产品说明:
Metocene MF650Y is an ultra-high melt flow rate resin with very narrow molecular weight distribution. It is suitable for melt blown fibers as well as compounding extrusion applications. This material is available as a free-flowing, low dust granule resin. This product contains no peroxide or peroxide decomposition by-products. The very narrow molecular weight distribution and high degree of resin consistency promote finer fibers, enhanced fiber filament thread line continuity as well as reduced fly and lint in melt blown spinning processes. Its ultra-high melt flow rate allows reduced processing temperatures and energy savings. This is a low smoke, clean running resin with good thermal and processing stability.

MF650Y是一种分子量分布非常窄的超高熔体流动速率树脂。它适用于熔喷纤维以及复合挤出应用。这种材料是一种自由流动的低粉尘颗粒树脂。本产品不含过氧化物或过氧化物分解副产物。极窄的分子量分布和高度的树脂稠度促进了纤维的细化,增强了纤维长丝线的连续性,并减少了熔喷纺丝过程中的飞丝和棉绒。其超高熔体流动速率可降低加工温度并节约能源。这是一种低烟、清洁的树脂,具有良好的热稳定性和加工稳定性。
PP聚丙烯的英文名为Polypropylene,简称PP,俗称百折胶。
聚丙烯按其结晶度可分为等规聚丙烯和无规,等规聚丙烯为高度结晶的热塑性树脂,结晶度高达95%以上,分子量在8~15万之间,本书介绍的聚丙烯主要为等规聚丙烯。而无规聚丙烯在室温下是一种非结晶的、微带粘性的白色蜡状物,分子量低(3000~10000),结构不规整缺乏内聚力,应用较少。二、聚丙烯的改性聚丙烯可通过填充,增强,共混,共聚。交联来改性。如添加碳酸钙,滑石粉,无机矿物等填料。可提高刚性,硬度,耐热性和尺寸稳定性;添加玻璃纤维,石棉纤维,云母。玻璃微珠等可提高拉伸强度。并可改善蠕变性。低温抗冲击性;添加弹性体和橡胶等可提高冲击性能,透明性等等。
