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 (4)
Hydrophobic Modified Fumed Silica
CAS 68909-20-6
Silanes & Organosilanes
Treated silica for non-polar systems
Silane-hydrophobized filler surface reduces inter-particle hydrogen bonding and structure, so the filled melt flows at lower viscosity for the same loading

Methyltrimethoxysilane
CAS 1185-55-3
Silanes & Organosilanes
Film Formation
Non-functional alkyl silane that caps filler silanols to lower surface energy and filler-filler attraction, cutting compound viscosity (slug corrected: it is a methyl alkyl silane, not an amino silane)

Calcium Stearate
CAS 1592-23-0
Esters
Surfactancy
Metal-soap processing aid that coats filler and lubricates flow, reducing torque and viscosity during compounding
Physical Description: Pellets or Large Crystals, Liquid, Other Solid;… Appearance: FINE, WHITE TO YELLOWISH WHITE, BULKY POWDER Melting Point: Melting point equals 217 ° F
