Middle Temperature Hot Melt Adhesive Resin Pellet High Adhesion

Grade:VF790

Product: Hot Melt Adhesive Resin For Aluminum Plastic Panel And Heat Insulation Panel

Descriptions

Traditional hot melts have several limitations; they are temperature sensitive, that is, they soften at elevated temperatures and consequently loose strength and at low temperatures, they become brittle. They are also susceptible to creep which can cause joint failure when exposed to stress. Most hot melt adhesives are applied quite hot at temperatures between 100 to 230°C (212 to 450°F), and therefore, cannot be used on temperature sensitive substrates. Another draw back is the short open time, which is the time before the liquid adhesive solidifies.

VF790 is a maleic anhydride and vinyl acetate functionalized polyethylene mixture, easy to form film, with excellent processability and adhesive strength.
