To increase the heat resistant performance of plastic tray

by:Qusheng     2020-11-13
During the hot summer, the hot sun exposure can easily affect the service life of the plastic tray, so to increase the heat resistance of plastic tray?
thermoplastics are linear structure, molecular structure in soften or melt when heated, but with molding into a certain shape, after cooling and hardening. Are heated to a certain extent again softened, cooled and hardened, this process can be repeated several times. Such as PVC, polyethylene, polystyrene, etc. Thermoplastic plastic molding process is simpler, can continuous production, and has high mechanical strength, thus developing very quickly.
is the molecular structure of the thermosetting plastic shape structure, when heat softening occurs, can with molding into a certain shape, but after heated to a certain degree or to join a small amount of curing agent, hardening largely, reheat does not become soft change shape. Thermosetting plastic processing and forming, the heat is no longer to soften, therefore cannot be recycled, such as bakelite, amino plastics, such as epoxy resin belong to this kind of plastic. Thermosetting plastic molding process is complicated, so continuous production has the certain difficulty, but it has very good heat resistance, not easy to deformation, and the price is cheap.
