Gravi-Tech™ Density-Modified Formulations High-Performance Alternative to Lead and Other Traditional Metals PRODUCT DESCRIPTION Gravi-Tech™ polymer-metal composites offer a high-performance thermoplastic-based alternative to lead and other traditional dense metals. Using a variety of metallic fibers and particles, these compounds have densities similar to traditional metals, while offering design and processing flexibility because of the polymer matrix, which can be extruded, molded, calendered, or thermoformed into the final desired shape. Several grades of Gravi-Tech composites used for radiation- shielding applications provide protections similar to traditional lead-based materials, yet these Gravi-Tech polymer-metal composites are 37 percent lighter.

When a metal propeller blade strikes a submersed obstacle with severe impact forces, it can permanently bend or break. The innovative blade design of Piranha’s Hydrothrust propeller provides 400% more reverse thrust than standard propellers and twice as much as competing metal props. Injection molding with long fiber composites makes it easy to add feature details like our Hydrobites that would be difficult and expensive to produce in metal,” said Stahl.

Therma-Tech formulations offer similar heat transfer, dissipation, and cooling capabilities to metals, when heat is transmitted into air. This combined with the design freedom, weight reduction, and cost advantages of thermoplastics, opens up the possibility to use them for metal replacement. Switching materials from a metal to a polymer carries large and potentially costly risks in terms of both performance and production, so Avient Design was consulted to help alleviate these concerns.

The concentrates provide high glossiness and metallic effects and can be customized to offer scratch resistance, anti-dust adhesion, UV resistance, and more. Our Avient Design engineering experts can support as well with the computer aided simulation of molded-in-color metallic parts to minimize surface defects. Applications: • Automotive interior trim and exterior trim components • Appliances, electronics and electrical housings • Personal care and cosmetic packaging • Painted or plated consumer products Benefits: • Efficiently replaces paint and plating for various applications • Reduces number of processing steps and complexity • Provides high glossiness and metallic effects for high-quality paint look • Can be customized to include scratch, dust, and UV resistance

Long fiber reinforced thermoplastics provide structural performance that can go head-to- head with metals at a fraction of their weight while retaining the processing ease of injection molding. Complēt™ LGF Long glass fiber reinforced engineering resins with enhanced mechanical properties that allow for metal replacement. Complēt™ LCF Long carbon fiber reinforced materials have higher rigidity/modulus, higher strength, lighter weight, and more marketability potential than glass fiber, making it the ideal fiber reinforcement for metal replacement.

These metals are strong, durable, and familiar in applications across the consumer powersports, automotive aftermarket, aerospace, and heavy truck industries. However, metals also have known limitations that impact cost, processing, and design. Long fiber thermoplastics (LFT) combine the structural integrity of metals with the lighter weight and cost-effectiveness of thermoplastic composites.

One approach is to substitute metals with reinforced thermoplastics. PROCESSING METHODOLOGIES EXPLAINED Die Casting - Metals Die casting is a type of metal casting process that injects molten metal into a mold cavity under high pressure. However, this can depend on a number of factors such as metal type, part complexity, and maintenance.
