Cross-linked polyethylene
Cross-linked polyethylene, abbreviated XLPE or PEX, is a thermosetting polyethylene with a three-dimensional covalent network, widely used as wire and cable insulation and as plumbing pipe for hot and cold water.
ETFE
ETFE (ethylene tetrafluoroethylene), sold as Tefzel, is a tough, melt-processable fluoropolymer used as lightweight transparent foil cushions on stadiums and botanical gardens, for wire insulation, and in chemical equipment.
High-density polyethylene
High-density polyethylene (HDPE) is a linear, largely unbranched form of polyethylene with 60 to 80 percent crystallinity, making it stiffer and stronger than low-density polyethylene and widely used for bottles, tanks, and pipe.
Ionomer resin
Ionomer resin is a thermoplastic polymer in which metal ions form ionic cross-links between polymer chains, giving toughness, clarity, and strong heat sealing; DuPont's Surlyn, introduced in the mid-1960s, is the best known.
Low-density polyethylene
Low-density polyethylene, or PE-LD, is a branched, flexible form of polyethylene made from ethylene at high pressure, the first polyethylene produced commercially, in 1939, used mainly in film packaging.
Polyethylene
Polyethylene, also called polyethene or polythene, is a thermoplastic polymer and the world's most important plastic by volume, with over 80 million tonnes produced yearly.
Polyethylene upcycling
Polyethylene upcycling is the catalytic conversion of waste polyethylene into higher-value products such as lubricants, waxes, and detergent-range alkylaromatics, targeting only a small fraction of the polymer's carbon–carbon bonds.
Polymer
A polymer is a substance made of very large molecules built from repeated units called monomers, including natural ones like DNA and synthetic plastics like polyethylene.
Tyvek
Tyvek is a family of paper-like sheet materials made by DuPont from flash-spun high-density polyethylene, discovered in 1955 and used in envelopes, house wrap, and protective clothing.
Ultra-high-molecular-weight polyethylene
Ultra-high-molecular-weight polyethylene (UHMWPE) is a polyethylene with molecular weight above 1 million g/mol, giving strength and wear resistance for artificial joints, body armor, and ropes.
