As an ISO 9001:2008 and 14001:2004 certified enterprise, we are indulged in manufacturing, exporting and supplying the best quality Antioxidant Masterbatches. The offered masterbatches find their application in making films, BOPP films, blow moulding and tapes. Our diligent professionals process these masterbatches by utilizing the best grade basic materials. In addition to this, the provided Antioxidant Masterbatches are also used to prevent thermal degradation.
- Uniform particle size
- Antioxidant in nature
- Longer shelf life
- High stabilizer efficiency
Plastics are normally ages much faster under the influence of oxygen, light and heat causing to stiffness of flexibility, loss of glass, discoloration, loss of strength and scratching.
Succeeding polymerization, almost every plastics are globated and transported to polymer converters, compounders and later producers of the end plastic product. In this course, the polymers go through various processing stages that normally relates extrusion of molten polymers. Each single production stag results in degradation, which is combines action of oxygen, shear and heat.
Thermo-oxidative degeneration happen by an independent radical performance known as autoxidation. This guides to a assortment of oxidative interreactions that either result in reduction in polymer's weight (chain scission) or improved polymer modular weight because of reamalgamtion reactions.
Kinds of Antioxidants
There are two kinds of antioxidants, which are as follows:
Primary: The obstruct the prime oxidation cycle by eliminating the generating radicals. These compounds are also known as Chain Breaking Antioxidants the is exercised the final end product. The stabilization makes sure performance over the life span of the final product. Further, they normal chemistry utilized as phenolic-supported.
Secondary :It is also known as Preventative Antioxidants because it interrupt the cycle of oxidation by inhibiting or securing independent radicals. The essential secured method is hydroperoxide decay where hydroperoxides are converted into non-radical, thermally stable and non reactive items. Further, secondary antioxidant is utilized as a process stabilizer, which is an optimum method to secure the polymer in the course of formulation, particularly when it goes many heat histories. Normal chemistry is used comprise thioesters or phosphites.
The combination of primary and secondary antioxidants are frequently exercised in a combination. In this manner, the polymer is secured both in the course of making step as well as throughout its functional life.
Our antioxidant masterbatches provide the customers to deal with decaying of plastics because of heat and oxygen.
There is sole kind of antioxidant masterbatches obtainable:
Antioxidant Master batch- This cut downs or intactly stops degradation of polymer because of oxidation.
