Nova Chemicals Corp., a leading producer of polyethylene resins, has introduced NOVAPOL TRx0338-U and NOVAPOL TRx0535-U hexene comonomer resins. The next-generation products are designed to help rotomolders achieve unprecedented productivity and part performance.

Extensive internal and customer testing has demonstrated that NOVAPOL TRx0338-U and NOVAPOL TRx0535-U resins can reduce cycle times by up to 30% and provide a processing window at least 15% broader than traditional hexene rotomolding resins. These enhancements enable a range of additional benefits:

• Reduced cycle time enables manufacturers to produce more parts in less time at lower oven temperatures
• The broader processing window allows manufacturers to run different part sizes and thicknesses on the same arm under identical conditions without sacrificing part quality
• Processability characteristics support consolidation of traditional 3.5 and 5.0 melt index or 5.0 and 7.0 melt index grades to a single resin

“Converters are always looking to enhance their efficiency,” said Eugene Tabone, rotational molding market manager, NOVA Chemicals. “Our new NOVAPOL TRx0338 and TRx0535 grades will help rotomolders leverage the fast sintering properties of these new resins to improve their molding operations.”

With a melt index of 3.5 and a density of 0.938, NOVAPOL TRx0338 resin is ideal for small tanks, intermediate bulk containers (IBCs), roll-out waste carts, and material-handling containers for laundry and dry bulk goods. The 5.0 melt index, 0.935 density NOVAPOL TRx 0535 resin is well-suited for toys, recreational vehicle components, kayaks and stand up paddleboards, and custom parts.
