The measured molecular weight of the ultra high molecular weight polyethylene sheet which method

2014-02-21 by seoer8

Ultra high molecular weight low molecular polyethylene plate - (UHMWPE) is a basic chemical unit of-CH2-. Thus, a long molecular chain 4 × 106 molecular weight polymer having a high molecular weight to contain 285 × 103 carbon atoms. However, the ultrahigh molecular weight polyethylene (UHMWPE) a long molecular chain, it is not dissolved in the majority of the solvent. Ultrahigh molecular weight polyethylene (UHMWPE) is not soluble, such as size exclusion chromatography (SEC) can not be applied to determine its molecular weight. Furthermore, since the ultra high molecular weight polyethylene (UHMWPE) a melt viscosity measurement can not ultrahigh molecular weight polyethylene (UHMWPE) a melt flow index of the molecular weight. Now, the measurement of the ultrahigh molecular weight polyethylene (UHMWPE) has a molecular weight of the main characteristics of two different methods to obtain, i.e., dilute solution viscosity measurements and tensile stress measurement; three different tests, and the standard is widely accepted worldwide and the use of
