Using its proprietary Hostalen Advanced Cascade Process (ACP), Basell has launched a new high density polyethylene (HDPE) resin for converters of bottles used for household chemicals and daily care products.
Hostalen ACP 6031D, the new resin, can enable converters to obtain an Environmental Stress-Cracking Resistance (ESCR) of up to 10 percent higher than a typical HDPE grade with the same density, said Mike Freudenstein, Basell’s product manager for HDPE grades.
'The ACP process modifies the polymer structure to produce a material with a higher level of stress-crack resistance and stiffness,' he said.
Basell tests have also demonstrated that Hostalen ACP 6031D can help customers reduce the wall thickness of their products, according to Alexander Woerz, Basell’s application development manager.
'The high stiffness is a key to reduced weight, reduced material consumption and reduced cycle times, all of which are essential to competitiveness and value for processors', he explained.
Aside from these features, the new HDPE grade alows designers to reduce the so-called ‘panelling’ of their devices.
'Bottles made out of conventional materials run the risk of warping in the course of time because chemicals can weaken the polymer structure. Hostalen ACP 6031D based bottles stay stable due to the highly crystalline structure of the resin, which reduces the permeability of the material,' said Wörz.
The new HDPE resin is currently manufactured in Europe and is available for export.
