Silicone Sponge Strips
Crafted from the fine closed-cell cellular silicone rubber, our silicone sponge strips emerge through a precise process of extrusion or precise slitting from calendared sheeting. This versatile product line boasts an expansive array of dimensions, colours, and specialized grades, offering a truly customizable solution to meet your specific requirements. The unique nature of sponge allows for enhanced levels of compressibility and weight reduction over standard silicone rubber strips.
The ability to fill uneven gaps / cavities is a leading attribute of silicone sponge strips. This along with the protection it can offer against moisture and dust ingress means this product is widely used in sealing environments.
