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)
BHT (Butylated Hydroxytoluene), Food Grade
CAS 128-37-0
Specialty Additives
Primary phenolic antioxidant
Hindered-phenol primary antioxidant: donates a phenolic H to quench peroxy radicals, breaking the autoxidation chain during melt processing; the legitimate polyolefin AO of this set
Melting Point: 69–71 °C Boiling Point: 265 °C at 760 mmHg Density: 1.048 at 20 °C

TBHQ (Tert-Butylhydroquinone), Food Grade
CAS 1948-33-0
Specialty Additives
Tertiary butylhydroquinone
Hindered hydroquinone radical scavenger, a secondary phenolic option where BHT volatility is a concern
Melting Point: 127–129 °C Boiling Point: 295 °C at 760 mmHg Density: 1.05

BHA (Butylated Hydroxyanisole), Food Grade
CAS 25013-16-5
Specialty Additives
Preservation
Phenolic chain-breaking antioxidant that interrupts peroxide-radical propagation (food-grade stock)
Melting Point: 48–55 °C Boiling Point: 264–270 °C at 733 mmHg Solubility: < 1 mg/mL at 18 °C

Mixed Tocopherols Oil (Natural Antioxidant)
CAS 10191-41-0
Specialty Additives
Preservation
Natural-source phenolic H-donor for radical termination where a non-synthetic stabilizer is required
Melting Point: 2.5-3.5 °C Boiling Point: BP: 200-220 °C at 0.1 mmHg Density: 0.950 at 25 °C/4 °C
