Pelletized material

10. Pelletized material – A granular plastic material produced by a plastic material through a pelletizing device. With different granulation devices, the granule shape is also different, mainly hemispherical, cylindrical, square and so on. 11. Leftovers – all materials other than products in plastic molding operations. For example, burrs, main runner debris, shunt runner debris, overflow, parison residual material, waste products, etc.

Thermoplastic scraps can be recycled, while thermoset scraps cannot be reused.

12. Recycled material (recycled material) – also called crushed recycled material. It is a waste material such as runner material,  Plastic Screen Changer OME  gate material, flash material and unqualified products produced in injection molding, blow molding and extrusion molding. 13. Spring material – a common name for thermoplastic elastomers in the recycled material industry, the function is to increase the toughness of the recycled material. In some places, it is also called “ground jumping”.

14. Dead material – material that does not plasticize when heated. Generally refers to cross-linked thermoplastics. It is also called “raw material” in some places. 15. Melt Index (MI)—The mass value of the thermoplastic resin through a standard capillary tube in 10 minutes under a certain temperature and load, expressed in grams per 10 minutes.

It is a measure of the fluidity of thermoplastic resins when they are melted. The larger the numerical value is, the better the fluidity during melting is, but the tensile strength and the like are lowered. 16. Sound material – generally refers to the miscellaneous materials with metal sound such as ABS and PS. 17. Baba material – refers to the waste containing more impurities that is cleaned up when the filter is replaced. 18. Bubble – Plastic pellets made by a plastic pelletizer. 19. First-grade material – the material obtained by crushing or granulating the nozzle material, machine head material, leftover material, etc. 20. Resin – usually has a softening or melting range when heated. When softened, it has a tendency to flow under the action of external force. It is a solid, semi-solid or pseudo-solid polymer at room temperature. Sometimes liquid polymers are also possible. In the plastics industry, broadly refers to any polymer that is a substrate for plastics.
