The Use Of Solvent-free Polyurethane Adhesives Can Significantly Reduce The Production Costs Of Composite Films
Aug 30, 2017

The use of solvent-free polyurethane adhesives can significantly reduce the production costs of composite films, mainly in the following areas:

(1) Solvent-free composite equipment for dry-type composite membrane equipment, save a large complex heating blast, exhaust gas exhaust device, simple equipment, small footprint, province raw materials, low maintenance costs, low-cost investment.

(2) in the process of compounding, it is not necessary to eliminate the organic solvents in the adhesive, and the energy saving is remarkable.

(3) Less glue per unit area (just 1.5~2.0g/m2), low cost of adhesives. Solvent-free composite unit area of about two-fifths of the amount of plastic, so although the solvent-free composite adhesives may be more than the price of dry composite adhesives 70%, but the solvent-free composite unit area adhesive consumption costs less than 30% of dry-type composite low.

(4) The speed of production line is obviously improved. No solvent composite maximum speed can reach 480m/min, generally also in 200m/min above.

Based on the above reasons, the production and processing cost of solvent-free composite is much lower than that of dry-type composite process, about 50% or less.

If the next 10-20 years, China's solvent-free composite technology in the composite market share of the ratio can be as foreign to reach $number, solvent-free adhesives bring economic and social benefits will be enormous.
