JIANGSU CHEMK CO.,LTD (CHEMK) is a major UV absorber manufacturers in the Chinese market with the emphasis on developing high quality UV absorber products and HALS in China.

As a manufacturer with many years of experiences in UV absorbent production, our pursuit is to create the best quality products in the world through innovation, which is critical for the company. CHEMK will constantly bring innovation and change to life and develop new products and technologies in an environmentally friendly manner.

CHEMK BRINGS INNOVATIONS AND SUSTAINABLE DEVELOPMENT:

CHEMK offers three series UV absorber productions: UV-TRIAZINE SERIES, UV BENZOTRIZOLE SERIES and Hindered Amine Light Stabilizers (HALS).

UV BENZOTRIZOLE SERIES UV absorbers have a broad spectral coverage and are used for various applications such as plastic, textiles, coatings, adhesives and sealants. In the coatings area, the applications of BTZ (2-(2-hydroxyphenyl)-benzotriazoles) ranges from medium- (industrial/architectural) to high-end (automotive).

UV-TRIAZINE SERIES UV absorbers exhibit superior photo permanence and heat stability compared to BTZ and BP.  In addition, HPT (2-hydroxyphenyls-Triazines) shows excellent chemical resistance, for example, the mono-resorcinyl-triazines do not interact with certain metal ions (e.g., catalysts or production-related impurities) or strong alkali as opposed to BTZ.

For a HALS to be effective, it must be capable of trapping free radicals once they have formed. They act as radical scavengers in the autoxidation cycle and inhibit the photo-oxidative for the degradation of polymers. They are effective in retaining surface properties such as gloss and prevent cracking and chalking.

In line with the technology people-oriented service concept, CHEMK has very strong R&D capability to meet customers’ demands and focus on this area to meet future technical challenges. And CHEMK can provide a one-stop solution from formulation conception to research and development, from production to delivery to customers.

As we understand that our customers’ success is our success, we can work hand in hand with them to identify, invest in, and implement sustainable enhancements. Our R&D team drives innovation across all major product lines to achieve better solutions for higher productivity and efficiency. R&D also develops products and processes that are sustainable and more eco-friendly.

CHEMK will accelerate its capacity distribution in UV absorbent products, strengthen research and development of application, and provide more innovative products and application technology solutions to our customers and industries through multiple channels.
