Sufix ProMix Braid
Lower concern for typical PFAS use; fishing line not a high-risk category, but brand discloses nothing.
Sufix ProMix Braid is a braided fishing line made from polyethylene and nylon polymers, materials without inherent PFAS chemistry. Fishing line is not a typical product category treated with PFAS coatings (unlike apparel waterproofing or food packaging).

The full breakdown
What it's made of and why it matters
Sufix ProMix Braid is a blended synthetic fiber line, typically combining polyethylene and nylon in a braided weave. This construction trades the single-material simplicity of monofilament for improved strength-to-diameter ratio and reduced stretch. The braided architecture itself poses minimal leaching risk during normal use because fishing line never contacts food, skin contact is brief and incidental, and the line remains at ambient temperature in water. Material degradation from UV or saltwater can occur over months of outdoor storage, but this is a performance issue, not a chemical safety issue.
The brand's record and disclosure
Sufix, owned by Rapala VMC, publishes no publicly available material safety data sheets, chemical composition breakdowns, or PFAS/hazard testing results for ProMix Braid. The brand has no documented recalls or safety controversies tied to this product line. Industry practice for fishing line manufacturers is minimal disclosure; Sufix's silence is typical, not exceptional, in this unregulated category. No third-party certifications (bluesign, GOTS, etc.) apply to fishing line.
How it compares in its category
Braided lines as a class have displaced monofilament in many applications due to superior abrasion resistance and knot strength. ProMix Braid sits in the mainstream performance tier; alternatives include mono (lower cost, simpler chemistry), fluorocarbon (similar hazard profile), and super-braids with fused resin coatings (coating breakdown is a known durability risk, not uniquely present here). ProMix's polyethylene/nylon blend is chemically stable and widely used; no established hazard differentiates it from competing brands in the same price range.
If you buy it
Store the spool indoors, out of direct sunlight, to slow UV degradation and extend line lifespan beyond one season. Inspect the line every few months for visible fraying, cloudiness, or brittleness; replace if it becomes rough or weak (typically 12-18 months of regular use). Wash your hands after handling if you have sensitive skin, though contact dermatitis from polyethylene/nylon alone is rare. Do not heat this line intentionally; brief incidental heat (e.g., friction from casting) poses no risk.
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.”
Microplastic shedding
Braided line can shed micro-fibers during use and storage, particularly as the weave loosens with age or UV damage. Shed fibers are not ingested (line is never food-contact) but may enter waterways; environmental rather than personal-use hazard.
Coating or adhesive degradation
ProMix Braid does not advertise a fused or resin coating; simple braided construction means no adhesive layer to break down and leach. This product avoids a known durability failure mode of some premium braids.
Heavy metals in synthetic dyes
Fishing line colorants are typically organic or mineral pigments; no public record of heavy metal testing or contamination in Sufix products. Risk is theoretical and not established in this material class.
Skin irritation or contact sensitization
Polyethylene and nylon are well-tolerated materials; no reports of allergic reactions or irritation from handling Sufix ProMix Braid. Rough or degraded line may cause mechanical abrasion but not chemical sensitivity.
Mold or bacterial growth if wet-stored
Damp storage allows moisture to accumulate in the braided weave; bacteria or mold can colonize the line over weeks, degrading appearance and potentially weakening fibers. Prevention is simple (dry storage) and does not constitute a product defect.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
