What are the types and uses of commonly used reclaimed rubber?
Reclaimed rubber is the key development industry of resource recycling in China. The use of reclaimed rubber not only alleviates the shortage of rubber resources in China, but also solves the problem of environmental pollution caused by random stacking of waste rubber. For rubber products enterprises, the use of reclaimed rubber instead of raw rubber to produce rubber products can reduce the cost of raw materials while ensuring product quality. Common reclaimed rubber on the market includes latex reclaimed rubber, EPDM reclaimed rubber, tire reclaimed rubber, butyl reclaimed rubber, and nitrile reclaimed rubber.
1.latex reclaimed rubber
Latex reclaimed rubber is made of waste rubber silk, rubber cup, waste rubber material and waste latex products as main raw materials through desulfurization and other processes. Latex reclaimed rubber has similar properties to natural rubber and is superior to natural rubber in anti-aging performance and plasticity. Therefore, latex reclaimed rubber is often used to replace natural rubber to produce rubber products. Latex reclaimed rubber is mainly in black and white colors, white latex reclaimed rubber can be used to produce light-colored rubber products with natural rubber as the main raw material, such as automobile interior decoration, bicycle color tire, color cable, color rubber hose, color rubber plate, motorcycle inner tube, light-colored sports shoe outsole, shoe material, etc. Black latex reclaimed rubber conveyor belt, triangle belt, tire casing, rubber plate, rubber pad, rubber strip, seal and other high-strength molded black rubber products.
2.EPDM reclaimed rubber
The raw materials for EPDM reclaimed rubber production are EPDM head rubber, EPDM unvulcanized compound rubber or waste EPDM sealing strip. EPDM reclaimed rubber also has excellent high and low temperature resistance, aging resistance, good weather resistance, ozone resistance and corrosion resistance, and is commonly used to replace EPDM to produce rubber strips, rubber hoses, cable skins, conveyor belts and other high and low temperature and aging resistant rubber products exposed to outdoor use for a long time.
3.tire reclaimed rubber
Tire reclaimed rubber is reprocessed from waste tires. According to the different types of waste tires used, or the performance and indexes of tire reclaimed rubber produced from different parts of waste tires are different. Tire reclaimed rubber is often classified according to fineness, strength and environmental protection. High-fineness tire reclaimed rubber is often used in extruded rubber products with smooth surface requirements such as inner tubes, rubber pipes, cables, etc. High strength tire reclaimed rubber is used to produce high strength black rubber products; environmentally friendly tire reclaimed rubber is often used in drinking water pipes, rubber floors, rubber soles and other rubber products with high environmental requirements.
4.butyl reclaimed rubber
There are two main types of butyl reclaimed rubber, one is butyl inner tube reclaimed rubber produced by waste butyl inner tube, and the other is chlorinated butyl reclaimed rubber produced by waste butyl bottle stopper and bottle cap. Butyl reclaimed rubber has strong air tightness and is mainly used for the production of high air tightness rubber products such as automobiles, motorcycles, bicycle inner tubes, bottle stoppers, bottle caps, etc.
5.nitrile reclaimed rubber
Excellent oil resistance is standard for nitrile reclaimed rubber. Nitrile reclaimed rubber with high rubber content has basically the same performance as nitrile rubber. It can directly replace the original rubber or be used with the original rubber to produce various oil resistant rubber products such as oil pipe, oil resistant rubber plate, oil resistant rubber boots, adhesive tape, rubber diaphragm, etc., which can reduce the production cost of rubber products while ensuring the product performance. Nitrile reclaimed rubber has high air tightness, second only to butyl reclaimed rubber, so it is also commonly used in OProduction of sealing products such as rings, oil seals and oil-resistant gaskets.
