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)
Vinyltrimethoxysilane (VTMO)
CAS 2768-02-7
Silane & Organosilane
PE crosslinking and polyester
Vinyl group grafts onto the PE backbone via peroxide radicals; the three methoxy groups then hydrolyze and condense with ambient moisture to form Si-O-Si crosslinks (Sioplas/Monosil)
Schmelzpunkt:ˆ'97°C Siedepunkt:123°C at 1013 hPa (converted to 101.3 kPa) (760… Dichte:Specific Density: 0.94 (water = 1)

Vinyltriethoxysilane (VTES)
CAS 78-08-0
Silane & Organosilane
Slower hydrolysis vinyl
Slower-hydrolyzing ethoxy analogue giving longer scorch safety/processing window before moisture cure
Vapor Pressure: 2.28

Vinyltris(2-methoxyethoxy)silane (VTMOEO)
CAS 1067-53-4
Silane & Organosilane
Moisture-cure systems
Designed for moisture-cure systems; the methoxyethoxy leaving groups tune hydrolysis/cure rate

Spezialadditive
Vernetzung / Härtung
3110 (DICUMYL PEROXIDE) · Class Free-radical initiator that abstracts H from PE to create the grafting sites where the vinyl silane attaches — the first step of the Sioplas/Monosil mechanism
