Polyurethane Thermal-conductive Structural Adhesives are a groundbreaking solution in the realm of bonding materials. These adhesives are not only known for their superior bonding strength but also their exceptional thermal conductivity. This unique feature makes them ideal for applications that require efficient heat dissipation, such as in the electronics and automotive industries. The polyurethane composition ensures durability and resistance to environmental stress, providing a reliable and long-lasting bond. Whether you're dealing with heat-sensitive components or demanding industrial applications, these adhesives deliver high performance and reliability.

Beijing Surterk is dedicated to researching and developing new polyurethane adhesive materials for new energy batteries. We are committed to improving the energy density, safety, cycle life, and lightweight of power batteries. These adhesives are mainly designed based on two major demand points: the first type is structural adhesive, which is mainly for structural bonding, taking into account a certain degree of thermal conductivity; the second type of thermally conductive adhesive, that is, thermal conductive bonding is the main part of the functional role of the realization of thermal management, taking into account the structural bonding requirements.
