TESTIMONIAL
Customer Testimonials and Cases
I have visited your company and have a certain understanding of your company. If a company does not have a long-term strategic vision, it may be as successful as ever within three to five years, but in ten years' time, it will be easily eaten up by a weak rival who did not care about it at the beginning. The fact that Chongqing Xinqianwei Technology Co., Ltd. has developed so far shows that your company is thinking about the future development trend of the whole industry and adjusting its strategic planning reasonably, and taking the lead in making the layout.
On the recommendation of our engineers, we have been using your company's scratch-resistant agent QW-150, which is added at 3%-4% with our resin, and it has really improved the finish, abrasion resistance and smoothness of our products.
We have been using your rubber accelerator NS-80E, we have been using it in carbon black rubber, the vulcanization speed is very good, and it has improved our synthetic rubber use ratio, and the toxicity is also less, it is an efficient and safe accelerator, we will always use it.
CERTIFICATES
Technology guarantees product quality
Qianwei products are SGS certified, ISO certified, quality you can trust

Vulcanized nitrile butadiene rubber
Vulcanization system nitrile butadiene rubber mainly uses sulfur and sulfur-containing compounds as curing agents, but also can be vulcanized with peroxide or resin. As most nitrile-butadiene rubber products require small compression permanent deformation, low-sulfur and sulfur-containing compounds are often used, and sulfur-containing compounds (sulfur-free vulcanization system) or peroxides are used as curing agents. Sulfur accelerator system is the most widely used curing system of nitrile butadiene rubber. Sulfur can be used either sulfur powder or insoluble sulfur. As the solubility of sulfur in nitrile-butadiene rubber is lower than that of natural rubber, attention should be paid to controlling the amount of sulfur. With the increase of the amount of sulfur, the tensile stress and hardness increased, and the heat resistance decreased, but the oil resistance increased slightly and the cold resistance changed little. General soft rubber because the unsaturation of nitrile butadiene rubber is lower than that of natural rubber, the amount of sulfur needed can be less, generally 1.5 phr, vulcanization accelerator can be slightly more than natural rubber, commonly used 1 phr 3.5 phr. The optimum amount of sulfur for soft vulcanizate of nitrile rubber is about 1.5 phr. The amount of sulfur required for nitrile-butadiene rubber with different acrylonitrile content is not the same. When the content of acrylonitrile is high and the relative content of butadiene is low, the amount of sulfur required can be reduced due to the reduction of unsaturation. For example, butyronitrile-18, sulfur 1.75 phr, butyronitrile-26, 1.5 phr and 1.75 phr, have good comprehensive properties. The combination of low sulfur can improve the heat resistance of vulcanizate, reduce the compression permanent deformation and improve other properties, so nitrile butadiene rubber often adopts low sulfur (less than 0.5 phr of sulfur) and high accelerating curing system.
Optimization measures for dispersion of rubber mixing
In the process of rubber mixing, the dispersion of fillers and compounding agents has an important influence on the properties of the final rubber products. In order to achieve the best dispersion and product quality, the following optimization measures are available:
