SABIC introduces injection molding PBT for medical applications
SABIC introduces VALOX HX325HP resin, a new high-performance, medical-grade, injection molding polybutylene terephthalate (PBT) resin.
As a thermoplastic polyester solution, the new material is developed especially for high-precision parts, such as components of insulin delivery pens, insulin pumps, auto-injectors and continuous glucose monitors.

SABIC’s VALOX HX325HP resin is used to produce glucose applicator.
The new resin provides outstanding processability, demonstrating high flow even in complex designs, as well as excellent mold release properties with lower shrinkage variation compared with competitive engineering plastics.
In applications, VALOX HX325HP resin delivers high resistance to a wide range of chemicals for the mitigation of environmental stress cracking (ESC), as well as compatibility with ethylene oxide (EtO), gamma irradiation and steam sterilization.
It has also been successfully tested to international biocompatibility standards. Preliminary assessments according to ISO 10993 or USP Class VI are available upon request. In addition, the grade is subject to SABIC’s Healthcare Policy, providing reliable formulation lock and change control management in line with FDA and EU guidelines for medical-grade plastics.
VALOX HX325HP resin also serves as a formaldehyde-free alternative to polyoxymethylene (POM) materials. The resin is supplied as an unreinforced, neat material, as well as in a limited range of standard colors.
