New Borecene Compact™ powder grades offer unique opportunities for intricately shaped rotomoulded applications

Borealis has launched two new Borecene Compact™ PE grades to meet rotomoulders’ needs for polyethylene (PE) resins that provide enhanced flow properties, as well as improved economics and handling. The new grades, which use Borealis unique patented technology eliminating pellet grinding, offer significant advantages for technical products used in high performance applications such as parts for the automotive industry with intricate shapes. Borecene Compact’s enhanced flow characteristics deliver excellent wall thickness distribution and surface appearance.

Black Borecene Compact RM 8346-9004 represents a step advance in Borecene technology, particularly in respect of flow in complex moulds with narrow spaces and threads, and replaces Borecene Compact grades RM8346 and RM8346RC. The main application for this new grade will be 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. This will replace RM8343RC and is an ideal fit for natural diesel fuel tanks, as well as other natural colour products or products that are to be dry-colour pigmented such as toys, boats and marine applications. RM8346-1000 will carry the same excellent diesel fuel barrier performance as the black version above.

Introduced in 2002, the Borecene Compact family was the first-ever black polyethylene in a form that completely eliminates pellet grinding. This provides for a dust-free working environment, higher product quality and improved consistency, including better carbon black homogenisation. And, as its name suggests, Borecene Compact has increased bulk density and therefore takes up less volume, making its transport and storage more efficient. It enables rotomoulders to improve productivity through shorter cycle times and it gives improved dry-flow for easier mould filling, narrower particle size distribution to achieve a better surface finish with fewer wall bubbles, and enhanced mechanical properties in the finished product.
