There are three tests you can perform: Burn Test — light it with a match and smell the smoke. If it smells like candle wax — that indicates polyethylene. Oven Test — place it in an aluminum dish in a degree oven. However, it could warp or distort due to built in stresses. What is the temperature range of UHMW? What are the heat characteristics of UHMW? Does UHMW degrade at higher temperatures? What chemicals affect UHMW?
How does the environment affect UHMW? Wind — no effect Rain or sea water — no effect Sun without protection — depends on thickness and location. The thicker the better. In Florida, Arizona, New Mexico, and other desert areas — less than one year. What is the flammability of UHMW? How can you tell if a sample of UHMW contains regrind? Can UHMW be used for underwater applications?. Yes, UHMW does not absorb water and is chemically inert. How does UHMW protect metal from wearing away?
Is it necessary to grease or oil UHMW? Is UHMW affected by cryogenics? Hydrogen and nitrogen don't affect it, but oxygen could. T weldable? T available in other colors? Is UHMW available in a conductive or anti-static form? Is there an alternative to coating parts?
Can UHMW be ultrasonically welded? Can UHMW be thermal welded? What percentage of parent strength of UHMW can be attained? Can adhesives be used to secure UHMW liners?
What are my installation options for UHMW? Can UHMW be formed into a curved liner? Low moisture absorption, a low coefficient lower than Nylon and Acetal to friction, low energy consumption, low maintenance, and self-lubrication are other few quirks making UHMW stand out from many thermoplastics. Most thermoplastics will utilize the process of polymerization or polycondensation for the production of commercial plastics.
UHMW is consolidated from its monomer ethylene, which is connected to create the base polyethylene byproduct. These molecules are magnitudes longer than the traditionally known HDPE because of its synthesis process based on metallocene catalysts. As mentioned earlier, it is a subgroup of polyethylene, and this consists of really long chains of polyethylene aligning in the same direction.
The length of each molecular chain determines its strength. The distance-dependent interaction between the molecule is weaker for each atom of imbricate between the molecules. However, as the molecules are extremely long, large overlaps become more prevalent, adding more to the capability of handling shear forces from molecule to molecule. Each chain is bonded with others in distance-dependent interactions, making the overall intermolecular strength elevated. Although there are a few, I will still go through the drawbacks of ultra-high molecular weight polyethylene.
The branded plastic material is used in vehicle and personal protection armors, bowstrings, automotive winching, climbing equipment, spear lines for spearguns, cut-resistant gloves, high-performance sails, suspension lines in parachutes, and paragliders, etc. Lower mass and lower elongation to breaking is the key factor for UHMW being used in many industrial applications.
UHMW plastic has the edge over the traditional monofilament line as it stretches less, has a thinner structure, and is more abrasion-resistant. It contains a certain amount of ECTFE and is chemically resistant to chlorine, sulfuric acid, and hydrochloric acid. The UHMW jacketing on the cable provides great mechanical and pliable strength during installation as well as operations.
Ultra-high molecular weight polyethylene is heavily utilized in manufacturing PVC windows and doors: the reason being the heat withstanding capability of PVC-based materials. UHMW has a long history of aligning with medical science as a biomaterial for knee, hips, and spine replacement implants.
The high-performance polymer was first introduced to medical science in by Sir John Charnley became a prominent force as a material for hip and knee replacement in the s. The initial attempt was high unsuccessful, but some early success was seen n the s after the improvement in the development of highly cross-linked UHMW.
Today highly cross-linked UHMW material has become mainstream in clinical hip replacement, at least in developed countries. In the past decade, a trend has been picking pace, and that is the use of fibers for sutures. The sutures are flatter than conventionally used sutures made from polyester and poly-blends making their application in the medical industry easier. UHMW is used for manufacturing the mooring of ships and floating structures. It is designed to easily protect surfaces that are subjected to severe wear.
Having excellent properties such as outstanding abrasion-resistance, superior non-stickiness and a low friction coefficient, Wear Tape is extremely useful as an item kept on hand for machine maintenance and emergency measure.
Parts with severe wear or friction, transportation of materials and packaged goods, chutes and trough liners. We offer a lineup of UHMW polyethylene rails as guides for conveyance containers. Please select the best match for your container shape and line configuration needs. We can also cater to orders for rails in special sizes, custom-made to order, so please do not hesitate to contact us.
