These application scenarios pose diverse performance requirements for UV tapes, including but not limited to wear resistance, scratch resistance, environmental adaptability, electrical safety, and ease of operation.
[0003] The surface materials of traditional UV tapes are mostly single polymers, with limited hardness and wear resistance. When in frequent contact, friction, or accidental scratching, surface damage is likely to occur, which not only affects the appearance but may also reduce the adhesion performance and overall service life of the tape. In environments with humidity, dust, or corrosive chemical substances, the performance of traditional UV tapes is easily affected, such as moisture absorption and swelling, adhesion force reduction, or even being eroded and damaged by chemical substances, resulting in the failure of their functions and being unable to meet the requirements of complex and changeable working environments. In applications such as electronic device assembly and automobile interior fixing, the tape needs to withstand a certain amount of mechanical stress. Traditional tapes lack effective shock absorption and buffering designs and are prone to deformation or internal damage when stressed, affecting the stability and safety of the attached objects.
