Polymer Raschig Ring (Plastic)
Polymer Raschig Rings are made from materials that are resistant to heat and corrosion. Common materials include:
- Polyethylene (PE)
- Polypropylene (PP)
- Improved Polypropylene (RPP)
- Polyvinyl Chloride (PVC)
- Chlorinated Polyvinyl Chloride (C-PVC)
- PVDF

Reference products from established manufacturers. YUXINGCORP coordinates sourcing; it is not the manufacturer.
Characteristics
The characteristics of these products include:
- High void space
- Low pressure drop
- Low mass transfer per height unit
- Uniform contact of gas-liquid phases
- Low specific mass
- High mass transfer efficiency
These rings are suitable for temperatures ranging from 30 to 150 degrees Celsius. They are widely used in industries such as chemical, petrochemical, alkaline and chloride industries, coal gas, and environmental protection. By using specialized engineering polymer materials, the working temperature range of the packing can be increased.
Cylindrical packing represents the first generation of random packing and remains in use due to its fast production rate and low cost, making it attractive for various industrial applications.
Applications
Polymer Raschig Rings are used in various applications, including:
- Separation
- Adsorption
- Desorption equipment
- Normal pressure drop equipment
- Decarbonization of synthetic ammonia
- Desulfurization
- Separation of ethylbenzene, isooctane, or methane

How We Work - Our Commitments
Each commitment carries a condition and a remedy. A promise without conditions is marketing.
- Sourcing & Supplier Matching
Commitment:
A written sourcing report within 48 hours of a complete requirement brief.
Conditions:
Requires machine type or output target, destination country, and timeline. Custom or multi-line projects may take longer – we tell you upfront.
Remedy:
If we cannot meet it, you receive an interim response with a firm date –
not silence.
- Pre-Shipment Inspection
Commitment:
Third-party pre-shipment inspection – SGS or BV – before balance payment is released.
Conditions:
Included as standard on production-line projects. Available on request for single machines. Scope agreed in writing before booking.
Remedy:
If inspection fails against the agreed specification, shipment does not release until corrected or you approve a deviation in writing.
- Export Documentation
Commitment:
Complete export document pack – commercial invoice, packing list, certificate of origin, and destination-specific conformity documents.
Conditions:
Destination conformity regimes (CE, EAC, SABER/SASO, PVOC, SONCAP) vary and change. We confirm the applicable route per project before contract.
Remedy:
If a document we are responsible for causes a customs hold, we resolve it and carry the correction cost.
- Warranty & After-Sales
Commitment:
12-month equipment warranty with a named responsible contact and a written spare-parts dispatch commitment.
Conditions:
Covers manufacturing defects under normal operation and specified maintenance. Wear parts and consumables excluded.
Remedy:
Dispatch window and remedy – details to be confirmed. Contact us for project-specific warranty terms.
