Xinhua Xu watches rubber O-ring technology skills

Rubber O-ring (O-rings) is a circular cross-section of the rubber rubber seals, O-shaped cross-section because, so called O-shaped rubber rubber seals, also known as O-rings or rubber O seals, because the rubber O-ring is simple to manufacture, install quickly, sealing strong, and cheap prices, natural rubber O-rings used in rapid reasonable mechanical seal design, lead the way as a rubber O-ring seal element member, is currently on the market the lowest price of the most widely used mechanical seal elements, shouldering the sustained and stable development plans and mechanical seal design topics.

Watch rubber rubber O-ring, selection of raw materials, safety and environmental protection, material via REACH standards. Xinhua Xu high quality nitrile rubber (NBR) is made, cost-effective, its wide temperature range (- 60 ? ~ + 220 ?), the use of fixed pressure up to 1500Kg / cm2 (and reinforcing ring and use), its material properties are high temperature, has excellent weather resistance, ozone resistance and chemical resistance, cold resistance is bad. For most of the oil and solvent resistance have, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils. General temperature range of -50 ~ 150 ?, and the water depth may be about 300 meters.
