In the demanding world of polymer processing, even trace amounts of moisture can lead to significant manufacturing defects, impacting product quality and performance. For plastics and rubber manufacturers seeking to eliminate issues like blistering, bubbling, and pinholes, Calcium Oxide (CaO) desiccant presents a highly effective solution. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer of polymer additives, offers high-quality Calcium Oxide desiccant to address these critical challenges.

Calcium Oxide desiccant, often called lime desiccant, is a potent moisture scavenger that operates through irreversible chemical bonding. Unlike conventional adsorbents, CaO reacts with water to form calcium hydroxide, permanently removing moisture from the polymer matrix. This chemical reaction is crucial during high-temperature processing, where absorbed moisture can vaporize and create internal voids, leading to surface defects on the finished product.

How CaO Desiccant Improves Polymer Processing

  • Eliminates Blistering and Bubbling: By chemically absorbing moisture present in polymer compounds, fillers, or absorbed from the environment, Calcium Oxide desiccant prevents steam formation during vulcanization or extrusion, thereby eliminating surface defects.
  • Enhances Product Quality: The reduction in internal voids and surface imperfections directly translates to improved physical properties, better aesthetic appeal, and enhanced durability of the final polymer or rubber product.
  • Cost-Effective Solution: As an economical and efficient moisture absorber, CaO desiccant provides a high return on investment by reducing scrap rates and improving product yield. We are a leading supplier of polymer processing aids.
  • Excellent Dispersion Properties: Our specially treated fine calcium oxide powder ensures good dispersion within host polymers, allowing for homogeneous moisture absorption and consistent results.

Applications in Various Polymer Systems

Calcium Oxide desiccant is widely employed in several polymer applications:

  • Rubber Compounds: Particularly beneficial in low-pressure curing processes for automotive seals and window profiles, where moisture can cause porosity and irregular characteristics.
  • Plastics Manufacturing: Used in PVC compounds, carpet backings, and polyurethane systems to prevent moisture-induced defects, especially where sensitive ingredients like isocyanates are present.
  • Cable Industry: Assists in low-pressure curing processes crucial for producing high-quality electrical cables.
