Sonoco plastic filtration cores, cages, endcaps and purpose-built components meet the highest industry standards for quality, performance and reliability. Sonoco is a leading global supplier of plastic filtration parts designed for optimal efficiency and manufactured using environmentally conscious practices. Sonoco’s high-quality, precision-engineered plastic filter components are designed to meet the strict regulations of the liquid, air and medical filtration markets.
Types of Plastic Filtration Cores
Our plastic filtration cores feature superior structural strength, chemical resistance, and thermal stability to meet the most demanding requirements. The basic design incorporates the use of longitudinal and radial ribs engineered to furnish high collapse strength. A stipple finish on the filter core aids in retention of the initial placement of fibers.
Heavy Wall & Wildcatter Filter Cores
Sonoco’s heavy wall plastic filtration cores are engineered for filtration applications that require added strength and durability. Available in a variety of materials—including polypropylene, 40% glass-filled polypropylene, PBT, acetal and 33% glass-filled nylon—these filter cores offer enhanced performance under higher pressure and temperature conditions. They provide increased collapse strength and thermal resistance compared to standard wall filter cores, with a smooth finish and 13% open area for flow-through.
Built for performance in various environments, Sonoco’s Wildcatter filter cores provide high collapse strength, thermal stability, and strong chemical resistance. These plastic filtration cores are well-suited for use in string-wound and melt-blown filters and feature a stippled finish that helps retain initial windings during filter assembly.
Wildcatter cores are available in multiple materials, including polypropylene, 40% glass-filled polypropylene, acetal, and 33% glass-filled nylon. Additional material options can be discussed based on application requirements. Designed for high flow-through, these filter cores maintain structural integrity under pressure and elevated temperatures, making them a reliable choice for rugged filtration needs.
Specialty, Coalescing, Pool & Spa Filter Cores
Sonoco Crellin produces a wide range of specialty plastic filtration cores designed to meet the unique demands of various filtration systems. These filter cores are built with longitudinal and radial ribs, manufactured from a selection of thermoplastic resins, and held to tight dimensional tolerances. Custom cut sizes are available to meet specific application needs. These filter cores offer the flexibility to optimize performance while managing cost.
Coalescing filter cores are built for large-diameter applications and provide high collapse strength and temperature resistance. Designed with a smooth finish and greater open area for flow, they are available in ABS, polypropylene, 33% glass-filled nylon and glass-filled ABS—making them a strong choice for demanding separation processes.
Pool and spa filter cores are specifically designed for use in pleated cartridge filters. With a wall thickness of 0.125 inches and 56.5% open area for flow, these cores are stackable, feature a smooth finish, and are available in polypropylene and talc-filled polypropylene for added rigidity.
Standard Filter Cores
Sonoco’s standard plastic filtration cores are available in both standard and thin-wall designs, providing reliable performance for a wide range of filtration applications. These filter cores feature longitudinal and radial ribs, are produced from various thermoplastic resins and are manufactured to tight dimensional tolerances for consistency and efficiency.
Designed to balance performance and cost, our standard filter cores offer high collapse strength, excellent flow-through, thermal stability, and chemical resistance. Our cores also come with a stippled finish that helps retain the initial windings of string-wound and melt-blown filters and feature a 1.093" inner diameter, 0.105" wall thickness and 23% open area for flow.
Available material options include polypropylene, 40% glass-filled polypropylene, ABS, acetal and 20% glass-filled nylon.
Plastic Cages and Endcaps
In addition to filter cores, Sonoco offers a full range of components for plastic filter cartridges, including cages, adapters, and endcaps. These filter components are molded from specially engineered resins that provide strong resistance to chemical attack from both acidic and alkaline substances, supporting long-term durability in demanding filtration environments.
Sonoco delivers reliable solutions for a wide range of filtration applications, with a broad selection of plastic filtration cores, components and custom options available.
