PVC technical insights from the field.
Troubleshooting and formulation notes for production and QC teams: from orange peel and stabilizer choice to whiteness.
How to choose the K-value of PVC resin for rigid and soft products
K57, K65 or K70? What K-value means, how it affects processing and product strength, and which grade suits pipe, film, cable and hose.
CPE or ACR: choosing an impact modifier for pipe, roofing and gutters
The two most common impact modifiers for rigid PVC have different strengths. When CPE makes more sense, when ACR does, and where MBS fits.
Tin or CaZn stabilizer for clear rigid PVC film
Clear rigid film demands excellent clarity and early color. How tin and CaZn stabilizers compare, and the other components that decide the result.
What causes orange peel on PVC pipes, and how to check for it
Orange peel rarely has a single cause. How to separate fusion, lubrication, temperature and die issues before you change the formulation.
Lead or CaZn: what to consider before you switch
Moving from lead to CaZn is more than swapping one material. How they differ, what changes in lubrication, and how to transition safely.
Uneven ceiling-panel whiteness: common causes and how to check
Ceiling panels that look different side by side usually trace back to the formulation, raw materials or heat history. Here is how to track it down.
