BX IM 225 MBS Impact Modifier/toughener
Description
IM225 is using advanced synthetic resin technology carefully developed for PC and PC alloy and other engineering plastic compounding, a special toughening agent by our company, its core-shell structure is carefully designed by polymers, it can improve impact strength while not damaging other properties, such as thermal deformation temperature. It has no adverse effect on weather resistance. Compared with traditional MBS products, IM225 is better in impact resistance, chemical resistance, heat resistance, dispersity, compatibility and other aspects.
IM225 can be widely used as an MBS impact modifier for engineering plastics including PC, PC/ABS, PC/PBT, polyester(PET,PBT), styrene-acrylonitrile copolymer (SAN) and other alloy toughening systems.
BX IM 225 is Equal to Dow EXL-2620/2690, Kenaka M711/701/722/724, LG EM500, Arkema Clearstrength E920, Send an inquiry to check the comparison test.
