pp性能和优点:
pp树脂为白色蜡状物固体,它的密度很低,在0.89
一0.92g /cm3 之间,pp是塑料材料中除4--1-烯(p4mp )之外轻的品种。聚丙烯综合性能良好,原料来源丰富,生产工艺简单,而且价格低廉。pp的力学性能与聚乙烯相比,其强度、刚度和硬度都比较高,光泽性也好。但在塑料材料中仍属于偏低的。如果需要高强度时,可选用高结晶聚丙烯或填充、增强聚丙烯。pp的冲击强度对温度的依赖性很大,其冲击强度较低,特别是低温冲击强度低。pp的冲击强度还与分子量、结晶度、结晶尺寸等因素有关。
2. pp has high crystallinity and regular structure, therefore, it
has excellent mechanical properties, its strength and hardness,
elasticity are higher than dhpe, but at room temperature and low
temperature, because of its high molecular structure, so the impact
strength is poor, when the molecular weight increases, the impact
strength also increases, but the processing performance becomes
worse, polypropylene also has excellent bending fatigue resistance,
its products can be bent 106 times at room temperature without
damage. 3. pp has good heat resistance, melting point at 164170
degrees, the product can be more than 100 degrees temperature
disinfection, in the case of no external force, 150 degrees do not
deformation, embrittlement temperature-35 degrees, in less than-35
degrees will occur embrittlement. 4. pp has excellent
high-frequency insulation performance, because it almost does not
absorb water, insulation performance is not affected by humidity,
it has high dielectric, and with the rise of temperature, it can be
used to make heating electrical insulation paper products.
homopolymeric polypropylene (pp) homopolymeric polypropylene
(homopolymeric pp) is a kind of polymer which is only polymerized
by propylene monomer. homopolypolypropylene is a semi-crystalline
polymer. because of its high crystallinity, homopolypolypropylene
has excellent mechanical properties. contains high rigidity, high
tensile strength, good heat and deformation resistance. at the same
time, because of its good fluidity, high crystallization
temperature to shorten the product molding cycle. homopolymeric
polypropylene is widely used in various processing and molding
processes such as injection molding and drawnwork. advantages of
homopolymeric polypropylene: high rigidity, high tensile strength;
chemical price resistance, acid resistance; low density, light
weight; good heat resistance; good processing formability; good
electrical insulation.
