  产品说明     
  Blendex® 338 is an ultra high rubber ABS impact modifier resin, and is based on polybutadiene rubber.   
  Offers superior impact efficiency, especially at low temperatures.    
  Reduces notch sensitivity when alloyed with engineering polymers.    
  Disperses easily.     
  Provides abrasion and chemical resistance to polymers.    
  Provides toughness to PVC sheet, profile, electrical conduit and injection molded applications.   
  Increases the impact strength of recycle PVC and other recyclates.    
  Can be blended with polyurethanes and other polymers for improved performance and economics.   
  Can be used to improve the impact performance of PC, polyesters, and CPVC.
