TPU Nucleating Agent
Introduction to Materials
Material Overview
Qihao® Q33T TPU nucleating agent is a stiffness-enhancing nucleating additive specially developed for thermoplastic elastomers such as TPU, TPR, and TPE. It has an active ingredient content of up to 99% and appears as a white powder. This product can efficiently promote crystal nucleus formation, refine spherulite size, and improve the crystallinity of the material, thereby enhancing the rigidity, deformation resistance, and heat resistance of the products, as well as improving dimensional stability. It can also accelerate the crystallization rate, shorten molding cycles, facilitate demolding, and improve production efficiency in injection molding, extrusion, film blowing, and pelletizing processes.
QiHao® Q33T TPU Nucleating Agent is a stiffness-enhancing nucleating additive specially developed for thermoplastic elastomers such as TPU/TPR/TPE, with 99% active content and white powder appearance. This product can efficiently promote nucleation, refine spherulite size, increase crystallinity, thus improving product rigidity, deformation resistance, heat resistance and dimensional stability. It also accelerates crystallization rate, shortens molding cycle, facilitates demolding, and improves production efficiency of injection molding, extrusion, blown film and compounding processes.
This product can achieve a significant stiffness-enhancing effect within the recommended addition range of 0.3-0.5%, while maintaining a good balance of strength and toughness in the material. The product is easy to disperse, does not easily agglomerate, does not affect the natural color of the product or subsequent coloration, has excellent thermal stability, and poses no risk of decomposition or precipitation under conventional processing temperatures. It can improve the surface smoothness and gloss of the product, enhancing its appearance quality.
