The material has been in short supply, so its price has risen. Asnylon 66 chip is one of the five major general-purpose engineering plastics, its market fluctuation has caused wide spread concernin the industry. China Engineering Plastics Association recently investigated this market fluctuation and analyzed its reasons in a report. 1. The economic growth pushed upnylon 66 chip展开更多
