上海淞江减震器集团有限公司介绍：DN200NBR煤粉弹性接头产品信息，这里说下DN200橡胶避震接头参数：长度210mm，轴向压缩25mm，轴向拉伸14mm，横向位移15mm。淞江集团为电液集成系统生产一种耐油橡胶接头，主要采用丁腈橡胶生产，代号为N41，其中含量达到50%左右，有含量检测报告，也支持各种第三方检测。

丁腈橡胶主要用于制造耐油橡胶制品。丁腈橡胶中丙烯腈含量(%)有42～46、36～41、31～35、25～30、18～24等五种。丙烯腈含量越多，耐油性越好，但耐寒性则相应下降。它可以在120℃的空气中或在150℃的油中长期使用。此外，它还具有良好的耐水性、气密性及优良的粘结性能。广泛用于制各种耐油橡胶制品、多种耐油垫圈、垫片、套管、软包装、软胶管、印染胶辊、电缆胶材料等，在汽车、航空、石油、复印等行业中成为必不可少的弹性材料。

Shanghai Songjiang shock absorber Group Co., Ltd. introduces the product information of DN200 oil resistant rubber shock absorber joint. Here are the parameters of DN200 rubber shock absorber joint: length 210 mm, axial compression 25 mm, axial tension 14 mm, lateral displacement 15 mm. Songjiang group produces a kind of oil resistant rubber joint for electro-hydraulic integrated system, which is mainly made of NBR, code name is n41, and the content reaches about 50%. There are content detection reports, and it also supports various third-party detection.

 

NBR is mainly used to make oil resistant rubber products. Acrylonitrile content (%) in NBR is 42-46, 36-41, 31-35, 25-30 and 18-24. The higher the content of acrylonitrile, the better the oil resistance, but the lower the cold resistance. It can be used in air at 120 ℃ or oil at 150 ℃ for a long time. In addition, it has good water resistance, air tightness and excellent adhesion. It is widely used in making various oil resistant rubber products, various oil resistant gaskets, gaskets, sleeves, flexible packaging, flexible hose, printing and dyeing cots, cable rubber materials, etc. it has become an indispensable elastic material in automobile, aviation, petroleum, copying and other industries.
