TPU COMPOSITIONS FOR MELT COATING PROCESSES |
摘要 |
A TPU composition comprising two or more TPU polymers is disclosed. The TPU composition gives a broad process window for melt coating applications. The blend of TPUs give better processing than either of the individual TPU polymers used in the blend alone. This results in melt coating which gives less matt and glossy streaks and allows faster coating speeds along with lower coating weight. The two or more TPU polymers used in the blend have a different soft segment. The different soft segment is created by using different molecular weight polyol for the TPU polymers or by using chemically different polyols. |
