GMT(Glass Mat reinforced Thermoplastics), or glass fiber mat reinforced thermoplastic composite material, which is made of fiber
as reinforcing material and thermoplastic resin as base material made by method of heating and pressurizing. It becomes widely
used composite material in the world and is considered as one of the most prospective development new material in the 21st
century.
1.Light weight
Taking one pallet size 850*680 for example, with same thickness, our GMT pallet is lighter; for same weight, our GMT pallet is
thinner. GMT pallet is lightest with high strength.
2.High Impact Resistant
Impact strength of PVC plate is less than or equal to 15KJ/m2, GMT pallet is greater than or equal to 30KJ/m2, comparing the
impact strength under the same conditions.
Drop hammer experiment in the same height shows that: when GMT pallet slightly cracked, PVC plate has been breakdown by drop
hammer. ( Below is the laboratory drop tester: )
3.Good Rigidity
GMT plate elastic modulus 2.0-4.0GPa, PVC sheets elastic modulus 2.0-2.9GPa. The following diagram: GMT plate bending effect
compared with the PVC plate under the same stress conditions
4.Not Easily Deformed
5.Waterproof
Water absorption rate <1%
6.Wear-resisting
Surface hardness shore: 76D. 100 minutes vibration with materials and pressure. Brick machine screw off, pallet is not destructed,
surface wear is about 0.5mm.
7.Anti-high And Low Temperature
Being used at min 20 degrees, GMT pallet won't deform or crack.
GMT pallet is able to withstand high temperature of 60-90℃, won't easily deform, and suitable for steam curing, but PVC plate is
easy to deform at high temperature of 60 degree
8.Long Service Life
Theoretically, it can be used more than 8 years
