Solution for melt pressure of calcium-zinc stabilizer in outdoor weather resistance
Problem Phenomenon
The calcium-zinc PVC system shows melt pressure-related abnormalities in the outdoor weather resistance production stage, product quality is unstable.
Cause Analysis
The zinc burning characteristic of calcium-zinc stabilizers produces melt pressure problems under specific working conditions.
Solution
From the formulation perspective, reduce lubrication, combined with process optimization to solve it.
Key Takeaway
The melt pressure problem of the calcium-zinc system in the outdoor weather resistance stage requires coordinated optimization of formulation and process.
