GMT sheets for auto interior

GMT Materials used in Auto Interiors and exteriors: 1.Eco-friendly 2.Flame-resistance 3.High in intensity 4.Shaped simply

Cars will become lighter and cheaper and have to withstand stricter requirements on safety, comfort, and molding design in the future. So, it asks us to take more attention on light weight and easy molding composite on the manufacture of auto parts. GMT material with its competitive edge on this aspect caters to the demand, and many of the seat rear panel, dash board, and front end modules are made from GMT materials. It possesses excellent performance in many areas, such as light weight and high strength, anti-impact, and high loading. Moreover, it has a strong flowability which makes it easily to be made into complex shape auto parts, and makes it possible to produce auto parts with large surface area. GMT products have made a large progress in the past few years, and can meet the demand of now and will in the future.

 

 

Hard GMT sheets of high density employs PP resin as base material and glass fiber as reinforced material and possesses the specific gravity between 1.1-1.3. Our GMT sheet performs a lot of good characteristics, such as the light weight and high strength, good flowable ability and easy to mold, heat thermal deformation of 140°C,glass fiber content adjusted, and etc. GMT material is the ideal choice in lightweight vehicle manufacturing and can be made into complex auto parts which require high loading capacity.

Lightweight GMT sheet employs PP resin as base material and glass fiber as reinforced material. It has many advantages, such as high expansion rate, heat thermal deformation of 130°C, and glass fiber content adjusted. Furthermore, after the combination with non woven fabric by using of melt adhesive (film), they attaches well. It possesses good performances of sound insulation, heat insulation, and no smells emitted, and is applicable in the manufacture process of mold pressing or punch pressing, such auto parts like headliners, sunshade, hallstand, bottom panels are made by this way.

The right choice of Lightweight GMT Rolls can save cost and improve efficiency. The specification we made is 2.3m at most for width, and 10-50m for length, and moreover the gram weight of it is 800-2400g/m2.
