NOVA launches first “single-site” resins

NOVA Chemicals has introduced four new commercial grades of polyethylene made using the company’s Advanced Sclairtech single-site catalyst technology. The new line of film-grade materials, given the trade name SURPASS, are the first materials produced by a combination of NOVA’s Advanced Sclairtech and proprietary single-site catalyst technology. NOVA says the new resins deliver a unique combination of properties not found in conventional metallocene resins. Processing advantages being claimed for SURPASS resins include higher outputs, lower extrusion pressures and decreased power consumption.
“Processors no longer have to sacrifice or choose between desired properties, like toughness, tear strength, clarity and processability,” said Dale Spiess, senior vice president and president, olefins/polyolefins.
The new resins are being manufactured at NOVA’s Joffre plant in Alberta. The plant has an annual capacity of 850 million lb.
