DESCRIPTION

Ethylene Bis Stearamide is a high-melting, wax-like solid typically supplied as pellets, flakes, or powder, and Ethylene Bis Stearamide is produced from stearic acid and ethylenediamine chemistry.
Ethylene Bis Stearamide functions by reducing friction at polymer interfaces and by migrating to surfaces to provide slip and anti-block behavior in many thermoplastics.
Ethylene Bis Stearamide can improve dispersion of pigments and fillers by acting as a wetting and lubricating aid during compounding and mixing.

Ethylene Bis Stearamide is compatible with many polyolefins and engineering resins, but Ethylene Bis Stearamide performance depends on dosage, processing temperature, and polymer polarity.
Ethylene Bis Stearamide can influence surface appearance, paintability, and bonding in some applications, so downstream compatibility testing is recommended.
Ethylene Bis Stearamide is often used in combination with metal stearates, fatty acids, and other waxes to tune lubrication balance and processing performance.

Ethylene Bis Stearamide should be stored in cool, dry conditions away from direct heat to prevent agglomeration and to maintain free-flowing handling.
Ethylene Bis Stearamide dust can be combustible in certain conditions, so dust control and good housekeeping are recommended in powder handling areas.
Ethylene Bis Stearamide should be handled with appropriate PPE to avoid dust inhalation and repeated skin contact during industrial use.

FIRST AID

Inhalation:
Move to fresh air if dust is inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing dust during handling and powder transfer.

Skin Contact:
Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a large amount is swallowed.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care based on exposure route and symptoms.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses, and use dust protection as needed for powders.
Avoid generating dust and avoid inhalation of fine particles.
Wash hands after handling and before eating, drinking, or smoking.

Ventilation:
Use local exhaust or general ventilation where dust may be generated.
Maintain good airflow during weighing, charging, and mixing operations.
Minimize airborne dust accumulation in enclosed areas.

Storage:
Store in tightly closed containers in a cool, dry place away from direct heat and sunlight.
Protect from moisture and contamination to maintain product cleanliness and free-flowing behavior.
Keep containers properly labeled and protected from physical damage.

Spill and Leak Procedures:
Sweep up spilled material and avoid dust generation, or vacuum using suitable industrial equipment.
Place collected material into suitable containers for disposal according to local regulations.
Clean residue to prevent slip hazards, especially if pellets or flakes are present on floors.

Handling Precautions:
Control dust and prevent ignition sources in powder handling areas because fine organic dust can present explosion hazards.
Optimize dosage to balance slip and anti-block performance against potential effects on bonding or printability.
Rotate stock using FIFO practices to maintain consistent quality and predictable processing performance.
