PIR foam recycling solution

Do you know what is PIR or PUR foam, and what is the difference between two materials? Polyisocyanurate, also referred to as PIR, polyiso, or ISO, is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. Its chemistry is similar to polyurethane (PUR) except that the proportion of methylene diphenyl diisocyanate (MDI) is higher and a polyester-derived polyol is used in the reaction instead of a polyether polyol. Catalysts and additives used in PIR formulations also differ from those used in PUR.

Many customers from the insulation industry are looking for the solutions to recycle PIR foam, in order to reduce the volume to save the transportation and landfill costs. Recently we did test for 2 pallets of this material using our customized cold compactor FD-3000.

See attached pictures, the average pallet size is:

5ft x 4ft x 4ft = 80 cubic feet/pallet.

Input material:  2 pallets = 80 cubic feet x 2  = 160 cubic feet.

Out put block:  10ft x 10 inch x 10 inch = 6.94 cubic

% reduction:  100% – 6.94/160 = 95.66% volume reduction

Both of our engineer and client are excited about this result, we feel it is a good solution to help insulation panel manufacturers to solve the waste PIR or PUR foam problems.
