Nova introduces PE resins with non-fluorinated polymer processing aid

NOVA Chemicals Corporation announced the launch of polyethylene (PE) resins that incorporate next-generation non-fluorinated polymer processing aid (NF-PPA). The SURPASS®, SCLAIR®, and NOVAPOL® PE resins with new NF- PPA deliver comparable performance to legacy fluoropolymer PPA technology, helping manufacturers meet global regulatory compliance standards with minimal disruptions in production.

NOVA Chemicals was one of the first global PE producers to introduce PE grades with fluoropolymer-free PPA in 2022. Working closely with film manufacturers over the last three years, ongoing research led to the new NF-PPA formulation which provides enhanced process stability for consistent performance, including frost line control, reduced die-lip build-up, and predictable slip and coefficient of friction properties. It also delivers melt fracture clearing and film optics comparable to fluoropolymer-based PPA technologies. This next-generation product helps converters and brand owners adapt to evolving legislation that eliminates the use of fluoropolymers, such as the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation in the E.U.

PPAs are used to mitigate melt fracture and to prevent material buildup on die-lips during extrusion processes. The next-generation PPA is compatible with existing resin formulations, enabling the production of high-quality film structures that are free from fluoropolymers. NOVA Chemicals has obtained broad regulatory approvals for the NF-PPA resin technology in North America, Latin America, the EU, and China, with additional global approvals underway as legislation evolves.

Nine grades of PE, including FP120-D, FP120-C, SPs116-C, SPs116-D, VPsK914-C, VPsK914-D, and PF-Y821-BP, are currently available with next-generation NF-PPA for use across various blown film applications including food packaging, e-commerce, and heavy-duty sacks.
