Antimony-free Flame Retardant Fills Gap Created by Chinese Export Restrictions

Michigan’s Highland Plastics has countered a Chinese ban on antimony exports by launching its antimony-free Kelvinite 2100, a halogen-free, flame-retardant polypropylene (HFFR PP) that will keep automakers supplied with a made-in-the-USA option.

Reuters reported in August that China would impose export restrictions on some antinomy products starting Sept. 15, 2024. The Chinese government cited national security concerns as a reason for curtailing exports.

With a manufacturing lead time of four weeks, Kelvinite 2100 will sustain the requirements of OEMs and Tier 1 manufacturers who had raised a red flag over a potential antimony shortage. China maintains 48% of the world’s antimony supply.

Environmental alternative

Kelvinite 2100 is also suited for consumer electronics, construction, and appliance applications because it meets UL94 V-0 and VTM-0 standards at thin gauges, including as thin as 0.010 in. (0.25 mm). It is also RoHS and REACH compliant, making it eco-friendly as well as safe.

Highland Park’s HFFR PP alternative supports most die-cutting, knife-cutting, kiss-cutting, snap-fit, and lamination operations. Kelvinite 2100’s other benefits include:

Eliminates sourcing challenges

“Kelvinite 2100 not only eliminates the sourcing challenges associated with antimony — it also provides unmatched performance that legacy FRPP materials simply cannot provide,” said Ben Simmons, CEO of Highland Plastics. “With Kelvinite 2100, manufacturers can confidently meet flame-retardancy and environmental standards without compromising on quality or reliability. And, we can deliver with a four-week lead time to meet immediate demand.”
