ACHILLES BLACK SEIDEN-F, maintaining excellent flame retardancy and antistatic performance owing to conductive printing of ACHILLES SEIDEN-F, is a flexible PVC film with excellent light blocking effect of 0.0% light transmission, optimum for light blocking curtain for dark room curtain in clean room.

ACHILLES BLACK SEIDEN-F (Both Sides Printed) has special electro-conductive coating on both sides of ACHILLES BLACK SEIDEN-F.

ACHILLES SEIDEN CRYSTAL BK, developed on the basis of key characteristics of ACHILLES SEIDEN CRYSTAL such as flame retardancy and antistatic performance, is a flexible PVC film with excellent light shading effect of 0.0% light transmission, optimum for light blocking curtain for dark room in clean room.
Surface resistivity of ACHILLES SEIDEN CRYSTAL BK is on the level of 10⁹Ω, which is slightly inferior to that of BLACK SEIDEN-F.
SEIDEN CRYSTAL BK can minimize pinhole generation caused by sparks and deposit on the film surface during RF welding.

Main features

• Surface resistivity (JIS C 2170): BLACK SEIDEN-F 10⁶Ω(printed surface only), SEIDEN CRYSTAL BK 10⁹Ω (both surfaces)
• Complies with requirements of Art.4.3 of Order for Enforcement or the Fire Defense Law of Japan.
• Oxygen index 26（JIS K-7201）
