BLOCK® Archery Targets have always touted a combination of easy arrow removal and long target life. It was these attributes that first put BLOCK® on the target map.

The quest for a better BLOCK®

In an ongoing effort to improve target performance, streamline manufacturing and reduce or eliminate unsightly product blemishes caused by internal banding, BLOCK® engineers discovered a revolutionary process they call PolyFusion™.

The two substrates used to make a four-sided BLOCK® are polyurethane and polyethylene. Polyurethane is what is on the outside of the target. It is formed by combining two chemicals that, when mixed, expand dramatically. Polyethylene is a petroleum based product that comes in the form of small beads that are melted and, with the introduction of a blowing agent, are transformed into the target’s inner layers of Friction Foam™.

Fusing polyethylene layers and polyurethane shell eliminates need for banding, wood

Managing these internal layers in the manufacturing process has always been a challenge and has necessitated the use of banding and planks of wood to assure compression. Compounding this issue is the fact that polyethylene and polyurethane do not mix well. This is where PolyFusion™ Design comes into play. A proprietary process that molecularly fuses these two very independent substrates, PolyFusion™ eliminates the need for both the wood and banding for compression. This, in turn, eliminates the product blemishing that was being caused by the bands.

No wood means a lighter weight target

Eliminating the wood and banding also means eliminating weight from the target. This is important both for the smaller targets that bowhunters like to carry with them and the larger targets that tend to be moved around in the backyard.
