Grade:VF790
Product: Hot Melt Adhesive Resin For Aluminum Plastic Panel And Heat Insulation Panel
Descriptions
Hot melts are formulated with numerous thermoplastics, including ethyl vinyl acetate (EVA) for general purpose bonding, polyolefins for difficult-to-bond plastics, styrene block copolymers (SBC) for good low temperature flexibility, high elongation and improved heat resistance, polyamides for severe environments, and reactive urethanes and silicones for elevated temperature and/or high flexibility requirements. These thermoplastics are typically blended with a variety of other raw materials including tackifying resins, waxes, plasticizers, oils, fillers, and antioxidants, which are incorporated into the base hot melt resins to enhance adhesive performance. Natural or synthetic tackifiers are usually added to some formulations to alter or improve adhesion (tack), surface wetting, open time, and polymer flexibility of the adhesive. Waxes help to reduce pellet blocking, and reduce melt viscosity, and/or enhance the tack of the adhesive. Antioxidants are used to prevent/minimize oxidation and decomposition of the hot melt during service and during processing and to improve storage stability.
VF790 is a maleic anhydride and vinyl acetate functionalized polyethylene mixture, easy to form film, with excellent processability and adhesive strength.
