In the production and formulation of polyurethane (PU) products, trace moisture is a critical factor that can lead to significant quality issues.
Residual water in raw materials such as polyols reacts with isocyanates, generating carbon dioxide, which can cause bubbles, foaming, and other defects.
The exothermic nature of this side reaction also shortens the working time (pot life) of the formulation, directly affecting product quality and process stability.
To address this industry challenge, Shanghai Joozeo offers a polyurethane-specific series of molecular sieve activated powders as an efficient and reliable solution. Derived from high-temperature activated molecular sieve raw powder, this material is thoroughly dehydrated and provides exceptional adsorption activity and dispersibility. When added to PU systems, it quickly and selectively removes trace moisture from the raw materials, effectively preventing unwanted reactions between water and isocyanates at the source.
Using Joozeo’s molecular sieve activated powder helps eliminate foam and bubble defects caused by moisture, resulting in improved appearance and enhanced physical properties of the final product. Additionally, it stabilizes the reaction process and significantly extends the pot life of the formulation, giving manufacturers greater operational flexibility. It is an ideal additive for ensuring consistent performance and high-efficiency production in polyurethane applications.
Shanghai Joozeo is committed to providing professional adsorption solutions that support the PU industry in improving product quality and manufacturing efficiency.
