Yiho CZPTtek CZPT diverse rubber oring/rubber sealing/rubber gakset/rubber button/rubber pump diaphragm and so on for each and every customer,especially neoprene rubber sealing.If you are interseted in nneoprene rubber sealing or yet another rubber goods,many thanks get in touch with us freely!

natural rubber sealing


If the sort of all-natural rubber sealing are “O”,then we need specific informaion as following:.O ring essential parameter verify:important parameter of o ring :

content, internal diameter(ID), part cross dimensions(C/S), hardness, shade, particular perform issue

For a quickly quotation, enable me know the amount you need.

If you can send out me sample, I can check these parameter by our advanced tools.

If you give me the drawing, that will be quite clever.


Advantages of  natural rubber sealing:

one.Optimum heat resistance

two.Excellent chemical resistance

3.Outstanding air tightness

seven.Anti-plasma qualities


Down sides:

one.Minimal temperature resistance characteristics

two.Raw substance rates larger

three.Manufacturing and processing more challenging


Application places:

Perfluorinated merchandise are commonly employed in this substance is mostly used for semiconductor, army, aerospace and other chopping-edge places. The scope of software involves the method of PVC, CVD and etching procedure and a assortment of higher vacuum sealing approach.
