Effects of a mixture of stabilizers on the structure and mechanical properties of polyethylene during reprocessing
In this work, two extrusion grades of polyethylenes,
HDPE [Alcudia C-240-UV (Repsol YPF, Spain)] and
LDPE [ Lupolen 1840 H (Basell, Wilmington, DE)],
Synthesis and characterization of thermoplastic composites filled with γ�?boehmite for fire resistance
Low-density poly(ethylene) (LDPE LUPOLEN 1840 H from
BASELL) exhibits a low polarity, whereas poly(amide) 6 (DINALON PA6 from REPOL) presents
a higher polarity.
General purpose extrusion LDPEa valuable additive in various rubbers, thermosets, and
( Lupolen 1840 H , melt ow index=1·5 dg min – 1 atthermoplastics.
Linear viscoelastic model for elongational viscosity by control theory
first simulate a modern LDPE ( Lupolen 1840 H ) for
well known and classical IUPAC A, as done previously
Capillary rheometry for polymer melts revisited
The two materials investigated with regard to the
pressure dependence of viscosity are Lupolen 1840 H (LDPE in Figs. 7 and 9a) and Luran KR 2556 (PaM-
SAN in Figs. 5, 6, 8 and 9b).
Pressure dependent viscosity and dissipative heating in capillary rheometry of polymer melts
An LDPE melt ( Lupolen 1840 H , batch 776–130010)
at 150 °C was selected as experimental example.
Influence of molecular structure on rheological properties of polyethylenes
1 is available under the trade name Lupolen 1840 H from BASF, Ludwigshafen, the LDPE 2 is a stabilized
Lupolen 1810 H from BASF and the LLDPE is sold by
the DOW Chemical Company as Dowlex NG 5056 E.
Investigation of LDPE converging flows using fieldwise measurements techniques
Lupolen 1840 H .
Comparative investigations of surface instabilities ("sharkskin") of a
linear and a long-chain branched polyethylene
The LDPE used was Lupolen 1840 H from Basell, a commercial product frequently used
for film extrusion and film blowing.
A simple method of measuring radiation dose in the
megarad range using low-density polyethylene film
...an unknown dose, samples of both types
also be simplified by
molecular weight. Lupolen . 1840 D (melt flow index
between 0.1 and 0.3),for example, has a considerably higher molecular weight
than 1800 H (mfi between 1.2 and 1.7), its gel point (at about 1 hlrad for
1840 D) and linear dependence...
