Neoprene/chloroprene rubber -CR .

Neoprene, chloroprene alpha-polymerization hmanga siam synthetic rubber chi khat, a bul berah chuan 2-chloro-1,3-butadiene chu raw material lian ber atan hmanga siam a ni.Physical leh mechanical property tha tak tak a nei a, oil, lum, meialh, leh ozone te chu a tling tawkin a do thei bawk. Acid leh alkalis bakah chemical reagents te pawh a do thei bawk. Tensile chakna sang tak, elongation, leh reversible crystallinity, adhesion tha tak a nei bawk. tar leh heat resistance. Oil resistance leh chemical corrosion ah pawh a tha hle. Weather resistance leh ozone aging resistance chu ethylene propylene rubber leh butyl rubber hnuah a ni. Heat resistance hi NBR nen a inang a, a lumna chu 230-260°C a ni a; Hun rei lote chhunga do theihna chu 120-150°C a ni a, hun rei tak chhung 80-100°C-ah hman a ni a, chutah chuan meialh-retardant property engemaw zat a nei bawk. Inorganic acid leh alkali te laka corrosion resistance tha tak a nei. Rubber technology lama hriatna tam tak leh thumal pum huapa sem darhna kawng zau tak atanga siam herchy rubber. Ram 15 chuang USA, Russia, Brazil, Argentina, Korea, Germany, Italy, Australia, India, etc. doletna.

Tensile chakna sang tak, elongation leh reversible crystallinity a nei a, adhesion tha tak a nei bawk. Tar leh lum laka inven theih a ni. Oil leh chemical corrosion laka invenna tha tak a ni. Weather resistance leh ozone aging resistance hi ethylene propylene rubber leh butyl rubber hnuaiah pahnihna a ni. Heat resistance hi NBR nen tehkhin theih a ni a, decomposition temperature 230-260°C, hun rei lote chhunga resistance 120-150°C, hun rei tak chhunga 80-100°C-a hman, flame retardancy degree engemaw chen nei nen tehkhin theih a ni. Inorganic acid leh alkalis laka invenna tha tak.

Rubber technology lama hriatna tam tak leh thumal pum huapa sem darhna kawng zau tak, USA, Russia, Brazil, Argentina, Korea, Germany, Italy, Spain, Australia, leh India etc. te hnena thawn chhuah herchy rubber hi a ni.
