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)
3-aminopropyltriethoxysilane (APTES)
CAS 919-30-2
Silanes & Organosilanes
Primary amino silane
Classic glass-finish silane: silanol end forms hydrolytically durable Si-O-Si bonds to glass surface silanols while the amine couples to the resin, so the interface resists water attack
Melting Point: -70 °C Boiling Point: 217 °C Density: 0.94 at 25 °C

3-glycidoxypropyltrimethoxysilane (GPTMS)
CAS 2530-83-8
Silanes & Organosilanes
Primary epoxy silane
Epoxy-functional sizing for epoxy/anhydride matrices; the glycidoxy group co-reacts with the resin for a covalently bonded, moisture-resistant glass interface
Vapor Pressure: 0.002

3-Methacryloxypropyltrimethoxysilane
CAS 2530-85-0
Silanes & Organosilanes
Acrylic systems
Methacrylate sizing for unsaturated polyester/vinyl ester glass, copolymerizing into the resin during free-radical cure for wet-strength retention
Boiling Point: 190 °C Density: 1.045 at 25 °C Solubility: Sol in acetone, benzene, ether, methanol, and h…
