BLOW CONTAINER

PROBLEM TO BE SOLVED: To provide a container for a high-purity chemical, which is good in chemical resistance and generates few microparticles into the chemical.SOLUTION: An ethylenic polymer is used in which the density is 920 to 970 kg/cm; MFR is 0.005 to 1 g/10-min; in a molecular weight measurem...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a container for a high-purity chemical, which is good in chemical resistance and generates few microparticles into the chemical.SOLUTION: An ethylenic polymer is used in which the density is 920 to 970 kg/cm; MFR is 0.005 to 1 g/10-min; in a molecular weight measurement using gel permeation chromatography, there is two peaks exhibited; the ratio (Mw/Mn) of the weight-average molecular weight (Mw) and the number-average molecular weight (Mn) is in the range of 2.0 to 7.0; the proportion of components having Mn of ≥100,000 in the molecular weight fractionation is
