Hydraulic seal material NBR

Various types of hydraulic seals XinhuaXu rubber supply, hydraulic seals, high quality and reasonable price, complete specifications, and conventional products perennial with large inventories.

XinhuaXu hydraulic seal surface is smooth, no needle, no edges, to an accuracy of ± 0.03mm ± 0.08mm. For the hydraulic industry, the existing American standard, Japanese standard, European standard, GB, and other specifications of the tens of thousands hydraulic seal.

Nitrile rubber (NBR) Hydraulic seals: this material highest temperature up to 130 degrees, has a hardness of 50-90 degrees, complete specifications, it has good mechanical properties, resistance to mineral-based oils and grease.

(Nitrile Rubber) by the acrylonitrile and butadiene polymerization, acrylonitrile content from 18% to 50%, the higher the acrylonitrile content, resistance to petrochemical oil hydrocarbon fuel the better, but the low temperature performance worse, the general temperature range of -25 ~ 100 ?. NBR rubber seals and hydraulic seals is currently one of the most commonly used pieces of rubber.

Hydraulic seals NBR with good resistance to oil, water resistance, solvent resistance and resistance to high pressure oil properties. And with good compression distortion, wear and elongation force.

The disadvantage:

Not suitable for polar solvents being, such as ketones, ozone, nitro hydrocarbons, MEK and. - For the production of fuel tank, oil tank and oil-based hydraulic oil, gasoline, water, silicone grease, silicone, diester Department of lubricating oil, hydraulic oil, glycol-based fluid medium used in rubber parts, especially the sealing parts . Can be said is the most widely used, the lowest-cost hydraulic seal.
