Thermally Conductive Polymers for Light Emitting Diodes

Xyloy™ M851 Thermoplastic Metal

FOR Injection Molding

Cool Polymers®, the leading manufacturer of thermally conductive plastics, known as CoolPoly®, has introduced Xyloy™ thermoplastic metals. Xyloy thermoplastic metals are lightweight alloys processed on standard injection molding equipment to produce 3-dimensional net shape parts in high volume.

Xyloy grades offer an outstanding combination of mechanical, physical and thermal properties that surpass the performance of plastics and die cast metals. These new materials help solve today's and tomorrow's engineering challenges with a unique balance of strength, stiffness, conductivity and processability.

Xyloy M851 is a high strength

thermoplastic metal for injection molding.

Cool Polymers offers molded parts in Xyloy M851 according to customer solid models and specifications. Please contact us to discuss your requirements.

FOR USE WITH STANDARD PLASTIC INJECTION MOLDING EQUIPMENT, ADDITIONAL PROCESS STEPS ARE NOT REQUIRED.
STRONGER THAN DIECAST, NO POROSITY, TOOLING GUARANTEED FOR THE LIFE OF THE PROGRAM
CAN BE USED WITH EXISTING TOOLING FOR PLASTIC
FASTER CYCLE TIMES THAN PLASTIC MOLDING
TEXTURED FINISHES AVAILABLE, EASILY ACCEPTS STANDARD COATINGS, INCLUDING PLATING AND POWDER COATINGS
