Calcium Oxide



HYGROSCOPE GR is a soft granule of 80 % calcium oxide coated with special dispersing agents to delay reactivity and is used as a desiccant in rubber compounds which are cured pressurless (Micro wavesystem, LCM, Hot air or Fluid bed) Moisture which presents in all rubber chemicals, especially fillers, will be absorbed and the calcium oxide will change to calcium hydroxide after reaction with the moisture. HYGROSCOPE GR should be used in order to prevent blisters and porosity in the following rubber processes; Pressurless continuous curing systems like Micro wave, LCM, Hot air, Fluid beds, Low pressure curing in the cable industry, In cases where the influence of humidity in rubber compounds should be suppressed. HYGROSCOPE GR can be supplied in sachets containing any weight between 0.5 kg and 20 kg to suit customers requirements at no extra cost.
