How rubber process oil produce ?
Process oils are derived from petroleum crude oil after the more volatile petrol and heating oil fractions have been removed by distillation. Process oils are mixtures of paraffinic, naphthenic and aromatic compounds of wide distribution of molecular weight. process oils are mixtures of paraffinic, naphthenic and aromatic compounds of wide distribution of molecular weight. process oils are used in the rubber industry to improve the process ability of rubbers and rubber compounds and increase the bulk of rubber in order to lower cost.Process aids are increasingly important for the rubber industry due to the following needs :
- improve efficiency and productivity
- lower energy consumption
- reduce production cost
- improve product quality
Rubber process oil function :
- Reduce viscosity
- Reduce elasticity
- Aid dispersion of fillers
- Reduce power consumption
Additional requirement
- Do not affect intended properties of finished products
- Act at low dosage level
- Non-toxic
