1. High and low temperature resistance, common range -50-200 ℃
2. Weather resistance, oxidation resistance, ozone, UV, etc. are very stable
3. Electrical performance: silica gel has excellent insulation, corona resistance and arc resistance.
4. Resistance to oil, chemical reagents and solvents.
5. Good air permeability. It is 30-50 times higher than natural rubber at normal temperature.
6. Physiological inertia. It is non-toxic, tasteless and odorless, does not adhere to human tissue, has anticoagulant effect, and has very little reaction to skin tissue. It is especially suitable for medical materials.
