S-Cube Mass Transfer Pvt. Ltd. offers engineered-grade Plastic Random Packings designed to optimize distillation, absorption, and stripping processes. These packings provide enhanced surface area and fluid distribution while maintaining low-pressure drop and high capacity.
Compared to ceramic and metal equivalents, plastic random packings exhibit lower weight and higher chemical resistance, making them ideal for corrosive service conditions.
Process Benefits of Using Plastic Random Packings
- Lower Pressure Drop: Significantly reduced ΔP across the packed bed versus conventional trays, enhancing energy efficiency.
- Increased Hydraulic Capacity: Enables higher throughput with consistent mass transfer efficiency.
- Lower Liquid Holdup: Minimizes residence time and improves process dynamics, especially critical in reactive systems.
- Versatility in Packing Geometries: Available in various types—such as Pall Rings, Raschig Rings, and Białecki Rings—suited for specific process requirements.
S-Cube Mass Transfer Pvt. Ltd. supplies Plastic Random Packings engineered for corrosive service conditions with low to moderate temperature ranges.

FAQs
Non-metallic random packings are available in various materials including ceramic (for high temperature and highly corrosive applications), plastic (PP, PVC, PTFE for chemical resistance), and other specialized polymers.
Use non-metallic random packing when dealing with highly corrosive chemicals, aggressive environments, applications requiring chemical purity, or when metal packings would corrode or contaminate the process.
Ceramic packings offer superior temperature resistance and are ideal for high-temperature corrosive applications. Plastic packings are lightweight, easier to handle, and suitable for moderate temperature applications with excellent chemical resistance.
Ceramic random packings can handle very high temperatures (up to 1000°C+), while plastic packings have temperature limitations depending on the material (typically 80-150°C for most plastics, higher for PTFE).
Non-metallic random packings are generally more cost-effective and easier to install than structured packing. They offer good performance for corrosive applications, though structured packing typically provides higher efficiency and lower pressure drop.
