TPU Drying and Molding Conditions

December 16, 2020

Hardness below 90A, 3-4 hours at 80℃-90℃

Hardness below 95A, 3-4 hours at 90℃-100℃

When drying, low hardness specification should avoid high temperature and long time for high temperature will cause stick agglomeration and long time drying will make it yellowish
