Polyurethane also known as TPU is an elastomer used as raw material in the manufacture of solvent base adhesives for the shoe, automobile and other industries.
They are a crystalline polymer with a structure composed of a rather small portion of hard segments in relation to their soft segment counterpart.
It is its polyol component (soft or amorphous segment) that crystallizes and provides them with crystalline characteristics, resulting in polymers with outstanding toughness and great tensile strength-deformation Another interesting characteristic of these TPU's is their low melting point in the crystalline zones, which allows the polymer to soften at relatively low temperatures in the bonding process with good thermoplasticity and adhesion to the surface, ensuring proper bonding between substrates of different materials.
