About the Company
Bontecn Group China, formerly known as Longyang Chemical, was established in 2003. It is a group company specializing in the production of plastics and rubber additives. It is a professional enterprise integrating scientific research, development, sales, service and investment
The company is committed to developing products with international advanced level, and the raw materials needed for production are also purchased from the world's top technology manufacturers, with stable and reliable quality. At present, the company has 5 senior R&D personnel, more than 20 intermediate R&D personnel, and more than 20 cooperative teams With advanced process technology and perfect detection means, we constantly explore, devote ourselves to research and development, and cooperate with scientific research institutes all the year round to constantly develop new products and processes At the same time, we have established a strict production control system and quality management system, adhere to the market-oriented and user centered business policy, and strive to provide customers with satisfactory products and considerate services. Our products have been exported to North America, Latin America, the European Union, Asia Pacific, Africa and other countries and regions Since its establishment, the company has been deeply praised and recognized by customers at home and abroad with the business philosophy of "promoting development with quality and cooperation with integrity", and has won a good reputation in the industry
Product advantages
1). The temperature range is wide, and its hard products can be used for a long time in the range of 40 ºC -98 ºC.
2). The mechanical properties are excellent, and CPVC can still maintain strong rigidity at temperatures close to 100 ºC, meeting the rigidity requirements of equipment and pipelines under these temperature conditions.
3). Good chemical corrosion resistance, still has good acid, alkali, and chemical resistance under high temperature conditions, far better than PVC and other resins.
4). Good flame retardancy, CPVC has excellent flame retardancy and self extinguishing properties, with a limit oxygen index of 60. It has characteristics such as no flame dripping, limited flame diffusion, and smoke generation.
5). Low thermal conductivity, heat-resistant pipes processed with CPVC have less heat loss and can eliminate the insulation layer.
6). Not affected by residual chlorine in water, polyolefin materials will decompose when encountering residual chlorine in water, resulting in cracks and dripping, while CPVC will not.
7). Good antibacterial properties, CPVC pipes can resist the erosion of morphological bacteria and have antibacterial properties.
8). CPVC processing and molding are the same as PVC, simple and convenient.
