The difference between conventional silicone sponge

strong sealing effect
With different formulas, the tear resistance and tensile rate are more than three times that of conventional silicone sponge. It has longer life service
more heat resistant
We have tested by SGS in 315 ℃(599℉)for 24 hours(without pressure). This kind of high density silicone sponge works well after 24 hrs .Contact us to get the report

The same characteristics as silicone sponge

good sealing effect
Silicone sponge has the ability to withstand compressive loads, can effectively control destructive impact energy, and at the same time prevent the invasion of dust and particles, thereby playing a role in maintaining component safety, preventing faults and reducing unexpected repairs.
Excellent chemical stability,easy to use
Acid and alkali resistance, oxidation resistance. Thanks to the extremely high chemical inertness of silicone itself, even at high porosity, its overall corrosion resistance is still far superior to that of most organic foaming materials (such as PU, EVA, rubber foams).


Long service life
The silicone sponge has excellent UV resistance and anti-aging performance, which not only perfectly meets the requirements of outdoor applications but also makes the service life of this material particularly long, significantly better than that of rubber.
environment-friendly
be decomposed into carbon dioxide and water
During use, silicone foam can be decomposed by microorganisms into carbon dioxide and water, and will not cause pollution to the environment. This biodegradability ensures that silicone foam does not impose a long-term burden on the environment after being discarded and can also be recycled and reuse


be safe to environment and human
Most of the raw materials of silicone sponge are non-toxic and odorless, and do not contain other harmful additives or auxiliaries. Moreover, it has good biological adaptability. Therefore, to a certain extent, it can be regarded as a green material
