Float Specifications
All Cellofoam Floats are made to the exacting standards listed on this document. All
units are made from virgin Linear Low Density Polyethylene resin. This resin contains
UV inhibitors and Carbon black to protect from deterioration caused by U.V. light. The
resin offers a balance of toughness, rigidity environmental stress crack resistance and low
temperature impact performance. Cellofoam floats meet the Corps of Engineers
Regulation #36 CFR part 327. (See page 3).

All floats are rotationally molded for a seamless one piece construction. The encasement
is resistant to damage by animals and will not sink nor contaminate the waters if
punctured. Content of the encasement is Expanded Polystyrene foam (see sheet 2 for
specifications) with a nominal density of 1 Lb/Cu.Ft. The nominal wall thickness of the
encasement is 0.150" with a minimum wall thickness of 0.125". Custom thicknesses can
be manufactured to specific requirements. The resin used in the encasement exhibits
resilience against ice, bumping by watercraft and degradation caused by petroleum
products. The encasement is recyclable.
