Solution for cold resistance of calcium-zinc stabilizer in cable extrusion
Problem Phenomenon
The calcium-zinc PVC system shows cold resistance-related abnormalities in the cable extrusion production stage, product quality is unstable.
Cause Analysis
The thermal stability characteristic of calcium-zinc stabilizers produces cold resistance problems under specific working conditions.
Solution
From the formulation perspective, increase auxiliary stabilizers, combined with process optimization to solve it.
Key Takeaway
The cold resistance problem of the calcium-zinc system in the cable extrusion stage requires coordinated optimization of formulation and process.
