Material Standards & Compliance Data

Engineering properties applicable across the full AWTT floating cover product range.

Resin Type

All ball and tile products manufactured from UV-stabilized High-Density Polyethylene (HDPE). NSF/ANSI 61 food-contact grade resin available on select SKUs for potable water applications.

Wind Resistance Testing

Wind resistance ratings measured under sustained load at the open water surface. Hexprotect® AQUA achieves 130+ MPH via self-loading water ballast; Rhombo Hexoshield® 66 achieves 130 MPH (water-ballasted); Rhombo Hexoshield® 189 rated at 90+ MPH; Armor Ball® AQUA 275 rated at 75 MPH.

Thermal Insulation (R-Value)

Hexprotect® MAX R achieves R-17+ via 2.5–3" closed-cell polyurethane foam fill (ASTM C518). Hexprotect® AQUA provides R-2 thermal performance via water ballast mass and low-conductivity HDPE shell.

Chemical Compatibility

HDPE shell resists dilute acids, alkalis, alcohols, and most solvents. Not recommended for concentrated oxidizing acids or aromatic hydrocarbons without prior compatibility testing. SDS sheets available on request.

UV Stabilization

All products incorporate carbon black or UV stabilizer packages rated for 25+ year outdoor service. Accelerated weathering tested per ASTM G154. Color-consistent resin blends available for regulatory pond identification.

Quality & Origin

AWTT products are supported by a North American-rooted global manufacturing network with regional production and logistics coverage. AWTT supplies a 10-year warranty on all floating cover products. Material certifications, third-party test reports, and COAs available to qualified project specifiers.

Frequently Asked Specification Questions

Request-gated certification answers and public engineering data guidance for AWTT floating cover specification.

How do I obtain official PDF specification sheets and material certifications?
AWTT provides detailed specification sheets, SDS sheets, material certifications, and third-party test reports to engineers and procurement teams at no charge regardless of order size. Submit a request through the contact page or email sales@awtti.com specifying the product or products needed.

How are wind resistance values measured and certified?
Wind resistance ratings represent verified performance under sustained wind load conditions measured at the open water surface. Hexprotect AQUA achieves 130+ MPH via integrated water fill ports and self-loading design. Rhombo Hexoshield 66 achieves 130 MPH through water-ballasted hybrid interlocking geometry. Armor Ball AQUA 275 achieves its 75 MPH rating through a self-filling water ballast mechanism. Third-party testing documentation is available upon request for specification submittals.

Which products are suitable for potable water or food-contact applications?
Hexprotect AQUA is available in NSF/ANSI 61 certified resin for potable water and food-contact applications. Armor Ball and Rhombo products use food-grade HDPE and can be supplied with NSF-grade resin certification upon request. Specify your regulatory requirement when submitting a quote request.

Are the R-17+ values for Hexprotect MAX R independently verified?
Hexprotect MAX R achieves R-17+ using 2.5 to 3 inches of closed-cell polyurethane foam fill, tested per ASTM C518. The R-2 rating for Hexprotect AQUA is derived from the thermal mass of the water ballast combined with the low-conductivity HDPE shell geometry. Complete test documentation and third-party reports are available to qualified specifiers upon request.

What is the design life basis for the 25-year service life rating?
The 25-year service life rating is based on ASTM G154 accelerated UV weathering test results extrapolated to field conditions, combined with field performance data from installations dating back to AWTT's founding. The rating assumes continuous outdoor exposure without physical damage. AWTT backs this with a 10-year limited warranty covering material defects and UV degradation.
