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.

Polymer Additives Primary and Secondary Antioxidants. Practically all polymer materials undergo oxidative degradation reactions occurring at one or all of the manufacturing, processing and end-use stages. Antioxidants are highly effective in preventing this degradation to the extent that color development, physical and mechanical property loss is kept within acceptable limits. The diagram
Selecting Antioxidants for Adhesives & Sealants Antioxidants are used in a variety of adhesive formulations to protect against degradation caused by reaction with atmospheric oxygen.Excessive oxidation generally results in undesirable changes in the adhesive's mechanical, aesthetic, or bonding properties that may in turn cause damage (like discoloration, viscosity, skin formation, etc.) to

Butadiene rubber, synthetic rubber widely employed in tire treads for trucks and automobiles. It consists of polybutadiene, an elastomer (elastic polymer) built up by chemically linking multiple molecules of butadiene to form giant molecules, or polymers.The polymer is noted for its high resistance to abrasion, low heat buildup, and resistance to cracking.
The term polymer is commonly used in the plastics and composites industry, often as a synonym for plastic or resin.Actually, polymers include a range of materials with a variety of properties. They are found in common household goods, in clothing and toys, in construction materials and insulation, and in numerous other products.

DABCO (1,4-diazabicyclo[2.2.2]octane) is an organic compound with the formula N 2 (C 2 H 4) 3. This colorless solid is a highly nucleophilic amine base, which is used as a catalyst and reagent in polymerization and organic synthesis. Quinuclidine has a similar structure, with one of the nitrogen atoms replaced by a CH group. Reactions and applications. The pK a of [HDABCO] + (the protonated
Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate.The weight percent of vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. Broadly speaking, there are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used.

Ascorbic acid is an organic compound with formula C 6 H 8 O 6, originally called hexuronic acid.It is a white solid, but impure samples can appear yellowish. It dissolves well in water to give mildly acidic solutions. It is a mild reducing agent.. Ascorbic acid exists as two enantiomers (mirror-image isomers), commonly denoted "l" (for "levo") and "d" (for "dextro").
Lignosulfonates, or sulfonated lignin are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping.. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. The electrophilic carbocations produced during ether cleavage react with bisulfite ions (HSO 3

Polymers are large, easy to create and made up of a repeating molecular pattern created by units called monomers. In plastic bags, these repeating structures are made of ethylene. Ethylene is chemically changed into polyethylene, the building block of all plastic bags. Polyethylene is made up of many winding chains of carbon atoms, interlaced with and bonded to hydrogen atoms. Because plastic

However, the synthetic rubber was more difficult to make, had less tackiness, and required more adhesive in making a tire than natural rubber. These problems had to be overcome to produce a reliable general purpose rubber. On March 26, 1942, the representatives of the companies and the U.S. government agreed upon a "mutual recipe" to produce the GR-S rubber. The recipe consisted of
