Description
Technical field
The present invention relates to synthetic leather field, particularly relate to a kind of TPU foaming synthetic leather.
Background technology
Along with the raising of people's living standard volume and the attention to environmental conservation, TPU synthetic leather is increasingly liked by people
Like, but the high cost of TPU also limit its development.The PTU foam leather thickness of Italy reaches 3.5mm, and density is only 0.4g/cm3
Left and right, and the density of China's similar TPU foam leather is 0.58-0.67g/cm3, materials are more, only refer to from raw materials consumption one
From the point of view of Biao, gap is the biggest.Therefore, reduce raw materials consumption, improve product quality and profit, become the mesh that we make great efforts
Mark.
Summary of the invention
Present invention mainly solves technical problem is that: for the deficiencies in the prior art, it is provided that a kind of TPU foaming synthetic leather,
Can solve the problem that existing foaming synthetic leather raw materials consumption is big, foam high in cost of production defect.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of TPU foaming synthetic leather,
