Technical Datasheet | Supplied by Brüggemann
BRUGGOLEN® P252 by Brüggemann is a synergistic mixture of various nucleating and lubricating substances. It is a very effective crystallization accelerator for thermoplastic polyesters, inducing a very fine and homogenous crystalline structure. It is designed for use in injection molding and extrusion. It offers improved mold release, improved dimensional stability and reduction of post–shrinkage and prevention of stress cracking of finished product. Moreover, it provides improved surface gloss, less streaks and mechanical properties (increase of tensile strength and stiffness). It is suitable for processing by dry blending and compounding on twin screw extrusion machines. It is compatible with polyesters (PET and PBT). Recommended dosage level of BRUGGOLEN® P252 is 0.2-0.5%, depending on the polymer and the desired properties of the finished parts. It has a shelf life of 12 months under (closed, dry, 25°C) conditions.
