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…
Rubber Grommets Xidation Kinetics Curve The graph on the right is a typical oxidation kinetics curve of unsaturated carbon chain rubber. The ordinate is oxygen absorption, the abscissa is oxidation time, and the curve is S-shaped. There are three distinct stages in the whole curve. The AB segment indicates that Read more…
Thermal aging of rubber grommets The phenomenon that rubber or rubber grommets are aged during storage or use due to both heat and oxygen in the air is called thermal oxygen aging. Thermo-oxidative aging is the aging of various rubbers all the time, which is the main cause of damage to rubber Read more…
Aging and protection of rubber grommets 2 The influence of rubber grommets Rubber grommets are used in most cases as accessories for mechanical equipment, such as premature damage due to aging, which not only affects the user’s economic benefits, but sometimes causes significant damage to the property. In order to improve Read more…
Aging and protection of rubber grommets 1 Rubber grommets aging phenomenon In the process of processing, storage or use of rubber grommets, the phenomenon that the performance gradually deteriorates due to the influence of external environmental factors, until the loss of use value is called aging. The occurrence and development of Read more…
