This abundant supply includes thousands of tons of PVB, found in the inner layer of the glass, potentially bound for landfills. Instead, the outer glass is recycled and the PVB is reclaimed and reprocessed for various uses, including an alternative raw material source for polymers. These injection moldable TPEs can be overmolded to polypropylene (PP) and come in a natural grade that can be easily colored.

Edgetek™ PKE Glass-Filled Formulations The Edgetek PKE Glass-Filled (GF) series consists of specialty engineered, glass-reinforced polyketone (PK) thermoplastics. Available with 10–40% short glass fiber fillers, these formulations provide superior chemical resistance, low moisture uptake, excellent dimensional stability, and high impact and wear resistance. KEY CHARACTERISTICS • Excellent chemical resistance • Low moisture uptake • Comparable dimensional stability to nylon • Reinforced with 10–40% short glass fiber • High impact and wear resistance • Cost competitive • Eco-conscious alternative to PA66 and PA6 • Non-halogen, flame retardant performance MARKETS & APPLICATIONS These glass-reinforced materials meet the challenges found in chemical, fuel contact, and high moisture environments

GlasArmor panels made with fiber-reinforced polymer (FRP) composites provide excellent ballistic stopping power for the MPS while meeting the requirement of being lightweight and portable. They are constructed from layers of 0°/90° woven E-glass fiber reinforcements combined with a proprietary resin system in a continuous pultrusion manufacturing process. The composite material is 25% the weight of comparable steel structures, and also weighs significantly less than concrete, making them easily deployable in the field.
