Polycarbonate (PC) is a kind of thermoplastic engineering plastics with excellent comprehensive properties. It has excellent electrical properties and good light transmittance, it is the only one with good transparency among the five general engineering plastics, its transmittance of visible light can reach more than 90%! At present, polycarbonate is widely used in electronic appliances, automotive components, medical equipment, sun shield sheet and packaging materials.
In the automobile industry, the automobile exterior decoration materials requires very high performance. Such as car lampshade, not only requires the material to have good transparency and scratch resistance, the substrate resin must also have excellent photo-aging resistance and anti-yellowing properties.
Polycarbonate has undoubtedly become the preferred resin for car lampshades, but if it is used outdoors for a long time, its weather resistance still cannot meet the requirements. When PC long-term exposures to UV light, it will turn yellow, even degradation and brittle. This is mainly because it will start photooxygen aging reaction, when PC materials are subjected to heat, oxygen and light at the same time.
So how to solve the problem of PC materials photo-aging?
OMNISTAB UV3030 is a high molecular weight UV absorber with excellent thermal stability and extremely low volatile. It is especially suitable for high transparency PC materials, which can effectively protect PC from photo-aging.
vKey benefits of OMNISTAB UV3030:
ØOMNISTAB UV3030 belongs to the Cyanoacrylate UV absorber, it can strongly absorb the UV light between 280-320nm. Its macromolecular structure gives it excellent thermal stability and low precipitation during processing.
ØHigh safety. OMNISTAB UV3030 is FDA approved for use in food contact materials.
ØBesides, UV3030 has good color stability for product. Therefore, it can be used for transparent polymers with high extrusion temperature, such as PC, PMMA extrusion molding and other processes.
ØOMNISTAB UV3030 is also used in coatings and adhesives, such as acrylic varnishes and vinyl adhesives.
vUV absorption spectrum of OMNISTAB UV3030:
TDS of OMNISTAB UV3030
vGuidelines for usage:
The recommended dosage of OMNISTAB UV3030 is about 0.3-2.0%, which depending on substrate and performance requirements of final application. When OMNISTAB UV3030 is used in combination with other functional additives (such as OMNISTAB antioxidants and HALS),your product will achieve better weather resistance and longer service life.
