Transparent matte PET film, matte PET polyester film-film supplier
The thermosetting hard polymer in the PET high temperature tape causes poor flexibility due to chain separation. The cross-linked three-dimensional network structure is not easy to deform under tension and can withstand higher loads. Thermoplastic polymers are not crosslinked due to the separation of interesting points. Under the action of external force, the chain deforms greatly, and the relative point of interest moves slowly, which causes creep. Among them, the aspect ratio is higher than that of the thermosetting polymer, but the load it can bear is not high; because the high temperature tape elastomer material contains many flexible parts, it is easy to produce reversible deformation under the action of external force. The creep of the thermoplastic and the elastic deformation of the elastomer under the action of a certain shear stress reduce the stress concentration of the sample to a certain extent, and reduce the linear force on the edge of the joint of the sample. Low-molecular-weight thermoplastic resins and polyethylene polymer adhesives have a higher deformation rate under the action of external force, will not break, but can withstand lower loads.
