METHOD FOR THE VACUUM-SUPPORTED MANUFACTURE OF A PUR/PIR FOAM BODY
The method involves providing a mold which is adjusted for applying a negative pressure to the interior of the mold, where a reaction mixture with an isocyanate-reactive composition and an isocyanate is filled into the mold. The negative pressure is applied on the interior of the mold, so that the n...

description | The method involves providing a mold which is adjusted for applying a negative pressure to the interior of the mold, where a reaction mixture with an isocyanate-reactive composition and an isocyanate is filled into the mold. The negative pressure is applied on the interior of the mold, so that the negative pressure acts on the filled reaction mixture. The negative pressure is applied no latter than time to the interior of the mold. The ratio of the reaction mixture carries greater than or equal to 300. An independent claim is included for a polyurethane or polyisocyanurate-foam body that is an insulation panel. |
