Triethylene glycol (TEG) is an important chemical raw material, which is widely used in various fields. In the field of raw materials for chemical production, the upstream and downstream related products of triethylene glycol driving materials mainly include the following aspects:

upstream products:

1. Ethylene oxide: Ethylene oxide is the main raw material of triethylene glycol. Ethylene glycol can be generated through the hydration reaction of ethylene oxide, and then triethylene glycol can be further generated by further reaction.

downstream products:

1. polyester fiber: triethylene glycol can be used as the raw material of polyester fiber, and dimethyl terephthalate (DMT) ester exchange reaction, the generation of terephthalic acid diethylene glycol ester (BHET), and then through the polycondensation reaction to generate polyester fiber.
2. Unsaturated polyester resin: triethylene glycol can be copolymerized with other unsaturated monomers to produce unsaturated polyester resin, which is widely used in FRP, coatings and other fields.
3. Polyurethane: Triethylene glycol can be used as a raw material for polyurethane, reacting with diisocyanate, chain extender, etc. to generate polyurethane foam, elastomer, etc.
4. cleaning agent: three ethylene glycol has good solubility and cleaning ability, can be used as a cleaning agent for metal processing, mechanical equipment and other fields of cleaning.

To sum up, the upstream and downstream related products of triethylene glycol are very extensive, involving polyester fiber, unsaturated polyester resin, polyurethane, cleaning agent and other fields.
