NEWECO Additive flame retardant resin for rail transit
1st, the application of additive flame retardant resin in rail transit
2nd, the requirements of rail transit for added flame retardant resin
3rd. Additive flame retardant resin for Neweco rail transit
1st, the application of additive flame retardant resin in rail transit
Rail Transit refers to the transportation mode with large capacity, fast speed, safety, on-time, environmental protection, energy conservation and land use, referred to as “rail crossing”, including subway, light rail, magnetic levitation, tram, Railways, motor trains, high-speed rail, new transportation systems, etc.
Considering flame retardancy, smoke toxicity, strength, cost, etc., the added flame retardant unsaturated polyester resin (hereinafter referred to as additive flame retardant resin) has high application value.
The main application of additive flame retardant resin in rail transit at this stage:
·Inside wall panel, top panel
·Assembled glass steel bathroom
·Whole glass steel bathroom
·Seat or seat frame
·FRP air conditioning air duct
·Car roof shroud
· Various complicated parts in the car, such as the inner wall panel and the side top panel of the three-dimensional curved shape, various special shapes of the cover panel, decorative parts, etc.
2nd, the requirements of rail transit for FRP products
There are many standard requirements for flame retardant resin FRP products in rail transit, including iron standard, German standard, European standard, American standard, British standard, legal standard, etc.
The main requirements of the iron standard are the following four standards:
·TB/T 3138-2006 Technical conditions for flame retardant materials for rolling stock
·TB/T 3237-2010 Flame retardant technical conditions for interior materials for EMU
·TB/T 3139-2006 Limits on the contents of materials and indoor air pollutants for rolling stock
·Iron total restricted substances
In addition, the main main criteria are as follows:
· German standard DIN5510-2:2009 Fire protection measures in rail vehicles Part 2: Raw materials and accessories
Combustion characteristics and combustion boundary effects; classification, requirements and testing procedures
· EU ROHS directive on restricting the use of certain harmful components in electrical and electronic equipment
·EU EN14582:2007 Halogen Free Report
·American standard UL94 plastic flame retardant grade
·British Standard BS6853:1999 General Specification for Design and Construction Fire Protection of Passenger Trains
·French standard NF F16-101/102 French track train flame retardant test
3rd. Additive flame retardant resin for Xinyang rail transit
