Definition Halobutyl is a variety of synthetic rubber or elastomer and refers to halogenated butyl. The halobutyl rubber is the copolymer of isobutylene (98%) and a small amount of isoprene (2%). The abbreviation IIR is commonly used to describe butyl or halobutyl rubber as it stands for Isobutylene Isoprene rubber. The halobuty rubber is odorless and tasteless, though it may […]

 Definition EPT stands for Ethylene Propylene diene Terpolymer. ETP is the co-polymer of ethylene, propylene and diene EPT is also called EPDM by reference to Ethylene Propylene Diene Monomer Comment The primary synthetic rubbers include nitrile, isoprene, styrene-butadiene, butyl, chloroprene, polysulfide, silicone, urethane and ethylene propylene diene terpolymer (ETP) or Ethylene Propylene Diene Monomer (EPDM) The synthetics […]
