#8 Major Applications of Waste Foam Polyurethane Recycling and Reuse
1: # Waste foam for lightweight partition boardsWaste foam polyurethane particles are mixed with cement, fly ash, additives and water, then cast and cured in vertical or horizontal partition board moulding equipment to be used as internal and external thermal insulation fireproof lightweight partition boards.
2: foam polyurethane lightweight concreteWaste foam polyurethane particles are mixed with cement, fly ash and additives to be used as roof thermal insulation lightweight mortar.
3: foam polyurethane insulation boardWaste foam polyurethane is mixed with new polyurethane black and white materials AB, foamed in a mould, and used as roof insulation board and color steel sandwich panel with outstanding thermal insulation effect and cost reduction.
4: foam polyurethane Grade A fireproof insulation boardUsed as inorganic fireproof insulation layer of integrated insulation and permanent formwork. Grade A fireproof external wall insulation board, roof insulation board, self-insulation aerated block for infill wall.Waste foam polyurethane particles are mixed with cement, fly ash, additives and water, cast and cured in horizontal moulding equipment into insulation blocks of 3m×1.2m×1m.Can be cut into self-insulation aerated blocks 300×600×300;Can be cut into fireproof insulation layer of permanent insulation formwork 3000×1200(600)×50;Can also be cut into internal and external thermal insulation fireproof lightweight partition boards 2900×610×150(100,200,240).
5: # Waste foam polyurethane particle floor sound insulation board, floor heating insulation board, floor heating insulation mortarWaste foam polyurethane particles are mixed with cement, fly ash, additives and water, cast and cured in horizontal moulding equipment into insulation blocks of 3m×1.2m×1m, which can be cut into floor sound insulation boards 3000×600×30.
6: foam polyurethane insulation composite boardWaste foam polyurethane particles are mixed with SPU-F (Waste Foam Liquid King) invented by Zhengzhou Zhongtian for static foaming.Waste polyurethane particles react and re-foam with new flexible raw materials to form boards.Waste polyurethane particles and special liquid foam agent are seamlessly foamed into an integrated board, forming standard-sized B-class flame-retardant polyurethane insulation boards, cuttable freely.Low equipment investment: 300,000 RMB, including 1 liquid foaming machine, 1 moulding machine, 1 cutting saw.Waste foam liquid foaming agent SPU-F: 35,000 RMB/ton, foaming 60–70 m³/ton, 10 kg/m³, cost 583 RMB/m³.Waste polyurethane particles: 75%, new liquid material: 25%.Finished product density after mixing: 40 kg/m³.New material cost: 145 RMB/m³.Applications: external wall insulation board, roof insulation board, color steel sandwich panel, floor sound insulation board, elevator shaft sound insulation board, hotel sound insulation board.
7: wire mesh waste foam polyurethane seamless insulation meshing boardWaste foam polyurethane particles are mixed with SG‑N (Waste Foam Liquid‑Solid King) invented by Zhengzhou Zhongtian for static micro‑foaming.Organic‑inorganic meshing boards are formed by re‑foaming waste polyurethane particles with new liquid‑solid material.With steel wire mesh as framework, waste polyurethane particles and special liquid‑solid agent are seamlessly foamed into an integrated board, forming standard‑sized Grade A fireproof insulation boards.Fire resistance: 3 hours, board density 80 kg/m², size 3000×610×100, 10 boards/minute.Low equipment investment: 1,300,000 RMB, including 1 set of foaming machine, 10 moulding machines.Raw material SG‑N: 600 RMB/ton, foaming 3 m³/ton, 330 kg/m³, cost 200 RMB/m³.Waste polyurethane particles: 75%, new liquid‑solid material: 25%.Finished product density: 80 kg/m².Applications: indoor partition board, external wallboard, fireproof board for pigsties and chicken coops, block infill wall panel. 8: High‑strength waste polyurethane foam extruded boardWaste foam polyurethane particles are compressed into boards by large‑tonnage hydraulic press.
