Custom Gradient Tumbler 500ml Vacuum Insulated Flask
Premium Material Composition & Safety Certification
Our commitment as a responsible tumbler manufacturer begins with material selection. This 500ml smart tumbler features medical-grade 304 stainless steel (18/8 composition) that exceeds FDA, LFGB, and SGS standards for food contact safety. Unlike cheaper tumbler wholesale alternatives that may use questionable 201 stainless steel, our alloy contains 18% chromium and 8% nickel, creating an inert surface that won’t react with acidic beverages like coffee, citrus juices, or alcohol – making it ideal as a tumbler of whiskey.
The double-wall vacuum insulation incorporates a copper-plated inner chamber that enhances thermal performance by reflecting radiant heat. Laboratory tests demonstrate 12-hour heat retention (starting at 85 °C) and 24-hour cold retention (starting at 4 °C), outperforming typical 40 oz tumbler products by 35%. The vacuum pressure is maintained at 10⁻³ torr, a space-grade standard that prevents thermal transfer through conduction or convection. This design applies the same thermodynamic principles seen in high-performance vacuum flasks that use a vacuum gap and reflective coatings to minimize heat transfer
We’ve paid particular attention to the mouth-contact components. The drinking rim uses surgical-grade 316 stainless steel, while the silicone gasket is FDA-approved and free from BPA, BPS, phthalates, and lead. These safety measures make our custom tumbler suitable for children’s use, though we recommend supervision due to the digital components. The materials withstand temperatures from -20°C to 120°C without degradation, verified through 1,000 accelerated aging cycles.
For commercial users and custom tumbler wholesale buyers, we provide complete material certification documents, including:
-
FDA 21 CFR compliance reports
-
EU REACH heavy metal test results
-
California Proposition 65 compliance
-
SGS food safety certification
The exterior coating uses an automotive-grade paint process with UV protection to prevent fading. Despite its sophisticated appearance, the tumbler is fully tumbler washing machine safe (top rack recommended), thanks to the hardened coating that resists abrasion from dishwasher jets.
