密封圈所使用的材料，橡胶（ Rubber）是种指具有可逆形变的高弹性聚合物材料，在室温下富有弹性，在很小的外力作用下能产生较大形变，除去外力后能恢复原状。 The material used in Haisheng rubber seals. Rubber is a kind of highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. Restore.
T g）低，分子量往往很大，大于几十万，所以很适合用来作为密封件的制作材料。 Rubber is a completely amorphous polymer. It has a low glass transition temperature ( T g) and a large molecular weight, often greater than several hundred thousand, so it is very suitable as a material for making seals.
Rubber is divided into silicone, nitrile rubber, fluorine rubber, EPDM rubber, etc. So, which is the most wear-resistant rubber?
Nitrile rubber , 它也叫做 NBR。 (nitrile butadiene rubber) , it is also called NBR.
It is made from several chemicals. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor electrical properties and slightly lower elasticity.
In addition, it also has good water resistance, air tightness and excellent bonding properties. It is widely used in the production of various oil-resistant rubber products , a variety of oil-resistant gaskets, gaskets, sleeves, flexible packaging, flexible hoses, printing and dyeing rubber rollers, cable adhesive materials, etc., and has become essential in the automotive, aviation, petroleum, copying and other industries. Elastic material.
具有优良的耐油性 ,其耐油性仅次于聚硫橡胶和氟橡胶，并且具有的耐磨性和气密性。 Nitrile rubber seals have excellent oil resistance , its oil resistance is second only to polysulfide rubber and fluorine rubber, and it has abrasion resistance and air tightness. The disadvantage of nitrile rubber is that it is not resistant to ozone and aromatic, halogenated hydrocarbons, ketones and ester solvents, and is not suitable for insulation materials.
Due to the good abrasion resistance of nitrile rubber, it is widely used in industry and life. Haisheng Rubber can tailor-made rubber products for you, please contact us for more information.
