S-Plastics Xenoy resin is a thermoplastic alloy blend of polycarbonate (PC) and polybutylene terephthalate (PBT). Amorphous polycarbonate has impact resistance and toughness, while PBT polymer has enhanced chemical resistance and thermal stability. Xenoy resin has the following characteristics: ductility, chemical resistance, high temperature dimensional stability and mechanical strength. This series of resins also have excellent aesthetic feeling, lubricity, UV stability and color retention. Xenoy resin was originally developed for the automotive industry. It has gasoline and raw oil resistance and high impact strength at low temperature [as low as - 40 ° f (- 40 ° C)]. The impact resistance improvement improves the balance performance of Xenoy resin, which has high and low temperature durability. Wh it is the combination of impact strength, chemical resistance and dimensional stability, or lubricity, high temperature resistance and toughness, Xenoy resin has a unique performance balance in engineering thermoplastic materials.
PC / PBT Alloy is the most common polyester alloy material. This alloy material not only retains the processing fluidity and solvent resistance of PBT, but also has the high dimensional accuracy and toughness of PC. It is widely used in the fields of electronic connectors and automobile exterior parts. The properties of PC / PBT Alloy materials are related to the structure, specifically, to the compatibility of the two and the crystallinity of PBT, which is directly determined by the transesterification of the two.
S-Plastics Xenoy 5220U is an unreinforced PBT+PC alloy. Improved retention of mechanical properties under UV. Excellent low temperature/chemical resistance.
