Industrial Grade VAM Applications：
Vinyl Acetate Monomer VAM is widely used in the manufacturing of polyvinyl acetate emulsions, which find applications in adhesives, paints, coatings, and textiles. The copolymerization of VAM chemical with other monomers, such as ethylene, creates ethylene-vinyl acetate (EVA) copolymers, which have excellent flexibility, adhesion properties, and low-temperature resistance. EVA is extensively used in various industries, including footwear, packaging, wire and cable insulation, and solar cell encapsulation, among others.
GHS Hazard Identification
Per the Globally Harmonized System (GHS) classification of VAM:
- Hazard classification: Flammable liquid, Category 2; acute toxicity by inhalation; skin and eye irritation.
- Signal word: Danger. Hazard statements include: highly flammable (H225); harmful if inhaled (H332); causes skin and serious eye irritation (H315/H319).
- Precautionary statements: keep away from heat and ignition sources; wear eye/face protection; avoid breathing vapors or mist.
- Routes of exposure: inhalation, skin contact, eye contact.
- Possible health effects: central nervous system depression, irritation of eyes and respiratory tract, skin dermatitis on prolonged exposure.
- Refer to the Safety Data Sheet (SDS) for the complete hazard and first‑aid information.
Handling and Storage Notes
- Store below recommended temperature and keep inhibitor level within specification to prevent polymerization.
- Keep away from heat, sparks and open flame; the flash point is -8 °C (closed cup).
- Keep containers tightly sealed and protected from oxygen ingress where required.
- Use proper grounding during transfer and follow the SDS.
