Resin Filtration for Polymer Production

In polymer resin manufacturing, resin filtration is essential for maintaining product quality, improving efficiency, and ensuring smooth production processes. Over time, resin filters become clogged with contaminants, additives, and debris from the polymer stream, which can lead to:

  • Increased pressure in the filtration system
  • Reduced production efficiency
  • Compromised product quality and potential defects for end-use customers

Routine cleaning and testing of filter resin components restore their functionality, extend their lifespan, and reduce the need for costly replacements.

Carolina PEC partners with polymer resin manufacturers producing a wide variety of materials, including:

  • Polyethylene Terephthalate (PET)
  • Polyamide 6,6
  • Polyethylene (PE)
  • Polycarbonate (PC)
  • Polypropylene (PP)
  • Polylactic Acid (PLA)
  • Polyetherimide

These manufacturers rely on specialized resin filters, such as leaf discs and candle filtration elements, constructed with materials like woven wire mesh, sintered fiber, and porous metal. Carolina PEC collaborates with industry leaders such as John Crane Seebach, Maag, Pall, Mott, Parker, and PTI to ensure reliable, high-quality resin filtration solutions.

Customized Cleaning Processes for Resin Filters

At Carolina PEC, we design customized cleaning profiles tailored to each customer's specific materials and additives. Our cleaning processes are carefully engineered to remove contaminants at every level:

  • Surface-level contaminants: Easily removed using traditional cleaning methods.
  • Deeply embedded contaminants: Organic and inorganic particulates lodged in filter pathways are targeted with advanced chemical, physical, and thermal cleaning methods.
  • Molecularly bound contaminants: Oxidation, scale, and residue that weaken filter media are thoroughly eliminated to restore like-new performance.

Ensuring Quality with Cleanliness and Integrity Testing

Qualifying cleanliness and integrity is a critical step in ensuring that cleaned resin filters perform effectively when returned to production. Carolina PEC offers a wide range of cleanliness and integrity tests to evaluate the condition of filters after cleaning. These tests guarantee:

  • Reliable Performance: Filters meet operational standards for extended use.
  • Consistent Quality: Clean filters ensure defect-free production.
  • Reduced Downtime: Optimized filters improve overall system efficiency.

"Throughout my career at Carolina Filters, our unwavering commitment to new and cutting edge technology has established us as the world's leader in metallic filter cleaning and testing."
