Overview:
TMT has been committing to applying new polymer material technology to various parts of the car body, including fiber reinforced resin foam materials, aramid honeycomb materials, carbon fiber materials. With the characteristics of lightweight, low carbon, safety, etc., we have realized mass application on exterior products of rail vehicles.
Material technologies：
· Inner layer- (PMI) polymethacrylimide, aramid honeycomb, (PET) polyethylene terephthalate, etc;
· Skin layer- composite materials such as carbon fiber, glass fiber, etc.
Main characteristics:
· Lightweight product: Reduce the weight by 30% to 40% compared to traditional aluminum alloy products.
· Environmentally friendly materials: Meet the requirements of EU banned and restricted substances; material fire hazard level meets UL94-V0 and EU EN45545-2 HL2/HL3.
· Thermal insulation and noise reduction: Integrated composite technology of material structure and function significantly improves the thermal insulation.
· High strength:
