Product introduction of GPO-3 sheet :
GPO-3 laminated sheet is the low smoke and halogen free insulation sheet which was made of fiberglass and polyester resin , the fiberglass was impregnated in polyester resin with the aluminium hydroxide material and then press under the high temperature & pressure by machines . This material with very nice properties on environmental protection , because it is the low smoke and halogen free material ; As we known , halogen will little bit effect to the environmental and human bodies , and also if the material is not low smoke , it will be have hidden dangers when breaking out of fire on the rail traffic As we know , the rail traffic projects such as high-speed rail and metro requested mentioned properties , they required fire resistance , low smoke and non-toxic if breaking out of fire when high-speed rail or metro running . All of these good properties will save the lives of the people who are in the carriages . To avoid any mistake , the relevant project required EN45545 test report . It is very difficult to pass the test due to the high quality requirements .
We also have the UL/RoHs/Reach etc. test report to meet more and more strict requirements from clients all over the world .
The Feature of GPO-3 material
1. It is the excellent insulation properties with CTI600 and very high mechanical property material
2. It is excellent Electrical Performance material with the arc resistance more than 180 seconds
3. It is the green product and recognized by latest RoHs and Reach.
4. It is the customized products can be machined as per client’s drawings .
5. It has very excellent on temperature , the temperature index of this materials is from -270 to 155 degree centigrade , it can adjust to very low and high temperature when running.
6. It has the advantage on low smoke material and halogen free, it will save the lives when breaking out of fire when running in rail traffic .
The application of GPO-3 sheet
GPO-3 laminated sheet and machined parts are application to rail traffic , such as metro , CRH train , high speed rail etc. most of them are used as the insulation sheet , insulation support and cover in switches , because it has very excellent properties on electrical and mechanical , one of the most important is the low smoke , non-poisonous , halogen free and good fire resistance with EN45545 certificate and arc resistance .
As we know , it is very important to rail traffic of the safety , Railway traffic is a highly intensive place for people , low smoke , non-poisonous and good fire resistance are top important performance to ensure safety running. Actually , most of the train manufacturers in China have already contacted with us to supply this material , we have so rich experiences on it .
