Nitto P-55 vs Polyken 108FR: Aircraft Carpet Tape Compared

Aerospace Tapes · Aircraft Carpet Tape · BMS 5-133 · FAR 25.853

The Nitto P-55 is a known quantity on aircraft interior jobs — a flame retardant double-coated cloth tape for installing carpet on cabin floors and stairways. The Polyken 108FR is the same kind of tape, built to the same core specifications, and it's typically the lower-cost way to meet them. Both carry Boeing BMS 5-133 and FAR 25.853(a); the practical decision comes down to cost, documentation, and how cleanly the tape comes back up.

What the Nitto P-55 Does Well

The P-55 (white) and P-55B (black) are high-performance flame retardant double-coated cloth tapes with a cured rubber/resin adhesive. The adhesive has quick-stick properties and builds bond strength with age, and the tape lists a high adhesion to steel (105 oz/in). Nitto's data sheet documents Boeing BMS5-133G (Type II, Class 1 for P-55; Class 2 for P-55B), Boeing BAC 5034 Type IV, Airbus ABS 5648A, and FAR 25.853. It's a proven aerospace carpet tape with a real track record.

Where Polyken 108FR Pulls Ahead

1. Same core spec, typically lower cost

Both tapes meet Boeing BMS 5-133, BAC5034-4 Sec 5.1.a(1)(b), and FAR 25.853(a) — the specifications most commonly called out for aircraft carpet installation. When the job references those specs, the 108FR is a direct substitution and is typically the more cost-effective way to meet them. For high-volume interior refurbishment, that per-roll difference adds up across a fleet program.

2. Clean, repositionable removal

The 108FR is engineered for a secure hold with clean, residue-free removal — the property that matters most when carpet is bonded and later pulled up on high-value aircraft interiors during MRO and refurbishment. Nitto's own data sheet notes the P-55 is a high-adhesion product that may delaminate some surfaces. Higher initial grab isn't always the goal; clean removability often is.

3. Broad, individually listed OEM approvals

The 108FR data sheet enumerates a wide approval set — Boeing BMS 5-133 and BAC5034-4, FAA FAR 25.853(a), Airbus ABD0031 Para 7.4, Douglas DMS 1971, Lockheed LAC C-24-1257, Embraer MEP 06-048, Fokker FK05-121 & FK05-197, and Bombardier DSC 91-8-1 & DSC 91-8-2. For mixed-fleet MRO operations spanning multiple airframers, having those approvals individually cited reduces approval ambiguity at the maintenance event.

4. Free lot-specific Certificate of Conformance

Every shipment of Polyken 108FR from Skytapes includes a free Certificate of Conformance — standard, not a special request. In regulated maintenance environments where traceability is mandatory, that's the difference between tape you can use immediately and tape waiting in receiving inspection for paperwork.

Where the Nitto P-55 Still Has the Edge

To be straight about it: the P-55 lists a higher adhesion to steel (105 oz/in vs. 60 oz/in for the 108FR). If your application calls for maximum initial grab, that's a real advantage. The P-55 also carries Airbus ABS 5648A as a specifically documented Airbus carpet-tape approval, which matters if your engineering order references that exact spec.

The Bottom Line

Both tapes are flame retardant double-coated cloth carpet tapes that meet Boeing BMS 5-133 and FAR 25.853(a). The substitution is direct. Where they differ: the 108FR is typically lower cost for the same core spec, is designed for clean repositionable removal, enumerates a broad multi-airframer approval set, and ships with a free lot-specific Certificate of Conformance. The P-55 counters with higher initial adhesion and its documented Airbus ABS 5648A approval. For mixed Boeing/Airbus interior work where cost and documentation depth matter, the 108FR is the stronger everyday choice.

Polyken 108FR specifications from the Vybond (Polyken) product data sheet. Nitto P-55 / P-55B specifications from the Nitto P-55 product data sheet; Nitto's current online aerospace specification list emphasizes Airbus ABS 5648A. Always verify current approval status against the applicable Boeing BMS, Airbus ABD/ABS, or OEM specification revision in force at time of purchase. Substitution on any specific aircraft program is the operator's or MRO's engineering decision against their approved parts list.
