1.Basic Concepts

Ramie Fiber Packing is Highest quality ramie fiber impregnated with light-colored, special PTFE and inert lubricant during square plaiting operation. It is not harsh on shafts and stems.

2.Advantages of Ramie Fiber Packing

Excellent self-lubrication and low friction coefficient:

After impregnation (especially with graphite or grease), the packing surface is extremely smooth, resulting in a low friction coefficient against the shaft or rod, effectively reducing power loss and sleeve wear.

Excellent thermal conductivity and heat dissipation:

Both the ramie fiber itself and the impregnating agent (such as graphite) possess excellent thermal conductivity, rapidly dissipating frictional heat generated in the sealing area and preventing damage to the packing or equipment due to overheating.

High hygroscopicity and expansion:

This is a notable feature of ramie packing. When exposed to media such as water and low-pressure steam, the fibers absorb moisture and expand slightly, automatically compensating for gaps caused by wear, achieving a tighter seal and effectively preventing leaks.

Sufficient mechanical strength and wear resistance:

Ramie fiber is one of the strongest natural fibers. Its braided structure gives the packing excellent toughness and tear resistance, enabling it to withstand certain pressures and mechanical movements.

Economical:

Compared to high-end synthetic packing materials such as carbon fiber, aramid, and pure PTFE, ramie fiber packing is lower in cost and offers a high cost-performance ratio.

Environmentally friendly and biodegradable:

As a natural plant fiber product, ramie packing is environmentally friendly and will naturally degrade upon disposal.

3.Main Types of Ramie Fiber Packing

Based on the above characteristics, ramie fiber packing is commonly used in the following applications:

Centrifugal pumps, agitators, and mixers: For sealing neutral media such as water, coolants, and grease.

Valves: For valve stem sealing in low-pressure water and steam systems.

Marine industry: For sealing seawater, ballast water, and other systems.

Food and beverage industry: For sealing drinking water, juice, beer, and other media (requires packing impregnated with food-grade lubricant).

Waterworks and water supply systems: For sealing water at room temperature.

Low-pressure seals in general industrial equipment: An economical choice for general-purpose applications.
