The development of plastic foam materials and processing, as well as the new packaging design, have a tendency to promote "lightweight", and plastic foam is more conducive to the lightweight of plastic packaging. Now microwave ovens and microwave foods have entered people's home life, while plastic foamed food-molded food packaging containers have a heat resistance of up to 130 ° C (and foaming ps of only 80 ° C), can be used in microwave ovens, and resistant to boiling water, High temperature stability, comfortable and soft surface; its thermoformed plates, bowls, etc. have better performance than pe and ps at low temperature, so it has obvious advantages for disposable packaging.
Light weight, one-time packaging has obvious advantages
The addition of plastic foam to the filler can reduce the cost, reduce the exothermic peak intensity and shrinkage of the curing, improve the apparent quality, and improve the chemical resistance. Commonly used are talc powder, quartz powder, hollow microspheres and the like. However, talc and quartz powder increase the density of the foam and lower the mechanical properties. Hollow microspheres with low bulk density are an ideal filler. Divided into two categories of organic materials and inorganic materials. Plastic foam inorganic microspheres such as glass hollow microspheres, ceramic hollow microspheres; organic microspheres such as phenolic hollow microspheres, urea formaldehyde solid microspheres, expandable polystyrene particles. In general, inorganic microspheres are more effective as fillers for epoxy foam. It improves the strength, heat resistance, dimensional stability and surface smoothness of the foam. The microspheres float during the foaming and solidification process, so it is necessary to add an appropriate amount of thixotropic agent.
