Factory Customized Butyl Flexible Waterproof Natural Non Slip Outdoor Mats

Butyl rubber has good chemical stability and thermal stability, and the most outstanding are air tightness and water tightness. Its air permeability is only 1/7 of that of natural rubber and 1/5 of that of styrene-butadiene rubber, while its steam permeability is 1/200 of that of natural rubber and 1/140 of that of styrene-butadiene rubber. Therefore, it is mainly used for manufacturing various rubber products such as inner tubes, steam pipes, water tyres, dam bottom and gaskets.

Butyl rubber has short double bonds in its molecular structure and high dispersion density of side chain methyl, so it has excellent characteristics of receiving vibration and impact energy. The rebound characteristics of butyl rubber are not more than 20% within a wide temperature range (- 30 to - 50 ℃), which clearly shows that the ability of butyl rubber to receive mechanical functions is superior to other rubbers. The damping property of butyl rubber at high deformation rate is inherent in the chain segment of polyisobutylene. To a large extent, it is not affected by application temperature, degree of unsaturation, vulcanization profile and formula changes. Therefore, butyl rubber was an ideal material for sound insulation and vibration reduction at that time.
