Fiber Lubricants
During polyurethane fiber production by the dry and wet spinning processes, WACKER fiber lubricants maintain key properties, such as low friction and reduced fiber breakage, increased efficiency, and much more.WACKER fiber lubricants also prove effective as processing aids for PAN precursor fibers used in carbon fiber production. These finishes are in demand whenever an application requires very high tensile strength and maximum physical resistance under extreme conditions. In the production of PET, PA or PP fibers by melt spinning, special heat-resistant release agents and lubricants are used to significantly reduce fiber breakage while simultaneously increasing the processing rate and minimizing the amount of maintenance work generally required.
Defoaming
Defoaming agents play a key role in optimizing the manufacturing process. WACKER product defoamers effectively combat and prevent the foam normally occurring during processing. SILFOAM® allows foaming in the wet spinning bath during fiber production to be selectively controlled, ensuring that workflows run smoothly. WACKER antifoam agents are especially efficient, largely chemically unreactive, and ensure a high production rate.
