Functional PU Additives are general purpose additives for polyurethane. Yourun additive products include Defoaming Agent (Foam Inhibitor), Abrasion-resistant Agent, Antistatic Agent, Anti-yellowing Agent, Antioxidant, Anti-hydrolysis Agent, Mold Release Agent, Moisture Scavenger (Dehydrating Agent), Dispersant, Anti-settle Dispersing Agent, Viscosity Reducer, etc.
It is a common phenomenon that many additives have synergistic or conflicting effects. in order to ensure the functionality of additives in applications, the primary consideration is to avoid conflicting effects between additives; With years of deep research, some special additives have developed by Yourun, they not only solvethe functional problems, but also pass the adequate suitability assessment.
Representative products are as follows, please click the Product Model to see more details.
