Title:
LOW-SHRINKAGE TPU FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/127069
Kind Code:
A1
Abstract:
Provided are a low-shrinkage TPU film and a preparation method therefor. The low-shrinkage TPU film is prepared from the following raw materials in parts by weight: 60-80 parts of TPU particles, 20-30 parts of polypropylene, 2-8 parts of calcium carbonate, 1-5 parts of a graphene material, 5-10 parts of glass fibers, and 0.5-2 parts of an antioxidant. The shrinkage rate of the TPU film is 0.5% or less, and the flexibility and good mechanical properties and processability of the TPU film can be ensured.
