| abstract |
The polymer sheet according to the present invention is a polymer sheet mainly composed of nano-oriented crystals of a polymer, and has a degree of crystallization of (I) of 70% or more. (II) It satisfies the condition that tensile fracture strength is 100 Mpa or more, tensile modulus is 3 GPa or more, and (III) average thickness is 0.15 mm or more. According to the present invention, it is possible to provide a polymer sheet having excellent properties such as mechanical strength, heat resistance and transparency, and a polymer sheet having excellent properties such as mechanical strength, heat resistance and transparency in general-purpose plastics including polypropylene. |
