In addition, with the addition of the Shanghai Sacidae C1007-PP material, the light transmittance of the PP hollow plate is obviously increased, and when the Shanghai Sacidae C1007-PP is excessive (comparative example 4), the toughness and tensile strength are obviously reduced. In addition, the surface performance of the material is greatly influenced by the medium petrochemical Qilu K8003-PP material, and the cracks and the surface roughness are obviously reduced along with the increase of the medium petrochemical Qilu K8003-PP material (comparative examples 5-6).
