Perfect 👍

[@pufoamtoolsandguides]

Much appreciated

[@gilbertmumelo8571]

Why are you not using methylchloride

[@pufoamtoolsandguides]

Because foam density 21, 22, 23, ... is safe to produce without methylene chloride but limited by height of foam block

[@gilbertmumelo8571]

@@pufoamtoolsandguides what effect does it have with the height?

[@gilbertmumelo8571]

Using calcium carbonate reduces the cost of production despite producing less quality product is that true.

[@pufoamtoolsandguides]

@@gilbertmumelo8571 High foam block will not cool fast therefore high exotherm generated will accumulate and lead to scorching in the center of foam block

[@onkyvanderkerkhof]

I want to ask about calculate exothermic
Do you explain this formula calculate exothermic, please?
Where the number come from 69 1.394 and 1.17?
Thanks

[@pufoamtoolsandguides]

Hi, this similar question was answered in the comments section of one of the videos Sir, thanks

[@pufoamtoolsandguides]

They are derived from heat capacities of raw materials and foam mix

Thanks Sir
