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.
Unveiling the Seiden Product Types
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 films are ideal for light-sensitive environments such as darkrooms and cleanrooms where light transmission must be nearly zero. Their main features are:
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. It's important to exercise caution against solvents and spark-generating processes like RF welding.
Clear Seiden-F & Seiden Crystal: Transparency with Safety Built In

When visibility is essential, but ESD protection and fire resistance are still crucial, Clear Seiden-F and Seiden Crystal provide a balanced solution. Here are their details:
Seiden-F: Transparent film with conductive grids printed on both sides
Seiden Crystal: Clear film with higher optical clarity and a surface resistivity of 10⁹ Ω
Both materials offer excellent flame-retardant performance. They are used in cleanroom partitions, production zones, and environments that require clear visibility and static control. You can find these films in various thicknesses, ranging 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. Here are the key specifications:
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 minimizes stickiness during installation and handling. Its main features include:
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 reducing static cling. This is especially helpful during setup in controlled environments.
