PE/PP/UPE Plastic Bearings (Anti-Acid and Anti-Alkali Bearings)
HDPE PP and the UPE materials have proves can be used for a relativel weak acid-base cross environment(30% Cucl2 solution 30% NaoH solution test OK)it applies to most of the number of acid / base / salt / solvent / oil / gas and seawater corrosion environment. With general plastic bearings oil-free self-lubricating anti-mangenric electrical insulation performance but lower mechanical strength easily deformed it is such resistance to scid-base plastic bearings are not used for larger loads and higher speed in order to overcome this kind of acid-fast The drawback of alkali plastic bearings. In comparision the use of UPE materials have better strength low friction characteristics and low-temperature characteristics(minimum to -150℃)inside and outside the ring material uses of HDPE PP or the UPE ball glass ball stainless steel balls or ceramic.
