　　PPA with fiber ceramic white color is mainly used in the production of LED brackets. Currently, the production of LED brackets mainly uses the 112114 model from Japan's Keleli, which is rare on the market. Most manufacturers are gradually switching to the 112 model PPA. There are few PPA modification manufacturers in China, and good ones include Shanghai Jinfa, Suzhou Taibao, Guangzhou Gangyangda, etc.
