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.
