Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen . COVID Resources.

Polymer degradation is a change in the properties tensile strength, colour, shape, etc. Polymer-based product under the influence of one or more environmental factors such as heat, light or chemicals such as acids, alkalis and some salts. These changes are usually undesirable, such as cracking and chemical disintegration of products. 6.

TGA results generated on a glass filled epoxy resin used for electronic applications. The epoxy resin undergoes thermal degradation beginning at ˚C with a mass loss of %. At ˚C, the purge gas flowing over the sample was automatically switched to oxygen and the carbon residue was burned off at ˚C with a mass loss of %. The Co-ordinated Research Project (CRP) on Stability and Stabilization of Polymers under Irradiation was initiated in based on the recommendation of the final Research Co-ordination Meeting on Radiation Damage to Organic Materials in Nuclear Reactors and Radiation Environment (IAEA-TECDOC) and the Advisory Group meeting organized in.

Many filled polymers, either thermoplastics or vulcanizable rubbers, have different chemical natures but exhibit common singular properties.
An understanding of why they do so is likely to be the source of promising scientific and engineering developments—and Filled Polymers: Science and Industrial Applications thoroughly explores the question.

Sudip Ray, Ralph P. Cooney, in Handbook of Environmental Degradation of Materials (Third Edition), Influencing Factors. Although thermal degradation of polymers and polymer composites occurs due to the application of heat, there are several factors that can influence this degradation process.
As a result, the nature of thermal degradation of different polymers or. The Handbook of Environmental Degradation of Materials explains how to measure, analyse, and control environmental degradation for a wide range of industrial materials including metals, polymers, ceramics, concrete, wood and textiles exposed to environmental factors such as weather, seawater, and fire.

Polymer Degradation: Principles and Practical ApplicationsAuthor: Wolfram Schnabel. Polymer degradation is a change in the properties—tensile strength, color, shape, etc.—of a polymer or polymer-based product under the influence of one or more environmental factors such as heat, light or chemicals such as acids, alkalis and some changes are usually undesirable, such as cracking and chemical disintegration of products or, more rarely.
The large macromolecular backbone of polymers is virtually harmless, being not directly available to living cells; however, low-molecular mass compounds such as additives, degradation products, and intermediates (e.g., oligomers, monomers) or metabolic derivatives, can be harmful to the living organisms in the environment [10,11].Author: Mihai Brebu.
Types of polymers degradation. The degradation of polymers usually starts at the outer surface and penetrates gradually into the bulk of the material Blaga ().Polymer degradation can be caused by heat (thermal degradation), light (photodegradation), ionizing radiation (radio degradation), mechanical action, or by fungi, bacteria, yeasts, algae, and their enzymes Cited by: With compact materials, this leads to an accelerated degradation in the center of the implant, which finally leads to a sudden breakage of the implant with a sudden release of the acid degradation products.
13 Considering a microcellular material, the diffusion path of the decomposition products is shorter, and the degradation products can. Polymers degrade by several different mechanisms, depending on structure and exposure conditions.
Degradation results from an irreversible change which leads eventually to failure. The most common types of degradation occur through chemical reactions, but there are a few important examples of degradation resulting only from physical changes. Degradation of Polymers the breakdown of macromolecules owing to heat, oxygen, moisture, light, penetrating radiation, mechanical stresses, biological agencies (for example, by the action of microorganisms), and other factors.
Depending on the agent, the following forms of polymer degradation are distinguished: thermal, thermal oxidative, photochemical. Although thermal degradation of polymers and polymer composites occurs due to the application of heat, there are several factors that can influence this degradation process.
As a result, the nature of thermal degradation of different polymers or their composites is also different. Even within the same type of polymer such variations may be by: Thermal degradation of polymers is molecular deterioration as a result of overheating. At high temperatures the components of the long chain backbone of the polymer can begin to be broken (chain scission) and react with one another to change the properties of the polymer.
Thermal degradation can present an upper limit to the service temperature of plastics as much as the. Chemically assisted degradation of polymers is a type of polymer degradation that involves a change of the polymer properties due to a chemical reaction with the polymer’s surroundings.
There are many different types of possible chemical reactions causing degradation however most of these reactions result in the breaking of double bonds within the polymer structure. The idea of mixing single available materials into compounds to fulfill a set of desired properties is likely as old as mankind.
Highly sophisticated polymer applications would simply be impossible without the enhancement of some of their properties through addition of fine mineral particles or synthetic or natural short fibers.
Many filled polymer.As a viscohyperelastic material, filled rubber is widely used as a damping element in mechanical engineering and vehicle engineering. Academic and industrial researchers commonly need to evaluate the fatigue life of these rubber components under cyclic load, quickly and efficiently.
The currently used method for fatigue life evaluation is based on the S–N curve, which requires .
