Why It Matters
Lowering compound melt viscosity and improving throughput in highly filled systems by surface-treating fillers (silanes) and adding processing aids that cut filler-filler interaction
Solution Approach
Lowering compound melt viscosity and improving throughput in highly filled systems by surface-treating fillers (silanes) and adding processing aids that cut filler-filler interaction 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)
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
