* HR-S: PARAPET™ optical grade (heat resistant)
** GR00100: PARAPET™ Impact Resistant Grade (General)
Note: The property values shown are typical values and are not guaranteed.
Physical Property Adjustment by Blending
General physical properties (hardness, heat resistance, etc.) of film grades can be adjusted by adding PMMA resin.
The table below compares the physical properties of GR-F grade film alone with those of film to which the optical grade (heat resistant), PARAPET™ HR-S, is added.
Film production method: Melt extrusion
Film forming conditions: Cylinder temperature: 230-270°C, die temperature: 250-280°C
Thickness: 75µm
