Laminations using gum rubbers, foams, urethanes, etc
Lamination is a value-added option that can be customized to help improve product performance. Cured rubber, rubber belting or belting and rubber in various combinations can be vulcanized or bonded together to create thick pads and blocks. Laminations using gum rubbers, foams, urethanes, etc. are performed daily.
Beltservice's Special Fabrications Department can laminate or bond any belt in our inventory of over 300 specifications to a wide range of materials. To create a lamination, two or more different materials are bonded together using adhesive cements in combination with either low heat, high heat, or no heat.
Some of the materials that can be laminated include Linatex®, pure gum rubber, skirtboard rubber, foams, sponges, fabrics, metals, and other conveyor belts. The materials are prepared with a buffed or sanded surface, cement is applied to both pieces and they are bonded together.
One concern in the bonding process is trapped pockets of air between the materials being laminated. Care is taken to apply even pressure to remove the air before bonding is completed. Depending on the type of cement and the materials, the lamination may be moved to a press for heat curing. Foam and sponge-backed belts use a cold bond process. Every material is different and requires different procedures.
Applications include: belts for pulling or traction, chute liners, drive belts, and railcar liners & cushions.
