Does anyone have the specific process parameters for PVC production? For reference, they include PVC production temperature, degree of polymerization, polymerization time, maximum polymerization speed, etc. Does anyone have it? It is urgently needed!!
The parameters of 30, 45, 70, 100 and 120 are all different.
Then I want 30 cubic meters. Do you have any? If so, please send it to me. Thank you!
Different resin models have different production control indicators.
