Material Properties
Silicone foam cord is made by extruding silicone rubber with blowing agents to create a closed-cell structure. This structure prevents water and dust ingress while keeping the material soft and compressible. Compared to solid rubber, the foam cord requires lower compression force to seal, which is useful for lightweight enclosures and joints with limited clamping pressure.
Manufacturing Capabilities
With production experience since 1995, we handle custom requirements for diameter (from 1.5mm to larger profiles), density, hardness, and color (black, red, grey, and others). Materials can be selected for general industrial use or for applications requiring FDA compliance. Production capacity supports both sample orders and bulk shipments.
