一、Performance and applications：
The “liyang”Brand phenolic plastic produceg by our corporation to GB 1404-95 has a good moldablilty, suitable for general molding and forming processing. The molding power is suitable for use in plastice injectors, featuring good processing performance.The products have a bright and smooth surface, with good mechanical and electrical performance, and resisting to general oils and organic solvents. they can be used to make general components and parts for industrial use, such as various types of industrial electrical switches and their parts, instrument casings, telephone set housing, loom components, automobile parts. The special moisture proof phenolic plastic (moisture proof and salt and proof) is suitable for making electrical appliances and their parts for use in tropical zones.
二、Sizes and types：
The main products are PF2A1、PF2A2、PF2A 4 and plastic injecting powder series.in brown and biack colours.
