UV resistance solution for calcium-zinc stabilizer in recycled material ratio
Problem Phenomenon
The calcium-zinc PVC system shows UV resistance-related abnormalities in the recycled material ratio production stage, with customer complaints.
Cause Analysis
The precipitation characteristic of the calcium-zinc stabilizer produces UV resistance problems under specific working conditions.
Solution
From the formulation perspective, reduce lubrication and combine with process optimization to solve.
Key Takeaway
The UV resistance problem of the calcium-zinc system in the recycled material ratio stage requires collaborative optimization of formulation and process.
