Why Extnder oil and rubber process oil add to natural rubber ?
Rubber process oils and extender oils are added to natural and synthetic rubbers for a lot of reason , for example :
- Reduce belending temperatures during processing and prevent scorching or burning of the rubber polymer when it is being ground to a powder.
- Decrease the viscosity of the rubber and thereby facilitate milling, extruding and general workability of the rubber compound .
- Reduce mill and calendar shrinkage, to aid the dispersion of fillers, and to modify the physical properties of the vulcanized and/or finished rubber compound.
