Styrene-butadiene rubber 1500 (Styrene-butadiene rubber 1500)

As the base material of gum sugar, our country stipulates that it can be used for gum sugar, and it can be used appropriately according to the production needs.

The abbreviation of Thermoplastic-rubber (TPR) Thermoplastic-rubber (Thermoplastic Rubber-TPR), also known as Thermoplastic elastomer (Thermoplastic Elastomer-TPE) , is a material with both rubber and Thermoplastic properties. Thermoplastic elastomer has many possible structures. The most fundamental one is that at least two mutually dispersed polymer phases are needed. Under normal service temperature, one phase is fluid (making the temperature higher than its Tg-glass transition temperature), the other phase is solid (making the temperature lower than its Tg or equal to Tg), and there is interaction between the two phases. That is to say, the polymer material that shows the elasticity of rubber at normal temperature and can be plastic molded at high temperature has the mechanical properties and service properties similar to rubber, and can be processed and recycled according to thermoplastic, it builds a bridge between plastic and rubber. Therefore, thermoplastic elastomer can be processed rubber products as quickly, effectively and economically as thermoplastic. In terms of processing, it is a kind of plastic; In terms of nature, it is also a kind of rubber. Thermoplastic elastomer has many characteristics superior to thermosetting rubber. At present, there is no uniform name for thermoplastic elastomer. It is customary to use the English letter abbreviation TPR to represent thermoplastic-rubber, and TPE to represent thermoplastic elastomer, both of which are used in relevant data works. For the sake of uniformity, they are all referred to as TPE or thermoplastic elastomer. At present, thermoplastic styrene-butadiene block copolymer is called SBS(styrene-butadiene-styren block copolymer), thermoplastic isoprene-styrene block copolymer is called SIS(styrene-isoprene block copolymer), saturated SBS is called SEBS, the abbreviation of Styrene-ethylene-butylene-styrene block copolymer is styrene-ethylene-butene-styrene block copolymer. Other kinds of thermoplastic elastomer are called by the manufacturer's trade name. Our country also adopts the code of SBS, which means thermoplastic styrene-butadiene-styrene block copolymer, which is customarily called thermoplastic butadiene styrene rubber. 2. Characteristics and application field elastomer is an artificial thermoplastic elastomer with unique performance and has a very wide range of applications. Its excellent product applicability comes from the adjustability and controllability of its special molecular structure, thus showing the following excellent properties: □ superior physical properties: good appearance texture, gentle touch, easy coloring, uniform tone, stable; Adjustable physical properties, providing a broad product design space; Mechanical properties are comparable to vulcanized rubber, but there is no need for vulcanized crosslinking; Wide hardness range, adjustable from SHORE-A 0 degrees to SHORE-D 70 degrees; Excellent tensile resistance, tensile strength up to a dozen Mpa, elongation at break up to more than ten times; Long-term temperature resistance can exceed 70 ℃, the low temperature environment has good performance, and it can still maintain good winding property at-60℃; Good electrical insulation and voltage resistance. It has outstanding anti-skid performance, wear resistance and weather resistance □ excellent chemical performance and resistance to General Chemicals (water, acid, alkali, alcohol solvent); It can be processed in solvent, can be immersed in solvent or oil for a short time; Non-toxic; Good UV radiation resistance and oxidation resistance, can be used in outdoor environment; Good bonding performance, the appropriate adhesive technology can be directly bonded to the surface of synthetic leather or artificial leather. □ production and processing advantages without vulcanization, it has the characteristics of traditional vulcanized rubber, saving vulcanising preparations and accelerator and other auxiliary raw materials; Suitable for injection molding, compression molding, hot melt and dissolved coating and other processes; Edge materials, surplus materials and waste materials can be completely recycled and reused without changing performance and reducing waste; Simplify processing technology, save processing energy consumption and equipment resources, short processing cycle, reduce production cost and improve work efficiency; the processing equipment and process are simple, saving production space and reducing the unqualified product rate; The product is non-toxic, non Strang odor, no harm to the environment, equipment and personnel; The material can be used repeatedly, and the side and foot waste can be recycled. It can be said that there is no waste in production; There are few processing aids and additives, it can save the cost of product quality control and inspection; Product size precision is high, quality is easier to control; Material proportion is small, and adjustable; Can be directly connected with PP, ABS and other plastics are mixed to make special plastic alloy. Elastomer has superior physical and chemical properties and is easy to process. At the same time, the product also has the environmental protection advantages of non-toxic, pollution-free and recyclable secondary processing. Therefore, it is widely used in many industrial fields, such as toys, sports equipment, shoe materials, stationery, hardware, electric tools, communications, electronic products, food and beverage packaging, household appliances, kitchen supplies, medical equipment, automobiles, construction projects, wires and cables, etc. What is more valuable is that she is a high-quality material leading the design of new products and market orientation-its soft texture and adjustable physical properties, hardness, suitable for a variety of processing techniques and environmental protection advantages-providing a huge space for product designers, which undoubtedly adds value to your innovative products, leading the market trend has provided great help.
