Benefits of calcium carbonate in PVC Processing Bausano
Since calcium carbonate does not melt at processing temperature, the viscosity of the compound will be higher and flow will be lower. Therefore, the number of pipes manufactured per hour from compound A = N1, will be more than number of pipes manufactured per hour from compound B = N2. The cost of pipes per hour from compound A and B will be: Rs.
