Network optimization data:

Look from plastic appearance, can distinguish plastic products to belong to thermoplastic, thermosetting or elastomer kind preliminarily. There are two types of common thermoplastics: crystalline and amorphous. Crystal plastic appearance for translucent, opacified or opaque, only in the film state was transparent, hardness from soft to hard, no keratin. No shape is generally colorless, no additives for all transparent, hardness from hard to gelatinous (often plasticizer and other additives to join) from horny to hard. Thermosetting plastics usually contain fillers and are opaque, or transparent without fillers. Elastic body feel is rubber, biodegradable plastic raw material has a certain scalability.

Decomposable plastics

Fever identification:

The heating properties of plastics are also different and can be identified by the method of heating. Hot plastics soften when heated, easy to melt, become transparent after melting, often can be extracted from the melt wire, generally easy to heat. Thermosetting plastic before heating to material decomposition, maintain the original hardness is not soft, the size is relatively stable, to decomposition temperature carbonization. Before the temperature of chemical decomposition, the elastomer will not flow when heated, and the biodegradable material will not be carbonized until the temperature of decomposition.
