Process of PVC calendering film
- PVC Resin SG-3 Or SG-5 ,K Value 60-75 .
- Mixed process: PVC resin with Plasticizer, Lubricants, stabilizers ,pigments and filler. From mixer or mill ,then the extrusion .
- Four-Roll calendering process which compresses and rolls the plastic into a flat film or sheet. Finishing equipment cooling and take-off the films with embossed or plain rolls.
- Finished rolls.
- Inspection ,can test surface, tensile strength ,plasticizer extraction/migration, elongation ,flame-retardant, breakdown and so on .
- Packing and shipping.
