Description

technical field

[0001] The invention relates to a PVDF composition and a film prepared therefrom, more specifically to a PVDF / PETG composition and a film prepared therefrom. Background technique

[0002] PVDF (polyvinylidene fluoride) is used to protect objects or materials due to its good weather resistance, chemical resistance, high temperature resistance and excellent radiation resistance. In addition, PVDF not only has a glossy appearance but also has excellent scratch resistance. Therefore, people cover various types of substrates with PVDF films. Films made of polyvinylidene fluoride can be used as films for the automotive industry, films for capacitors, anti-atmospheric films, pyroelectric and piezoelectric films, and cover films for solar collector panels. Polyvinylidene fluoride film is characterized by high transparency, excellent physical and mechanical properties, aging resistance, and good thermal stability. However, the strong C-F bond of PVDF itself makes i...
