Cold resistance solution for calcium-zinc stabilizer in sheet calendering
Problem Phenomenon
The calcium-zinc PVC system shows cold resistance-related abnormalities in the sheet calendering production stage, with production capacity limited.
Cause Analysis
The initial coloring characteristic of the calcium-zinc stabilizer produces cold resistance problems under specific working conditions.
Solution
From the formulation perspective, add antioxidant and combine with process optimization to solve.
Key Takeaway
The cold resistance problem of the calcium-zinc system in the sheet calendering stage requires two-way adjustment of formulation and process.
