The PUR hot-melt laminating machine uses solvent-free and environmentally friendly PUR hot-melt adhesive, which can fit the composite materials required by various markets such as cloth and cloth, cloth and film. The composite product has the characteristics of environmental protection and non-toxicity, good adhesion and softness, high and low temperature resistance, not easily affected by temperature after moisture reaction, durable elasticity, wear resistance, oil resistance, and anti-aging.
Advantages of PUR Hot Melt Laminating Machine
1. The PUR hot melt adhesive used is solvent-free and is an ideal green glue
2. No drying, fast compounding speed and high production efficiency
3. The composite product has good washing fastness, good hand feeling, good air permeability and strong three-dimensional feeling
How does the PUR hot melt laminating machine achieve green environmental protection?
The glue selected is PUR hot melt adhesive, which is solvent-free and one-liquid type. Unlike water-based and solvent-based adhesives, which requires a drying process, there is no environmental pollution and poisoning problems caused by solvents, and it meets environmental protection requirements. There is no residual solvent in the product, no pollution discharge problem in production, energy saving and small floor space.
What is PUR hot melt adhesive?
PUR hot melt adhesive
PUR hot melt adhesive is a moisture curing reactive polyurethane hot melt adhesive. The main component is an isocyanate-terminated polyurethane prepolymer. In the high temperature state after heating, the PUR hot melt adhesive molecules react with the moisture or active hydrogen substances in the air or on the adherend to form a partial cross-linked network structure, which makes the bonding strength, chemical resistance, heat resistance, hydrolysis resistance, etc. The performance is better than the general hot melt adhesive. The adhesiveness and toughness (elasticity) of PUR hot-melt adhesive can be adjusted, and it has the thermoplastic cold-setting properties of ordinary hot-melt adhesives.
How does PUR hot melt laminating machine improve production efficiency?
PUR hot melt adhesive does not contain water and solvents, and does not require drying, so the compounding speed is accelerated. The heat source is oil heat, which heats up quickly and evenly. The independent melting system makes the melting more sufficient and faster.
How does PUR hot melt adhesive save production costs?
Humanized design of the machine, saving operators
PUR hot melt adhesive has good adhesion and low glue consumption
Combined with a small amount of diversified production design, cost saving, digital control system, better operability
How to ensure the product quality of PUR hot melt laminating machine?
Moisture-curing reaction in the process of compounding, irreversible, strong adhesion and good washing fastness
The composite process is fully controlled by linkage, the substrate is not stretched, the weight is light and soft, and the hand feel is good
Dot-shaped mesh gluing, the finished product has good air permeability and strong three-dimensional effect
