XLPS Copolymer Advantages
Superior thermal conductivity results in shorter dwell times and improved productivity.
Fine particle size distribution results in an exceptionally smooth surface finish.
Physically stable with high melting point so that it does not melt into wax matrix.
Low ash content for cleaner shells after burnout.
Environmentally acceptable.
Does not affect the compatibility of the wax with alloys used in investment casting foundries.
Applications
Due to wax handling methods during melting, the conditioning and injection stages of pre-pattern production will directly reflect the quality of the wax pattern produced. Organic fillers are now widely recognized to improve the formulation of investment casting wax. Aldex XLPS Copolymer meets these important criteria as an additive to investment casting wax:
Organic
Low ash content
Relatively high melting point
Fine particle size distribution
Non-reactive towards base wax
Specific gravity close to the base wax
