Plastic Modification
Plastic modification is a relatively broad concept. Whether it is to improve the original properties of the resin through physical, chemical, mechanical or other means, it is called plastic modification. The application range of plastic modification is relatively wide. Definition It can be said that all plastics can be modified to improve their quality, such…

Blow Molding
Also known as hollow blow molding, it is a rapidly developing plastic processing method. Blow molding technology began to be used to produce low-density polyethylene bottles during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The…

Injection Molding
A plastic processing method in which the plastic is plasticized in the heated barrel of the injection molding machine and then injected into the cavity of a closed mold by a plunger or a reciprocating screw to form a product. This method can process products with complex shapes, precise dimensions or with inserts, and has…

High Density Polyethylene (HDPE)
High-density polyethylene (HDPE) is a white powder or granular product. It is non-toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and an operating temperature of up to 100°C; its hardness, tensile strength and creep are better than those of low-density polyethylene; it has good wear resistance, electrical…

Degradable Plastics
Degradable plastics refer to a type of plastic whose products have various properties that can meet the use requirements, and whose properties remain unchanged during the shelf life, and which can be degraded into environmentally friendly substances under natural environmental conditions after use. Therefore, they are also called environmentally degradable plastics. There are many new…

Polyethylene (PE)
Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene monomers. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low-temperature resistance (the lowest operating temperature can reach -100~-70°C). It has good chemical stability because the polymer molecules are…
