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 (4)
Vinyltrimethoxysilane (VTMO)
CAS 2768-02-7
Silanes & Organosilanes
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)
Melting Point: ˆ'97°C Boiling Point: 123°C at 1013 hPa (converted to 101.3 kPa) (760… Density: Specific Density: 0.94 (water = 1)

Vinyltriethoxysilane (VTES)
CAS 78-08-0
Silanes & Organosilanes
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
Silanes & Organosilanes
Moisture-cure systems
Designed for moisture-cure systems; the methoxyethoxy leaving groups tune hydrolysis/cure rate

Dicumyl Peroxide
CAS 80-43-3
Specialty Additives
Crosslinking / Curing
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
Physical Description: White to yellow solid; mp = 39 deg C; Fine fain… Appearance: Pale yellow to white granular solid Boiling Point: 130 °C at 760 mmHg (decomposes)
