PRODUCT DATA SHEET

POLY-FIBER 544

PART NO. 34544

DECEMBER 2022

READ BEFORE USING THIS PRODUCT

GENERAL

Crafco Poly-Fiber 544 is a single hot-applied fiber modified asphalt-based product used to fill cracks in asphalt concrete pavements in moderate climates. Poly-Fiber 544 is supplied in solid form which when melted and properly applied forms a highly adhesive and flexible compound that resists cracking in the winter and resists flow at summer temperatures. Poly-Fiber 544 is used in highways, streets, and airfield pavements and is applied to pavement cracks using pressure feed Melter applicators. At application temperature Poly-Fiber 544 is a highly viscous, non-self-leveling product. It is designed to be installed as a simple overband or Band-Aid configuration that can be applied as a stand-alone treatment or prior to chip seal, slurry seal and micro surface treatments. The asphalt base used in Poly-Fiber 544 is polymer modified which improves both low and high temperature properties compared to fiber type products using non-modified asphalt. Since Poly-Fiber 544 is a plant blended product, problems associated with field blending of fibers are eliminated. VOC = 0 g/l.

These instructions are provided with each pallet of product.

PACKAGING

Product is supplied in either cardboard boxes, or in meltable boxless packaging. Both package types are labeled in accordance with OSHA, GHS, and specification requirements; are sold by net weight; are interlock stacked on 48 x 40 in. (122 x 102 cm) 4-way pallets; can be stored outside; and are covered with a weather resistant pallet cover and 2 layers of UV protected stretch wrap.

o BOX packaging consists of cardboard boxes containing 30 lbs. (13.6 kg) of product with 75 boxes per pallet, weighing approximately

2250 lbs. (1020 kg). Boxes contain a quick melting release film for easy removal and are taped closed, without any staples.

o Meltable packaging consists of approximately 30 lbs. (13.6 kg) completely meltable packages that are interlocked stacked on pallets. To use, the pallet wrap is removed, and individual blocks are placed in the Melter. There are no individual cardboard boxes to open, empty, handle, or dispose of. Meltable packaging quickly melts into the product without affecting specification conformance. Meltable packaged sealant products are sold by the pallet only and individual packages are not intended for sale.
