Wanhua Chemical Polyol Strategic Business Unit
Wanhua Chemical Group sets up Polyol SBU in April, 2015, by combining Wanhua Rongwei founded in 2008 and flexible polyol founded in 2016 in Bajiao industrial park.

Wanhua Rongwei mainly supplies the rigid polyol, CASE polyol and blended polyol. It consists of 3 plants, one is in Yantai (North China), one is in Foshan (South China) and one is in Ningbo (East China), with the total production capacity as 200KT of base polyol and 200KT of blended polyol. Its products include 17 series, over 100 grades, widely applied in many areas, such as household appliance, panel, imitating-wood, pipe, cold chain, auto, spray coating, coal reinforcement, etc.

The flexible polyol in Yantai industrial park mainly produces flexible polyol for slabstock foam, high-resilience foam(HR) and POP with production capacity of 200KT. Products are widely used to produce slabstock foam of different densities and mold HR foam.

Wanhua Chemical Polyol SBU has been aiming to be the leader in domestic polyol industry, to improve the global market influence, and to become the most reliable chemical raw material supplier&service provider.
