Fire prevention measures for propylene glycol methyl ether

Propylene glycol ether and ethylene glycol ether are both glycol ether solvents. Propylene glycol ether is less toxic to the human body than ethylene glycol ether products and is a low-toxic ether. Propylene glycol methyl ether has a faint ether smell but no strong pungent smell, making it more widely used and safer. Since its molecular structure contains both ether groups and hydroxyl groups, it has excellent solubility, suitable volatilization rate and reactivity, and has been widely used.

Fire prevention measures for propylene glycol methyl ether:

Store in a low-temperature, dry place with good air circulation, away from places with possible fire hazards. Rather choose to store outdoors or in a place where it is not affected by others, and separate from things that are not suitable for storage. Containers should be connected and grounded to avoid sparks caused by static electricity. Smoking should be prohibited where this product is stored and used. Use tools and equipment that do not produce sparks. Empty drums that have been filled with this product may also be dangerous because these containers still contain product residues (vapor, liquid). Check all warning labels posted on the drums of this product.

Extinguishing media: dry powder compound, foam or carbon dioxide. Extinguishing the fire with water may not be effective. Spraying water can cool a burning container and dilute the spill into a less flammable mixture to protect the safety of those trying to stop the leak and the spread of vapors.

Special fire protection information: In case of fire, wear protective clothing. Wear assisted breathing apparatus with a protective mask that may operate at a certain pressure or other defined pressure mode.

Propylene glycol methyl ether is mainly used as an excellent solvent for nitrocellulose, alkyd resin and maleic anhydride-modified phenolic resin, and as an additive for jet fuel antifreeze and brake fluid; it is mainly used as Solvent, dispersant and diluent, also used as fuel antifreeze, extraction agent, etc.

Uses: Tetrapropylene glycol methyl ether (107-98-2) is mainly used as an excellent solvent for nitrocellulose, alkyd resin and maleic anhydride-modified phenolic resin; used as jet vinyl antifreeze and Additive for brake fluids; used as a solvent for inks, textile dyes, and textile oils; water-based coatings made from it are widely used in the automotive industry.

Uses Pentapropylene glycol methyl ether (107-98-2) is widely used in coatings and cleaners. Specific applications as reactive solvents for water-based coatings; reactive solvents and coupling agents for solvent-based printing inks; solvents for ballpoint pen and fountain pen inks; coupling agents and solvents for household and industrial cleaners, rust removers and hard surface cleaners; Solvent for agricultural pesticides; used in glass cleaner formulations when mixed with propylene glycol n-butyl ether.

Usage 6: Used as solvent; dispersant or diluent in coating, ink, printing and dyeing, pesticide, cellulose, acrylate and other industries. It can also be used as fuel antifreeze; cleaning agent; extraction agent; nonferrous metal mineral processing agent, etc. It can also be used as raw material for organic synthesis.

Flash point: 32℃ (90F) CC

Burning limit in air (volume percentage)

Lower limit: 1.6 Upper limit: 13.8

Explosion: A mixture of vapor and air explodes when the temperature is above the flash point and within the combustion limits mentioned above. Vapors can travel to the surface of the burning object and the flame will flash back.

Extinguishing media: dry powder compound, foam or carbon dioxide. Extinguishing the fire with water may not be effective. Spraying water can cool a burning container and dilute the spill into a less flammable mixture to protect the safety of those trying to stop the leak and the spread of vapors.

Storage method: Store in a low temperature, dry place with good air circulation, away from places with possible fire hazards. Rather choose to store outdoors or in a place where it is not affected by others, and separate from things that are not suitable for storage.
