Polyethylene Encasement:
Floats are manufactured from linear, virgin polyethylene resin containing UV inhibitors and carbon black pigment to protect against ultra violet degradation. This resin offers a balance of toughness, rigidity, environmental stress, crack resistance and low temperature impact performance unmatched by any other material. A nominal wall thickness of .15" is standard on all floats unless a specific wall thickness is requested.
The polyethylene resin used is a food grade material in compliance with the FDA Title 21. As a food grade material, the float will not contaminate the waterway.

Expanded Polystyrene:
We offer
either hollow floats or those filled with expanded polystyrene
(EPS) beads. The EPS foam has a 0.9 to 1.2 pound per cubic
foot density with water absorption not to exceed 3.0 pounds
per cubic foot as determined in accordance with the Hunt
absorption test. The EPS meets Underwriters Laboratory fire
resistance standards UL723 and UL1975. The EPS contents
will also conform to ASTM C-578 and ASTM E84.
