WebTools. Ultra-high-molecular-weight polyethylene ( UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, ( HMPE ), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. [1] The longer chain serves to transfer load more effectively to the polymer backbone by ... WebHDPE (high-density polyethylene): HDPE is known for its large strength-to-density ratio. The density of HDPE can range from 0.93 to 0.97 g/cm3 or 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength than LDPE.
WebMar 18, 2024 · High Density Polyethylene. A strong, cheap, durable plastic with a solid melting point of 110C. HDPE Is one of the more finicky plastics to extrude. It does not stick together well, and because it shrinks a lot when it cools tends to distort readily.
