Silicone Foam Strip - Superior Sealing & Cushioning for Demanding Applications

Overview:
Engineered for precision and resilience, silicone foam strip is a lightweight, flexible material with a closed-cell structure, crafted from premium silicone rubber. Its exceptional adaptability, durability, and sealing performance make it ideal for dynamic environments requiring tight seals, vibration damping, and long-term reliability.

Key Features & Benefits:

Extreme Temperature Resistance
Performs flawlessly in -60°C to 200°C+ environments, maintaining elasticity and sealing integrity even under thermal stress.

Reliable Sealing & Protection
Effectively blocks dust, moisture, air, and liquids, making it perfect for weatherproofing, EMI/RFI shielding, and vibration isolation.

Ultra-Conformable & Resilient
Adapts seamlessly to uneven surfaces and tight tolerances, with excellent compression recovery and minimal permanent deformation.

Eco-Friendly & Safe
Odorless, RoHS/REACH compliant, and halogen-free-suitable for medical, food-grade, and consumer applications where safety is critical.

Chemical & UV Resistant
Withstands oils, solvents, and harsh environmental exposure, ensuring long-lasting performance indoors and outdoors.

Common Applications:
Electronics - Enclosure gaskets, shock absorption, EMI/RFI shielding
Automotive - Door/window seals, battery padding, vibration damping
HVAC & Appliances - Air/watertight seals, thermal insulation
