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.
