PO3G polytrimethylene ether glycol
Molecular Weight: 500 – 2700 g/mol
CAS-No.: 345260-48-2
It is an ideal petroleum-derived polyol due to its outstanding properties Alternatives can provide different excellent properties in different fields, and can increase the bio-based content of the final product without affecting its final performance.
With products of petroleum origin such as polytetrahydrofuran, polypropylene glycol, polyethylene glycol In comparison, this product is more friendly to the environment. According to the ISO14000-1 life cycle analysis, it can reduce non-renewable energy consumption by 40% and greenhouse gas emissions by 42%.
PO3G is synthesized from bio-based propylene glycol from renewable seeds.

Varies Application field
（1）High performance polyester elastomer
PO3G is an ideal high-performance polyether polyol, which is used as a substitute for petroleum components in polyurethane, copolyamide and copolyester elastomers. PO3G can easily replace soft-segment polytetrahydrofuran in polyurethane elastomers, and at the same time Offers include good chemical resistance, high strength, softness and resilience.
(2) Functional paint
PO3G can be used as a raw material of polyurethane resin for different coatings such as automotive surface coating and industrial metal coating, and is used to replace petroleum-derived polyols. PO3G provides excellent metal adhesion if used in base paints, excellent color development if used in colored paints, and excellent flex resistance if used as an additive in clear coats and scratch resistance.
(3) Functional fluid
Due to excellent thermal conductivity, thermal stability and lubricity, as well as excellent low temperature performance, low toxicity and biodegradability. PO3G is an ideal base fluid for lubricating oil, cooling liquid and heat exchange.
(4) Clothing and shoe materials
Due to its excellent abrasion resistance, soft feel and moisture permeability (MVTR), PO3G is an excellent raw material for shoe materials, synthetic leather and functional apparel.
(5) Ink
PO3G-based polyurethanes can be added to ink formulations without compromising final functionality while providing unique additional properties. PO3G inks have deep, clear shades and better durability.
