Detailed analysis:

The chemical name of acrylic is polymethyl methacrylate, which is an important plastic polymer material developed earlier. It has good transparency, chemical stability, weather resistance, easy dyeing, easy processing and aesthetics, and is widely used in the construction industry. Plexiglass products can usually be divided into pouring plate, extrusion plate and molding compound.

Freon board is a new type of chemical board. It is made of high-pressure polyethylene EVA as the main raw material and various additives. It is formed by chemical bridging and foaming. Referred to as EVA board, single-sided or double-sided composite PVC board, later called Floon board. Its surface is smooth and has a certain hardness.

Blister character is a plastic processing technology. The main principle is that the flat plastic hard sheet is softened by heating, then adsorbed on the surface of the mold by vacuum, and then formed after cooling. Widely used in plastic packaging, lighting, advertising, decoration and other industries.
