There are two kinds of butyl reclaimed rubber on the market: butyl inner tube reclaimed rubber and chlorinated butyl reclaimed rubber. Both butyl reclaimed rubbers have excellent air tightness and water tightness, heat resistance, ozone resistance and corrosion resistance. Anti-aging is an ideal raw material to replace rubber raw materials produced by butyl rubber to reduce raw material costs. Although the properties of butyl inner tube reclaimed rubber and chlorobutyl reclaimed rubber are basically the same, there are still great differences in raw material source, product color, vulcanization performance and use.
1, different raw materials
The raw material of butyl inner tube reclaimed rubber is waste butyl inner tube. Its product quality is closely related to the brand and model of waste butyl inner tube. Generally, the brand name of waste butyl inner tube in Taiwan is higher than that of other ordinary and miscellaneous small butyl inner tubes. The butyl inner tube reclaimed rubber product produced has higher glue content, stronger strength and better air tightness; the main raw material of butyl chloride reclaimed rubber is waste medical butyl stopper, which has very low gas permeability. Properties, water resistance, heat resistance, ozone resistance and chemical stability, chlorobutyl reclaimed rubber retains these properties.
2, the color is different: butyl inner tube reclaimed rubber is processed from waste butyl inner tube, butyl inner tube is basically black, so butyl inner tube butyl is black block solid; chlorinated butyl reclaimed rubber is mostly light gray The waste butyl cap bottle stopper is used as raw material, and the processed butyl chloride reclaimed rubber is also light gray.
3, different vulcanization properties
The butyl inner tube reclaimed rubber retains the basic structural characteristics of the butyl rubber, while the butyl chloride reclaimed rubber has similar properties to the chlorobutyl rubber; the chlorobutyl rubber is obtained by introducing chlorine gas into the butyl rubber solution, and there is no Saturated bond and allyl chloride, so in addition to retaining the basic properties of butyl rubber, chlorobutyl rubber has the characteristics of high activity, fast vulcanization speed, good flatness and high crosslink density. The vulcanization property and vulcanization effect of the rubber are better, and the heat resistance, compression set resistance and co-vulcanization performance are more excellent.
4, the use of different occasions.
High-quality butyl reclaimed rubber has good elasticity, high strength, air tightness, heat resistance, ozone resistance, aging resistance, chemical resistance, shock absorption and other performance characteristics. It generally replaces butyl rubber to produce butyl inner tube and vulcanized capsule. Steam pipes, dams, gaskets, tire inner liners, shock absorbing materials, anti-virus appliances, heat-resistant products and bridge bearings, etc., reduce production costs; chlorinated butyl reclaimed rubber is used to produce automobile and motorcycle inner tubes and shock-absorbing products. , sealing ring, rubber sheet, sealing strip, chemical anti-corrosion products, building waterproof material, plastic runway, etc., can also be used to produce a variety of light-colored adhesives.
Butyl reclaimed rubber and chlorinated butyl reclaimed rubber have similarities and certain differences. Rubber products manufacturers should choose butyl reclaimed rubber or chlorinated butyl reclaimed rubber according to actual needs.
