PUR hot melt glue coating composite machine is widely used in textile, clothing, furniture, automotive interior decoration, packaging and other fabric composite process.
PUR adhesive is a molecular structure containing polarity and chemical activity of ammonia ester or isocyanate based, and contains active hydrogen materials, such as leather, fabric, paper and other porous materials and plastic surface smooth materials have excellent adhesion, and EVA Hot Melt Adhesive, water-based solvent adhesive compared, PUR has the following advantages:
1.No solvent, no drying process, no solvent existing environmental pollution and poisoning problems, to meet the requirements of environmental protection, simple bonding process, using roll coating or spraying sizing methods, comprehensive design of different styles of PUR hot melt glue coating composite machine.
2.PUR hot melt glue coating composite machine simple operation, good control, fast composite speed.
3.PUR hot melt glue coating composite machination products: heat resistance, cold resistance, water vapor resistance, chemical resistance and solvent resistance is excellent, compared with the original hot melt glue, due to the reaction type of hot melt glue crosslinking structure performance and bonding strength is greatly improved.
