Simrit Introduces Self-fusing Silicone Sinusoidal Tape; Expands Existing Product Line

Published on 2010-07-20. Author : SpecialChem

PLYMOUTH, Mich. -- Simrit, the industrial products division of Freudenberg-NOK, recently expanded its Self-fusing Silicone Tape line to include sinusoidal fiberglass reinforced tape. The company's latest offering incorporates fiberglass strands into the tape to better control the amount of stretch for consistent thickness and dielectrics, while providing improved tear and abrasion resistance.

Compliant to numerous aerospace specifications, the line's most common uses include supporting / sealing hot and cold air ducting, wire harness wrapping and wire bundling. The Self-fusing Silicone Tape meets the following: A-A 59163, Type I & II; MIL-I-22444C; DMS 2186 Type I & II; P.S. 17115; ASNA 5107; RMS 315; HS5215; P5384 Type II.

Simrit's line of Self-fusing Silicone Tape is produced out of specially formulated silicone which only bonds to itself without an adhesive, allowing for clean installation and re-entry. Once contact is made, fusion begins in seconds with 100 percent cohesion complete within 24 hours (at room temperature). The fused tape then becomes an impermeable barrier against contaminating fluid and environmental ingress while providing excellent dielectric protection (in excess of 400V per 0.001" in thickness). When servicing is required, the tape can be removed easily as there is no adhesive left on the substrate. This saves time and reduces the chance of damage to any of the underlying components.

Simrit's Self-fusing Silicone Tape line, which also includes homogeneous rectangular, triangular guideline and non-stretch formats, is ideal as an insulating material for applications requiring additional protection from environmental concerns (Ultraviolet light, ozone, fungus, salt water), chaffing, high- and low-temperatures (-55°C to 260°C), flame and fire. The entire tape line also protects against fluid splash and is compliant to Fluid Susceptibility to RTCA / DO-160F, Section 11.

The tape is produced from specially formulated silicone rubber optimizing its long operating life, superior resistance to thermal degradation, moisture, chemical attack (fuel, oil, coolant, acids, etc.) and mechanical abuse. Simrit also offers a special fluorosilicone self-fusing tape for applications that encounter prolonged contact with fuels and harsh chemicals.

Aerospace has demanding requirements for flammability and fire. Simrit has developed a Flame Retardant tape that is compliant to FAR 25.853, 25.855 and most recently a tape that can be used to achieve Fire Resistance and Fire Proof to AC20-135 / ISO 2685 (2000F for 5/15 mins resp.) "As applications and environments become more demanding, it is critical that Simrit works to address these changes with proven materials and products that fit our customers' needs," said Todd Blair, product development manager. "When we saw the need for an advanced self-fusing silicone tape that could meet even greater requirements such as improved tear and abrasion resistance, or greater fire protection, we applied our proven materials technology to develop these new products."

The Simrit Division is based at Freudenberg-NOK's headquarters in Plymouth, Mich. Freudenberg-NOK is part of the Freudenberg and NOK Group Companies, which have total annual sales of more than $7 billion. The global Freudenberg and NOK Group offers an extensive portfolio of precision-molded products for the aerospace, appliance, automotive, marine, medical, off-highway equipment, recreational vehicle and renewable energy markets.
