Polyethylene HD
|
Chemical Name: |
Polyethylene ; |
|
Abbreviation: |
PE, (LDPE, HDPE, UHMWPE) |
|
Common/ Trade Names: |
Ralloy®, Tivar®, Polystone®, Daylon®, Jaylon®, Tufclad®, Pactene® |
|
Properties: |
|
| Colour |
Varies due to branding and PE grades available |
| Form |
|
|
Grades: |
Standard Unfilled, Static Reduced, Ceramic Filled, Ceramic & Carbon Fibre. |
|
Applications: |
Machine parts generally, Chain wear stripsChute liners, Hopper linersGuide strips, Cutting boardsBottling plant change parts, mainly PET bottlesIrrigation and piping, Electrical insulators |
|
Machining: |
Can be tricky as the swarf does not chip, so the long continuous strand of swarf needs to be extracted or it will wrap around the job or tooling. |
|
Types: |
UHMWPE- Ultra High Molecular WeighHMWPE – High Molecular WeightHDPE – High Density LDPE - Low DensityPE also has Re-Processed grades. |
|
Advantages: |
Does not absorb moistureLow coefficient of friction Low material cost Large sheets up to 6 metres longHandles temperatures as low as -270°CCan be bent, formed & welded. |
|
Disadvantages: |
Lower tensile and compressive strength and high thermal expansion up to 3 times that of other engineering plastics available limits its use. |
|
Chemical Resistance: |
Good chemical and acid resistance. |
