WebPolyisobutylene (PIB) Polyisobutylene (PIB) is a very versatile, non-toxic, water-white viscous liquid and has the ability to increase tackiness, to provide water-repellency, to improve viscosity-index and it provides excellent electrical insulation. Product is also known as Polybutene (PB), and is available in various molecular weights and in ... WebPoly(ethylene adipate) or PEA is an aliphatic polyester. It is most commonly synthesized from a polycondensation reaction between ethylene glycol and adipic acid. PEA has been studied as it is biodegradable through a variety of mechanisms and also fairly inexpensive compared to other polymers. Its lower molecular weight compared to many polymers …
