Xinhua Xu import requirements Hydraulic O-ring rubber formulations

1, the standard basis. The hydraulic O-ring recipe, it must meet the standards of wear-resistant, high temperature, the main indicators of resistance to chipping. Main index formula is guaranteed by a number of factors. So we want to debug the preferred ratio of multiple factors. Historical reference recipe contribution ancestors. Therefore it can not be directly used to use. As technology and economic development, the production of O-rings used in the origin of raw materials, lot numbers have been a great change, once the needs of production must be re-commissioned.

2, related support standards. Such as: wear machine you use, powerful machines and related test equipment type and usage, as well as the calculated data and a series of standards described in the report.

3, summarized above points: the proportion of the material is rubber formulation, performance, process support, test based on the sum of these four aspects, only these four areas to achieve both, standards, is a right, quality formula that can be used .

Hydraulic O-ring American Standard AS568, O-ring Japanese standard P, S, F, O-ring hydraulic GB C92.

Hydraulic O-rings commonly used rubber material Description:

Nitrile rubber (NBR), fluoro rubber (VITON \ FKM), silica gel (SIL), ethylene propylene diene rubber (EPDM).

NBR color is generally black, conventional hardness of 70 degrees.

Fluorine rubber color generally brown-based, conventional hardness of 75 degrees.

Silicone-based transparent color is generally white, conventional hardness of 70 degrees.
