Description
Nano TiO2 powder for plastics
Introduction:
The nano TiO2 powder is a white fluffy powder with a small particle size and uniform particle size. Nano-sized silicon aluminum composite dense inorganic coating is adopted. After special organic treatment, a dense silicone and titanate film is formed on the surface of the powder, which improves the dispersibility of the powder and avoids the secondary agglomeration of the powder. The treated nano-titanium dioxide powders can be crosslinked with the resin to enhance the adhesion between the resin and the powders. It can obviously improve the aging resistance and mechanical properties of plastics, and has strong antibacterial effect..

Nano TiO2 powder for plastics
Application characteristics:
The addition of rutile nano titanium dioxide (T03) in plastics not only has the properties of white pigment but also can improve the heat resistance, light resistance and weather ability of plastics. The physical and chemical properties of plastics can be improved obviously, the mechanical strength of plastics can be enhanced and the service life can be prolonged. Wanjing nano titanium dioxide (special for plastics) has the following advantages over ordinary titanium dioxide in plastics applications:
- The rutile-type nano-titanium dioxide (T03) has good absorption performance to ultraviolet UVA and UVB, can effectively absorb ultraviolet light, prevent plastic from damage by sunlight, help prevent plastic products from cracking, fading and other light degradation. The performance of this product is more than three times higher than that of ordinary titanium dioxide.
2, the strength, toughness, aging resistance, heat resistance and impact resistance of plastics are increased by several times.
3, the UV shielding, antistatic and tensile properties of plastics have been significantly improved.
- The surface of Wan Jing nano titanium dioxide (TA03) film has a high degree of self-cleaning effect.
- nano titanium dioxide (TA03) has obvious bactericidal, bacteriostatic and antibacterial effects on harmful bacteria.
- Adding nanometer titanium dioxide (TA03) to plastic products can accelerate the degradation rate of plastic products.
Application:
- Used as a light stabilizer for sunscreen plastics, including sports goods, outdoor facilities, fabrics and carpets.
- Antibacterial plastics: used for children’s toys, food preservative film, packaging bags, electrical appliances, furniture, tableware, public facilities, etc.
- degradable plastics: widely used in disposable films, disposable lunch boxes, agricultural films, plastic bags, etc.
Addition: 1-5% is recommended. Users can determine the optimum addition according to different systems through experiments.
Packing: 20 kg / barrel.
