Why It Matters
Blown- and cast-film converters add fatty-amide slip agents to lower the film's coefficient of friction and antiblock fillers to stop layers fusing on the roll. Buyers pick erucamide for low-migration slip, oleamide for fast bloom, and silica or talc for antiblock, sourced by the bag and supersack
Solution Approach
Blown- and cast-film converters add fatty-amide slip agents to lower the film's coefficient of friction and antiblock fillers to stop layers fusing on the roll. Buyers pick erucamide for low-migration slip, oleamide for fast bloom, and silica or talc for antiblock, sourced by the bag and supersack 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 Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (5)
Oleamide
CAS 301-02-0
Amines & Amides
Slip / Release
Unsaturated primary fatty amide; blooms quickly to the film surface forming a lubricating monolayer that sharply cuts coefficient of friction
Melting Point: 76 °C Density: 0.94 Solubility: INSOL IN WATER; SOL IN ETHER, HOT ALCOHOL
Full Details
Erucamide
CAS 112-84-5
C22 mono-unsaturated amide; slower, lower-migration bloom gives durable slip with minimal haze, preferred for food and clarity-critical packaging (source on demand)
Full Details
Ethylene bis-stearamide (EBS)
CAS 110-30-5
Bis-amide internal lubricant; reduces melt friction and acts as a secondary slip and dispersion aid (source on demand)
Full Details
Synthetic amorphous silica
CAS 7631-86-9
Specialty Additives
Matting and anti-blocking
Antiblock filler; micron-scale particles create surface micro-roughness that physically spaces film layers to prevent blocking (source on demand)
Melting Point: 1710 °C Boiling Point: 2230 °C at 760 mmHg Density: 2.2
Full Details
Talc
CAS 14807-96-6
Mineral Fillers & Pigments
Conditioning
Plate-shaped mineral antiblock alternative that separates film layers at lower cost (source on demand)
Melting Point: 927–982 °C Density: 2.7 to 2.8 Solubility: < 1 mg/mL at 21 °C
