How plastics are classified first depends on their appearance. ABS has an ivory white color, which is beige in color and has a good surface gloss. PP has a transparent milky white color with a slight waxy texture. PA has a slightly yellow or milky white semi transparent color. PET is a transparent material with high transparency. You can basically judge these materials from their appearance. Next, using the density method, four types are placed in water. PP floats on the surface with a density of only 0.91, PET sinks below with a density of 1.3, and ABS and PA are in the middle. Then, using the combustion method, ABS burns with black smoke and PA burns with blue smoke

ABS plastic infrared penetration ABS plastic is currently very popular in various fields, and its application areas are also very extensive. Let's take a look together. Because infrared radiation penetrates ABS plastic, it has outstanding characteristics such as high strength, low friction coefficient, oil resistance, and lightweight. This also allows them to have significant advantages over many metal materials in the use of automotive materials

Transparent nylon is a highly transparent nylon material that can be processed using thermoplastic methods and has various excellent properties. It is also an amorphous crystalline polymer with a special structure. Its molecular chain usually contains side groups or ring structures, which disrupt the regularity of the molecular chain, meaning it will not crystallize or micro crystallize, thus achieving good transparency. Transparent nylon has high light transmittance, similar to optical glass, high barrier properties, and excellent cooking resistance

ABS plastic and PS plastic: Which is better, ABS plastic or PS plastic? Answer: Generally speaking, ABS plastic has better performance than PS plastic. Products that can be made with PS plastic can generally be produced with ABS plastic, while products that can be made with ABS raw materials may not necessarily be produced with PS raw materials. If you want to compare, you have to set a premise, because ABS plastic contains flame-retardant ABS, weather resistant ABS plastic, and so on

Flame retardant/fire-resistant plastic materials are widely used in electrical appliances. At present, the popularity of household appliances has significantly increased, and industry competition has become more intense. Safety issues are also receiving increasing attention. In order to make electrical appliances difficult to ignite or self extinguish when exposed to fire, more and more flame retardants are added to plastic pellets, with the most widely used being flame-retardant ABS and flame-retardant PC/ABS. What is the difference between flame-retardant ABS and flame-retardant PC/ABS modified plastics

The structural characteristics and physical state of polymer materials themselves, as well as the external factors such as heat, light, thermal oxygen, ozone, water, acid, alkali, bacteria, and enzymes that they are subjected to during use, can cause performance degradation or loss during application, such as yellowing, relative molecular weight reduction, surface cracking of products, loss of luster, and more seriously, significant decrease in mechanical properties such as impact strength, tensile strength, and elongation
