Problems solved by technology

[0002] As one of the most widely used materials, plastic is essential in daily life. Its plasticity, stability and economical practicability can bring convenience to people. Foam plastic is obtained by foam molding of plastic. Foam molding is The process of making plastics produce microporous structures. Almost all thermosetting and thermoplastic plastics can be made into foamed plastics. The products are convenient for storage and transportation, and have a wide range of applications. They can not only be used for agricultural mulch and packaging bags, but also widely used in the field of medicine. Foamed plastics have been fully integrated into people's lives, but there are also many problems caused by foamed plastics. The existing foamed plastics are not tough enough to support objects well, and the temperature resistance effect is not very good. Fires often caused by plastics have caused a lot of losses, so there is an urgent need for a heat-resistant and high-toughness polystyrene resin foam to change the current situation and bring more convenience to people
