CONSTITUTION: A TPO sheet composition comprises 35~45 weight% of partially crosslinked thermoplastic olefin resin, 5~15 weight% of non-crosslinked thermoplastic olefin resin, 10~20 weight% of polypropylene resin, 10~20 weight% of ethylene octene rubber, 10~20 weight% of linear low-density polyethylene resin and 5~10 weight% of inorganic filler. The partially crosslinked thermoplastic olefin resin has a hardness of Shore A 65.
Abstract:
PURPOSE: A modifier for a reactive hot melt adhesive, and the reactive hot melt adhesive including thereof are provided to secure the initial adhesive force and the coherence strength between non-polar materials, and to prevent the generation of volatile organic compounds. CONSTITUTION: A modifier for a reactive hot melt adhesive contains a multi-block copolymer. The multi-block copolymer is obtained by polymerizing a polymer initiator having a hydrophilic segment formed by condense-polymerizing a hydrophilic polymer and 4,4`-azobis(4-cyanopentanoic acid), layered silicate, a vinyl monomer, and a chain transfer agent.
