NEOPRENE is in sheets, usually in 51 * 83 inches or 50 * 130 inches. There are two colors: black and beige. The newly foamed sponge bed has a thickness ranging from 18 mm to 45 mm, and its upper and lower surfaces are smooth. It is also called smooth skin. If the surface of the sponge bed is embossed, it can have better anti-slip performance. The embossed lines include rough embossing, fine embossing, T-embossing, rhombic embossing, etc. The rough embossing is called shark skin, and the fine embossing is called fine skin. The neoprene sponge bed is split. After opening, the splitter becomes an open cell, which is usually pasted on this surface. Neoprene can process 1-45 mm thick splitters as required. The processed NEOPRENE splitters can be bonded to fabrics of various materials, such as LYCRA, JERSEY, TERRY, NYLON, POLYESTER, etc. Adhesive fabrics can be dyed in various colors. The bonding process can be divided into general bonding and solvent-resistant (toluene-resistant) bonding. General bonding is suitable for sports protective equipment, handbag gifts, etc. Solvent-resistant bonding is applied to diving clothing, gloves and other products that need to be used in solvent environment.
Physical properties of Neoprene (SBR CR diving material) 1. Physical properties of Neoprene (diving material): chloroprene rubber has good flexibility resistance. The covering rubber test results of domestic heat-resistant conveyor belts show that the formula of natural rubber compound with the same cracking degree is 399,000 times, the formula of 50% natural rubber and 50% chloroprene rubber compound is 790,000 times, and that of 100% chloroprene rubber compound is 882,000 times. So the product has good memory, can be kneaded at will, will not deform and will not leave the mark of kneading. The rubber has good shock resistance, adhesiveness and sealing performance. It is widely used in household appliances, such as seals and shock-proof parts, mobile phone cover, thermos bottle cover and footwear manufacturing. So the product has good softness and skid resistance. Softness can effectively set off the user's wrist and reduce wrist strain. Anti-skid can prevent the mouse pad from moving, so that users can operate the mouse steadily. 2. Chemical properties of Neoprene: The double bonds and chlorine atoms in the structure of chloroprene rubber are not active enough to cause chemical reactions. Therefore, it is generally used in products with high chemical resistance requirements, which also makes the products not easy to aging and cracking. The rubber has stable structure, non-toxic and harmless, and is widely used in the manufacture of diving materials, sports protection products and body-building products. The rubber has good flame retardancy, safe and reliable use, and is mostly used for flame-retardant cables, flame-retardant hoses, flame-retardant conveyor belts, bridge supports and other flame-retardant adhesives. The rubber has good water and oil resistance. It is used in oil pipeline and conveyor belt. The above characteristics also make the product durable, such as repeated washing, anti-deformation, not easy aging and cracking.
Because it is synthetic modified rubber, its price is about 20% higher than that of natural rubber. 3. Adaptability: To adapt to various climates, the lowest cold resistance is - 40 C, the highest heat resistance is 150 C, the lowest cold resistance of rubber is - 20 C, the highest heat resistance is 100 C. Widely used in cable sheath, hose, construction seals and other products manufacturing and other fields.
