Product Description
HYGROSCOPE GR is a soft granule desiccant containing 80% calcium oxide, coated with special dispersing agents to delay reactivity. It is specifically designed for rubber compounds cured pressurless using Micro Wave, LCM, Hot Air, or Fluid Bed systems.
It absorbs moisture present in rubber chemicals, particularly fillers, and converts calcium oxide to calcium hydroxide, preventing blisters and porosity in processed rubber.
