Calplex 1T

Characteristics
Calplex 1T is a surface-treated high-quality filler made of natural calcium carbonate. Surface treatment makes the particles completely hydrophobic, which makes them more dispersible. Process characteristics are improved and moisture binding is decreased. The filler is used in the plastic imaterials, sealants and rubber industries.
