Global high-performance polymers company Covestro recently announced the delivery of its first commercial order of polyurethane raw materials designed for wind blades to China, one of the leading markets for wind power in the world.

The blades were produced by wind blade manufacturer Zhuzhou Times New Material Technology, and were recently delivered to wind turbine technology firm Envision.

According to Covestro, the resin was to go toward the production of 18 59.5-meter-long (roughly 195-foot-long) polyurethane blades, as well as for spar caps and shear webs. The company’s wind power team developed a prototype, put in place at a Central China wind farm in 2018, to undergo (and pass) static and fatigue tests.


Polymer materials supplier Covestro (Pittsburgh) recently announced the delivery of its first commercial order of polyurethane raw materials, designed for wind blades. The order went to China, one of the leading markets for wind power in the world.

“We are very excited to be working with Envision and TMT on this first sales order of PU wind blades in China. Polyurethane resin in the production of wind blades, is a game-changing innovation delivered by Covestro teams around the world,” said Ulrich Liman, Global Head of R&D, Business Unit Polyurethanes at Covestro.

“We remain committed to our vision of creating products that benefit society and improve people’s lives all over the world.”

The use of polyurethane resin in manufacturing large-scale rotor blades for wind turbines provides a number of benefits, including faster curing time and better processing opportunities.

In October 2018, the company announced the operation of the first wind turbines with blades made from the company’s polyurethane infusion resin. This announcement marked the company’s latest benchmark in its mission to commercialize polyurethane infusion resin for the wind power industry.

The blades are slated to be installed on an East China wind farm by next month.

Go ahead good people! Export your raw material to Chine but don't cry in few years if you do not have no one to Buy your polyuréthane rein! The Cinese will copy it and produce it by themselves! Shortseeing people in Covesto looking for very short term profits!!!
