A new polyethylene grade eliminates the need for pellet grinding and offers rotomolders high barrier performance for automotive applications. The improved processability of the resin in comparison to powder enables the rotomoulding of very complex, intricate shapes in a more cost-efficient way. Borealis has launched two new Borecene Compact™ PE grades to meet the PE needs of rotomolders, with enhanced flow properties that deliver excellent wall thickness distribution and surface appearance, as well as improved economics and handling.
Introduced sometime in 2002, the Borecene Compact family is recorded to be the first-ever black polyethylene that completely eliminates pellet grinding. It is estimated to provide for:
· A dust-free working environment
· Higher product quality and improved consistency
· Better carbon black homogenisation.
· Increased bulk density, making its transport and storage more efficient.
· Improved productivity through shorter cycle times
· Improved dry-flow for easier mold filling
· Enhancing mechanical properties in the finished product
· Narrower particle size distribution to achieve a better surface finish with fewer wall bubbles
Black Borecene Compact RM 8346-9004 is an advance step in Borecene technology, particularly in respect of flow in complex molds with narrow spaces and threads, and will mainly find application in diesel fuel tanks, where its barrier performance is superior to standard linear and crosslinked resins.
Borealis is also launching a new natural colour Borecene Compact grade RM8346-1000, which provides extra high UV resistance, and is an ideal fit for natural diesel fuel tanks, as well as other natural colour products or products that are to be dry-color pigmented such as toys, boats and marine applications.
