What is Universal Plastics

Universal Plastics refer to plastics with large output, low price and wide range of applications. They mainly include five major varieties: polyolefin, polyvinyl chloride, polystyrene, phenolic plastics and amino plastics.

These universal purpose plastics are used in a wide range of applications in our daily lives, e.g.

Polyethylene is used to make plastic bags, plastic boxes, etc.;

Polypropylene is used to make food packaging boxes, plastic cups, etc.;

PVC is used to make plastic pipes, plastic plates, etc.;

Polystyrene is used to make plastic toys, plastic furniture, etc.;

ABS is used to make plastic parts, plastic furniture, etc.

Universal plastic materials

Here are some common plastic material names and their properties commonly used in the injection molding process:

Polyethylene (PE)

Polyethylene is the most produced variety in the plastics industry. Polyethylene is an opaque or translucent, lightweight crystalline plastic with excellent low temperature resistance (the lowest operating temperature can reach -70 ~ -100℃), good electrical insulation, chemical stability, acid, alkali and Erosion from salt aqueous solutions. Polyethylene is suitable for processing by injection molding, blow molding, extrusion and other methods.

Polypropylene (PP)

Polypropylene is a thermoplastic obtained by polymerizing propylene. It is usually a colorless, translucent solid, odorless and non-toxic. It has a density of 0.90 ~ 0.919 g/cm and is the lightest universal-purpose plastic. Its outstanding advantages are its

Polyvinyl chloride (PVC)

Polyvinyl chloride is a plastic polymerized from vinyl chloride. It is bright-colored, corrosion-resistant, strong and durable. Its hardness can be greatly changed by adding plasticizers. The production methods of polyvinyl chloride include suspension polymerization, emulsion polymerization and bulk polymerization, with suspension polymerization being the main method. Since some toxic auxiliary materials such as plasticizers and anti-aging agents are added during the manufacturing process, their products generally do not store food and medicine.

Polystyrene (PS)

Universal-purpose polystyrene is a polymer of styrene, which is easy to color and has good transparency, but has the disadvantage of being brittle. Therefore, impact-resistant polystyrene (HTPS) can be made by adding polybutadiene. It is resistant to acid and alkali corrosion, but is easily soluble in organic solvents such as chloroform, dichlorethylene, banana water, etc.

ABS

ABS resin is a copolymer of three monomers: acrylonitrile-butadiene-styrene. It has the characteristics of hard, brittle, brittle, low impact strength and poor weather resistance.

Ten advantages of universal plastics

1. Easy to form and high degree of design freedom

Universal-purpose plastics have good formability and high design freedom, and can be molded through various methods such as injection molding, extrusion, and blow molding.

2. Easy to color

Universal plastics can be colored by dyeing and electroplating.

3. The specific strength is greater than that of metal

The specific strength of universal-purpose plastics is greater than that of metals, which means that under the same quality, universal-purpose plastics are stronger.

4. Lighter specific gravity

The lighter specific gravity of universal-purpose plastics gives them a competitive advantage in some application scenarios that require lightweighting.

5. Easy to modify and obtain required properties

Universal plastics have good modification properties and can be used to expand their scope of use through chemical and physical modification methods such as copolymerization modification, cross-linking modification, and graft modification.

6. Good electrical insulation

Universal plastics have good electrical insulation properties, which makes them widely used in electronic and electrical fields.

7. Good water resistance and no rust

Universal-purpose plastics have good water resistance and do not rust, which makes them advantageous in some application scenarios that require water resistance.

8. Good chemical resistance

Universal plastics have good resistance to many chemicals, such as acids, alkalis, etc.

9. Production consumes less energy than metal

universal purpose plastics consume less energy in their production compared to metals.

10. Proper processing of waste plastics will cause less damage and pollution to the environment than other materials.

Universal plastics proper handling of waste plastics can reduce environmental damage and pollution.

It should be noted that although universal-purpose plastics have many advantages, they also have some disadvantages, such as poor weather resistance, easy generation of static electricity, large thermal expansion coefficient, low surface hardness, etc.
