PHOTO NO.62359995

Polyester materials boast comprehensive advantages such as high strength, wear resistance, and easy processability, making them widely used in high-end cosmetic packaging bottles, textile fibers, automotive window films, automotive interior and exterior trim, polycarbonate optical components, and other fields. As the application scope continues to expand, the market demands higher performance: maintaining the mechanical properties of polyester materials, solving the aging and degradation problems caused by UV radiation, while preserving the product's initial color, light transmittance, and aesthetics.


To meet the market promotion and application needs of polyester materials, DELTACHEM introduces the "Super High-Temperature Resistant UV Absorber," Omnistab® UV6138. UV6138 is precisely tailored for polyester material application scenarios, achieving long-lasting UV protection!

 

Why is Omnistab ®UV6138 the preferred ultraviolet absorber for polyester materials?

ØWide-band UV absorption provides comprehensive protection for polyester

Omnistab ®UV6138 has a wide-band UV absorption effect, with strong absorption within the 260-400nm band range. This full-spectrum coverage feature acts like an "ultraviolet protective shield", offering a broader protection range and a more lasting protective effect than ordinary ultraviolet absorbers. It effectively prevents surface cracking, mechanical property degradation, and yellowing of materials due to ultraviolet radiation, significantly extending the product's service life.

The UV shielding effect of Omnistab UV6138 in PET

From the above spectrum, we can see that adding Omnistab ®UV6138 to PET can achieve 100% blocking of all ultraviolet light below 400nm, indicating that UV6138 achieves high-intensity absorption in the UVB and UVA bands. Meanwhile, 6138 has no absorption in the visible light part, perfectly meeting the strict requirements for visual transparency of high-end transparent polyester materials.

 

ØIt has excellent thermal stability and is suitable for high-temperature processing

The TGA (10%) of Omnistab ®UV6138 is above 370, with excellent thermal stability, making it suitable for high-temperature processing techniques. Moreover, Omnistab ®UV6138 has a high molecular weight, low volatility, and good migration resistance. It is not easily lost or precipitated during the high-temperature processing of polyester materials, and has a minimal impact on the molding effect and mechanical properties of polyester materials. It perfectly meets the processing requirements of thermoplastic polyester.

 

ØLow chromaticity, meeting the demand for high light transmittance

After addition, Omnistab ®UV6138 is colorless and stainless. It can retain the high light transmittance of optical components such as optical lenses and mobile phone protective screens, while effectively blocking ultraviolet rays, ensuring the long-term stable performance of the product.

 

Typical application fields of Omnistab ®UV6138

ØPolycarbonate automotive exterior trims, optical products (automotive headlights, optical lenses, protective screens, etc.)

ØPET bottles, films and fibers (food packaging, car window films, etc.)

ØHigh-end cosmetic packaging materials

ØHigh-performance engineering plastics and special plastics

 

In various scenarios, the Omnistab ®UV6138 consistently provides solid and reliable UV protection with its outstanding performance.
