T-PLAS 2023 | New Upgrade of Changhe Chemical Antioxidant Solutions for Southeast Asia


During T-PLAS 2023, 200 exhibitors from 20 countries around the world gathered at the exhibition themed “FURURE PROOFING THE REGION’S PLASTICS AND RUBBER SECTORS” to seek new growth in the plastic industry in the future. On the meeting, Changhe Chemical launched antioxidant solutions for the Southeast Asian market, providing customized products and services for improving product quality and efficiency in the PU and PVC industries.

With the increasing global demand for PU product quality in recent years, demands for environmental friendliness, no amine, UV resistance, and smoke resistance have flourished. From the current consumer’s constant pursuit of “small white shoes”, and even some sneaker collectors’ behavior of wrapping the shoe with cling film to prevent oxidation, it can be seen that end users are paying more attention to the anti-aging and yellowing resistance of products.

During the exhibition, Wu Yikai, Chief Engineer of Changhe Chemical, shared his practical experience in the oxidation resistance of PU products. He pointed out that in environments with severe industrial exhaust gases (including automotive exhaust and nitrogen oxides), adding the CHPHOS ™ HN and HS series products as additives can better prevent the yellowing of high polymer materials. The TPU/PU sponge-specific antioxidant launched by Changhe Chemical has achieved the effect of both anti-burning and anti-placement properties of the sponge through its unique formula, which has improved product durability for multiple TPU/Foam factories. In addition, in order to meet the diverse needs of customers, Changhe can provide customized services and package multiple products in one, provide suitable additives for customers’ specific needs, and reduce the cost of developing formulas for customers.
