Special Plastic Composite Ball

Fracturing ball of special plastic composite technology parameters （1） can work in 180 degree water solution for a long time （2） can endure the compressive strength about 80mpa for a long time （3） good performance for acid, alkali, salt and other chemicals resistance （4） high wear resistance, high hardness, high strength and high impact strength （5） low density (about 1.3-1.6 gcm3) （6） no deformation under high pressure and high temperature （7） high degree of finish and good dimensional stability of the ball.
