How to enhance the heat resistance of plastic pallets in high temperature environments

The molecular structure of thermoplastics is a linear structure, which softens or melts when heated, can be molded into a certain shape, and becomes hard after cooling. After being heated to a certain extent, it softens again, and then becomes hard after cooling. This process can be repeated many times. Such as polyvinyl chloride, polyethylene, polystyrene, etc. The molding process of thermoplastics is relatively simple, can be produced continuously, and has relatively high mechanical strength, so it develops rapidly. The molecular structure of thermosetting plastics is a body structure, which also softens when heated, and can be molded into a certain shape, but after heating to a certain degree or adding a small amount of curing agent, it will be hardened and set, and it will not become soft or change after heating. Shape. After being processed and formed, thermosetting plastics will no longer be softened by heat, so they cannot be recycled and reused. For example, phenolic plastics, amino plastics, and epoxy resins are all such plastics. The molding process of thermosetting plastics is more complicated, so continuous production has certain difficulties, but its heat resistance is good, it is not easy to deform, and the price is relatively low.
