It is required that improving its endurance quality to reach the service life for extending fuel hose and meeting environmental requirements, engine environment is solved
The purpose for the problems such as environment temperature is excessively high and fuel oil medium changes.
Epichlorohydrin rubber is the bipolymer of epichlorohydrin homopolymers (CO) or epoxychloropropane and ethylene oxide
(ECO), or added with Third monomer (propylene oxide) terpolymer.With oil resistant, ozone resistance, heat resistance compares butyronitrile
The features such as rubber is good, and gas permeability is small.
It is main material through having high saturation prepared by chlorination, chlorosulfonation that chlorosulfonated polyethylene rubber, which is using polyethylene,
The body material of special elastic containing chlorine of chemical structure belongs to the specific rubber kind of high-performance quality.Its white in appearance or milky
Elastic material has thermoplasticity.Due to containing chlorine sulphonyl active group in molecular structure, therefore high activity is shown, and especially with resistance toization
It is prominent to learn dielectric corrosion, ozone-resistant oxidation and the performances such as resistance to oil corrosion, fire-retardant, also have the change of anti-times, heat-resisting, anti-ionizing radiation,
Low temperature resistant, anti scuffing and electrical insulating property and excellent mechanical performance.
Therefore, using both the above material the characteristics of, compounds processing technology using rubber, rationally designs formula, make the best use of the advantages and keep away
It is short, it develops a kind of necessary for the high temperature resistant of automobile brake rubber hose outer layer glue, the rubber material of resistance to braking fluid, will generate
Huge economic benefit and social benefit.
