Multifunctional Dispersant Q-300
Q-300 is a multifunctional liquid dispersant specifically designed for PVC applications.
It effectively disperses titanium dioxide, organic and inorganic pigments, calcium carbonate, and AC foaming agents.
When incorporated into PVC formulations, Q-300 rapidly wets and disperses the target materials, ensuring smooth processing and stable, aesthetically pleasing end products.
Recommended dosage:
Typically added at 1–3% of the weight of the target dispersant—such as titanium dioxide, calcium carbonate, or AC foaming agents.
Actual dosage should be adjusted through incremental testing based on formulation needs.
Observed Results
High-Performance Dispersant LDP-110
LDP-110 is a high-activity super dispersant (99+%) in amber liquid form, designed for dispersing inorganic pigments and fillers.
It delivers excellent dispersion performance for titanium dioxide and calcium carbonate, enabling rapid wetting, viscosity reduction, and improved flowability.
By enhancing pigment and filler mobility, LDP-110 shortens mixing time and improves overall processing efficiency.
Recommended dosage:
Typically added at 1–3% of the total pigment/filler weight.
Actual dosage should be adjusted incrementally based on formulation testing.
