Why the transparent parts in plastic toys will be more brittle?
Transparent toy plastic
1, AS is a copolymer of acrylonitrile (A) and styrene (S). It is medium weather resistant and free from high humidity. It is resistant to general grease, detergents and mild alcohol. Suitable for plastic products: tray, cup, tableware, toothbrush, refrigerator, cell phone, knob, lighting accessories, accessories, instrument mirror, packing box, stationery.
2, polystyrene (PS) plastic is a relatively old plastic, the production process has been more perfect.Compared with other plastics, PS has a good transparency (transmittance 88% -92 (PS: its main drawback is: brittle, low impact strength, easy to appear, and easy to dye, high hardness, good rigidity, in addition, good water resistance, chemical corrosion resistance and processing flow properties. Stress cracking, poor heat resistance, etc.)
Plastic toys commonly used materials are the following: AB material (ABS resin) the original package material prices higher environmental color adjustable color is more bright and more bright and hard and brittle to change the material (mainly PEVA, PET) mixture color adjustable color worse Soft PP (PP) Mixer Color Adjustable Luster Poor Soft PVC (PVC) Black More Toy wheels Tire Soft Formaldehyde (POM polyoxymethylene resin) Hard Used in toys Internal cone
