Maxima Ultragreen Maxi Spools
Lower PFAS concern for this product category, but Maxima offers no transparency on material treatment.
Maxima Ultragreen Maxi Spools are fishing line made from monofilament nylon. The brand does not disclose PFAS use or avoidance. Monofilament line itself is not inherently a PFAS vector, but some fishing lines have been treated with water-resistance or UV coatings that could contain PFAS, Maxima provides no public information to rule this…

The full breakdown
What it's made of and why it matters
Maxima Ultragreen Maxi Spools are extruded nylon monofilament, a single continuous polymer strand. Nylon fishing line does not involve ceramic or metal coatings, so lead/cadmium glazing hazards common in cookware do not apply. The material is stable at room temperature and during typical freshwater/saltwater use; nylon does not leach monomer or plasticizer into water under normal fishing conditions. The primary concern with any monofilament is microplastic fragmentation after breakage or weathering in aquatic environments, though this is an environmental rather than consumer safety issue.
The brand's record and disclosure
Maxima is a long-established fishing tackle manufacturer (founded 1970s) with no documented recalls or safety controversies in public databases. The company does not publish transparency reports on material sourcing, chemical treatments, or PFAS use in manufacturing. No third-party certifications (e.g., for dye safety or processing chemicals) are publicly available for this line. The 'Ultragreen' marketing suggests environmental positioning, but no substantiated claims about reduced chemical inputs or safer treatments are documented.
How it compares in its category
Most monofilament fishing lines (Berkley, Seaguar, SpiderWire) have similarly sparse public hazard data, reflecting the category norm of minimal disclosure. Ultragreen sits in the mid-market price tier with no known performance or safety advantages over generic monofilament. Unlike braided or fluorocarbon alternatives, monofilament carries no reported issues with heavy metal dyes or flame retardant coatings. The main trade-off is that nylon monofilament degrades faster under UV exposure than some synthetics, requiring periodic replacement.
If you buy it
Store spools in cool, dry, dark conditions to slow nylon UV degradation and maintain strength. Replace line annually or after heavy use, as brittle or discolored monofilament signals chemical breakdown. Rinsing and drying spools after saltwater use extends life and reduces salt-induced corrosion on reel components (not the line itself). Do not expose unused spools to direct sunlight or heat sources; nylon's tensile strength declines measurably above 60-70 degrees Celsius during storage.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Nylon monomer/oligomer leaching
No documented leaching of caprolactam or nylon oligomers into water or on hands during normal fishing use. Monofilament is a cross-linked polymer with low migration tendency at ambient temperatures.
Azo dyes or heavy metal colorants
Maxima does not disclose dye chemistry for the 'Ultragreen' pigmentation. Nylon accepts synthetic organic and inorganic dyes; if cadmium or lead-based colorants were used, they would remain bound in the polymer and pose minimal direct contact risk, but manufacturing waste streams are not publicly tracked.
Flame retardant additives
Fishing line is not treated with flame retardants as a product category; nylon itself is thermoplastic and does not require additional FR chemicals for safety certification.
UV degradation byproducts
Prolonged sun exposure of nylon monofilament causes polymer chain scission and release of volatile organic compounds (formaldehyde, ammonia) and microplastics during degradation. This is an environmental hazard rather than direct consumer toxicity, but extended storage in sunlight should be avoided.
Additives in manufacturing (UV stabilizers, slip agents)
Nylon extrusion typically includes proprietary additives (hindered amine light stabilizers, lubricants); Maxima does not disclose these. Standard additives are not flagged as hazardous in industrial safety data, but transparency is absent.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 65% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
