UHMWPE is a thermoplastic engineering plastic, which integrates the superior properties of all plastics. The five characteristics of impact resistance, wear resistance, chemical corrosion resistance, self-lubrication and impact absorption performance are the highest values of all existing plastics at present.
Diameter | Roundness | Diameter tolerance | Lengths |
30-40 | ≦3 | ±1.5 | 1000 |
50-70 | ≦5 | ±2.5 | |
90-140 | ≦6 | ±3.0 |
Indications Name | Unit | Test Method | Indicators |
Density | g/cm³ | ASTM1505 | 0.94 |
Fracture Strength | Mpa | D638 | 42 |
Elongation at break | % | D638 | 350 |
Impact Strength | Kj/m² | D256 | ≥100 |
UHMWPE can even act in liquid nitrogen or liquid nitrogen, its use temperature can reach below -269 ℃, still has a certain mechanical strength.
UHMWPE has excellent wear resistance, the higher the molecular weight, the better the wear resistance of the material.
UHMWPE has very low water absorption.
UHMWPE chemical stability is very high, in a certain temperature, concentration range can resist acid, alkali, salt and other corrosive media.
UHMWPE tasteless, non-toxic, odorless, not corrosive in itself. The US food and drug administration(FDA) and the United States department of agriculture (USDA) allows it for special occasions in contact with the food and drug. Therefore, UHMWPE is suitable for food, medicine and other industies with higher requirements for hygiene conditions.
