High quality UHMWPE fiber for UD cloth body armor

UHMWPE Fiber

UHMWPE yarn is one of the three high-tech fibers (specifically carbon fiber, aramid and UHMWPE), and in addition, it is an ultra-strong polyethylene fiber that provides maximum strength and minimum weight. It is 10 times stronger than premium steel and 40% stronger than aramid fiber, both by weight. UHMWPE yarns float on water and are extremely durable and resistant to moisture, UV rays and chemicals. So the applications are more or less unlimited.

The basic characteristics of UHMWPE yarn are as follows.

* High strength: the strength is 10 times that of high-quality steel with the same section;

* High modulus: second only to super carbon fiber

* Low density: 0.97, can float on the water

*anti-UV

*Anti-corrosion --- anti-acid, anti-alkali, anti-seawater;

*Extraordinary anti-abrasion, flexibility, anti-bending.

Based on such superior performance of UHMWPE yarn, it has become one of the rapidly developing high-tech materials in recent years, widely used in safety protection, aviation, aerospace, navigation, electronics, weapons, shipbuilding, building materials, sports and other fields, medical treatment, etc. . Products made from this fiber include body armor, bulletproof helmets, financial vehicles, bulletproof shields, tanks, naval armor shields, parachute cables, marine engineering ropes for ships, climbing ropes, fishing nets and pedals, boats, sailboats and arrows, rackets, Skis, artificial joints and ligaments, safety shields, impact-resistant containers, etc. 1

1. Description

UHMW-PE is a super engineering plastic that may not be as well known as some other engineering plastics, but it outperforms its counterparts in many important areas. UHMW (aka UHMW-PE) has excellent wear resistance, excellent impact resistance, non-stick and self-lubricating properties, and excellent mechanical properties, even at low temperatures. UHMW products reduce noise from shock and vibration. It is a self-lubricating material that is resistant to chemical attack, corrosion and wear. It's food safe. Light weight, 1/8 of steel. Life is higher than steel. The wear resistance is 3 to 7 times that of carbon steel and stainless steel.
