How Do the Antioxidants in Plastics Work?
One of the greatest benefits of using plastics is their longevity. However, when certain polymers are subjected to adverse conditions, such as extreme heat or exposure to certain chemicals, they will break down more quickly.

Oxidation is a chain reaction process involving free radical and hydroperoxide intermediates. Antioxidants inhibit this process by reacting with and decomposing these reactive species.
View MoreThe Importance of Antioxidant Additives in the Plastics Industry
The plastic antioxidants market is expected to register a CAGR of over 5% during the forecast period. The major factors driving the plastic antioxidants market are the replacement of conventional materials by plastics and increasing demand for polypropylene.
View MoreAn Introduction To Plastics Additives
Every activity in modern life is influenced by plastics and many depend entirely on plastics products. Imagine cars without synthetic bumper, dashboards, steering wheels and switches; medicine without plastic hypodermic syringes and artificial hip joints. And what about telecommunications, dependent on plastic telephones, circuit boards and cable insulation.

Plastic antioxidant works for the same purpose. antioxidant as used to improve polymers’ high-temperature stability.
Stabilizing additives are extremely important in the plastics industry, as they offer resistance to various degradation processes and chemical reactions that can harm the polymers. We’ve discussed antioxidants in this article, but we manufacture many other types of additives that are classified as stabilizers.
Antioxidants help in extending the life cycle of plastic, increase color deterioration, offer tensile strength and elongation, reduced impact resistance, cracking, and other surface deterioration.
Antioxidants are widely used in plastics, rubber, fiber, coatings, and adhesives industry. Basically, antioxidants are used in every polymers processing.
As the temperatures that the finished part must withstand rise, so must the level of antioxidants in the polymers to prevent long-term degradation and maintain the polymer physical properties.
Polymer degradation is a natural phenomenon that cannot be totally stopped. It tends to deteriorate the physical & mechanical like molecular weight, melt flow rate, appearance, processing and thermal stability properties of the polymer. To reduce such damages that occur during melt processing or under conditions of use, antioxidant stabilizers are developed.
Antioxidants protect polymers against oxidation by controlling molecular weight changes that lead to a loss of physical, mechanical, and optical properties.
Primary antioxidants and secondary antioxidants are the two major categories of plastic antioxidants, and plastic made from primary type is often combined with secondary to produce thermally stable plastic products.
Plastics tend to change over time due to exposure to heat, radiation, or a corrosive environment. The changes occur as a result of oxidative degradation and can severely affect the properties and service life of the polymers.
The plastic antioxidants market is expected to grow significantly during the next few decades, owing to unavailability of a perfect and economically viable substitute for plastic introduced in the market.
Additives are needed to stabilize polypropylene during melt processing and protect plastics against thermo-oxidative degradation during service life
antioxidants polymer additives are essential because they help prevent a process called oxidation. They are able to stabilize the plastic products’ qualities and slow degradation processes.
