Ultra-high-molecular-weight polyethylene
Ultra-high-molecular-weight polyethylene is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.
WEGO UHWM Characteristics
UHMW (ultra-high-molecular-weight polyethylene) offers a combination of exceptional properties. This thermoplastic material is tough with superior impact strength. It is corrosion-resistant and exhibits virtually no water absorption. It is also wear-resistant, non-sticking and self-lubricating.
UHMW is an excellent choice for many industrial applications. It reduces noise and vibration, is chemical-resistant and non-toxic and offers excellent mechanical properties even in cryogenic conditions. Characteristics include:
Non-toxic.
Low coefficient of friction.
Corrosion, abrasion, wear and impact resistant.
Extremely low water absorption.
FDA and USDA approved.
Applications for UHMW Thermoplastic.
Chute linings.
Food processing parts.
Chemical tanks.
Conveyor guides.
Wear pads.
UHMWPE TAPE SUTURES ( TAPE)
UHMWPE Sutures are synthetic non-absorbable sterile surgical Sutures which are made of ultra-high molecular weight polyethylene (UHMWPE). Tape provides excellent strength, better abrasion resistance than polyester, better handling and knot security/strength.Tape sutures offered in a tape configuration.
Advantages:
● Abrasion resistance is higher than polyester.
● Round-to-flat structure; provides a smooth transition.
● With its flat surface of the tape structure, it helps to support and distribute the loads.
● Provides larger surface area fixation with its broad, flat, braided structure compared to traditional suture.
● Colored warp strands enhance the visibility.
● Available in many colors: solid black, blue, white, white & blue, blue & black.
UHMWPE SUTURES is a synthetic non-absorbable, ultra-high molecular weight polyethylene (UHMWPE) suture offered in the strip configuration.
Advantages:
● Abrasion resistance is higher than polyester.
● Round-to-flat structure provides an ultra-low profile and maximum strength.
● Available in many colors: solid black, blue, white, white & blue, white & black, white & blue & black, white & green.
● Inter-locking core technology is the technology that provides a strong core with all fibre configurations at the centre of the suture. In regards to this technology, the knot acts as a backbone by better tied and carrying the load.
● Provides excellent flex strength.
● E-braid structure provides better handling and knot strength.
● Provides good visibility with triaxial patterns and vibrant colors.
suture is used for the closure and/or ligation of soft tissue, including the use of allograft tissue for cardiovascular surgeries and orthopaedic procedures.
The inflammatory reaction of suture in tissue is minimal. Gradually encapsulation takes place with fibrous connective tissue.
suture is sterilized with Ethylene oxide.
suture is available with or without needles in pre-cut lengths.
