Sponge Rubber Sheet
Sponge Rubber Sheet
We are known to cater to their clients high quality Sponge Rubber Sheets.
Features:
Sponge Rubber Sheets have a number features that make it a unique material. High compression elasticity and good resilience properties enable it to be used in multiple sectors.
In terms of composition, sponge rubber appears to have the same appearance as regular cellular rubber. However, on closer inspection it is evident that the two are essentially quite different. For one, sponge rubber has a mixed open and closed cell structure. Also, if used for sealing purposes, it requires to be layered with an outer skin. This outer skin makes the sponge stronger and more tear resistant. Even when the skin is punctured or cut, the sheets will not allow passage of air or fluid between cells
However, though they come with a thick outer skin, inside they are very fine and porous. This makes them waterproof as well. Other features include high compressibility, good insulation properties, resistant to high temperature, oils and ageing.
These non-absorbent sheets are highly compressible, resilient, lightweight and provide good thermal insulation. Sponge Rubber Sheets are generally resistant to aliphatic and aromatic hydrocarbons, oils, fuels, ozone and weather, lubricants and animal or vegetable oils. It is also resistant to acids and hot water.
When it comes to manufacturing Sponge Rubber Sheets, primarily two methods can be used: Extrusion or molding.
Application:
When used under light pressure, Sponge Rubber makes the right fit as a sealing material. Available in varying degrees of softness, it is a result of using special mixes that vary according to volume or density. Their usage also includes heavy closing pressures.
For smoother application, they are available in self-adhesive versions (one or both sides) that fit well as a clean, durable seal around circular and square openings. Large containers, tanks and casings find such versions of sponge rubber sheets reliable and cost-effective. This is also workable for large custom cut-outs or items that are punched.
Other applications include gaskets, acting as a barrier to moisture, dust proofing, gas retention, cushioning and sound deadening. But this again depends on what kind of Sponge Rubber Sheet has been chosen. Closed Cell sponges have no connecting cavities, making them ideal for applications where water exclusion and sound and gas retention are important. Open cell sponge has connecting cavities which make the sponge more compressible.
