What Arctic Zone Titan Thermal Copper Tumbler is made of, ingredients and materials
The Arctic Zone Titan uses a stainless steel outer shell paired with a copper-lined vacuum insulation layer. Stainless steel is a passive, corrosion-resistant alloy that does not leach into beverages under normal use. Copper linings in vacuum tumblers are inert when sealed behind the steel wall and do not contact liquid directly, eliminating the risk of copper leaching into drinks.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Vacuum seal degradation over time
Repeated thermal stress or mechanical damage can compromise the seal between stainless steel and copper layers, potentially allowing air ingress and loss of insulation properties. This does not pose direct chemical hazard but may encourage mold or bacterial growth if liquid sits stagnant in a failed seal.
Copper leaching from compromised seals
If the vacuum layer is physically breached through impact or manufacturing defect, copper could theoretically contact liquid. Prolonged copper ingestion is a lower concern for occasional use but is theoretically possible in a damaged product.
Bacterial or mold growth in seals
Vacuum-insulated tumblers with double walls create a difficult-to-clean cavity if moisture enters through a compromised seal or is trapped during assembly. Regular drying and inspection minimize this risk, but cannot eliminate it entirely.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Arctic Zone has no known recalls or reports of lead, cadmium, or other heavy metals in the seals or adhesives of this model. Stainless steel and copper themselves are not hazardous in food contact applications.
Source, FDA ↗Off-gassing or odor from new materials
Stainless steel and copper-lined vacuum insulation do not typically off-gas volatile organic compounds. Some users report initial metallic taste with new tumblers, which typically disappears after rinsing and use.
How is this PFAS grade calculated?
The brand's record and disclosure
Arctic Zone has not published detailed material safety disclosures or third-party certifications (e.g., FDA food-contact confirmation) on their website. The brand maintains no known public safety controversies or recalls involving this tumbler model. Without proactive transparency, buyers must rely on material class safety rather than brand assurances.
How it compares in its category
Among insulated tumblers, stainless steel construction is not a material linked to PFAS. Copper-lined vacuum designs are standard in premium thermal drinkware and carry minimal chemical risk. This product avoids the Teflon-type coating hazards sometimes found in cheaper thermal bottles and sidesteps plastic or ceramic-lined alternatives that may introduce other contaminants.
If you buy it
Hand wash the tumbler rather than dishwasher to prevent prolonged water exposure at the seams. Do not expose to extreme temperature shocks (e.g., boiling water followed by ice water) which can degrade the vacuum seal over time. Replace the tumbler if the exterior shows dents or deformation that compromise the seal. Store dry when not in use to prevent any mineral buildup inside.
