high-efficiency plasticizers and oxidants for polymers

plasticizer - an overview | sciencedirect topics

Plasticizer - an overview | ScienceDirect Topics

Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of ...

polymer stabilizers

Polymer stabilizers

Polymer stabilizers (British: polymer stabilisers) are chemical additives which may be added to polymeric materials, such as plastics, to inhibit or retard their degradation. Common polymer degradation processes include oxidation , UV-damage , thermal degradation , ozonolysis , combinations thereof such as photo-oxidation , as well as reactions ...

how do plasticizers affect polymers?

How do plasticizers Affect Polymers?

Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt, the glass transition temperature (Tg), the melting temperature (Tm) and the elastic modulus of the finished product without altering the fundamental chemical character of the plasticized material.

Bioplasticizer - an overview | ScienceDirect Topics

The properties of the plasticizer and its compatibility with the polymer are modified by choosing a specific side-chain structure. It has been found that the product of esterification of glycerol with short-chain acids, e.g., glycerol triacetate (“triacetin”), can be used as a plasticizer for some polymers, e.g., thermoplastic PUs.

Antioxidants | Thermal Protection for Plastics | amfine.com

Antioxidants protect plastics and other materials against thermally induced oxidation. This process can lead to a number of undesirable effects, including discoloration, changes in melt viscosity, and deterioration of mechanical properties. As a result, the useful life of the polymer or final article is limited.

Antioxidants. Polymers will change over time when exposed to radiation, excessive heat and/or corrosive enviroments. These changes are the result of oxidative degradation caused by free radicals which form through hydrogen abstration or homolytic scission of carbon-carbon bonds when polymers are exposed to heat, oxygen, ozone, or light.
