PTMEG polyether polyol has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The upstream and downstream associated products of PTMEG polyether polyols will be described in detail below.

upstream products:

1. Propylene: Propylene is one of the important raw materials for PTMEG polyether polyols, and propylene oxide is produced by oxidation.
2. Propylene oxide: Propylene oxide is the direct raw material of PTMEG polyether polyol. PTMEG is prepared by ring-opening polymerization of propylene oxide and tetrahydrofuran.

downstream products:

1. Polyurethane foam: PTMEG polyether polyol is an important raw material for the production of polyurethane foam, which is made by reacting with isocyanate. Polyurethane foam has excellent thermal insulation, sound insulation and seismic performance, and is widely used in construction, home appliances, automobiles and other fields.
2. Elastomers: PTMEG polyether polyols can be used to produce polyurethane elastomers with high tear strength, resilience and wear resistance, and can be used to manufacture tires, tapes, seals and other products.
3. coating: PTMEG polyether polyol can be used as the base resin of the coating, and isocyanate reaction to make polyurethane coating, with excellent weather resistance, gloss retention and decoration.
4. Adhesive: PTMEG polyether polyol can be used to produce polyurethane adhesive, which has high bonding strength and weather resistance, and can be used in construction, automobile, packaging and other fields.

To sum up, PTMEG polyether polyols have a wide range of upstream and downstream related products, involving construction, home appliances, automobiles, packaging and other fields. With the continuous growth of market demand and the continuous advancement of technology, the application field of PTMEG polyether polyols will continue to expand.
