The characteristics of plastic and its application in toys


Plastic has penetrated into all aspects of our lives. Without plastic, our modern civilization will no longer exist. More and more plastics are not properly disposed of, causing many environmental problems. But apart from practitioners, the vast majority of the public knows little about plastics. Today I will introduce some basic knowledge about plastics.


The Characteristics Of Plastic And Its Application In Toys


1.How many kinds of plastics are there?

There is no precise number for the types of plastics, there are several thousand in theory. Moreover, scientists and the R&D departments of chemical companies are constantly inventing new varieties of plastics. The national standard "GB/T 16288-2008 Marking of Plastic Products" lists 140 kinds of plastics, covering most of the plastics currently used on a large scale. The common plastics in our daily life are the following: PET, PE (including HDPE and LDPE), PP, PS, PVC, PC, ABS, EVA, EPS, etc., in addition to the chemical fibers commonly used in the clothing industry (nylon, Polyester) and so on.


The body of most beverage bottles is PET; plastic bags are mostly PE; express lunch boxes are mostly PP, and some are PVC; toiletries bottles are both PET and HDPE; CDs are PC Material.

2.Properties of plastics

Most plastics are light, chemically stable, and will not rust;good impact resistance;has good transparency and abrasion resistance;good insulation and low thermal conductivity.

Generally, it has good formability and colorability, and low cost.Most plastics have poor heat resistance, high thermal expansion rate, and are easy to burn.Poor dimensional stability and easy to deform.Most plastics have low-temperature resistance, become brittle at low temperatures, and are easy to burn in.Some plastics are easily soluble in solvents.


Plastics can be divided into two types: thermosetting and thermoplastic. The former cannot be reshaped and used, and the latter can be reproduced. Thermoplasticity has a relatively large physical elongation, generally between 50% and 500%. The force does not completely change linearly under different elongation rates.


The different properties of plastics determine its use in life and industry. With the advancement of technology, research on plastic modification has not stopped. It is hoped that in the near future, modified plastics can have a wider range of applications, and can even replace steel and other materials and no longer pollute the environment.


3.Advantages of plastic toys

The Characteristics Of Plastic And Its Application In Toys


The following are our most popular plastic children toys:

Trampoline paddle ball set

Handheld pinball game

Basket case headband hoop game

Football Small Goal Post

Childs hockey set

Kid connection basketball set


The application of plastic in children's toys. Plastic material has strong plasticity, can adapt to a variety of design requirements and can be shared with other materials to enhance the design effect. Conclusion The material selection and use of plastic materials used in the design of children's intellectual toys have carried out beneficial design practices. The reasonable use of the plastic material's sensory characteristics makes the design effect of the toy have a good display.

1. Most plastics have strong corrosion resistance and do not react with acids and alkalis.

2. The cost of plastic manufacturing is low.

3. Durable, waterproof, lightweight.

4. It is easy to be molded into different shapes.

5. It is a good insulator.

6. Plastic can be used to prepare fuel oil and fuel gas, which can reduce crude oil consumption.
