Polyvinyl Alcohol(PVA)

Oct 24, 2024

Brief Introduction

Polyvinyl alcohol (PVA), is a widely used water-soluble polymer with properties between plastics and rubber. It has unique strong adhesion, film flexibility, oil resistance, surface activity, gas barrier, wear resistance, etc. PVA can undergo typical chemical reactions of polyols and undergo insoluble treatment to give it different functional properties, thereby producing a series of synthetic materials. The rich derivatives produced by it and its wide range of applications make PVA an important polymer organic chemical raw material.

Industrial Chain

The upstream of PVA is the main basic chemical raw material, including coal, acetic acid, vinyl acetate, etc. The downstream is mainly used for the production of PVA fibers, adhesives, textile pulp, PVB, etc. Terminal requirements include synthetic fibers, building adhesives, white latex, glass intermediate films, biodegradable PVA films, etc.

Hazard Identification Information And First Aid Measures

Hazard type First aid measures
Inhalation: Inhalation of large amounts will cause discomfort
Skin contact: No hazard
Eye contact: Slightly irritating
Ingestion: Ingestion of large amounts will cause discomfort
Inhalation of dust: Move to fresh air
Skin contact: Wash with clean water
Eye contact: Wash with clean water
Ingestion: No treatment is required for small amounts, and large amounts of ingestion require hospital treatment
Fire and explosion hazards:
Dust mixed with air may cause explosions, and the explosive force is strong, reaching 1.0-2.0 (US Minerals Administration standard)
Bulk storage should be properly prevented
Package and storage in film bags or paper bags
Spray with water, or use foam, carbon dioxide or dry powder fire extinguishers in case of fire
Environmental hazards:
Dust floating in the air will cause local air quality to deteriorate; it will be dissolved in water when it enters the sewer, producing foam that will cause a slight increase in COD and BOD values; it will not cause obvious harm when it enters the soil
Enhance air circulation and add dust removal devices to air circulation equipment
It has strong biological decomposition ability and generally will not cause long-term pollution, but a large amount of it entering the river may also cause certain harm. Clear the ground and equipment to spread materials, clean the ground and equipment, and install filtering equipment at the outlet
Physical and chemical hazards None
Special hazards None
