UL has verified Furukawa’s flame propagation prevention performance and low smoking property performance claims of PROTECO®SHEET and PROTECO®TAPE when wound onto building wires

TOKYO, February 21, 2019 – UL, a global safety science organization headquartered in Northbrook, Illinois, has issued the first UL Verified Mark in the field of wire and cable in Japan for PROTECO®SHEET and PROTECO®TAPE, manufactured by Furukawa Techno Material Co., Ltd.

For this investigation, UL used ANSI/UL 1685, Standard for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables referenced in Article 725.179 of the National Electric Code (NEC). To verify Furukawa’s marketing claims, flame spread prevention sheet and tape wound onto building wires were tested in accordance with the methods described in ANSI/UL 1685.

The frequent occurrence of fire and disasters have led to the recent review and strengthening of testing measures. ANSI/UL 1685 test protocol assesses performance characteristics such as cable char height, total smoke released, and peak smoke release rate. Wires wound with Furukawa Techno Material’s PROTECO®SHEET and PROTECO®TAPE demonstrated the performance characteristics reported in Verification Claims displayed below.

UL’s Verified Mark demonstrates that UL has Verified a specific marketing claim through independent, repeatable, science-based assessments. UL’s Verification also provides objective credibility to the accuracy of the marketing claims that manufacturers use to differentiate their products from the competition, and enables easier purchasing decision making.

“Furukawa Techno Material’s PROTECO®SHEET and PROTECO®TAPE are thin and lightweight flame retardant rubber, but can be easily wound onto the cable or cable rack to prevent fire spreading on the cable line and have been adopted for many years at major facilities throughout the country. With the UL Verified Mark on our product, it enables us to give our customers peace of mind that the products have a science-based, objective credential and it makes customers decision-making easier,” said Mr. Masanori Owari, Director, Fire Prevention Division of Furukawa Techno Material Co., Ltd.

Product Overview

  • Type: Flame-spread prevention sheet and tape designed for building wires

UL Verification Marks


ANSI/UL 1685 measures cable char height for each specimen from the bottom of the cable tray to the highest char point of the cable covering after flame exposure. During UL’s verification, building wires wound with Furukawa Techno Material’s PROTECTO®SHEET and PROTECTO®TAPE demonstrated 2’10” (86cm) char height, 21.2 m2 total smoke released, 0.03 m2/s peak smoke release rate, and 3’2” (97cm) char height, 12.0 m2 total smoke released, 0.04 m2/s peak smoke release rate respectively.
