USP Class VI Adhesives
USP Class VI Approved Adhesives for Medical Device Applications
Master Bond’s biocompatible adhesives are designed to meet the needs of medical device manufacturers. Compounds withstand various types of sterilization methods.

SABIC NORYL™ Resin HN731A Polyphenylene Ether + PS (PPE+PS)
Categories: Polymer; Thermoplastic; Polystyrene (PS); Polystyrene + Polyphenylene Ether, Unreinforced
Material Notes: NORYL™ HN731A resin is a non-reinforced blend of polyphenylene ether (PPE) + high impact polystyrene (HIPS). This injection moldable grade is US FDA and European Food Contact approved, biocompatible (ISO10993 or USP Class VI), RoHS compliant, and It is subject to SABIC’s Healthcare management of change and formulation lock. NORYL HN731A resin exhibits good impact resistance, excellent hydrolytical stability, and chemical resistance. This light weight and colorable material is an excellent candidate for medical device and pharmaceutical applications such as drug-delivery inhalers.

Features: Hydrolytic Stability,Low Creep Sensitivity,Steam Sterilizable,Radiation Sterilizable,Gamma Sterilizable,Ethylene Oxide Sterilizable,E-beam Sterilizable,Low Warpage,Food Contact Acceptable,Biocompatible
