In modern society, people can not do without plastic. Whether it is used in everyday life plastic bags, plastic boxes appliance plastic products, or in computers, mobile phones, and also whether it is within reach of plastic tables and chairs around us plastic products processing, or deeply buried plastic pipes, plastic products and people's lives. Since the production of plastics processing using a large number of chemical raw materials and additives, in particular in contact with drinking water and food as the end-consumer plastic products, and its performance, quality and safety of a direct impact on the rights of consumers and even body health. Plastic products, quality and safety by the community concern. It is understood, now commonly used in the market toughening PBT EMA-GMA, EBA-GMA and POE-GMA. Ester base plastic molding on 1.EMA-GMA and EBA-GMA main chain, and POE-GMA molecular chains are unsaturated bonds, in theory, thermo-oxidative stability is better than saturated carbon chain unsaturated carbon chains, POE from the oxidation induction time and EMA raw materials also proved this point. For oxidation induction temperature test toughening product also showed, SOG-02 in the air (POE-GMA) has a better than EMA-GMA and EBA-GMA thermal oxidative stability. 2. From the main chain in terms of flexibility, POE-GMA> EBA-GMA> EMA-GMA. The glass transition temperature Tg lower plastic products, the better the molecular chain flexibility, toughness better. Therefore, only be considered in the molecular structure of Tg, POE PBT toughening the matrix should be a more appropriate choice of plastic products processing plastic products _ _ Lianjiang Industrial Rady Rady provided by the Dongguan City Industrial Co., Ltd.
