Quality & Certification: Thermal Insulation Performance Test Reports

When sourcing a vacuum insulated cup for your vehicle or outdoor use, one of the first questions you may ask is: "Can you provide test reports for thermal insulation performance?"

At flaskme — the brand of ZHEJIANG KUANGYI INDUSTRY AND TRADE CO., LTD. — we understand that verified performance data builds trust. Below we explain how our insulation performance claims are validated, what the standard test covers, and how you can request detailed reports for the 40oz handle car cup (Model: ZJKY029).

Insulation Performance of the 40oz Handle Car Cup

Our 40oz handle car cup is designed with 304 stainless steel liner material and 201 stainless steel shell material. This double-wall vacuum construction contributes to its rated insulation performance of 6–12 hours for both hot and cold beverages.

What Does the Insulation Test Report Include?

The thermal insulation performance test report for our car cups typically includes:

• Test conditions: Ambient temperature, initial liquid temperature, and fill volume.
• Temperature measurement: Internal liquid temperature recorded at specified time intervals (e.g., 1h, 3h, 6h, 12h).
• Surface temperature: Checking the outer shell for safe touch temperature.
• Sealing performance: Lid and straw sealing to prevent leaks that affect heat retention.

These reports are generated based on standardized testing procedures and are available upon request.

Requesting a Test Report Before Bulk Order

As noted in our product FAQ: "Very glad to tell you that we can supply free sample for quality testing. Usually send out by DHL, FedEx, TNT or UPS. Only shipping cost charges." This means you can request a pre-production sample to test the thermal insulation yourself. If you need an official test report, our team will gladly share the relevant documentation for your evaluation.
