PE PP anti-acid and anti-alrali plastic bearing

Specifications

PE PP anti-acid and anti-alrali plastic bearing : 

1.HDPE (high density polyethylene)

there two polyolefins offer resistance to almost all acids and bases,detergents and hot water,PE has good insulation properties and is easy to weld,the operating of the HDPE is from -50 to +90 degree

advantage:                                                                                                         disadvantages:

1.light weight                                                                                                     ft surface

2.high toughness                                                                                             2.HF welding not recommended

3.high elongation                                                                                             3.difficult to varnish and glue

4.very good electrical and dielectric properties                                          4.not wather resistant

5.very low water absorption

6.high chemical resitance

7.good protection against stress cracking

8.food safe 

2.PE-UHMW:it's muy buenas propiedades de deslizamiento than HDPE

3.PP (polypropylene ) shows a high mechanical strength,ensile strength, but a low notched impact strength .pp resists stress cracking and it is easy to weld at minus temperatures it can get brittle.the chemical and electrical properties are very good,the temperature ranges between +5  degree and+ 100 degree.

advantage:                                                                                                         disadvantages:

1.low density                                                                                                   1.low oxidation resistance

2.good heat resistance                                                                                 2.low abrasion resistance

3.high tensile strength highsurface strength                                            3.HF-welding not possible

4.high chemical resistance                                                                          4.difficult to varnish and glue

5.food safe
