Chloroprene rubber is a relatively small variety of synthetic rubber to be more special, is the early realization of industrial production of a single sex Hugh, with weather resistance, flame and ozone resistance, heat resistance, and cold and oil and flexing and strength and other more comprehensive characteristics, can be used in harsh and harsh environments, and the products have a long service life, there is no elastomer can fully replace the chloroprene rubber.

Chloroprene rubber and chloroprene rubber structure is similar, the difference is that chloroprene rubber in the polar negative electrically charged groups to replace the natural like more in the methyl, thus improving the chloroprene rubber and ozone, and oil and thermal properties, in short, it has excellent weathering, and ozone, chemical corrosion, oil resistance, etc., and its comprehensive physical machine performance is also better, so the use of chloroprene rubber is very broad, both as a general-purpose rubber and as a special rubber use. Rubber can also be used as a special rubber. Its main physical and mechanical properties since the amount of.

1. Strength of neoprene rubber

Chloroprene rubber tensile properties similar to natural rubber, its raw rubber has a high tensile strength and elongation at break, belonging to the self-reinforcing rubber, chloroprene rubber molecular structure, molecular chain contains chlorine atom polar groups, increasing the intermolecular forces. Therefore, under the action of external forces, it is easy to stretch and crystallize (self-reinforcing), and it is not easy to slip between molecules. In addition, the molecular weight is larger (2.0~200,000), so the tensile strength is larger.

2. Excellent aging resistance

Chlorine atoms connected to the double bond of the molecular chain of chloroprene rubber makes the double bond and chlorine atoms become inactive, so its vulcanized rubber fire storage stability is good, not easily affected by the role of heat, oxygen, light in the atmosphere, the performance of excellent aging resistance to weathering, and ozone and heat-resistant) performance, and its aging performance, especially weathering, and ozone-resistant performance, second only to ethylene-propylene rubber and the rubber base in the general rubber, far superior to the natural rubber, and its thermal performance is better than natural rubber and butyl rubber, and the natural rubber. Heat resistance is better than natural rubber and styrene-butadiene rubber, similar to butyl rubber, can be used for a short period of time under 150C, and can be used for as long as 4 months under 90- 110°C.

3, excellent flame resistance of high engineering like brain iron is very good in the brain, it has the characteristics of not self-lazy, contact with the flame can be, but limited to the flame that is self-extinguished, this is because of the gas industry like the case, in the high mixing of the work can be divided into more than the gas in order to restore the body with the body and make the fire chase!

4, excellent oil resistance, solvent resistance

Chloroprene rubber's oil resistance is second only to butyl rubber and better than other general-purpose rubber. This is because chloroprene rubber molecules contain polar chlorine atoms, increasing the polarity of the molecule. The chemical resistance of neoprene rubber is also very good, except for strong oxidizing acid, other acids and alkalis have almost no effect on it, and the water resistance of neoprene rubber is also better than other synthetic rubbers. The neoprene cloth produced by our company uses fiberglass cloth as the base material and is coated with high-temperature and oil-resistant neoprene rubber, which gives the cloth good oil resistance, high-temperature resistance and excellent tensile strength.

Application

Used in the production of tarpaulins, inflatable buildings, airbags, oil booms, dams and flame retardant tape.
