Polycvinyl chloride, or PVC, is a modern synthetic polymer which belongs to the so called basic polymers. The chemical composition is (-CH2-CHCl-)n. Chloride 57% and oil 43% are used as raw materials to manufacture PVC. Thus PVC is less subject to oil stocks in contrast to other basic polymers. It matters when setting the price per PVC.
There are 3 ways to manufacture PVC:
- suspension polymerization (PVS-S);
- emulsion polymerization (PVC-E);
- casting polymerization or mass polymerization (PVC-M).
The main difference between PVC grades is average molecular weight which is characterized by K value (Fikentcher constant).
Suspension PVC (PVC-S)
Suspension PVC is used to manufacture goods by extrusion method, compression method, rolling, calendaring and casting method.
“KSK-grupp” LLC supplies PVC-S manufactured by
- open joint-stock company “Bashkir Soda Company”, Sterlitamak, Russia (see technical characteristics), and
- Shintech, the USA (see technical characteristics).
We supply PVS-S with standard K from 60 up to 70. Supplies of PVC resin with higher K value are possible at customer’s request.
| PVC Resin Grade | Usage |
| S-6669ZH | Window and door frames, siding |
| S-6359M | Plasticized and semi-rigid general-purpose goods (artificial leather, linoleum, films), general-purpose sheets |
| S-5868PZH | Films and bulky packaging |
| S-70U (counterpart to S-7059M) | Plasticized cable and medical compounds, film material, high-strength tubes |
| SE-1200 (Shintech) | Plasticized cable compounds, film materials, high-strength tubes |
Emulsion PVC (PVC-E)
Emulsion PVC is used to manufacture plastisol, linoleum, furniture fittings, artificial leather and rubber sheets.
“KSK-grupp” LLC supplies different PVC-E grades manufactured by Formoza Plastics, the USA. We can select a proper grade according to the customer’s demands.
PVC manufactured by casting polymerization or mass polymerization is not actually produced since PVC manufactured this way has a very specific usage and it is difficult to release it from the residual vinyl chloride.
