Tested according to GB/T 1034-2008. Test temperature (23 ± 2) ° C, time (24 ± 1) h. The sample is selected from the surface without surface treatment (thermal transfer or film coating), the specification is (40 ± 1) mm × (60 ± 1) × original wall thickness of the plate
2, PP hollow sheet tensile strength and elongation at break
Tested according to GB/T 1040-2006. The sample is a type I sample, and the sample is selected from a sheet which has not been surface-treated (thermal transfer or film) and has an original wall thickness, and the stretching speed is (20 ± 2) mm/min.
3,PP hollow sheet bending strength and flexural modulus
Tested according to GB/T 9341-200. The sample is selected from a sheet which has not been surface treated (thermal transfer or film), and the outer surface is the largest fiber deformation surface.
4, PP hollow simply supported beam impact strength
Tested according to GB/T 1043-2008. The sample is a non-notched type I sample, and the sample is selected from a surface that has not been surface-treated (thermal transfer or film) and taken to its original wall thickness to impact the inner surface of the crust.
5, PP hollow sheet Vicat softening point
Tested according to GB/T 1633-2002. The test load is g, and the isothermal heating rate is (50 ± 0.5) ° C / h. The sample was selected from a surface that was not surface treated (thermal transfer or film) to measure the outer surface of the crust.
6, PP hollow sheet Shore hardness
