Application
The properties of NF-654e make it suitable for the production of flame retardant thin-walled shapemoulded products and heavy insulation board by block molding in accordance with ISO EN 11925-2 class E.
Processing
The processing conditions of NF-654e depend on the combination of the product and processing equipment used. Optimal settings have to be adjusted for each combination.
Some general processing conditions are given below:
- Prefoaming: The steam has to be saturated at a temperature of 100–110 °C. To reach higher densities (>30 kg/m3) it is recommended to mix the steam with air.
- Conditioning: Depends on the density. The higher the density the longer the conditioning time. Generally 12–24 hours is recommended.
- Molding: The machine should be fed with saturated steam with a max pressure of about 2 bar.
- The steaming time depends on the equipment used as well as the size and required strength of the final product. Therefore, all machines have to be adjusted individually. Equipment using vacuum is recommended to reduce cycle times and to increase product strength.
- Cutting: Hot wire cutting (oscillating or stationary wires) is recommended. Temperature of the wires should be about 200–300 °C.
Recycling
NF-654e is suitable for recycling using modern methods of grinding, cleaning and regranulation. In-house production waste should be kept clean to facilitate direct recycling.

Safety & Health
- Safety
In transport NF-654e is classified according to European regulations for product transport: Substance number UN2211, Class 9.
In processing avoid generating dust. All equipment should be properly earthen. Releases pentane during processing which might form a flammable/explosive vapor-air mixture. Use proper ventilation and keep away from any source of ignition.
Packaging & Availability
- Packaging Type
Storage & Handling
- Storage & Handling
NF-654e should be stored at below 20 °C. Protect from direct sunlight and other weather conditions (rain, wind, frost etc.). Keep away from any source of ignition. The storage time should not exceed three months. After opening of the packaging, it should be used as soon as possible.
