REBOND FOAMING
Rebond foam is obtained using shredded recycled foams with scraps of other foams. The foam scraps are mixed with liquid polyurethane to bind them and then compressed into a block. It has an open cell structure and is known for its firm and durable properties.
SHREDDING
The first step in the rebond foaming is to get shredded the foam flocks out of the trim foam.
A knife shredding type machine is the suitable model for shredding various materials, such as: PU, PE, PVC, EVA, TPR, TPE, PP, PE.
The foam flakes coming out from the shredder are blown into the mixing drum where they are mixed with adhesive. The mixture is dropped into a standard size mold where it is hydraulically pressurized to become rebound foam. The process can be carried out without or with an additional steam system.
RE-BONDING GLUE
STEAM TYPE. Injection steam 80°C - 100°C / 1 block production time 15-20 min.
NON-STEAM TYPE. Water, bonding agent / 1 block production 60-70 min.
ADVANTAGE
Provide excellent adhesion properties with the low dosage.
Save the total production cost by lowering dosage, and shorten the steam time and working time.
No bonding lump inside of the re-bonding block
DOSAGE
8-15 kg per 100 kg foam scrap
