ALBIFLEX 297

ALBIFLEX® 297 is a bisphenol-A-epoxy-silicone block copolymer resin which is used to manufacture high-performance elastomers. ALBIFLEX® 297 is liquid at ambient temperature, epoxy reactive and cures with all aliphatic and cycloaliphatic epoxy resin curing agents. It can be processed by all conventional casting or molding techniques. The specially designed block copolymer structure of ALBIFLEX® 297, made up of epoxy and silicone segments, provides an outstanding combination of properties: ▪ high thermal shock resistance and temperature stability ▪ a glass transition temperature that is less reduced compared to other plasticizers ▪ excellent elongation ▪ high mechanical stability ▪ good adhesion on most substrates ▪ high hydrolysis stability ▪ very low moisture absorption ▪ lower water vapour permeability than silicones.
