是由新型酐单体及新型胺单体的新配方制成的聚酰氨酸树脂,经双向拉伸工艺生产的新型亚胺薄膜,它不仅具有普通聚酰亚胺薄膜的所有优异性能,且具有更高的尺寸稳定性,高弹性模量及低热膨胀系数。
一、技术要求:
6052E Low Expansion Coefficient Polyimide Film
With the application of Bi-axial stretching Technology, this brand polyimide film, the low thermal expansion coefficient polyimide film, is made from polyamic acid resins, which is obtained from a novel formula comprised of new anhydride monomers as well as a mine monomers. It not only processes good performance of ordinary polyimide film but also has better dimension stability, higher modulus of elasticity and lower heat expansion coefficient.
