Plylok Supreme® is the flagship of the Georgia Duck line of plied rubber belting. The fabrics include 110 LB/PLY, 125, 150, 200, 250, and 300 LB/PLY. If you need a product that will meet your needs and expectations regardless of the application or environment, Plylok Supreme® will exceed those expectations.

The Plylok Supreme® fabrics utilize both polyester and nylon. With the combination of polyester and nylon, the features and benefits of both textiles can be maximized.

Polyester warp yarns yield lower stretch, better tracking, elimination of down time for re-splicing and belt break-in time. Polyester warp yarns do not absorb as much water as nylon, thereby yielding a belt with higher wet adhesions than that of a corresponding all nylon belt. Wet nylon will lose more of its tensile strength than wet polyester. For these reasons, and to retain more of the original belt’s integrity, Fenner Dunlop's fiber of choice is polyester for warp yarns.

The polyester/nylon carcass offers excellent impact resistance properties. The nylon weft yarns, with its lower modulus and higher stretch characteristics, will accept more impact from sharp objects and impingement from trapped materials without fracturing. This feature makes nylon a logical choice for the crosswise or weft member in the Plylok Supreme® belt fabric.

Fenner Dunlop has gone one step further and converted our 110 pound fabric to a poly/nylon construction.

SAFETY FACTORS

Our minimum safety factor for all Plylok Supreme® fabrics is 10 to 1 per ply. Safety factors of up to 15 to 1, often used in nylon warp constructions to reduce total elongation, are not required in Fenner Dunlop polyester warp belt constructions. With polyester having a high modulus, excess elongation is not a consideration. Excessive elongation will also cause a belt to shrink in width, resulting in a permanent cupping condition.

PLYLOK SUPREME® CARCASS

The Plylok Supreme® carcass offers unsurpassed resistance to abrasion, cutting, gouging and tearing. These properties, along with low stretch, excellent load support and increased fastener holding, will offer longer service life than most other plied belts.

BELT ELONGATION

Plylok Supreme® belts will elongate from 1.6% to 2.0% of total belt length depending on whether the carcass is the 110 LB/PLY fabric, or the 125, 200, 250, or 300 LB/PLY fabrics. These percentages are at full rated tension for the belt, not minimum tensions or average tensions, and this elongation is the total for the life of the belt.

Unlike competitive belts in the market, an initial break-in period where fasteners must be installed to compensate for excessive elongation is not needed with Plylok Supreme®. Fenner Dunlop Plylok Supreme® belts can be installed and vulcanized in one trip.
