包覆o型圈是一种由硅橡胶或氟橡胶等材料制作而成的内芯与相对比较薄的PTFE等各种外覆材料组合而成的密封件。
目前主要用于泵、阀门、反应容器、机械密封、过滤器、压力容器、散热器、锅炉、管路法兰，气体压缩机等相关设备。主要应用的行业有机床、船舶、汽车、飞机制造、石油化工、炼油、制冷工程、食品加工业、制药工程、造纸业、工程机械、建筑机械、仪器仪表等。
Covered o-ring is a kind of seal composed of a relatively thick inner core made of silicone rubber or fluororubber and other relatively thin outer covering materials such as PTFE.
Our company can customize products of various colors and shapes according to the drawings, samples, specifications and materials provided by customers.
main feature:
It has excellent chemical resistance and can be used in almost all chemical media, such as strong oxidizing and strong reducing solvents, and strong corrosion resistance of solvents such as strong acids and alkalis; the applicable temperature range is very wide, from minus 200 ℃ to above zero 260℃; very good compression resistance, greater than or equal to 30%; very small friction coefficient, only between 0.1~0.2; good swelling resistance ≤ 0.1%; extremely high pressure resistance, up to 60Mpa; Sealing continuity can increase the service life by more than 5 times.
Material Description:
The two outer covering materials, FEP and PFA, are very similar in nature, but the high temperature resistance of PFA material is better than that of FEP material. The applicable temperature range of FEP is -60℃~205℃, and the applicable temperature range of PFA- 60℃~260℃.
Application areas:
At present, it is mainly used for pumps, valves, reaction vessels, mechanical seals, filters, pressure vessels, radiators, boilers, pipeline flanges, gas compressors and other related equipment. The main application industries are machine tool, ship, automobile, aircraft manufacturing, petrochemical, oil refining, refrigeration engineering, food processing industry, pharmaceutical engineering, paper industry, construction machinery, construction machinery, instrumentation, etc.
我司能按照客户提供的图纸、样品、规格及材质等开模加工定做各种颜色与外形的产品。
具有良好的耐化学性能，可适用于几乎全部的化学介质，如强氧化和强还原性溶剂，抗强酸强碱等溶剂的腐蚀性很强；适用温度范围非常广，从-200℃到260℃；耐压缩性非常好，大于等于30%；抗摩擦系数较小，仅在0.1~0.2之间；具有良好的抗溶涨性≤0.1%；及耐高压，可达到60Mpa；拥有良好的密封持续性，能够增加5倍以上的使用寿命。
FEP和PFA这两种外覆材料本质上是非常相似的，不过PFA材料的耐高温性要比FEP材质更好一些，其中FEP的适用温度范围-60℃~205℃，PFA的适用温度范围-60℃~260℃。
