UHMWPEUltra-high molecular weight polyethylene

Produced with state-of-the-art manufacturing technology and accumulated raw material know-how, this UHMWPE (ultra-high molecular weight polyethylene) is recognized worldwide in its industry for technology and quality. It has the highest impact strength of any plastic and better wear resistance than engineering plastics such as POM and nylon 6, and even stainless steel. Its coefficient of friction is only 0.07 without lubrication, and it is FDA certified as safe for direct food contact.

Features

  • Highest impact resistance

    Offers the highest impact strength among plastic materials.

  • Exceptional wear resistance

    Outperforms engineering plastics such as POM and nylon 6, and even stainless steel, in abrasion resistance.

  • Self-lubricating

    The coefficient of friction is only 0.07 without lubrication and can drop to 0.04 with lubrication.

  • Chemical resistance

    Withstands about 80 chemicals and is unaffected by most corrosive substances except strong acids such as concentrated sulfuric and nitric acid.

  • Extremely low moisture absorption

    Keeps its performance where contact with water is frequent.

  • Continuous service temperature 80℃

    Usable down to −100℃ at low temperatures.

  • Cryogenic performance

    Can be used continuously at cryogenic temperatures down to −270℃ while keeping excellent impact and wear resistance.

  • Non-toxic, FDA certified

    Safe for direct contact with food.

Frequently asked questions

What temperatures can UHMWPE handle?

Its continuous service temperature is 80℃ and its low-temperature limit is −100℃. It can also be used continuously at cryogenic temperatures down to −270℃ while keeping its impact and wear resistance.

What sizes of UHMWPE sheet and rod are available?

Sheet thicknesses are 5, 6, 8, 10, 12, 15, 20, 25, 30, 35, 40, 50, 60 mm in white and black, and 8, 10, 12, 15, 20, 25, 30, 35, 40, 50, 60 mm in green. Rod diameters are Φ10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 250, 300 mm in white and Φ15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 90, 100, 120, 130, 140, 150, 160, 170, 180, 200 mm in black.

How does its wear resistance compare with other plastics?

In the specific wear value comparison, UHMWPE scores 100, against PA66 160, HDPE 400, PP 500, PTFE 530, POM 700 and PVC 900. It resists wear better than engineering plastics such as POM and nylon 6, and stainless steel.

Which chemicals attack UHMWPE?

It withstands about 80 chemicals but is affected by strong acids such as concentrated sulfuric and nitric acid. Most other corrosive substances do not affect it.

Can UHMWPE be used for parts that touch food?

Yes. It is non-toxic, safe for direct food contact and FDA certified.
