Barrier Properties

Depending on the efficiency of KORTRAX® processing, the following barrier improvements can be obtained:

For polar hydrocarbons

from 60 to 200 times;

For other solvents and additives

up to 50 times;

For oxygen

2 to 5 times;

For aroma

excellent improvement;

Amount of KORTRAX® BR mixture to be added

5 to 9 %.

Example

The weight loss of a one liter standard HDPE bottle can be reduced by a factor of 100 by adding 5% to 9% of KORTRAX® BR when filled with xylene, toluene or similar hydrocarbons.

Material Features

• Chemical Resistant
• Good Barrier Properties
• Moisture Barrier
• Oxygen Barrier
• Permeation Resistant
• Recyclable

HIGHLIGHTS

The technology specifically consists of the production of multiple overlapping layers of barrier material in the polyethylene matrix during the extrusion process. To achieve this structure, special attention must be given to the screw, barrel, head and mold designs. Also, specific machine temperature settings are required.; Specifically, KORTRAX® is an excellent barrier to most hydrocarbons and the barrier can be achieved in blends with selected grades of HMW HDPE in extrusion blow molding of any size container or bottle. Also, oxygen barrier improvement and water vapor barrier improvement vs. pure HDPE is obtained.; Barrier improvement can also be achieved in pipes, sheets or other extruded shapes. Low or medium density PE can be processed with KORTRAX® mixtures, but the inherent lower barrier performance of these polymers must be accounted for.; In addition, KORTRAX® BR has a UV tracker that under blacklight will demonstrate the presence and dispersion of the barrier additive within the container. This non-destructive quality check gives confidence to both the convertor and the end user as to the presence of KORTRAX® thereby eliminating any doubt.

Mechanical Properties

All mechanical properties of the HMW HDPE grade used are maintained. The rigidity might increase because of the PA platelets in the matrix.
