Unfilled waxes
The majority of model waxes are a mixture of petroleum-derived waxes (paraffin and micro-crystalline waxes) and resins and additives.
| Paraffin wax | Influences the control of the injection temperature. |
|---|---|
| Microcrystalline wax | Influences the flow, hardness and resistance of model waxes. |
| Selection based on melting point and hardness. | |
| Resins | Assist in mitigating shrinking during solidification. |
| Influence solidity, rigidity, hardness and bonding ability. | |
| Natural (derived from pine, petroleum or tar), or synthetic. | |
| Additives | Vegetable waxes (natural). |
| Polyethylene resins that improve the characteristics and the viscosity. |
Filled waxes
Filled model waxes are a mixture of unfilled waxes and filled waxes, most notably polystyrene or isophthalic acid.
Whether filled or unfilled, model waxes need to meet certain criteria for their:
- thermal conductivity;
- surface appearance;
- hardness;
- ductility;
- ash content;
- softening point;
- injection temperature;
- mechanical resistance;
- dimensional stability;
- viscosity;
- releasability;
- removability;
- compatibility with grout.
