Hanwha Total HJ730L
PP(聚丙烯)
韩华道达尔(Hanwha Total)
产品描述
HJ730L is a highly isotactic Homo PP(HIPP) with high crystal-line properties compared to normal Homo PP. The product's crystalline properties have enhanced its strength and heat resistance.
HJ730L is highly useful for use in electrical/electronic appliances and high strength automobile parts which are exposed to lengthy periods of high temperatures.
Characteristics
Unique balance of flowability and impact resistance: processing of large scale parts
▶ High strength → thin injection molded products may be formed
▶ Ultra-high heat resistance → high service temperature
▶ High crystalinity → suitable for high speed processing
▶ Good surface hardness → excellent scratch resistance
▶ Good pigment dispersion → allows for dry coloring
Applications
▶ Home appliance such as coffee maker, kettle, etc
