This paper took homopolymer polypropylene as the research object, and researched the formulation of better transparency polypropylene material. A variety of raw materials were mixed with direct addition method, melting extruded in a single screw extruder to granulate for sample preparation. Test criteria were based on sample preparation and testing. When α-nucleating agent was added with a mass fraction of 0.3% to homo polypropylene, the melt temperature of polypropylene sample was the highest, the degree of crystallinity was the maximum, the crystallization half time was the shortest, the light transmittance and tensile strength were the maximum, and the impact strength was the minimum. Addition of 0.3% mass fraction of α-nucleating agent as the compounding additive to homo-polypropylene could lead to preparation of polypropylene material with resistance to temperature below 150 ℃ and better transparency.
