Plastic toys are a big category of toys. There are many raw materials of plastic toys, such as ABS, PVC, PP, PC, PE, EVA and PU.

1. ABS

ABS is the main material of splice blocks, three letters respectively represent "acrylonitrile, butadiene, styrene" three substances.

The main reason why ABS is used for splicing blocks is its good dimensional stability, and the basic particles made can keep the height of the same size. At the same time, ABS has high hardness and toughness, even at low temperature, it will not become brittle (low temperature resistance - 40°). Then, wear resistance.

In addition to splicing blocks, some models (such as Gundam, Transformers, plastic dolls, etc.), cars (inertial recovery vehicles, electric cars, riding children's vehicles), crawling plastic toys will use ABS, the purpose is to prevent damage.

It is said that the main material of CAT engineering car is not ordinary ABS, but engineering plastic ABS (this needs to be verified) :

2. PVC

PVC can be hard or soft. The hard water pipes as follows can be made of PVC, and the soft ones such as infusion pipes and slippers can be made of PVC. In terms of plastic toys, PVC is the most used material.

Most inflatable toys (with the exception of balls) are made of PVC, such as croissants, vaulting horses and balloons.

PVC is also the main material for soft and hard animal models (in the category of children's toys), such as the dinosaurs of Slough and PAPO:

Rigid PVC is relatively met a bit less on the application of toys. PVC toys can not be disinfected with boiling water, directly with toy cleaner disinfection is OK, or with a dishcloth dipped in soapy water to wipe can also.

3. PP

Compared with the above two materials, PP has the advantage that it can be put into the microwave. So often do containers, to hold food, oil, condiments, such as lunch boxes, crisper. After PC bottles were banned a few years ago, PP became the main material used in plastic bottles.

In toys, PP materials are mainly used in tooth glue, rattle these small toys, one can be imported, two can be boiled at high temperature disinfection.

4. PC

Pc-based baby bottles were popular until 2011, but are now banned. The reason for the ban is that PC materials contain bisphenol A (BPA), which is believed by the European Union to cause premature puberty and endocrine disorders, threatening the health of fetuses and children.

In the same way, PC-based toys can contain BPA, and there are similar, but cheaper, toys on the market.

5. PE

Soft PE is mainly used in film products, such as food cling film, plastic bags; Hard characteristics suitable for injection molding products and hollow products.
