Product Description
Conforms to UL94 V-0 HF-1 specifications
Our high performance, flame retardant silicone sponge material provides excellent flame resistance as well as low smoke and toxicity properties. This enables you to use our material in a number of electronic and sensitive equipment sealing applications. It is also suitable for use in a variety of dust and water sealing in transportation and automotive applications. We can supply this particular material in a variety of density grades from 250 up to 550kg/m3. Our flame retardant silicone is also available in thicknesses from 0.60mm up to 14.00mm as standard, depending on the specific density and colour you require.
Silicone sponge offers far superior rates of compression compared to solid rubber silicone and other solid rubber compounds. It is also flexible while maintaining a high tensile strength. This enables our flame retardant sponge to create a far superior seal against complex or uneven shapes. Another key property of this material is its outstanding compression set resistance. This ensures that our sponge is able to return to its original shape and thickness after a compression load. This helps to not only create a better seal but also serves to increase the potential service life of the material.
We can supply our flame retardant silicone sponge in a variety of formats in order to suit your specific application. We produce the material in rolls as standard but we can also supply; sheets, strips, gaskets, pads and complex seals to your exact specifications. The wide operating temperature range and low water absorption properties enable you to use our material in both interior and exterior environments. Do not hesitate to get in contact with us to discover how our flame retardant silicone can benefit your application.
Potential Applications
Gasketing & Sealing
Our flame retardant silicone can create a highly efficient gasket or enclosure seal. We regularly supply this material for use in aircraft, automobile or industrial applications. The high compression and compression set resistance of our material enables it to effectively create an air and watertight seal. The cellular structure enables our material to conform to a range of surfaces even under minimal compression.
Gap Filling
The flexibility of our silicone sponge enables you to fill gaps between components in a wide variety of applications. The wide operating temperature range of our material enables you to seal out water and dust as well as reducing noise and vibration. This makes it the ideal material of choice for use in; aircraft, automotive and rail applications. We can also supply this material for use as battery pack gap fillers and seals. During use battery packs expand and contract as they release their energy. The compression set resistance of flame retardant silicone enables it to consistently foam a seal.
Vibration Absorption
Our silicone sponge material is highly effective for use as vibration isolators. This can help to reduce noise as well as damage to delicate components. The cellular structure of our material serves to deflect potential vibrations while also absorbing impacts. In aircraft applications our silicone sponge can seal between two gaps to reduce noise and vibration while creating a moisture resistant barrier. You can also use our material in automotive applications as either a component seal or gap filler to greatly reduce noise transmission. This can help to reduce noise caused by structure-born vibration as well as airborne sound from the road. Impact and vibration absorption is particularly crucial in battery and portable electronic sealing applications. Our material can protect internal components from potential damage caused by drops and knocks.
Material Conversion Possibilities
Here at The Rubber Company we can utilise a variety of sponge rubber conversion tools and techniques. This enables us to cut, shape, drill, join and laminate our materials to match your exact requirements. Rubber sponge materials are manufactured in large blocks, so it is necessary to convert these blocks into usable end products. Our dedicated team can work directly with you every step of the way. This ensures that we use the best methods in order to achieve your desired shape and finish.
