Ultra-High Molecular Weight Polyethylene (UHMWPE) has been around since the 1950's but was commercialised after over 20 years later. Nowadays they are manufactured using a gel spinning process.

The nature of UHMWPE is so that it gives a very high level of crystallinity after polymerisation allowing it to be able to bear large loads exerted onto it.

Due to UHMWPE's light weight and amazing abrasions resistance, it comes with many benefits:

An unmatchable strength to weight ratio, can reach up to 15 times the strength of steel for same mass

High abrasion resistance

Resistant to fatigue & internal friction

UV stable, allowing it to be suitable for outdoor use

Has a specific gravity lower than water, allowing it to float

Chemically inert except for strong oxidizing acids

Qingdao Yanhang Technology Co., Ltd. produces, develops and sells special fibres, all kinds of high-strength anti-cutting coated yarn, UHMWPE fibres, dyed UHMWPE fibres, and various environmentally friendly materials.

The introduction of the Cratos® range of products allows for reaching of a higher thread modulus. Due to this, the polyethylene has a lesser tendency to break. Due to a density that is lower than water, it gives it the ability to float in water, and offers other advantages such as abrasion resistance and non-reaction with chemicals in the atmosphere.
