Neoprene fabric has good physical and mechanical properties, oil resistance, heat resistance, fire resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagent resistance.The disadvantages are poor cold resistance and storage stability.High tensile strength, elongation and reversible crystallization, good adhesion.Resistance to aging and heat.Excellent oil and chemical resistance.Weathering and ozone resistance is second only to epdm and butyl rubber.Heat resistant NBR and its decomposition temperature of 230 ~ 260 ºC, short-term resistant to 120 ~ 150 ºC, in 80 ~ 100 ºC can be use for a long time, have a certain flame retardant.Oil resistance is second only to NBR.Good resistance to inorganic acid and alkali corrosion.Poor cold resistance and electrical insulation.Raw glue storage stability is poor, will produce "self-sulfur" phenomenon, Mooney viscosity increases, the raw glue becomes hard.

1.Neoprene has good flexural resistance.The results showed that the formula of natural rubber rubber with the same degree of cracking was 399,000 times, the formula of 50% natural rubber and 50% chloroprene rubber was 790,000 times, and the formula of 100% chloroprene rubber rubber was 882,000 times.So the product has a good memory, can be arbitrary kneading, deformation will not leave the mark of kneading.The rubber has good shockproof performance, adhesion and sealing performance, widely used in household appliances in the sealing and shockproof parts and other products and mobile phone cases, thermos flask cases, footwear manufacturing.So that the product has a good soft and anti - slip.Softness can effectively foil the user's wrist, reduce wrist strain.Anti-slip can prevent the mouse pad from moving, allowing the user to operate the mouse robustly.

2. Chemical properties of CR diving compound: the double bonds and chlorine atoms in the structure of chloroprene rubber are not active enough to produce chemical reactions easily.So general use is on the product that resistes chemical ability to ask tall, also make the product is not easy ageing, chap.The rubber structure is stable, non-toxic and harmless, widely used in diving materials, sports protection products, fitness products manufacturing.The rubber has good flame retardant, safe and reliable use, mostly used in flame retardant cables, flame retardant rubber hose, flame retardant conveyor belt, bridge support and other flame retardant rubber pieces.The rubber has good water resistance and oil resistance, the rubber is used in oil pipelines and conveyor belts, the above characteristics also make the product can be washed repeatedly, deformation resistance, not easy to aging and cracking and other durable characteristics.Since it is synthetic modified rubber, its price is about 20% higher than that of natural rubber.

To 3. Performance: adapt to various climates, the lowest hardy to 40 ºC, the highest heat resistance at 150 ºC, the lowest general rubber hardy for - 20 ºC, the highest heat resistance is 100 ºC.It is widely used in the manufacturing of cable sheath, rubber hose, building sealing strip, etc.

Low characteristics and scope of application: good weather resistance, resistance to ozone aging, self-extinguishing, good oil resistance, second only to the nitrile rubber, tensile strength, elongation, flexibility is good, but the electrical insulation, storage stability, temperature is - 35 ~ 130 ºC.

Scope of application: it can replace natural rubber to make tires, rubber shoes, rubber pipes, tapes and other general products.

Chemical composition: polymerization from emulsion polymerization of chloroprene as monomer.
