Solving the challenges with ATO supply chain
Over the past two years, ATO prices have surged by over 50%, with global supply chain bottlenecks causing severe shortages. Manufacturers face skyrocketing costs and uncertain lead times, creating an urgent need for a reliable alternative.
Key benefits:
Lower cost, more stability: Reduces raw material expenses by up to 50% while ensuring supply reliability.
Proven fire resistance: Passes VW-1 flame test while maintaining essential electrical and mechanical properties.
Sustainability & safety: RoHS-compliant, significantly reducing lead (Pb), arsenic (As), and mercury (Hg) content.
Seamless integration: Works as a true drop-in replacement with no changes to existing compounding processes.
“With ST-FR6, we offer a game-changing solution that helps wire and cable manufacturers stabilize costs and enhance product safety,” said Torey McCleskey, COO of CAI Performance Additives. “By eliminating reliance on ATO, we provide customers with a more sustainable and predictable supply chain”
