LEMALLOY is a brand name of our modified polyphenylene ether resin (m-PPE resin) polymer-alloy type products (island-sea structure), consisting of polyphenylene ether (PPE) as the island and crystalline resins such like polyamides (PA) and polypropylene (PP) as the sea. LEMALLOY therefore provides well-balanced properties of crystalline resin (chemical resistance and moldability) and PPE resin (dimension stability and high-temperature rigidity), enabling use under various environments.
