Solplus™ polymeric dispersants, also known as hyperdispersants, are polymeric materials designed to offer significantly higher levels of performance for thermoplastics, thermosets and liquid colorants.

Solplus™ polymeric dispersants for thermoplastics applications

The use of dispersants to aid in particle size reduction helps deliver product performance in thermoplastics such as engineering plastics (PA, PBT, PC) and common thermoplastics (PP, PE, EVA or PVC).

The use of the optimal dispersant can enhance color strength and mechanical properties, while improving overall throughput and processing costs.

Lubrizol offers various high-performance products for masterbatch and compounding applications with the Solplus™ polymeric dispersants product line.

PP/Calcium Carbonate Masterbatch: Increase loading up to 85% and improve dispersion with Solplus™ DP310 hyperdispersant

Calcium carbonate masterbatch concentrates can typically achieve 75% loading with existing wax technologies. Now they can obtain higher filler loadings up to 85% with Solplus™ DP310 hyperdispersant. Its excellent dispersing capabilities helps improve manufacturing efficiencies and provide high quality PP masterbatch.


Improve processability of highly loaded Nylon 6 masterbatch dispersions with Solplus™ DP320 hyperdispersant

Solplus™ DP320 hyperdispersant is a preferred option to meet the requirements for processing efficiency of nylon masterbatch compounds and to deliver good aesthetics.

It offers:

  • Improved processability resulting in an increase of overall throughput and a decrease in costs due to: lower filter pressure, reduced extruder torque, effective dispersion
  • Increased color strength at low and high filler loading
