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 (3)
Mercaptopropyltrimethoxysilane (MPTMS)
CAS 4420-74-0
Silanes & Organosilanes
Mercapto silane for rubber
Methoxysilane end bonds the metal oxide surface while the thiol couples into the sulfur-cured rubber, forming a covalent metal-to-rubber bridge that resists peel (slug corrected: a mercapto silane, not an amino silane)

3-aminopropyltriethoxysilane (APTES)
CAS 919-30-2
Silanes & Organosilanes
Primary amino silane
Aminosilane primer that anchors to metal hydroxides and presents an amine to react with the rubber/adhesive layer
Melting Point: -70 °C Boiling Point: 217 °C Density: 0.94 at 25 °C
