The main fields are FRP in the field of low-concentration inorganic acids and alkali;

Fourth, such as Fuchen, Fuling, Nobi (the performance is slightly inferior to that of Fuchen and Fuling), etc.

Fifth, many local companies are also producing, such as Wuxi Resin Factory, Shanghai Xinhua Resin Factory, etc., but the output is much smaller.

Emerging vinyl resins: Tianma resin, Tianhe resin, etc. Nowadays, Tianhe's vinyl completely adopts Japan's Showa technology, which is cost-effective and has emerged in the domestic market.
