The Industrial & Automotive Market Segment comprises
Within filtration systems, Dexmet's expanding technology can produce pore sizes to achieve particle filtration, specific flow rates and pressure drops to specifications. Primarily used as a pre-filter or a filter support material in pleated filters, flow rates typically are minimally affected compared to woven mesh when using Dexmet's proprietary DDB PolyGrid®. Dexmet specializes in expanding products from
Primary automotive markets include oil-less bushings,
Dexmet's expanded foil materials offer both EMI and RFI frequency shielding protection as well. Common applications are flat ribbon cable used in computer electronics and telecom applications,
For MicroGrid® Expanded Metal Foils and PolyGrid® Expanded Polymers
Dexmet precision expanded metals & expanded plastics are used in a host of primary, secondary and aftermarket automotive products. Typical applications include low-cost bearings, airbags, air filters, and oil filters. Also, expanded metals and plastics are ideal for inlet air screens, speaker grills & covers, protective mesh and decorative applications. Automotive engineers continue to adapt Dexmet MicroGrid® expanded metals and Polygrid® expanded polymers in innovative ways.
Separation and purification are key criteria for industries that process water, food & beverages, chemicals, and pharmaceuticals. Dexmet custom manufactures all MicroGrid® and PFOA-free PolyGrid® materials in a multitude of open area configurations with controlled pore sizes to provide a more consistent flow rate for your filter application.
Dexmet Corporation introduces PFOA-Free PolyGrid® Expanded Fluoropolymers. PFOA (Perfluorooctanoic Acid), widely used as a polymerization surfactant in making fluoropolymers including PTFE, PFA and FEP, has fallen under scrutiny by the EPA and FDA for its potential toxicity and widespread presence in the environment and human population.
Filter designers now have a solution to remove this harmful additive from their current or new filter designs that utilize PTFE, PFA, and FEP with a PFOA-free expanded material from Dexmet. PFOA-Free expanded PolyGrid® is also excellent for applications in the medical, filtration and separation, food processing and food packaging industry.
The Dexmet MicroGrid® EM series of expanded metal foils (EMFs) are versatile, effective materials for shielding against electromagnetic interference (EMI). They are electrically continuous and, unlike knit or woven meshes, exhibit consistent and predictable conductivity. Thin, strong, flexible and lightweight, open area products, EMFs will not fray or unravel, and conform readily to complex surfaces, making them well-suited to composite manufacturing processes.
Standard configurations include copper, aluminum, nickel and Monel meshes at .002 and .003″ thick (50 and 75µm). Dexmet can readily produce custom types using other metals and foil thicknesses, including Cu and Al types down to .001″ (25µm). The open area of the mesh can be precision-tailored to meet user requirements for weight, resistivity, formability and shielding effectiveness.
Dexmet supplies expanded metal foils and polymers for over 100 different industrial applications. From medical equipment to decorative enclosures, expanded materials can be manipulated for almost any application. The versatility of our open-area products makes it easy to dial in specific characteristics when designing a new product.
