Carrier: PET, PBT, PA 6 • Continuous filament, including fine deniers (POY, FDY, HOY) • Spunbond SINGLE PIGMENT DISPERSIONS (SPDS) We have extensive experience in using advanced technologies and special raw materials, which make these products suitable for sensitive applications. FIBER SOLUTION SERVICES LABORATORY PERFORMANCE BASED ON STATE-OF-THE-ART TECHNOLOGY To ensure the highest quality products, our customers rely on high- performance raw materials which guarantee that the final products meet the required specifications for heat resistance, household washing, weathering and lightfastness. Processing conditions can cause material properties to shift from the values stated in the information.

Steel/chromium alloys (approx. 13% Cr) are the preferred mold material due to their longevity and resistance. Sink marks and warpage are caused by material shrinkage in thick or asymmetric areas during cooling. Processing conditions can cause material properties to shift from the values stated in the information.

Precautions: the extruder should not be idle with the material in the hot barrel. Processing conditions can cause material properties to shift from the values stated in the information. Processing conditions can cause material properties to shift from the values stated in the information.

Plastisols will most likely change over time and material should be used on a first-in-first-out (FIFO) basis as quickly as possible. Processing conditions can cause material properties to shift from the values stated in the information. Stirring should be done gently so as not to introduce air or heat into the plastisol, but forceful enough to re-disperse any settled material on the bottom.
