NORYL™ Resin HM4025H

NORYL HM4025H resin is a 40% glass and mineral reinforced blend of polyphenylene ether (PPE) + polystyrene (PS). This high flow, injection moldable grade contains non-brominated, non-chlorinated flame retardant and carries a UL94 flame ratings of 5VB and V1. NORYL HM4025H resin exhibits good dimensional stability, Low warpage, and low moisture absorption. It is an excellent candidate for printer chassis and other consumer electronic components.
