Poly Foam Soft can be used at 2:1 by weight. This will produce a soft foam. The isocyanate content may be increased in order to obtain firmer foam or decreased for a softer foam. The user must first thoroughly test their chosen ratio before going into production.
Excessive usage of isocyanate can cause hardening of soft foams over time and may even cause excessive contraction of the moulding.

Soft Foam can free rise up to 8x the original mixing volume, the example listed below was a mix ratio of 2:1 totalling 50g (33.33g Part A + 16.67g Part B) in a working environment of 25°C

In lower temperature conditions the free rise ratio will decrease.

Weight to volume ratio: Example 750g Kit

750g Kit Part A is 500g - This equates roughly to 480ml in volume
750g Kit Part B is 250g - This equates roughly to 220ml in volume

750g kit is roughly 700ml in volume, so to mix a full 700ml at once at the correct working temperature of 25C the foam will free rise to roughly 5.6 Litres, but if it is not used in the correct working conditions the free rise ratio will decrease.
