Abordagem de solução
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 (9)
3-glycidoxypropyltrimethoxysilane (GPTMS)
CAS 2530-83-8
Silanos e Organossilanos
Primary epoxy silane
Epoxy silane couples mineral filler to epoxy/anhydride thermoset; the glycidoxy group reacts into the resin network while silanols bond the filler, raising strength and cutting viscosity
Vapor Pressure: 0.002

3-aminopropyltrimethoxysilane
CAS 13822-56-5
Silanos e Organossilanos
Methoxy amino silane
Trimethoxy (faster-hydrolyzing) analog of the already-listed APTES; primary amine bonds mineral filler into the amine/epoxide-cured epoxy and anhydride thermosets explicitly named on the page. Same role, same problem.

Vinyltris(2-Methoxyethoxy)Silane
CAS 1067-53-4
Silanos e Organossilanos
Moisture-cure systems
A-172 vinyl coupling agent; vinyl group radical-copolymerizes into the styrene crosslink of the peroxide-cured unsaturated polyester and vinyl ester resins named on the page, coupling mineral fillers in exactly those in-scope systems.

Viniltrimetoxissilano
CAS 2768-02-7
Silanos e Organossilanos
PE crosslinking and polyester
A-171 vinyl silane; radical-copolymerizes with the unsaturated polyester / vinyl ester matrix during peroxide cure to bond treated mineral filler. Page names both polyester and vinyl ester, so scoped to filler coupling here it is a genuine fit (distinct from its PE-crosslinking use, which is a different page).

3-(2-Aminoethylamino)propyltrimethoxysilane
CAS 1760-24-3
Silanos e Organossilanos
Enhanced adhesion
DAMO / A-1120 / Z-6020 diamino silane; two reactive amines give stronger filler-to-resin coupling in the epoxy and anhydride thermosets on the page versus monoamino silanes. Genuine same-use complement to APTES.
Physical Description: Light yellow liquid Vapor Pressure: 0.03

3-glycidoxypropyl methyldiethoxy silane
CAS 2897-60-1
Monoalkyl epoxy silane
Epoxy-functional coupling agent; glycidoxy reacts into the epoxy/anhydride matrix on the page, and the methyl (difunctional) substituent deliberately builds a lower-crosslink, more flexible filler interphase. Documented coupling-agent use, complementary to the listed trifunctional GPTMS/GPTES.
