LMW PPO Boosts Temperature Resistance of Hot Melts
GE Plastics has announced an exceptionally low-molecular-weight (LMW) version of one of its core polymers — polyphenylene oxide, or PPO® resin.
The new version of PPO resin developed by GE Plastics, called PPO SA120 resin, has a molecular weight of less than 2,500, which is nearly 90-percent lower than a typical PPO resin. Typical high-molecular-weight PPO resin, also known generically as polyphenylene ether (PPE), has been traditionally used in engineering thermoplastic blends from GE in products such as NORYL® resin and NORYL GTX® resin.
