未经处理的聚丙烯塑料原料颗粒
聚丙烯的特性：
聚丙烯是一种无毒、无味、乳白色高结晶聚合物，密度仅为0.90 cmg，这是目前所有塑料中最轻的品种之一。对水特别稳定，在水中24小时的吸水率仅为0.01%，分子量约为8万至15万。成形性好，但厚壁产品容易因大收缩而凹陷。产品表面光泽度好，易上色
PP聚丙烯具有较低的比重（约0.90），FDA级，良好的透明度，不吸湿，价格低廉，耐热性和一般机械强度高，发泡率低，印刷适性差
PP聚丙烯结晶度高，结构规整，具有优异的力学性能，其强度、硬度和弹性均高于HDPE，但在室温和低温下，由于其高分子结构规整性，冲击强度较差，当分子量增加时，冲击强度也增加，但成型加工性能恶化
聚丙烯的突出性能是抗弯曲疲劳。例如，PP注塑成型的集成活铰链可以承受700万次的折叠和弯曲而不受损。干摩擦系数与尼龙相似，但在油润滑条件下，干摩擦系数不如尼龙
聚丙烯对紫外线非常敏感，添加氧化锌、硫代丙酸二月桂酯、炭黑或类似的乳白色填料可以提高其耐老化性
PP分为均聚物和共聚物，共聚物分为无规共聚物和嵌段共聚物。在工业上，主要是乙烯和丙烯的共聚。在无规共聚中，随着乙烯含量的增加，共聚物的无规性增加，最终成为具有弹性行为的乙丙橡胶。嵌段共聚物是PP、PE和末端共聚物的混合物
PP的抗弯曲疲劳和抗蠕变性能优于HDPE，表面硬度和刚度也高于HDPE
与聚乙烯相比，包装用聚丙烯具有密度低、硬度和硬度高、抗裂性和热稳定性好、易于加工、无毒、无味、无味、防水、耐多种无机和有机材料等优点。因此，这些物质被广泛用于食品、烟草、纺织品、医疗用品和运输的各种包装中。PP膜的透明度、光泽度、耐热性、硬度和耐针刺性均强于PE膜。包装主要采用注塑和薄膜产品

Characteristics of PP polypropylene:
PP polypropylene is a non-toxic, odorless, tasteless milky white high crystalline polymer with a density of only 0.90~0.91g/cm3, which is one of the lightest varieties of all plastics at present. It is particularly stable to water, the water absorption rate in water for 24 hours is only 0.01%, and the molecular weight is about 80,000 to 150,000. Good formability, but thick-walled products are easy to dent due to large shrinkage. Product surface gloss is good, easy to color.
PP polypropylene has low specific gravity (about 0.90), FDA grade, good transparency, no moisture absorption, low price, high heat resistance and general mechanical strength, low foaming ratio, and poor printability.
PP polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties, and its strength, hardness and elasticity are higher than HDPE, but at room temperature and low temperature, due to its high molecular structure regularity, so the impact strength is poor. , When the molecular weight increases, the impact strength also increases, but the molding processability deteriorates.
The outstanding performance of PP is the resistance to bending fatigue. For example, the integrated living hinge of PP injection molding can withstand 7 million times of folding and bending without damage. The dry friction coefficient is similar to that of nylon, but under oil lubrication, it is not as good as nylon.
Polypropylene is very sensitive to ultraviolet rays, and its aging resistance can be improved by adding zinc oxide, dilauryl thiopropionate, carbon black or similar milky white fillers.
PP is divided into homopolymer and copolymer, and the copolymer is divided into random copolymer and block copolymer. In industry, it is mainly the copolymerization of ethylene and propylene. In random copolymerization, with the increase of ethylene content, the randomness of the copolymer increases, and finally becomes an ethylene-propylene rubber with elastic behavior. Block copolymers are mixtures of PP, PE and terminal copolymers.
The flexural fatigue resistance and creep resistance of PP are better than HDPE, and the surface hardness and stiffness are also higher than HDPE.
Compared with PE, packaging PP has lower density, higher rigidity and hardness, better crack resistance and thermal stability, easy processing, and is non-toxic, tasteless, odorless, water-resistant, and resistant to many inorganic and organic materials. Substances, therefore, are widely used in various packaging for food, tobacco, textiles, medical supplies, and transportation. The transparency, gloss, heat resistance, rigidity and needle-punching resistance of PP film are stronger than PE film. The packaging mainly adopts injection molding and film products.
