Well, we do not want to match them, we go beyond them. Our block with the same dimensions weighs 105 pounds, over 25% higher density! They claim that no other manufacturer can match their capabilities. For example, their 9” x 12” x 24” D- Block weighs about 78 pounds. They sell their product by volume, not weight. While their product has not changed in decades, we continue our efforts to improve our product. They have been hyperactive in their attempts to disparage our vulcanized product because of the low quality and poor physical properties their rubber possesses. But the test is only with their product! There is no direct performance comparison with a competitor, and we know why. Being first doesn’t always mean the best (Motorola made the first cell phone)! They claim their rubber has been tested by Picatinny Arsenal, among a few others. One of our competitors claims to be the first to manufacture ballistic control rubber. What they are really saying it has been made to be replaced. Our competition has been making “grind and glue” rubber and claiming that it has been made originally and exclusively to be shot at in ranges. Ours has been tested by the Akron Rubber Development Laboratory. Please ask any of other ballistic control manufacturers you are considering to provide their material testing data on the properties we listed above. Our rubber will stretch to about 200% of its original size. When a bullet round strikes rubber, the rubber should stretch and allow the bullet to pass through and then rebound to its original position allowing it to take a high number of strikes while preventing escapes. Elongation is measured by taking a sample piece of the rubber and stretching it until it breaks. A test called “ultimate elongation” is a crucial property in ballistic control rubber performance.

Tests like tensile strength, durometer, modulus, and density are routine rubber tests. Most properties are measured by impacting stress to the rubber. The physical properties of rubber polymers have been measured scientifically for years. Then its energy and original shape are lost so it safely comes to rest between the rubber and the hard surface (usually steel). The rubber allows the bullets to pass through it and then strike a hard surface. Rubber can stop some rounds (depending on the thickness) but usually not. Ballistic rubber is used to prevent escapes and ricochets in gun training ranges.
