About Swisses – Halogen-Free Phosphonate & Phosphate Specialist
Swisses develops, manufactures and markets a full line of
phosphonate / phosphate functional low-viscosity compounds for
halogen-free fire-proof applications.
Our product portfolio is engineered around five core advantages:
| Advantage | Description |
| Low Viscosity | Liquid monomers at room temperature; easy to handle, blend and process without solvents |
| High Phosphorus Content | Efficient flame retardancy at low loading levels; maximises P-content per unit weight |
| Halogen-Free | Fully compliant with RoHS, REACH and IEC 61249-2-21; no toxic halogenated combustion by-products |
| Thermal Stability | High decomposition temperatures (>200–470 °C); suitable for high-temperature processing and end-use environments |
| Hydrolytic Stability | Resistant to hydrolysis under humid conditions; maintains performance in waterborne and outdoor applications |
| Low Dielectric Constant | Ideal for PCB laminates, electronic encapsulants and high-frequency communication materials |
| Reactive Functionality | Vinyl / acrylate groups allow covalent incorporation into polymer networks; eliminates migration and leaching |
