The plant problem
In rigid and flexible PVC, thermal instability drives yellowing, plate-out and torque swings. Without proper lubrication, throughput and finish suffer.
How Plectus solves it
Plectus Zinc Stearate acts as stabilizer and lubricant (internal/external), aiding mold release and color control. We tune dosage to matrix, filler and line speed.
What you gain
- More stable color and process
- Less sticking to equipment metal
- Dosage support and sampling
