Material, effectively reduces the cost of raw material and Product transport cost；The product with more thin structure, stretching in performance indications can be designed
Long rate reaches 20% or so, and the tensile strength of performance indications is between 8-12Mpa；Effectively reduce the density of material；Wherein add
Foaming agent and a certain proportion of toughener, by physical foaming method so that foamed interlayer uniform foam cell, can be at utmost
Ensure the impact resistance of product, while causing material internal almost uneven without stress and contraction by fretting map technology, subtract
Less or eliminate material film internal stress, the warpage issues of material are effectively improved, so as to improve product quality；Surface is not changed
The performance indications of layer, it is ensured that the performance processing of later process, degree of accuracy is high, and low production cost is nontoxic, pollution-free.
