Corrugated Plastic Partitions can be divided into two types: thermosetting and thermoplastic. The former cannot be reshaped and used, and the latter can be repeatedly produced. Hollow boards are divided into general-purpose plastic hollow boards and engineering plastic hollow boards, which are mainly defined by the wide range of uses, such as PE hollow boards and PP hollow boards, which are relatively cheap. It can be produced on many different types of machines. Engineering plastic hollow board is more expensive, but the raw material stability and physical properties are much better, and it has both rigidity and toughness.

①Most plastic hollow boards are light in weight, chemically stable, and will not rust; ②Good impact resistance; ③Good transparency and wear resistance; ④Good insulation, low thermal conductivity; ⑤General formability, Good colorability and low processing cost; ⑥Most plastics have poor heat resistance, high thermal expansion rate, and easy to burn; ⑦Poor dimensional stability, easy to deform; ⑧Most plastics have poor low-temperature resistance and become brittle at low temperatures; ⑨easy to age; ⑩some Plastics are easily soluble in solvents.

Two different structures show two opposite properties. Linear structure (including branched-chain structure) polymers are elastic and plastic due to the existence of independent molecules that can be dissolved in solvents can be melted by heating, and have low hardness and brittleness. Because there are no independent macromolecules, the body structure polymer has no elasticity and plasticity, cannot dissolve and melt, can only swell, and has greater hardness and brittleness. Plastics have two types of macromolecules. Those made of linear polymers are thermoplastics, and those made of body-shaped polymers are thermosetting plastics.
