PP plastic filler talcum powder proportional effect

Superior properties of stone powder fillerInorganic filler plays an important role in plastic modification and becomes an indispensable modification additive. In different application fields, talcum powder, as an extender, reinforcing agent, and functional modifier, has been recognized by the industry. This is inseparable from the properties of talc itself:

The connection force between the layers is very weak, which makes it soft and reduces the wear and tear of the equipment during processing; The lamellar structure can give the best balance between the stiffness and impact strength of the filling system. It has a certain affinity for organic matter; The talc surface is both hydrophobic and inert; Higher whiteness. However, the poor compatibility between the filler and the plastic matrix affects the final performance of the system, and the talc surface must be modified in order to improve the organic interface between the two.

Compared with other general-purpose thermoplastics, PP talcum powder has the advantages of small relative density, low quality, good processability and good comprehensive properties. Because it can be well compounded with a variety of materials, it can simulate the performance of engineering resins with low performance, and can be thinner and reduce weight, which makes it advantageous to meet the demanding requirements of automotive and electrical plastics in automotive and electrical material applications.

Poly Sailon engineering plastics, PP has the shortcomings of low temperature brittleness, low low temperature impact strength, poor rigidity, large molding shrinkage, and easy aging. PP plus talcum powder can increase the heat deflection temperature of filled PP plastic, increase the dimensional stability of the product, reduce the molding shrinkage rate, and improve the rigidity. The addition of ultrafine talc masterbatch, as a reinforcing filler for polypropylene, can not only significantly improve the rigidity, surface hardness, creep resistance and electrical insulation of polypropylene products, but also improve the impact strength of polypropylene, improve the impact resistance of PP, and endow the system with excellent surface properties. Talc also acts as a melt flow enhancer, as well as a synergistic agent with certain flame retardants.

Talcum powder is mainly used to improve the filling of the application point of plastic demand

1. Automobile interior parts: low odor, scratch resistance, high rigidity and other requirements.

2. Automobile exterior parts: they need to have high fluidity, rigidity, toughness, heat resistance, etc., as well as good dimensional stability and anti-aging performance.

3. Household appliances: The application requirements of household appliances are high fluidity, high toughness, medium and high modulus, high elongation at break, low shrinkage ratio, etc.

Hello, wait a minute, I have received your question, I will reply to you immediately.

The ratio of rubber talcum powder is generally 1 ratio, and talcum powder (calcium carbonate) is the industry standard of 900 mesh droplets. The ratio of PVC and talc powder used in the extrusion grade is 1 ratio, and the mesh number of talc rental powder is more than 1000 to ensure the quality of the product.

Polycylong engineering plastics, PP has the shortcomings of low temperature brittleness, low low temperature impact strength, poor rigidity, large molding shrinkage, and easy aging. PP plus slip to prepare stone powder can increase the heat deflection temperature of filled PP plastic, increase the dimensional stability of the product, reduce the molding shrinkage, and improve the rigidity; The addition of ultra-fine talc mother cover sensitive material, as a reinforcing filler of polypropylene, can not only significantly improve the rigidity, surface hardness, creep resistance and electrical insulation of polypropylene products, but also improve the impact strength of polypropylene, improve the impact resistance of PP, and endow the system with excellent surface properties. Talc also acts as a melt flow enhancer, as well as a synergistic agent with certain flame retardants.

Summary. The talc powder has the characteristics of sheet structure of thin sheet configuration, so talc with fine particle size can be used as a reinforcing filler for polypropylene. In the modified system of polypropylene, the addition of ultrafine talc powder can not only significantly improve the rigidity, surface hardness, heat creep resistance, electrical insulation, and dimensional stability of polypropylene products, but also improve the impact strength of polypropylene.

Adding a small amount of talcum powder to polypropylene can also play the role of nucleating agent, improve the crystallinity of polypropylene, so as to improve the mechanical properties of polypropylene, and improve the transparency of polypropylene due to improving crystallinity and refining grains. Polypropylene composites filled with 20% and 40% ultrafine talc can significantly improve the stiffness and creep resistance of polypropylene at both room and high temperatures.

Can you add talcum masterbatch directly to PP material for injection molding?

Yes, kiss <>

<> then add how much you can do the product will not sink.

Don't have specific numbers.

PP recycled material is generally added with 20-30% talcum powder, and the maximum can not exceed 40%.

The maximum amount of PP raw material added will not sink.

10 percent 25

Is it possible to add talcum powder directly to PP for injection molding, or to add talcum powder masterbatch.

Just add it and you're good to go.

Talcum powder. Can it be well compatible?

Yes, it's more compatible.

Is talcum powder added to PP plastic in line with food hygiene? What is the maximum percentage to add?

PP recycled material is generally added with 20-30% talcum powder, and the maximum can not exceed 40%. Polypropylene English name: polypropylene, abbreviation:

PP, commonly known as: 100-fold glue. PP plus talcum powder can improve the physical knowledge heat deflection temperature of PP plastic, increase the dimensional stability of the product, reduce the molding shrinkage rate and improve the rigidity.

The addition of ultra-fine talc masterbatch, as a reinforcing filler of polypropylene, can not only significantly improve the rigidity, surface hardness, creep resistance and electrical insulation of polypropylene products, but also improve the impact strength of polypropylene and improve the impact resistance of PP.

Summary. Pro, adding different proportions of talcum powder will have different effects on the physical properties of polyethylene materials, and the addition ratio is 10-15% to achieve the best. For polyethylene blow film, the filled ultra-fine talc masterbatch is better than other fillers, easy to form, and has good manufacturability.

Is talcum powder added to PP plastic in line with food hygiene? What is the maximum percentage to add?

Pro, adding different proportions of talcum powder will have different effects on the macro-fibrous properties of polyethylene materials, and the addition ratio is 10-15% to achieve the best. For polyethylene blow molding film, the loose filling ultra-fine talc masterbatch is better than other filling imitation pants material, easy to form, and has good manufacturability.
