High strength UHMWPE yarn for medical suture,surgical thread 10D

UHMWPE yarn

UHMWPE yarn is one of three major hi-tech fibers ( specifically the carbon fiber,aramid,and UHMWPE) , in addition ,it is a super strong polyethylene fiber  that offers maximum strength combined with minimum weight. It is up to 10 times stronger than quality steel and up to 40% stronger than aramid fibers, both on weight  for weight basis. UHMWPE yarn floats on water and is extremely durable and resistant to moisture, UV light  and chemicals. The applications are therefore more or less unlimited.

Basic features of UHMWPE yarn are following:

*High strength: 10 times stronger than the high-quality steel of the same section in intension;

*High modulus: next to the super-class carbon fiber;

*Low density: 0.97, and floatable on water;

*Anti-UV;

*Anti-erosion---anti-acerbity,anti-alkali,anti-seawater;

*extraordinary anti-abrasive flexible .anti-bend.

Based on  UHMWPE yarns so advantages and widely applied in such fields as safety protection ,aviation ,space flight,navigation,electronics ,weapon,shipping  ,building material,sports and so on .Products map of the fiber include bulletproof jacket,ballistic helmet,financial vehicle,ballistic shield,tank,naval armor protection board,parachute hawser,watercraft oceaneering cordage,mountain-climbing rope,fishing net and tread,boat,gig and arrow,pat,ski,man-made nearthrosis and ligament,safety protection cover,anti-impact vessel and so on.

I. Description

UHMW-PE is a super engineering plastic that is probably not as well known as some other engineering plastics but can out perform its relatives in a number of     important areas. UHMW (aka UHMW-PE) offers a combination of excellent properties outstanding abrasion resistance, superior impact resistance, non-sticking and       self-lubricating properties and excellent mechanical properties, even in cryogenic    conditions. UHMW product reduces noise from impact & vibration. It is a      self-lubricating material that is chemical, corrosion, and wear-resistant. And its food safe. The weight is light, the  is 1/8 of the rolled steel. Life is higher than steel. The wear resistance is 3 to 7 times of carbon steel and stainless steel.
