Understanding Achilles Seiden: Advanced Antistatic and Flame-Retardant PVC Films

In environments where static control, visibility, and fire safety are critical, the Achilles Seiden series offers a high-performance solution. Engineered for use in cleanrooms, darkrooms, ESD-safe areas, and industrial partitions, Seiden films combine conductive technology, flame resistance, and optical clarity to meet stringent industrial standards.

Let’s explore the different Seiden product types and their applications.

Black Seiden-F & Black Seiden Crystal BK: For Maximum Light Control

Both Black Seiden-F and Black Seiden Crystal BK are opaque, black PVC films with antistatic properties and printed conductive grids. These are ideal for light-sensitive environments such as darkrooms and cleanrooms where light transmission must be nearly zero.

• Surface Resistivity: 10⁶ Ω (on the printed side)

• Oxygen Index: 26 (JIS K 7201)

• Flame Retardancy: Complies with Japan Fire Defense Law (Art.4.3)
  

Black Seiden Crystal BK offers enhanced shading with grid printing on both sides for added conductivity and antistatic protection. Both variants require proper grounding and caution against solvents or spark-generating processes such as RF welding.

Clear Seiden-F & Seiden Crystal: Transparency with Safety Built In

When visibility is essential, but ESD protection and fire resistance are still non-negotiable, Clear Seiden-F and Seiden Crystal offer a balanced solution.

• Seiden-F: Transparent film with conductive grids printed on both sides

• Seiden Crystal: Clear film with higher optical clarity and surface resistivity of 10⁹ Ω

Both materials offer excellent flame-retardant performance and are utilized in cleanroom partitions, production zones, and environments that require clear visibility and static control. These films are available in various thicknesses, from 0.1 mm to 3.0 mm, providing flexibility for different applications.

Seiden-FW: Advanced Protection with Layered Structure

Seiden-FW combines clarity and performance by sandwiching a conductive grid between two Seiden Crystal layers. This design not only maintains high transparency but also protects the conductive layer from abrasion and chemical exposure.

• Surface Resistivity: 10⁶ Ω

• Oxygen Index: 27

• Applications: Cleanroom partitions, table mats, shelf liners, and more

This triple-layered structure offers increased durability and consistent electrostatic discharge (ESD) protection for sensitive manufacturing and electronics assembly areas.

Seiden Crystal Nashiji: Anti-Cling for Smooth Handling

Designed for ease of use, Seiden Crystal Nashiji features a matte finish that reduces stickiness during installation and handling.

• Surface Resistivity: 10⁹ Ω

• Oxygen Index: 26

• Ideal for: Dressing rooms, factory tour partitions, and semi-private installations

This semi-transparent film maintains brightness and a professional look while minimizing static cling, especially helpful during setup in controlled environments.
