These products constitute the critical media component of clean-air systems for applications in clean-space, commercial, industrial and residential HVAC, power generation, respiratory protection, and industrial processes. Lydall has leveraged its extensive technical expertise and applications knowledge into a suite of media products covering the vast liquid filtration landscape across the transportation and industrial fields. The LyPore Liquid Filtration Media series address a variety of application needs in fluid power including hydraulic filters, air-water and air-oil coalescing, industrial fluid processes and diesel fuel filtration. LyPore media and Solupor ultra-high molecular weight polyethylene membranes also serve critical liquid filtration/separation applications such as biopharmaceutical pre-filtration and clarification, lateral flow diagnostic and analytical testing, potable water filtration and high purity process filtration such as those found in food and beverage and medical applications. Sealing and Advanced Solutions products include nonwoven specialty engineered materials for a multitude of applications. Interface fiber-reinforced gasket materials serve the heavy-duty diesel, automobile, small engine, transmission and compressor markets. These products handle demanding sealing challenges with a diverse range of metallic, non-metallic, rubber-coated and laminate materials that comprise the extensive Sealing materials portfolio. Interface Engineered Components are ready to use soft and hard gasket parts sold directly to OEMs and aftermarket applications. An example is Select-a-Seal rubber-edged composite (REC) technology that provides robust sealing, compression, adhesion, and shear strength for driveline applications. Advanced Solutions nonwoven veils, papers and specialty composites for the building products, appliance, energy and industrial markets include Manniglas Thermal Insulation Papers, and Lytherm Insulation Media for high temperature technology applications. Lydalls Cryotherm Super-Insulating Media, CRS-Wrap Super-Insulating Media and Cryo-Lite Cryogenic Insulation products are industry standards for state-of-the-art cryogenic insulation designs used by manufacturers of cryogenic equipment for liquid gas storage, piping, and transportation. Additional specialty composite materials include specialty fiber calendar bowl products to service the printing and textile industries and press pad materials for industrial lamination processes. Technical Nonwovens Segment The Technical Nonwovens segment primarily produces needle punch nonwoven solutions for a multitude of industries and applications. Products are manufactured and sold globally under the leading brands of Lydall Industrial Filtration, Southern Felt, Gutsche, and Texel. Industrial Filtration products include nonwoven rolled-good felt media and filter bags used primarily in industrial air and liquid filtration applications. Nonwoven filter media is an effective solution to satisfy increasing emission control regulations in a wide range of industries, including power, cement, steel, asphalt, incineration, mining, food, and pharmaceutical. Advanced Materials products include nonwoven rolled-good media used in commercial applications and predominantly serves the geosynthetics, automotive, industrial, medical, and safety apparel markets. Automotive media is provided to Tier I/II suppliers as well as the Company's Thermal Acoustical Solutions segment. Technical Nonwovens segment products include air and liquid filtration media sold under the brand names Fiberlox high performance filtration felts, Checkstatic conductive filtration felts, Microfelt high efficiency filtration felts, Pleatlox pleatable filtration felts, Ultratech PTFE filtration felts, Powertech and Powerlox power generation filtration felts, Microcap high efficiency liquid filtration felts, Duotech membrane composite filtration felts, along with our porotex family of high temperature filtration felts including microvel and optivel products. Technical Nonwovens Advanced Materials products are sold under the brand names Thermofit thermo-formable products, Ecoduo recycled content materials, Duotex floor protection products, and Versaflex composite molding materials. Technical Nonwovens also offers extensive finishing and coating capabilities which provide custom engineered properties tailored to meet the most demanding applications. The business leverages a wide range of fiber types and extensive technical capabilities to provide products that meet our customers needs across a variety of applications providing both high performance and durability. Thermal Acoustical Solutions Segment The Thermal Acoustical Solutions segment offers a full range of innovative engineered products tailored for the transportation and industrial sectors to thermally shield sensitive components from high heat, improve exhaust gas treatment and lower harmful emissions as well as assist in the reduction of noise, vibration and harshness (NVH). Within the transportation sector, Lydalls products are found in the interior (dash insulators, cabin flooring), underbody (wheel well, aerodynamic belly pan, fuel tank, exhaust, tunnel, spare tire) and under hood (engine compartment, outer dash, powertrain, catalytic converter, turbo charger, manifolds) of cars, trucks, SUVs, heavy duty trucks and recreational vehicles. Thermal Acoustical Solutions segment products offer thermal and acoustical insulating solutions comprised of organic and inorganic fiber composites that provide weight reduction, superior noise suppression and increased durability over conventional designs, as well as products that efficiently combine multiple layers of metal and thermal - acoustical insulation media to provide an engineered shielding solution for an array of application areas. Lydalls dBCore is a lightweight acoustical composite that emphasizes absorption principles over heavy-mass type systems. Lydalls dBLyte is a high-performance acoustical barrier with sound absorption and blocking properties and can be used throughout a vehicles interior to minimize intrusive noise from an engine compartment and road. Lydalls ZeroClearance is an innovative thermal solution that utilizes an adhesive backing for attachment and is used to protect vehicle components from excessive heat. Lydalls flux product family includes several patented or IP-rich products that address applications which include: Direct Exhaust Mount heat shields, which are assembled to high temperature components like catalytic converters, turbochargers or exhaust manifolds using aluminized and stainless steel and high performance and high temperature heat insulating materials; Powertrain heat shields that absorb noise at the source and do not contribute to the engine's noise budget; and durable, thermally robust solutions for temperature sensitive plastic components such as fuel tanks that are in proximity to high temperature heat sources.
