Specialized additives for high transmittance materials

Product brand

Highly transparent plastics such as PC, PET, PMMA, etc., are widely used in the fields of electrical and electronic appliances, automotive parts, medical devices, building sunshades and packaging materials due to their high strength and excellent dimensional stability.

These applications place increasingly high requests on the materials, which not only require good transparency and scratch resistance, but the resin must also have excellent resistance to light aging and anti-yellowing properties.

“OMNISTAB^® HT” series is especially suitable for highly transparent plastics, which can significantly improve the long-term UV aging and oxygen aging resistance of the material without affecting the color and transparency of material, which can improve the quality and long-term aesthetic of the highly transparent plastic products.

“OMNISTAB^® HT” series for high light transmission materials have the following advantages:

1) The product itself has low chromaticity and does not form complexes with metal ions, so it does not adversely affect the color of plastics. Even at a very high additive amount, it does not affect the color of the product, especially suitable for the natural color materials, transparent plates, film materials, etc., which have high requirement for color.

2) High temperature resistance, low volatility, excellent precipitation resistance.

3) Good compatibility with many solvents, besides high transparent plastics, it can also be applied in coatings to improve light resistance and color stability.

It is worth mentioning that our “Specialized additives for high transmittance materials” also has mature applications in the field of photovoltaic materials, as this series of products have low chromaticity, high transmittance in the visible light band, does not affect the color and transparency of photovoltaic adhesive, which will significantly reduce the loss of sunlight through the film, and avoid the decline in the amount of light, so as to enhance the overall efficiency of photovoltaic devices. This will greatly reduce the loss of sunlight through the film and avoid the decrease of radiant flux, thus improving the overall efficiency of PV devices.
