Solution Approach
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 Formulation Workflow
1
Polymer & Process Definition
Identify the resin and process (extrusion, molding, film) and the targets — thermal stability, clarity, flame retardance, slip, or color.
2
Additive Selection
Match stabilizers, antioxidants, plasticizers, lubricants, flame retardants, or masterbatch carriers to the polymer and processing temperatures.
3
Compounding Trial
Confirm loading and dispersion on a compounding or molding trial, checking processability, mechanicals, and aesthetics against the control.
4
Validation & Scale-Up
Verify long-term performance (heat aging, migration, weathering) and lock the formulation, packaging, and lot specs for production.
Recommended Chemistries (5)
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: Pellets or crystals or liquid Boiling Point: 383 °C Melting Point: -48 °C

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

Dioctyl Phthalate
CAS 117-81-7
Canonical general-purpose ester plasticizer for polar elastomers (NBR/CR), which are incompatible with petroleum process oils and use DOP in their place as the softener/processing aid — exactly the softening/flow role the page covers; direct parallel to the already-listed DINP phthalate.
