Shang Hai Prior Chemical Scientific and Technical Co., Ltd. Was established in 2016. Relying on the resource advantages of China north chemical industries group, it is engaged in the trade of military materials such as nitrocellulose, pyrotechnic agents, chlorinated polypropylene, solid polyurethane, anti-graffiti and anti-adhesion coating, cellulose ether and its derivatives, and independently produces the nail fastening system with solid propellant, ammonium carboxymethyl cellulose and cellulose ether. The company's market share of hydroxypropyl methyl cellulose ether for automotive exhaust honeycomb ceramics in China exceeds 60%. At present, the company's key businesses are ammonium carboxymethyl cellulose for honeycomb ceramics of desulfurization and denitration catalyst, hydroxyethyl cellulose for plate catalyst and nail fastening system with solid propellant. The design capacity of ammonium carboxymethyl cellulose product is 500 tons / year. The company aims to achieve more than 60% market share in the desulfurization and denitrification industry and ammonium carboxymethyl cellulose for fluorescent lamp water-solvent powder. The production technology of the product was acquired from the development of ammonium carboxymethyl cellulose by China North Industries Group Corporation from 2013 to 2014, and was later improved and expanded in the company. Its chemical products include coatings, oil drilling, daily chemicals, glass fiber, leather oil, stationery, ink, and grinding and polishing industries, with particularly high market share in the honeycomb ceramics for automotive exhaust gas purification, gas desulfurization and denitrification, pyrotechnic agents, coatings and other fields. The nail fastening products with solid propellant is developed with imitation of the system of Nitroset company in the United States (a high-tech enterprise). At present, our company can achieve an annual output of 50 million solid propellant integrated nails. In the competitive market, the company will firmly stick to the idea of "quality first", take "creating first-class work, building product brand, shaping the excellent image of the company" as the quality policy, and set "the qualified rate of products leaving the factory reach 100%, and ensure customer's 100% satisfaction" as the quality goal.
