Sumitomo Antioxidant

Product description：

GP has superior processing stability and is very suitable for the production of membrane materials. Compared with the traditional classification & phosphorus combination system, it can be used as a single component, thereby reducing the amount of additives added. Meet higher environmental protection and health needs.

Chitec·Antioxidant

Product description：

In the manufacture, molding and use of plastics, heat sources at different temperatures, such as the contact points between the polymerization catalyst and the carbon chain, trigger different degrees of oxidation reactions. The mechanism of this oxidation reaction can be summarized as a spontaneous oxidation cycle in the form of free radicals. The best way to prevent thermal aging is to capture various free radicals and peroxides generated during the spontaneous oxidation cycle, especially the long-lived peroxy free radicals and peroxides. Products that can capture free radicals are called primary antioxidants, and products that can capture peroxides are called secondary antioxidants.

Chitec·Ultraviolet Absorber

Product description：

Ultraviolet absorbers can quickly convert the absorbed light energy into low-harm heat energy, and then continue the process of absorbing light. The theory of action of ultraviolet absorbers is that after absorbing light energy, the molecular structure is converted into an excited state, and then most of the absorbed energy is consumed through molecular resonance to return to the original state, and the light energy starts to be absorbed again.

Chitec·Light Stabilizer

Product description：

The light stabilizer mainly protects the physical properties such as gloss and tensile strength that will be damaged by free radicals, and protects the color. The combination of light stabilizer and ultraviolet absorber can get a huge synergistic effect, so it is usually used in combination. The most important thing to choose hindered amine is to know the material, additives and thickness of the application. Larger hindered amines are recommended for thin parts applications, and small molecules are recommended for thick parts applications.
