Frequently Asked Questions

Q: What is Trimethylol propane used for?

A: Trimethylol propane is an important fine chemical product, and it is a chain extender commonly used in the resin industry. It has a low melting point and has three methylol groups in its molecular structure. It can react with organic acids to form monoesters or polyesters, react with aldehydes and ketones to form acetals and ketals, and react with diisocyanates to form carbamates. The products are mainly used in the fields of alkyd resin, polyurethane, unsaturated resin, polyester resin, coating, etc., and it can also be used in the synthesis of aviation lubricants, plasticizers, surfactants, wetting agents, explosives, printing inks, etc. It is used as heat stabilizer for textile auxiliaries and polyvinyl chloride resin.

Q: The emergency treatment?

A: Isolate the leaked contaminated area and restrict access. Cut off the fire source. It is recommended that emergency personnel wear dust masks (full face masks) and general work clothes. Mix it with sand, dry lime or soda ash. It need to be collected in dry, clean, covered containers and transfer to a safe place. If a large amount of leakage occurs, collect and recycle or transport to a waste disposal site for disposal.

Q: The characteristics of storage and transport?

  • Precautions for operation:

 Airtight operation, strengthen ventilation. Operators must undergo special training and  abide by the operating procedures strictly. It is recommended that operators wear self-priming filter dust masks. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid contact with oxidizing agents and acids. When handling, load and unload lightly to prevent damage to the package. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may contain hazardous residues.

  • Precautions for storage:

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from oxidants and acids, and should not be stored together. Equipped with the appropriate variety and quantity of fire equipment. Storage areas should be equipped with suitable materials to contain spills. When starting the shipment, there must be a complete package and the loading should be secure. During transportation, it is necessary to ensure that the container does not leak, collapse, fall or be damaged. It is strictly forbidden to mix and transport with oxidants and acids. It should be protected from sun exposure, rain and high temperature during transportation.
