TPU recycled materials(TPU再生材料)

TPU recycled materials refer to waste TPU raw materials (including blends, miscellaneous materials, etc.) that are recycled and decomposed as raw materials.


1. Recycled materials-scraps or waste plastics from other sources in the plastic molding process, which can be reused to make lower-quality products after proper treatment.

2. Recycled plastics-plastics based on recycled materials.

3. Nozzle material-refers to the waste material formed by the runners, corners and unqualified products produced in the production process of injection molded products.

4. Die head material-refers to the leakage material or transition material in the production process of extruded products and the cleaning material when the injection molding machine is empty.

5. Sub-brand material-part of the unqualified plastic material produced by changing the brand or variety during the synthesis process of the plastic material

6. Submerged material-refers to materials with a specific gravity of more than 1 g/cm3.
This specifically refers to plastic materials containing mineral fillers (polyolefin-based fillers).

7. Floating material-refers to materials with a specific gravity of less than 1 g/cm3.
This specifically refers to plastic materials (polyolefins) that do not contain mineral filling. 8. Flower material-refers to multi-color miscellaneous materials.

9. Grinding material-the powdery material obtained by pulverizing plastic waste through a plastic pulverizer.

10. Pelletizing material-the granular plastic material produced by the plastic material through the granulating device.
With the different granulation device, the granule shape is different, mainly hemispherical, cylindrical, square and so on.

11. Leftovers-all materials other than products in plastic molding processing operations.
Such as burrs, sprue waste, shunt waste, overflow, parison remnants, waste products, etc.
Thermoplastic scraps can be recycled, while thermoset scraps cannot be reused.

12. Recycled materials (recycled materials)-also called crushed recycled materials.
It is waste materials such as runner materials, gate materials, flash materials and unqualified products produced in injection molding, blow molding and extrusion molding.

13. Spring material-the common name for thermoplastic elastomers in the recycled materials industry, whose function is to increase the toughness of recycled materials.
Some places are also called “dibeng”.

14. Dead material-material that does not plasticize after heating.
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 within 10 minutes under a certain temperature and load, expressed in grams/10 minutes.
It is a measure of the fluidity of the thermoplastic resin when it melts.
The larger the value, the better the fluidity during melting, but the tensile strength etc. decrease.

16. Noise material-generally refers to ABS, PS and other metal noise materials.

17. Baba material-refers to the waste material containing more impurities that is cleaned up when the filter is replaced.

18. Bubble material-plastic agglomerates made by a plastic agglomerator.

19. First grade material-material obtained by crushing or granulating nozzle material, head material, leftover material, etc.

20. Resin-usually has a softening or melting range when heated. When it is 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 it can also be a liquid polymer. In the plastics industry, it broadly refers to any polymer as a plastic substrate.
