Bentonite compound biodegradable starch particles

Bentonite compound starch biodegradable material mainly consists of the following applications effects:

1, this modified method to achieve a starch, PVA plastics can melt processed under any condition.

2, to improve the processing, flowability and transparency. Can blow molding, injection molding, sheet extrusion, foam, etc.,

3, to overcome the starch reversibility and recrystallization phenomenon, expanding the application fields.

4, excellent physical properties at or near some plastic properties, 100% tensile strength 15-20Mpa starch plastics better than the prior art full-starch tensile strength 8-10Mpa.

5, fully biodegradable, the resulting H2O, CO2, abandoned after no pollution, is completely biodegradable plastic in the true sense.

6, simple easily understood realization process of production, large-scale production, low investment characteristics.

7, low cost of biodegradable plastics huge market space and improve competitiveness.

8, the added plasticizer, additives can be biodegradable and do not contain any harmful ingredients petroleum-based products, such as heavy metals.
