Polymer combustion and smoke generation mechanism The combustion of the ruthenium polymer is generally caused by the external heat to decompose the flammable gas, and it is violently oxidized and ignited by mixing with the oxygen in the air. The combustion process generally includes steps of heating, melting, depolymerizing or Read more…
Flame retardant rubber grommets With the exception of a few synthetic rubbers, natural rubber and most synthetic rubbers are flammable or combustible materials, especially natural rubber and hydrocarbon synthetic rubber. Rubber grommets made of these rubber materials are also flammable or flammable, and generate a large amount of heat when Read more…
Color rubber grommets manufacturing method The coloring methods of rubber grommets mainly include surface coloring and coloring of the mixture. The surface coloring is to spray the coloring agent onto the surface of the rubber grommets to color the rubber product. The method has a certain effect on static grommets. Read more…
Pigments for rubber grommets The coloring of rubber grommets is mainly based on pigments, and dyes are rarely used. Dyes are mostly used in hard transparent plastics, and there are also dyes mixed with some pigments in rubber, but few. A pigment is a colored substance that is insoluble in Read more…
Coloring system for Rubber grommets Traditional rubber grommets are mostly single black, and modern people require many rubber grommets to be brightly multi-colored. Therefore, the coloration of rubber is receiving increasing attention. Colorants are a class of materials that change the color of rubber. Rubber colorants are mostly pigments and Read more…
Effect of vulcanization on rubber grommets Most rubber grommets are used after vulcanization. After vulcanization, the rubber not only forms a bulk network structure, but also changes the chemical composition of the rubber. The oxidative behavior of the rubber is affected by the cross-linking bonds, the extra-network substances formed by the mutual Read more…
Impact of rubber side groups The side group has the same effect as the unsaturated carbon chain rubber, but its oxidation resistance is different due to the presence or absence of substituents on the double bond and the polarity of the substituent. The acrylate rubber in the saturated carbon chain Read more…
Factors affecting the thermal aging of rubber grommets The influence of the molecular structure of raw rubber The rubber grommets have different molecular structures, different oxidation sites, different oxidation and easy oxidation, different oxidation rates, different structural changes during oxidation, and different oxidation products. The influence of the main chain structure Read more…
Track rubber grommets oxidation process Two oxidation reactions Modern chemical analysis techniques such as infrared spectroscopy are used to track the oxidation process of the entire rubber grommets. The results of analysis of the oxidation intermediates and final products indicate that chain degradation or chain crosslinking reactions occur simultaneously during Read more…
Rubber Grommets Characteristics The elasticity at room temperature is a unique feature of rubber grommets, which is not available in any other material grommets, so rubber is also called an elastomer.The elastic elasticity of rubber is manifested in:① has a particularly large elastic deformation, can be stretched up to 1000% or Read more…
