical, construction, and medical sectors as reliable sealing solutions. Made from premium silicone materials, these strips are lightweight, flexible, and exhibit excellent rebound, efficiently sealing gaps and blocking moisture and dust to enhance equipment durability.

Our silicone sponge strips are available in a wide range of types and specifications. Custom options are offered to meet the unique demands of complex environments such as high temperatures, vibrations, and humid conditions. Compared to traditional rubber sealing strips, silicone foam strips provide superior temperature resistance (from -60°C to +250°C) and longer service life.

Typical applications include: battery pack sealing for EVs, dust-proofing of control panels, vibration damping for appliances, waterproofing for medical equipment, and LED lighting protection.

Silicone foam is eco-friendly, non-toxic, and compliant with RoHS and FDA certifications, ensuring product safety and performance for industries with stringent quality standards.

FAQs:
