Application:
The properties of G-510p make it suitable for the production of light and heavy insulation board by block or shape molding.
Processing
The processing conditions of G-510p 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 densities below 15 kg/m3 , batch prefoamer is recommended and with a continuous prefoamer prefoaming twice. To reach higher densities (>25 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. When prefoaming in two steps, a conditioning time of 4–6 hours between the first and the second step is optimal but can be a bit longer.
- Molding: The machine should be fed with saturated steam with a max pressure of about 2 bar. 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
G-510p 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 G-510p 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
G-510p 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.
