BYK® -P 4100

BYK®-P 4100 by BYK is a surface-active processing additive for filled, thermoplastic compounds and for PVC plastisols & calendar applications. It offers reduced torque during compounding and improved printability. The output capacity & the melt volume rate (MVR) are increased with the increase in tensile strength, E-modulus and notch impact strength in the finished part. It is especially recommended for mineral fillers, flame retardants & wood-plastic composites (WPC) and glass fibers HMC. In PVC plastisols, it has very good release properties from gelling drums, release papers, flat screens and molds. It also influences the cell structure of chemically blown foams and improves resilience and increases air permeability. In PVC calendar applications, it has very good release properties during the processing of soft, semi-rigid and rigid PVCs. The recommended level is 0.25-2% additive (as supplied) based upon the filler. For PVC applications, the recommended level is 0.1-3% additive (as supplied) based on the total formulation. The shelf life of BYK®-P 4100 is 36 months.
