Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation. Alternative Names: Methoxy poly(ethylene oxide)-2-(dodecylthiocarbonothioylthio)-2-methylpropionate, PEG DDMAT macroCTA. Mole weight: average Mn 1,100.

Made from 2.2LB density polyethylene foam, this solution offers durability that is never too heavy or weighed down which makes it ideal for a wide range of applications. Closed-cell polyethylene cylinders come in a range of diameters and lengths widely used in masonry and concrete work as a backer rod to fill gaps between slabs before applying filler, saving time and materials. It can also be used in crafts or as padding or cushioning for unique projects. Being smooth, closed-cell foam, it is resistant to moisture. The small diameter of this tubing allows us to spool it for a continuous length, making it excellent for larger projects where consistency is important.
PET is a general-purpose thermoplastic polymer that belongs to the polyester family of polymers. Known for their excellent combination of properties such as mechanical, thermal, chemical resistance as well as dimensional stability, polyester resins are suitable for extruded applications that require clarity, toughness and consistent processing performance. PET can be alloyed and compounded with engineering resins. Polyester resins are low cost, withstand temperatures up to 80?C, offer good wetting to glass fibers, have a relatively low shrinkage of 4% ? 8% during curing, and provide a linear expansion ranging from 100 - 200 x 10-6 K-1. Alternative Names: PET. CAS No. 25038-59-9. Molecular formula: C10H12O6. Mole weight: 228.2g/mol. IUPAC Name: poly(ethylene terephthalate). SMILES: OCCO.OC(=O)c1ccc(cc1)C(O)=O.
