Rubber Process Oil characterizes:
Rubber process oils (RPO) are obtained from petroleum (crude oil), after the more volatile petrol and heating oil fractions have been separated through distillations. Process oil are mixtures of paraffin, naphthalene, and other aromatic compounds of various molecular weight distributions and are used as processing aid in manufacturing of rubber products. Rubber Process Oil different types have two general grades: Heavy and Light. RPO with a viscosity of 30 to 50 are titled as heavy (high viscosity) grade and as a positive point of RPO, Rubber Process Oil is nonhazardous and environment-friendly.
RPO application:
Rubber process oils function as a plasticizer, improving the processability and filter incorporation, or as an extender. Based on the finished product, there are extensive range of products. Moreover, wether effects on the grade and their usages, for example Light RPO grade is suitable for cold seasons and regions. On the contrary, the heavy grade is appropriate for the hot season and climate.
As an overall notion of the RPO application, about 2/3 of this product is applied in tire industries, and the rest is devoted to non-tire industries such as:
- Rubber tiles
- Conveyor belts
- Paints and coatings
- Aromatic RPO Usage
- Sponge rubber
- Hoses
- Latex products
Tires, lactic, automotive tires and tubes, bicycle tires, tire re-treading materials, belting, hoses, battery casings and containers, extruded products, technical molded goods, and rubber articles with reclaim rubber due to high solvency. Color stability, solubility, and thermal stability of Process Oil (furfural extract) make it ideal for molded articles, slippers, LPG tubes, floor tiles, etc. Other types of RPO, like Paraffinic RPO is extensively being used in Butyl rubbers, and Naphthenic RPO is a series of hydrocarbons that is also referred to as cycloparaffins. It has a unique color, thermal stability and solubility. These mentioned items make the RPO suitable for being used in molded articles, slippers, LPG tubes, floor tiles, etc.
According to the Rubber Manufacturers Association (RMA) report:
A typical passenger tire weighs about 11.5 kg which contains
1.5 kg of natural rubber
3 kg of synthetic rubber
3 kg black carbon
1.5 kg steel tire cord and bead wire
A truck tire weighs about 54.5 kg which contains
14.5 kg of natural rubber
7.5 kg of synthetic rubber
15 kg of black carbon
7.5 kg steel tire cord and bead wire
