Talc Powder For Degradable Plastic

Introduction of talc powder for degradable plastic：

The rapid increase in demand for inexpensive materials has caused an increased consumption and production of polymers to hundreds of millions of tons per annum. A consequence of this trend is a heavy pollution of the environment by the accumulation of polymer waste therein. The largest contributor to this problem is the packaging industry, which primarily uses cheap petroleum-derived polyolefins to produce disposable packaging film.

The problem of high environmental pollution with plastics was acknowledged over 20 years ago and has been followed by attempts to reduce the use of plastics through recycling. However, Not all polymer plastics can be recycled. Hence, there has been a growing interest in biodegradable and biocompostable plastics derived from renewable material sources, which do not pollute the environment by virtue of partial or complete biotic degradation.

In recent years, biodegradable plastics have been the most popular. According to the source of raw materials, biodegradable plastics can be divided into petroleum-based and bio-based plastics. Petroleum-based degradable plastics mainly include: polybutylene succinate (PBS), polyadipate/butylene terephthalate (PBAT), polyglycolic acid (PGA), polycaprolactone (PCL), etc. ; Bio-based degradable plastics mainly include: polylactic acid (PLA), starch, cellulose, etc.

Non-metallic mineral powders such as talcum powder and calcium carbonate, low price, environmentally friendly, sufficient raw materials, high fineness, good whiteness, easy color matching, can improve the dimensional stability, temperature resistance, rigidity of plastic products, and improve plastics Processing performance, etc.

Product features:

The addition of talc powder for degradable plastics can increase the rigidity, heat distortion temperature, dimensional stability, surface hardness, etc.; at the same time, ultrafine talc powder can also be used as an inorganic nucleating agent for polylactic acid (PLA), adding an appropriate amount of super Fine talc powder can increase the crystallinity and crystallization rate of polylactic acid, and greatly improve its mechanical properties.

Futai Talc powder for degradable plastic has three functions in the modification of polylactic acid:

1.    Reduce cost: The preparation method of talc-filled polylactic acid composite material provides a heat-resistant polylactic acid composite material preparation technology and method with beautiful appearance, good rigidity, short product molding cycle, light weight and low price.

2.    Improve strength: the natural talc powder is melt blended, and the composite material is a completely biodegradable material; it has excellent mechanical properties, and the tensile strength can reach 50~70MPa.

3.    Improve heat resistance: Polylactic acid has better heat resistance due to its own crystallization and the promotion of crystallization of nucleating agent talc.

Main uses of Talc Powder For Degradable composite:

★ Petroleum-based degradable plastics mainly include: polybutylene succinate (PBS), polyadipate/butylene terephthalate (PBAT), polyglycolic acid (PGA), polycaprolactone (PCL), etc.

★ Bio-based degradable plastics mainly include: polylactic acid (PLA), starch, cellulose, etc.

General parameters of talc powder for degradable plastic：

We recommend our regular models FT2092, FT3092, FTJ1250, 9715, 9725 to the customers who use talc powder for plastic modification for plastic processing. For more info about the products, please feel free to contact our technician representatives.

We can also supply according to customized quality demand.

Some precautions for using talcum powder：

To achieve the best results, use good talc powder, pay attention to the following points:

1. Talc powder must be subjected to surface activation treatment. The surface activation treatment of talc powder is mainly to improve the compatibility between talc powder and plastic raw materials and increase the modification effect. Different surface treatment agents should be selected for different plastics, such as Maleic anhydride grafted polypropylene is a good way.

2. The dispersibility of talc in plastic raw materials. Under the same formula, the dispersibility of talc in plastic raw materials has a great influence on the final physical and chemical properties of the modified material. It should be strictly controlled in the production process to affect the dispersibility of talc in plastics. The main factors of dispersibility in raw materials are formula, temperature, output, technological process, etc. In addition, when the amount of talc added is large, a step-by-step method can be adopted to achieve a good dispersion effect.

3. For different plastics, different specifications of talc should be selected to achieve the desired effect. This is very particular, and a bad choice may backfire. Because different plastics, different products, and different conditions of use have different requirements on raw materials, different choices must be made to achieve the desired effect.
