PARAFOL 18-97 Features & Benefits
DSC thermogram - melting profile
The kinematic viscosity is the resistance to flow of a fluid under gravity. It is determined by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer.
Density is a measure of how much mass is contained in a given unit volume. The formal definition of density is mass per unit volume. Usually the density is expressed in grams per mL. In general,
density can be changed by changing either the pressure or the temperature. Increasing the pressure will always increase the density of a material. Increasing the temperature generally decreases the density, but there are notable exceptions to this generalization.

Storage & Handling
PARAFOL single cut paraffns are an excellent choice when looking for a phase change material for latent heat storage applications including functional textiles and construction. The performance profile of PARAFOL single cut paraffin is characterized by:
- Sharp melting profiles.
- Adjustable melting points by chain length in the desired temperature range.
- High latent heat of fusion.
- Non-tendency to segregation.
- Chemical inertness.
- Non-corrosiveness to conventional storage and construction material.
- Non-degradation throughout melt/freeze cycles.
- Non-tendency to supercooling.
