Technical description
When PVC yellows, rubber sticks in the mold or masterbatch fails to disperse pigment consistently, the bottleneck is usually lubrication and stabilization — not only the resin. Plectus Zinc Stearate works as a thermal stabilizer and lubricant (internal/external), aiding mold release and process control in PVC, elastomers and pigmented compounds. Supplied with purity and particle-size control, traceable lots and technical support to tune dosage in your matrix.
We recommend evaluating polymer matrix, thermal cycle and process conditions before setting optimal dosage. Our application team supports lab and pilot trials through industrial qualification.
