Web14 Oct 2011 · "UHMW has one of the highest impact strengths of any thermoplastic and has excellent abrasion resistance, tensile strength, energy absorption, resistance to stress, cracking, and coefficient of friction properties. WebHDPE is often used as a vessel or container, or for marine applications. On the other hand, UHMW is also low-cost and primarily used for applications that require extreme strength and abrasion resistance. This is an extremely popular plastic for wear industrial applications that require constant friction between moving parts over time.
Web8 Mar 2024 · High-Density Polyethylene (HDPE) This form of polyethylene has gained popularity over the years. It is the more rigid form of polyethylene. It has higher tensile and impacts strength. HDPE has a much lower level of branching than LDPE. The level of branching gets reduced by having a more controlled polymerization process. Web26 Oct 2024 · HDPE also has high tensile strength but is stiffer than LLDPE. This makes HDPE a better choice for some plastic tanks , and for products such as boat docks, cargo tanks, and underground vessels. HDPE rotational molding can also support products, such as those used in the food processing industries, that must meet guidelines from the Food …
WebPoor Choices: Nylon, UHMW, HDPE, LDPE Chemical Resistance: Chemical resistance of plastics is variable. Some materials show an almost universal resistance to chemicals while others are very sensitive and stress crack when exposed. Best practice is to consult a reference guide for a specific chemical/plastic interaction.
