描述
NORYL HM4025H Resin is a 40% glass fiber and mineral reinforced blend of polyphenylene ether (PPE) and high impact polystyrene (HIPS), manufactured by SABIC. This high flow, injection moldable grade contains non-brominated, non-chlorinated flame retardant and carries UL94 flame ratings of 5VB and V-1.
NORYL HM4025H Resin exhibits good dimensional stability, low warpage, and low moisture absorption. It offers hydrolytic stability, low creep sensitivity, good processability, and high stiffness/strength. The combination of these properties makes it an excellent candidate for printer chassis and other consumer electronic components. This product does not contain PFAS intentionally added during the manufacturing process.
