Why It Matters
Choosing extender oils and plasticizers to soften and process rubber compounds. The design's headline is naphthenic/paraffinic petroleum extender oils; the spine carries plasticizer-type softeners instead, which cover the softening/flow role but are not bulk petroleum extender oils
Solution Approach
Choosing extender oils and plasticizers to soften and process rubber compounds. The design's headline is naphthenic/paraffinic petroleum extender oils; the spine carries plasticizer-type softeners instead, which cover the softening/flow role but are not bulk petroleum extender oils RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (4)
Epoxidized Soybean (ESBO)
CAS 8013-07-8
Specialty Additives
Emolliency
Bio-based plasticizer/co-stabilizer genuinely used in elastomer compounds: it softens the compound, eases processing, and scavenges acid; the closest real softening match to a process oil in the spine

Dioctyl Terephthalate (DOTP)
CAS 6422-86-2
Specialty Additives
Plasticizing
Non-phthalate (ortho-free) plasticizer that inserts between chains to lower compound hardness/viscosity for softening — a plasticizer-type softener, not a petroleum extender oil
Physical Description: NKRA; Pellets or Large Crystals; Liquid Boiling Point: 383 °C Melting Point: -48 °C
Full Details
Diisononyl Phthalate (DINP)
CAS 28553-12-0
Specialty Additives
Lubrication
General-purpose plasticizer that lowers compound viscosity/hardness and eases processing; a softening adjunct rather than a bulk extender oil
Physical Description: Di-isononyl phthalate is an oily colorless liqu… Appearance: Colorless liquid Boiling Point: 78 °C at 760 mmHg

Paraffin Wax
CAS 8002-74-2
Specialty Additives
Surfactancy
Legitimate rubber processing/lubricating wax and physical antiozonant carrier that aids flow and surface bloom in rubber compounds
