PET core grooving & drilling sheets

PET core grooving & drilling sheets has the advantages of light weight, high strength, low glue absorption rate and good processability. It is used to fill the internal space of wind turbine blades, which greatly improves the structural strength of the blades and reduces the weight of the blades. At the same time, the PET foam can be used to adjust the extrusion process as a filling material for the casing and hub of the engine room, so as to enhance the strength of the structure while further reducing the weight of the wind turbine.
