一般特征
Desmomelt U 320 P is an aliphatic high-molecular-weight polyester polyurethane. It is a solid, non-yellowing, heat activation adhesive raw material in the form of granules and is therefore particularly suitable for thermoplastic processing (films, filaments, coextrusion). Desmomelt U 320 P is well suited for applications with low thermal activation temperatures, such as automotive, textile, footwear and furniture.
储存条件
Recommended storage temperatures: Temperatures higher than 30 °C should be avoided. Temperatures above 45 °C will lead to caking. Protect from direct sunlight, heat, moisture and foreign material.
