TYTAN™ CP-326

TYTAN Titanate Coupling & Dispersing Agents are molecular bridges at the interface between inorganic fillers (such as CaCO3, BaSO4, graphite, talc, carbon black, silica and metal oxides) and polymers (such as PP, PE, PVC, PBT, PET, ABS and rubbers). When incorporated into polymers, the coupling agent could improve filler loading, pigment dispersion, processability and composite mechanical properties to achieve the specification desired.

As a comparison, silane coupling agents only reacts with hydroxyl groups on the filler surface via water condensation of silanol-siloxane process, therefore it is suitable for glass, alumina hydroxide, magnesium hydroxide etc. The advantage of titanate coupling agents is that they not only react with hydroxyls, but also the free protons on the inorganic interface, which results in the formation of organic monomolecular layers on the inorganic surface forming the bonding for polymers.

Dosage is up to the property required and the filler type used is dependent on its surface area, the larger the surface area, the more Tytan titanate coupling & dispersing agent are needed. As a guide, the general dosage range is 0.2% ~ 2.0% by weight of filler.

Description

Pyrophosphate titanate

Yellowish liquid

Moisture resistance, improved flame retardation and anticorrosion

Benefits:
  • Increase filler dosage from 20% to 30% for cost saving without sacrificing mechanical strength.
  • Accommodate recycled polymer through “Repolymerization” of polymers.
  • Improve anticorrosion and flame retardation via pyrosphosphate ligand.
  • To achieve lighter weight component without sacrificing mechanical properties.
  • Reduce viscosity for easy processing.
