China Plastic Bearing with Stainless Ball

PP(Polypropylene) shows a high mechanical strenght, tensile strength, but a low notched impact strengh

1.PP resists stress cracking and it is easy to weld.
2.At minus temperatures it can get brittle
3.The chemical and electrical properties are very good
4.The temperature rande between +5ºC and +100ºC

Advantage:

* Low density

* Good heat resistance

* High tensile strength, high surface strength

* High checical resistance

*Food safe

Disadvantage:

* Low oxidation resistance

* Low avrasion resistance

* HF- welding not possible

* Difficult to varnish and glue

* Not weather resistant
