PE 1000 is a pure, unmixed ultra-high-molecular-weight polyethylene (UHMW-PE) with a molecular weight of 4.4–9.2 million g/mol.
It has the following properties:
Molecular weight approximately 4 million (Light Diffusion Method)
Low specific weight 0.94g/cm3
Extremely high notch impact strength
High Pactene (Ultra High Molecular Weight Polyethylene)elasticity
Chemical resistance to most corrosive agents
Self lubricating
Unusually low abrasion guarantees long life
Water repellent
Favourable electrical properties permit many uses in the manufacture of electrical devices, especially high voltage and high frequency devices
No sticking or freezing to the surface
Physiologically harmless, as used in food industry
Stable to -260oC Used in cryogenics and freezing.
