O-Ring Manufacturing Process
O-ring is an annular rubber seal, usually made of elastomer material, used to seal two surfaces in relative motion to prevent liquid or gas leakage. It has excellent elasticity and resilience and can maintain good sealing performance under pressure and temperature changes. How are o rings manufactured? There are several rubber o-ring manufacturing processes, the […]
Stop Making Low Value Commercial Invoices
Are you still cooperating with customers to make a low value commercial invoice? Many exporters think it is human nature for customers to ask for low value commercial invoices to evade taxes. It is okay to help and cooperate to strengthen the cooperative relationship without affecting their foreign exchange collection and tax refund. That was […]

What is CR / Neoprene Rubber?
Neoprene rubber (CR) is obtained by emulsion polymerization of chloroprene (2-chloro-1,3 butadiene), called polychloroprene rubber (referred to as chloroprene rubber), which is a polar, unsaturated, easy to crystallize rubber. It is a general-purpose synthetic rubber developed earlier and has a wide range of uses. The earliest CR put into the market was successfully developed by […]
What is HNBR Rubber?
HNBR rubber, also known as hydrogenated nitrile rubber, is a highly saturated elastomer obtained by special hydrogenation of nitrile butadiene rubber. The butadiene unit in the emulsion nitrile rubber is selectively hydrogenated, but the side nitrile group of the acrylonitrile unit is not hydrogenated. Hydrogenation includes homogeneous catalytic hydrogenation (solution hydrogenation method) and heterogeneous catalytic […]
What is EPR / EPDM Rubber?
EPM rubber (full for Ethylene Propylene Monomer) and EPDM rubber (full for Ethylene Propylene Diene Monomer) belong to the ethylene-propylene rubber family. Ethylene propylene rubber (EPR) is a copolymer synthesized from ethylene and propylene monomers. The weight average molecular weight of ethylene-propylene rubber is 200,000 to 400,000, the number average molecular weight is 50,000 to […]
What is NBR Rubber & Nitrile Rubber?
NBR rubber (also known as Nitrile or Buna-N) is a copolymer of acrylonitrile and butadiene monomers. It is a kind of polymer elastomer obtained by emulsion or solution polymerization of two monomers, butadiene, and acrylonitrile (ACN). Most of the nitrile rubber used in industry is ordinary nitrile rubber obtained by the emulsion method which is […]
What is VMQ / Silicone Rubber?
Silicone rubber (Q) is an elemental organic elastomer obtained by hydrolysis and polycondensation of various dichlorosilanes. Its main chain is mainly composed of Si-O (silicon-oxygen bond) units and a linear polymer with monovalent organic groups as side groups. The molecular chain has both inorganic and organic properties. Silicone VMQ Chemical Formula Table of Contents Types […]
What is FKM / Viton Rubber?
Viton rubber, also known as FKM rubber or FPM Rubber, refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. The introduction of fluorine atoms gives rubber excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance, and atmospheric aging resistance. The earliest ones that were […]
