Polyethylene glycol (PEG; / ˌ p ɒ l i ˈ ɛ θ əl ˌ iː n ˈ ɡ l aɪ ˌ k ɒ l,-ˈ ɛ θ ɪ l-,-ˌ k ɔː l /) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine.PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight.The structure of PEG is commonly expressed as H−(O−CH 2 ...

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene.It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber.

PEG 400 (polyethylene glycol 400) is a low-molecular-weight grade of polyethylene glycol. It is a clear, colorless, viscous liquid. Due in part to its low toxicity, PEG 400 is widely used in a variety of pharmaceutical formulations. Chemical properties. PEG 400 is strongly hydrophilic.

Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins.Linear low-density polyethylene differs structurally from conventional low-density polyethylene (LDPE) because of the absence of long chain branching.

Polyethylene terephthalate can be depolymerized partially or completely to yield the constituent oligomers or the monomers, MEG and PTA or DMT. The main processes are glycolysis, methanolysis or hydrolysis. After purification, the oligomers or monomers can be used to prepare new recycled polyethylene terephthalate ("r-PET"). The ester bonds in ...

ポリエチレンテレフタラート（英: polyethylene terephthalate ）は、ポリエステルの一種である。 ポリエチレンテレフタレートとも呼ばれる。. 略称は頭字語でPETと綴り、日本語では「ペット」、英語では「ピーイーティー」と読む。 ペットボトルの名称はこれに由来する。

Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection …

Hypalon is a chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM) noted for its resistance to chemicals, temperature extremes, and ultraviolet light.It was a product of DuPont Performance Elastomers, a subsidiary of DuPont. Hypalon as it is now known in the marine industry today is a remarketed version of the old Hypalon using an additional layer of …
