For temperatures below approximate to 38 degrees C, the response to the thermo-oxidative aging is independent of specimen length. Therefore, in determining the lifetime of gaskets with complex geometry, longer specimens are recommended to provide more reliable results than those suggested by the ...
A thermal oxidative aging program using the above technique nylon / acrylonitrile - butadiene - styrene resin blend material with excellent heat aging properties, liquidity and good; and good notched impact resistance, chemical resistance and mechanical properties can be used for automotive interior trim...
AgingDynamically vulcanized poly(vinyl chloride)/epoxidized natural rubber (PVC/ENR) thermoplastic elastomers (TPEs) were prepared following a semi-efficient vulcanization system (semi-EV) with the incorporation of di-ethylhexyl phthalate (DOP) as a plasticizer. The PVC/ENR TPEs were melt mixed at ...
The hardness, elongation at break, tensile strength, modulus, compression stress relaxation and permanent compression set of the rubber vukanizates in thermo-oxidative aging were described. 循此基本规律可预测橡胶及其制品的贮存或使用寿命,建立橡胶耐热氧老化性的合理评定方法,以及构成常温叠合曲线来研究弹性...
Based on the experimental results and using dynamic-network model, a mechanical-chemical-diffusion model is proposed to predict the changes in natural rubber properties during thermo-oxidative aging considering the effect of the natural rubber curing system. In the chemical part of the model, the ...
Influence of thermo-oxidative aging on chemical composition and physical properties of polymer modified bitumens. Constr Build Mater 2012;26:350-6.N. Dehouche, et al., "Influence of Thermo-Oxidative Aging on Chemical Composition and Physical Properties of Polymer Modified Bitumens," Construction ...
This study investigates the impact of magnesium oxide (MgO) nanoparticles on the thermo-oxidative aging behavior of blends of polypropylene (PP) and ultra-high molecular weight polyethylene (UHMWPE). The samples, both unfilled and filled with MgO, were aged at 120 °C for varying durations of ...
The mechanical properties, dynamic mechanical properties, and thermooxidative aging behavior of the ternary blend were compared with those of the binary blends (i.e., PVC/ENR and PVC/NBR). It was found that the ternary blend exhibits mechanical properties which are superior to those of PVC/ENR...
The compressive stress relaxation tests of butadiene rubber (BR) at different thermo-oxidative aging temperatures were carried out. Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) was used to observe the variations of internal groups before and after the thermo-...
