Marine airbag characteristics:Â
1. High strength: The polyamide cord thread for airbag is produced with high tension reinforced fiber. A cord thread has the strength more than 320N, and the cord fabric has consistent and reliable quality. Our company developed and manufactured high strength airbags with the higher strength steel wires and aramid fiber as skeleton materials on customers' request.Â
2. Wear resistance and anti-aging: An airbag often works in extreme conditions, for example, it is soaked in sea water, insolated in the direct sunlight and rolled in sand. Our marine is produced with natural rubber in a reasonable formula. The practice proves that airbag has high wear resistance and anti-aging ability, and the service life as long as 8-10 years.Â
