Special rubber is a synthetic rubber with special properties and special uses that can be used under harsh conditions. It is used with Dalian marine valves. Such as fluororubber resistant to 300 ℃ high temperature, strong corrosion, ozone, light, weather, radiation and oil; Silicone rubber resistant to low temperature of - 100 ℃ and high temperature of 260 ℃, low temperature dependence, low viscous flow activation energy and physiological inertia; Acrylic rubber with good heat resistance, solvent resistance, oil resistance and electrical insulation.

Others include polyurethane rubber, polyether rubber, chlorinated polyethylene, chlorosulfonated polyethylene, propylene oxide rubber, polysulfide rubber, etc. they also have excellent unique properties, which can meet the specific requirements that general general rubber cannot meet, and play an important role in national defense, industry, science and technology, medical and health fields.
