Product Description
HYGROSCOPE P is a high-purity calcium oxide (95%) powder designed to delay reactivity and act as a desiccant.
It is widely used in PE Masterbatch, PP Masterbatch, Rubber Compounds, and PVC Plastisol that are cured pressurless using systems like Microwave, LCM, Hot Air, or Fluid Bed.
By absorbing moisture present in plastics, PE, PP, rubber, PVC chemicals, and fillers, HYGROSCOPE P transforms into calcium hydroxide, preventing blisters, porosity, and defects in the final products.
