Rubber insulation material, with a smooth and uniform outer skin, without obvious wrinkles or bumps. Rubber insulation materials, when exposed to fire, have a relatively higher critical point for the oxygen index OI required for combustion, resulting in high safety performance during combustion. Rubber insulation material has extremely low smoke concentration during combustion, low smoke density level, and safe and reliable combustion performance. Rubber insulation material has a long-lasting and stable initial thermal conductivity, and a long service life, so the insulation life of the material is also longer. Rubber insulation materials have a strong ability to prevent the penetration of water vapor in the air, with a moisture resistance factor of μ ≥ 7000~8500, resulting in better moisture resistance, vapor barrier, and anti condensation effects. Rubber insulation materials have strong resistance to ozone (O3 ↑), sun exposure, and ultraviolet radiation, are not easily aged, and have a long service life.
