Anti-Aging Additives
Polyolefins (PO) are readily degraded by oxidation, thus antioxidants are frequently used in polyethylene (PE) and polypropylene (PP).
Keeping this in view, what are the additives used in plastic?
The most commonly used additives in different types of polymeric packaging materials are: plasticizers, flame retardants, antioxidants, acid scavengers, light and heat stabilizers, lubricants, pigments, antistatic agents, slip compounds and thermal stabilizers.
Also know, what additives can be added to polymers?
The most common polymer additives are stabilizers, plasticizers, lubricants and flame retardants. Stabilizers are added to prolong the useful life of a polymer formulation by protecting it from thermal and light-assisted oxidation.
What are polymer fillers?
Polymer Processing
Fillers are particulate material, such as minerals, diatamaceous earths, and talc, which are added to polymers to reduce cost. Fibrous reinforcements, such as glass and carbon fibers, are added to polymers to increase stiffness and to some degree strength.
Why are Stabilisers added to plastic?
Stabilizers. Stabilizers are ‘intentional additives’ used to prevent environmental effects (of heat, UV light, etc.) on the polymer. They are added to plastics to afford protection against heat (thermal), UV and mechanical degradation of the polymer during both processing and use.
What are phthalates?
Phthalates are a group of chemicals used in hundreds of products, such as toys, vinyl flooring and wall covering, detergents, lubricating oils, food packaging, pharmaceuticals, blood bags and tubing, and personal care products, such as nail polish, hair sprays, aftershave lotions, soaps, shampoos, perfumes and other …
What are the four additives when recycling a plastic?
To deliver what the customer is asking for, recyclers can use additives such as peroxides, antioxidants, chain extenders, elastomers, colorants, performance modifiers and nucleators to restore diminished properties or to compensate for undesirable attributes.
What are the 7 types of plastic?

What additives are added to polyethylene?
Additives commonly added to polyethylene include antioxidants (hindered phenolics and phosphites for process stabilization), antiblock compounds (e.g., silica, talc, and kaolin to reduce sticking of adjacent film layers), and slip agents (e.g., erucamide and oleamide to reduce friction).
What are the additives in plastics to leach out impacting land?
Additives such as phthalates and Bisphenol A (widely known as BPA) leach out of plastic particles. These additives are known for their hormonal effects and can disrupt the hormone system of vertebrates and invertebrates alike.
Does it take 500 chemicals to make plastic packaging?
It Takes More Than 4,000 Chemicals to Make Plastic Packaging New Research Finds. Researchers have found there are more than 4,000 different chemicals in plastic that’s used to house food and other everyday consumer goods. It’s pretty well documented the damage plastic does to marine life and the environment.
