Non-polar plasticizers are often used in rubber applications that require low-temperature flexibility and resistance to oil, solvents, and other non-polar substances. Here are some common non-polar plasticizers used for rubber:

1. Mineral oil – Mineral oil is a commonly used non-polar plasticizer that provides good low-temperature flexibility and excellent resistance to oils and solvents. It is often used in automotive and industrial applications.
2. Paraffin wax – Paraffin wax is a low-cost plasticizer that provides excellent low-temperature flexibility and good resistance to oils and solvents. It is often used in cable insulation and other electrical applications.
3. Naphthenic oil – Naphthenic oil is a non-polar plasticizer that provides good low-temperature flexibility and excellent resistance to oils, solvents, and other non-polar substances. It is often used in automotive and industrial applications.
4. Terephthalic acid esters – Terephthalic acid esters are non-polar plasticizers that provide good low-temperature flexibility and excellent resistance to oils and solvents. They are often used in automotive and wire and cable applications.
5. Chlorinated paraffin – Chlorinated paraffin is a non-polar plasticizer that provides good low-temperature flexibility and excellent resistance to oils, solvents, and other non-polar substances. It is often used in wire and cable insulation and other industrial applications.
