High extruder torque, yellowing, moisture or sub-spec impact — pick the symptom and see the additive package Plectus engineering recommends for your process.
Slow extruder output, flow breaks, high torque and energy consumption.
Yellowing, property loss and degradation over long heat cycles.
Water uptake, additive migration and white film formation on surfaces.
Inconsistent rheology between lots, phase separation and poor dispersion.
Brittle failure in ABS, PVC and polystyrene under load or low temperature.
Residual odor, low mechanical performance and microbial contamination in post-consumer material.
Need to meet Glow Wire, UL94 and international standards without performance loss.
Low feed conversion and ruminal instability in feedlots and pasture systems.

High torque, blooming, mold sticking or fragile thermal stability are rarely fixed with a generic commodity. Metallic stearates and polyethylene waxes belong when the plant needs predictable flow, clean release and consistent finish, with specification and trials, not dosage guesswork.
Plectus’ featured industrial line covers zinc, calcium and magnesium stearates for PVC, rubber, masterbatch and powders, and micronized or flake PE waxes for extrusion and compounds.
