Cera de Polietileno (Lubrificante e Dispersante)

Compostadores de PVC e casas de cor e masterbatch usam cera de PE de baixo peso molecular como lubrificante externo e auxiliar de dispersão de pigmentos para reduzir o torque do fundido, melhorar a fluidez e aumentar a produtividade da linha, comprada por big bag e distinta da resina de polietileno base.

Typical Formulation Workflow
1
Polymer & Process Definition
Identify the resin and process (extrusion, molding, film) and the targets — thermal stability, clarity, flame retardance, slip, or color.
2
Additive Selection
Match stabilizers, antioxidants, plasticizers, lubricants, flame retardants, or masterbatch carriers to the polymer and processing temperatures.
3
Compounding Trial
Confirm loading and dispersion on a compounding or molding trial, checking processability, mechanicals, and aesthetics against the control.
4
Validation & Scale-Up
Verify long-term performance (heat aging, migration, weathering) and lock the formulation, packaging, and lot specs for production.

Polímeros e Resinas
Espessamento / Reologia
Short PE chains act as an external lubricant, migrating to the metal interface to reduce melt-wall friction and torque and raise throughput (low-MW wax grade is distinct from the PE resin and is sourced on demand)
