Powder blowing agents can cause dusting and be difficult to handle or meter efficiently at the typical loadings of less than 1 %. The FICEL® liquid and pellet forms help to assist in convenient and dust-free handling without the need for personal respiratory protection or expensive dust extraction equipment. Furthermore, the pellet masterbatch product can be added and dispersed with the polymer by tumble blending or direct metering on standard equipment. The liquid forms can be added directly to the extruder feeder, or readily mixed into a vinyl plastisol. All of these benefits help to improve the working environment and minimize the capital investment for the safe and effective use of these products
