Polymer Additives
From the very beginnings of the plastic industry, it has been necessary to add materials to a basic polymer resin in order, at least, to make it processable. It has also been clear that additive materials are necessary to modify a resin, to improve properties that are desirable, and to eliminate or mitigate properties that are undesirable.
Additives are products, normally used in small quantities, which enhance the value of materials such as plastics, paints, lubricants by improving their process-ability, performance, and appearance during manufacturing and in use.
Plastic Additives compromise a major segment of HGIPL’s product mix, with the company established as primarily being an additive supplier to the polymer industry.
We manufacture various polymer additives intended for a vast variety of product applications.



Oxidation effect degrades all polymers. As a result, Anti-Oxidants are
added in Polymers to reduce the degradation effect & control flow behavior.
Under our brand, HINOX we have both Primary and Secondary Anti-Oxidants for a vast variety of Polymers such as PP,PE,PET,PBT,ABS,HIPS,PC& EVA.
