I.概述
聚丙烯的英文名称：聚丙烯，缩写：PP，俗称：百分之百塑料。聚丙烯是聚α-烯烃的代表，聚α-烯烃是通过丙烯聚合制备的热塑性树脂，其单体为丙烯CH2=CH-CH3。根据引发剂和聚合工艺的不同，聚丙烯可分为三种构型：等规聚丙烯、无规聚丙烯和间规聚丙烯。等规聚丙烯易于形成结晶状态，结晶度大于95%，分子量在80000到150000之间，具有良好的耐热性和耐溶剂性；无规聚丙烯是一种非结晶、室温下的白色蜡状材料，具有轻微的粘性、低分子量、3000-10000、不规则结构、缺乏内聚力、应用较少

2。特性
无毒、无味、低密度、强度、刚度、硬度和耐热性优于低压聚乙烯，可在100℃左右使用。它具有良好的介电性能和高频绝缘性，不受湿度影响，但在低温下变脆，不耐磨，易老化。适用于制造一般机械零件、耐腐蚀零件和绝缘零件。常见的有机溶剂如酸和碱对其影响不大，可用于餐具
1。相对密度较小，仅为0.89-0.91，是一个较轻的塑料品种
2。机械性能好，除耐冲击外，其他机械性能均优于聚乙烯，成型性能好
3。耐热性高，连续使用温度可达110-120℃
4。它具有良好的化学性质，几乎不吸水，并且不与大多数化学品发生反应
5。质地纯净无毒
6。良好的电气绝缘性
7。聚丙烯制品的透明度优于高密度聚乙烯制品<它有许多优点，但也有缺点：
1。耐寒性和低温冲击强度差
2。产品在使用过程中容易因光、热和氧气而老化
3。颜色不好
4。容易燃烧
5。韧性差、静电高、染色、印花和附着力差

MFR 1500 PP polypropylene raw material for pp Meltblown

I. Overview
English name of polypropylene: Polypropylene, abbreviation: PP, commonly known as: hundred percent plastic. Polypropylene is a representative of poly-α-olefin, a thermoplastic resin prepared by polymerization of propylene, and its monomer is propylene CH2 = CH-CH3. According to different initiators and polymerization processes, polypropylene can be divided into three configurations: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. Isotactic polypropylene is easy to form a crystalline state, with a crystallinity of more than 95% and a molecular weight between 80,000 and 150,000, giving it good heat resistance and solvent resistance; random polypropylene is a non-crystalline, at room temperature, White waxy material with slight stickiness, low molecular weight, 3000-10000, irregular structure, lack of cohesion, less application.

2. Features
Non-toxic, odorless, low density, strength, stiffness, hardness and heat resistance are better than low-pressure polyethylene, can be used around 100 ℃ It has good dielectric properties and high-frequency insulation and is not affected by humidity, but it becomes brittle at low temperatures, is not wear-resistant, and is easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common organic solvents such as acids and alkalis have little effect on it, and can be used in tableware.
1. The relative density is small, only 0.89-0.91, which is one of the light-weight plastic varieties.
2. Good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, molding performance.
3. It has high heat resistance, and the continuous use temperature can reach 110-120 ℃.
4. It has good chemical properties, hardly absorbs water, and does not react with most chemicals.
5. The texture is pure and non-toxic.
6. Good electrical insulation.
7. The transparency of polypropylene products is better than that of high-density polyethylene products.

It has many advantages but also disadvantages:
1. Poor cold resistance and low-temperature impact strength.
2. The product is susceptible to aging due to light, heat and oxygen during use.
3. Poor coloring.
4. Easy to burn.
5. Poor toughness, high static electricity, poor dyeing, printing and adhesion

Application: Meltblown
