ADHESIVE MATERIAL, PRESSURE SENSITIVE ADHESIVE FILM AND METHOD OF USE THEREOF

摘要

An adhesive material and pressure sensitive adhesive film containing the same, characterized in that they satisfy the following requirements (a) and (b). These adhesive material and pressure sensitive adhesive film exhibit excellent stability against not only light and heat but also various chemicals. Consequently, they find suitable application in surface protection uses, transport storage uses, heat treatment uses, grinding polish uses and cutting working uses in the fields of electronic/semiconductor materials, optical/display materials, etc. wherein demands for performance and quality are strict. The above requirements are: (a) an olefinic polymer is contained, and (b) in the measurement according to differential scanning calorimetry test, the melting temperature (Tm) is in the range of 80 to 180°C while the melting heat (DeltaH) is at least 1 J/g.
