Guangrou Dust-Free Drag Chain Sheath FAQ

1. What material is the Guangrou dust-free drag chain sheath made of?

The Guangrou dust-free drag chain sheath is primarily made of PTFE (polytetrafluoroethylene, also known as Teflon) and e-PTFE (expanded PTFE) materials. These materials offer a low coefficient of friction, good wear resistance, non-stick surface properties, excellent chemical stability, and resistance to both high and low temperatures, making them suitable for cleanroom environments. Depending on the product series, the sheath may also be a composite structure of PTFE and TPU. The sheath material can be customized based on environmental requirements such as temperature range, cleanliness class, and chemical exposure.

2. What customization options are available for the Guangrou dust-free drag chain sheath?

Guangrou dust-free drag chain sheaths support multiple customization options, including:

• Sheath color: Standard is PTFE natural (white). Black sheaths are available upon request for customization.
• Inner hole width: Customizable dimensions such as 20.5mm, 28mm, 41mm, and others.
• Number of holes: Available from a single hole to multiple holes, customizable as needed.
• Sheath thickness: Can be adjusted based on load and application conditions.
• Total sheath width: Determined by the number of holes and hole diameter.
• Material formulation: Can be adjusted to meet requirements such as flame retardancy, anti-static properties, or temperature resistance.
• Number of layers: Multi-layer configurations are available.

After the customer provides cable diameter, quantity, installation space, and other parameters, Guangrou can develop a customized sheath solution accordingly.

3. Can the flame retardancy and anti-static performance of the Guangrou sheath be customized?

Yes. The Guangrou dust-free drag chain sheath can be configured with different flame retardancy levels and anti-static performance based on project requirements:

• Flame retardancy: Standard configuration can achieve UL94 V-0 rating. Other flame retardancy standards can also be customized upon request.
• Anti-static (ESD): Customizable with self-antistatic solutions offering surface resistance of 10⁶–10⁹ Ω, suitable for electrostatic-sensitive environments.

When customizing, customers should specify their flame retardancy and anti-static requirements in advance so that the sheath material formulation and structural design can be adapted accordingly.

4. Can the color of the Guangrou dust-free drag chain sheath be selected? What is the difference between white and black?

Guangrou dust-free drag chain sheaths are available in both white and black:

• White sheath: PTFE natural color, standard configuration, and the most commonly used option.
• Black sheath: Available upon request for customization, suitable for equipment with specific color requirements or customer standardization needs.

There is no essential difference in material performance between the two colors. Both maintain the low friction, low particle generation, and wear resistance properties of PTFE. The choice between white and black typically depends on the equipment's overall appearance requirements or the customer's internal specifications.

5. Can the length and installation method of the Guangrou dust-free drag chain sheath be customized?

Yes. The length of the Guangrou dust-free drag chain sheath can be customized based on the equipment's travel distance and installation space. In addition to length customization, the installation method also supports flexible adjustment:

• Installation orientation: Supports standard mounting, inverted mounting, side mounting, and other configurations.
• Fixed end and moving end position: Can be reversed based on equipment structure requirements.
• Backbone (keel) configuration: For long-travel applications, a support backbone can be integrated into the bottom layer of the sheath. Backbone specifications (R40, R70, R125, etc.) can be selected based on travel requirements.
• Number of sheath layers: Multi-layer configurations are available to accommodate different cable quantities and space requirements.

All non-standard installation solutions should be evaluated by technical personnel based on the actual equipment operating conditions.
