Answer:
UltraCarb products are differentiated by 3 physical characteristics:
• Mineral composition
• Particle size
• Surface modification
The amount of hydromagnesite and huntite is fixed at two different levels for the UltraCarb "LH" and UltraCarb "1200" series respectively. The "LH" series contains more than 60% hydromagnesite whereas in the "1200" series huntite is the main mineral fraction. The actual amount of hydromagnesite and huntite in each product series is defined in internal production specifications.
