Plastic additives

Arkema is a major global player in the manufacture of additives for PVC, Engineering plastics, Bio-polymers and Thermosetting resins. From acrylic and methacrylate-butadiene-styrene (MBS) impact modifiers, to acrylic processing aids; our full range will overcome your expectations for the reinforcement and the processing of thermoplastics, and for the toughening and the process gain of thermosetting resins.

Impact modifiers

Logo Durastrength® - Logo Clearstrength®

Arkema’s acrylic and MBS impact modifiers improve the impact strength of thermoplastic materials, while offering an optimal cost-performance balance. These additives are particularly designed for the reinforcement of PVC articles for exterior applications, as PVC windows, but also interior applications as furniture films or transparent packaging. Modifer range was extended with toughening agents dedicated to the reinforcement of thermosetting resins which are employed in composites materials or in structural adhesives formulations.

Our additives solutions

Thermoplastic resins

Our impact modifiers and processing aids are used in a wide range of applications by enhancing performances of PVC, cPVC, engineering plastics such as polycarbonates, polyesters, polyamides including their blends, and biopolymers such as PLA, cellulose acetate, or PHA.

Thermosetting resins

Our toughening agents allow to increase toughening performances, by optimizing processing conditions, in a large spectra of matrices such as Methylmetacrylates, Epoxy, and Polyesters, mainly used in structural adhesives and high performance composites applications.
