Recycled rubber is the key development industry of resource recycling in China. The use of recycled rubber not only alleviates the shortage of rubber resources in China, but also solves the environmental pollution problem that waste rubber is difficult to digest at will. For rubber products enterprises, the use of recycled rubber instead of raw rubber to produce rubber products can ensure product quality and reduce raw material costs, which can be described as three birds with one stone. Common recycled rubber on the market includes latex recycled rubber, EPDM recycled rubber, tire recycled rubber, butyl recycled rubber, nitrile recycled rubber.
1. Latex recycled rubber
Latex recycled rubber is made of waste rubber silk, rubber cup, waste rubber material and waste latex products as the main raw materials through desulfurization and other processes. Latex recycled rubber has similar properties to natural rubber, and is superior to natural rubber in aging resistance and plasticity. Therefore, latex recycled rubber is often used to replace natural rubber in the production of rubber products. Latex recycled rubber is mainly black and white two colors, white latex recycled rubber can be produced car interior, bicycle color tire, color cable, color rubber hose, color rubber plate, motorcycle inner tube, light color sports shoes outsole, shoe material and other light color rubber products with natural rubber as the main raw material; Black latex recycled rubber conveyor belt, triangle belt, tire tire, rubber plate, rubber pad, rubber strip, seals and other high strength molded black rubber products.
2. Epdm recycled rubber
The raw materials of EPDM recycled rubber are EPDM head rubber, EPDM unvulcanized compound rubber or waste EPDM sealing ring seal strip; Epdm recycled rubber also has EPDM rubber excellent high and low temperature resistance, aging resistance, weather resistance, ozone resistance, corrosion resistance is good, often used to replace EPDM rubber production strip, hose, cable sheath, conveyor belt and other long-term exposure to outdoor use of high and low temperature resistance, anti-aging rubber products.
3. Tire recycled rubber
Tire recycled rubber is reprocessed from waste tires. According to the different types of waste tires used or the different parts of waste tires produced, the performance and index of tire recycled rubber are different. Tire recycled rubber is often classified according to fineness, strength and environmental protection, and high fineness tire recycled rubber is often used in inner tubes, hose, cables, and other extruded rubber products with smooth surface requirements. High strength tire recycled rubber is used to produce high strength black rubber products; Environmentally friendly tire recycled rubber is often used in drinking water pipes, rubber floors, rubber soles and other rubber products with high environmental protection requirements.
4. Butyl recycled rubber
There are mainly two kinds of butyl recycled rubber, one is the butyl recycled rubber produced by waste butyl inner tube, and the other is the chlorinated butyl recycled rubber produced by waste butyl cork and bottle cap; Butyl recycled rubber has strong air tightness and is mainly used in the production of high-air tightness rubber products such as automobiles, motorcycles, bicycle inner tubes, bottle stopper and bottle cap.
5. Nitrile recycled rubber
Excellent oil resistance is the standard of nitrile recycled rubber, high rubber content of nitrile recycled rubber and nitrile rubber performance is basically the same, can directly replace the use of raw rubber, or with raw rubber to produce a variety of oil resistant tubing, oil resistant rubber plate, oil resistant rubber boots, tape, rubber diaphragm and other high oil resistant rubber products, can ensure product performance while reducing the production cost of rubber products; Nitrile recycled rubber has high air tightness, second only to butyl recycled rubber, so it is also commonly used in the production of O-rings, oil seals, oil-resistant rubber pads and other sealing products.
