IGEABOND (Sumitomo Chemical)

It is an ethylene copolymer that was developed by SUMITOMO CHEMICAL CO., LTD. And has an epoxy group which is the only reactant in the molecule.

IGETABOND has the following key features

  -   High reactivity of epoxy group
  -   Extremely low glass transition temperature
  -   High processability

IGETABOND has been used to develop a variety of new Engineering Thermoplastics(hereinafter ETPs) and their alloys as a toughener and/or a compatibilizer. There are several grades of IGETABOND to meet a wide range of performance reqoirements.

GRADE

IGETABOND is a series of ethylene copolymers and terpolymers with glycidyl methacrylate(hereinafter GMA) as reactive sites.
