FINEX XLPS FILLERS – ALWAYS ONE STEP FURTHER
SPECIALTY POLYMERS IN INVESTMENT CASTING
Cross-linked polystyrene (Styrene and Divinylbenzene co-polymer) is a common filler used in production of synthetic waxes for the so-called lost wax process as used by the Precision Investment Casting industry. Wax fillers have a major influence on the basic physical properties of the investment casting waxes where it is important to ensure that a good surface finish to the investment is achieved. Large portions of the investment casting waxes in current use contain fillers of different type.
Our XLPS fillers are thermally stable and have a similar density to that of the molten base wax to minimise settlement. Finex XLPS fillers have very low ash contents to minimise the amount of undesirable material left behind in the ceramic shell after de-waxing.
Compared to some other filler materials available, Finex XLPS fillers are safe to use both in terms of personal exposure and environmental impact; XLPS fillers are Bisphenol-A free and the Finex manufacturing method also ensures low volatile content due to residual styrene. Furthermore it is a cost effective solution for the investment casting industry.
We offer different grades of XLPS fillers:
- Finex XLPS Bead, a white translucent bead with a mean particle size of 50 – 90 µm
- Finex XLPS Ground, a white translucent powder, with a mean particle size 50 – 100 µm
Both XLPS Bead and Ground are available with low volatile content. Finex XLPS fillers are packed in big bags (1 m3) containing 600 kg of bead or 500 kg of Ground.
Finex supply XLPS fillers globally to all the main wax producers in the Investment Casting industry.
OTHER INDUSTRIAL APPLICATIONS
Finex XLPS products are used in various applications. Our XLPS products are mainly used as a filler in synthetic wax production for the Investment Casting industry. Other application areas include utilisation of our polymers in adsorbent applications.
