Industry Solution: How Molecular Sieve Powder Solves Moisture & Bubble Issues in Polyurethane
During polyurethane synthesis, trace moisture in raw materials is a critical factor affecting adhesive quality. Even a small amount of water (H₂O) reacts with isocyanate (RNCO) to produce carbon dioxide (CO₂) gas, forming dense tiny bubbles inside the adhesive. This leads to pinholes and bubbles on the product surface, severely impacting bond strength and surface gloss.
Powder molecular sieves is adsorbents with excellent dispersibility, low moisture content, and selective adsorption properties. It is widely used in polyurethane adhesive production to adsorb impurities such as H₂O, CO₂, and H₂S that affect product quality. Its functions include:
- Removing moisture
- Eliminating bubbles
- Smoothing surfaces
- Removing odors
- Extending curing time and service life
- Improving material uniformity and strength
Choose Xintao molecular sieve powder to meet the moisture removal and bubble elimination needs of polyurethane adhesives. With high adsorption efficiency, stable performance, and cost-effectiveness, it provides a reliable, worry‑free, and high‑quality solution for adhesive formulations.
Xintao Activated Molecular Sieve Powder
Xintao activated molecular sieve powder adsorbents are produced by adding special additives to synthetic molecular sieve raw powder, followed by high-temperature calcination. After high-temperature activation removes water, a precise and uniform microporous structure is formed inside. Based on the dual principles of “sieving + adsorption,” these powders offer strong selective adsorption capabilities – accurately capturing molecules smaller than their pore diameter while blocking larger molecules, achieving efficient separation.
As a powder material with selective adsorption properties, they can be directly mixed into polyurethane, polyurea, and other product systems. They effectively remove moisture, eliminate bubbles, create a smoother product surface, extend curing time and service life, improve material uniformity, remove residual odors, and comprehensively enhance product quality.
