Plastic modifiers

Polyscope produces a wide range of XIRAN SMA copolymers that are used as modifier in thermoplastic polymers. Heat boosting, adhesion promotion, dispersion and compatibilization are the effects that can be achieved in thermoplastics and blends. The product is a proven additive in: ABS, PC, PET, PBT, PMMA, PA, HIPS, GPS, PVC, TPE. SMA is a unique polymer, were a-polar and polar monomers are polymerized into a copolymer chain. XIRAN SMA is available in a broad range of molecular weights and maleic anhydride (MA) contents. In a typical combination of those two properties SMA is available as a crystal clear granule that can be used in a broad range of applications. SMA can maintain transparency in combination with heat boosting effect in other transparent materials like PMMA or SAN.

SMA further improves the heat resistance of other polymers like ABS, PS, PVC. The specific reactivity of SMA makes it a suitable agent for compatibilizing normally incompatible polymers (e.g. ABS/PA, PC/ABS, PET/ABS blends). Another function of the SMA is to improve the adhesion with other chemicals or materials (foam, metal and paint). Typical dosing levels of SMA in polymers vary from 0,5 - 50 % and are depending on the needed application objectives.
