As a large number of plastic products enter food contact applications, so do concerns about customer health and safety.
View MoreThings You Should Know About Plastic Antioxidants
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 can break down more quickly.
View MoreWhat Are the Uses of Antioxidants?
Antioxidants have a variety of uses in industry. They are most commonly used as food preservatives and supplements. The industrial and other uses of antioxidants can be summarized as follows.
View MoreApplication of Antioxidants
Antioxidants can delay or prevent the oxidation or self-oxidation process of polymers. They are called antioxidants. Antioxidants are a class of chemical substances.

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.
The plastic products that most commonly contain antioxidant additives include: A variety of pipes and fittings used in the building & construction industry Polyethylene films (PE films) used a variety of applications, from construction to food packaging Products and films made from polypropylene (PP)
Antioxidants are widely used in plastics, rubber, fiber, coatings, and adhesives industry. Basically, antioxidants are used in every polymers processing.
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.
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.
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.
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.
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
Primary antioxidants and thioesters are added to the polymer to provide end-use product stability while phosphites or phosphonites are added to provide color and processing stability during pelletization and extrusion/molding.
Antioxidants protect polymers against oxidation by controlling molecular weight changes that lead to a loss of physical, mechanical, and optical properties.
Plastic antioxidant works for the same purpose. antioxidant as used to improve polymers’ high-temperature stability.
