Solution for UV resistance of calcium-zinc stabilizer in injection nozzle scorching
Problem Phenomenon
The calcium-zinc PVC system shows UV resistance-related abnormalities in the injection nozzle scorching production stage, the pass rate decreases.
Cause Analysis
The lubrication characteristic of calcium-zinc stabilizers produces UV resistance problems under specific working conditions.
Solution
From the formulation perspective, adjust the calcium-zinc metal ratio, combined with process optimization to solve it.
Key Takeaway
The UV resistance problem of the calcium-zinc system in the injection nozzle scorching stage requires coordinated optimization of formulation and process.
