Jiangsu Junyuan New Material Co Ltd, located in Rudong Economic Development Zone, participated in the 22nd China International Industry Fair (CIIF) on Sept 15, displaying its latest self-developed new flame retardant and wear-resistant composite board for rail transit vehicles.

Adopting the technology of fabric reinforcement, the new flame retardant and wear-resistant composite board initially remedies the production detects of traditional flame retardant sheets. With the characteristics of multi-function, high performance and low cost, it has obtained a national utility model patent.

The product has received high attention and affirmation from the industry since its debut, and was named an Outstanding New Material Exhibit at the CIIF, making Junyuan the only award-winning new material enterprise in Jiangsu province.

Jiangsu Junyuan New Material specializes in the research and development and production of aramid paper honeycomb core materials. Compared with metals and glass fibers, the material has the properties of light weight, high strength, flame retardant capacity, insulation and heat preservation, and is widely used in aircraft, high-speed railways, boats and other products.

At present, Junyuan has a 95 percent share of the rail transit industry market.

Traditional fire-proof sheets for vehicles generally use kraft paper as reinforcement material, which has complex production processes and relatively high production costs and defective rates.

"We use fabrics as reinforcement materials. They greatly enhance mechanical and flame retardant properties," said Ma Yumei, general manager of Jiangsu Junyuan New Material. "We also greatly shorten the original 'fireproof board veneer + prepreg + composite' process to reduce the direct material cost by more than 25 percent, which, added to the reduction in labor costs, brings the cost of the whole fire retardant door panel down by more than 30 percent."
