PTFE Pall Ring

The PTFE Pall Ring supplied by Cixi Rylion Ptfe Company is a random packing element made from virgin Polytetrafluoroethylene (PTFE) and designed for use in chemical processing columns, scrubbers and absorption towers. Its geometry is derived from the classic Raschig ring but incorporates one or two rectangular side‑wall openings that bend inward, creating additional surface area without compromising structural integrity. The base material is solid PTFE, providing uniform chemical resistance across the entire packing surface. According to the supplier, the Pall Ring offers the same surface area and porosity as an equivalently sized Raschig ring.

Typical commercial Pall Rings have a diameter of 20 mm and a length of 30 mm, with a tolerance of ±0.3 mm, which aligns with standard dimensions used in the petrochemical industry. The packing achieves a surface area of approximately 350 cm² per ring and a void fraction around 0.55, figures that are commonly referenced in mass‑transfer design calculations. Standard packaging is a bulk bag containing 5,000 rings, wrapped in moisture‑resistant film to preserve the PTFE’s hydrophobic properties. The product conforms to the ASTM F2500 standard for PTFE packing, a widely accepted benchmark for random packings.

Primary customers include engineering firms, EPC contractors and plant operators who require reliable mass‑transfer media for corrosive streams in pharmaceuticals, petrochemicals and environmental remediation. Trade is normally conducted on an FOB‑Shanghai basis, with payment terms negotiated directly with the supplier; specific MOQ, lead‑time and Incoterms should be clarified before order placement. Prospective buyers are encouraged to request a material data sheet and a performance test report to confirm the claimed chemical resistance and mechanical strength.

Cixi Rylion Ptfe Company operates from the Kandun Block in Zhejiang province, postal code 315300, China. The supplier holds a harbour‑level trust tier, indicating basic verification, and its public profile records a response rate of 0.00 % with no average response time listed. The company’s core business is the manufacture and export of PTFE‑based components for laboratory and process‑industry applications. Buyers should note that the profile does not disclose production capacity or existing certifications.

The firm’s catalogue lists a range of PTFE products, including magnetic stir bars and random packing elements such as Pall Rings, all produced in‑house under controlled conditions. Because no third‑party audit results are published, importers are advised to request any relevant quality certificates, such as ISO 9001 or material test reports, directly from the company. The Zhejiang location provides convenient access to major Chinese ports, facilitating FOB shipments from Shanghai or Ningbo.
