6085-05
6085-05 is a PTFE-coated woven fiberglass tape with a high-temperature silicone adhesive, supplied at 0.0068″ overall thickness (0.0046″ PTFE-coated woven fiberglass substrate / 0.0022″ silicone adhesive). The combination of PTFE non-stick surface chemistry with a woven fiberglass reinforced substrate delivers dimensional stability, excellent tensile strength, and exceptional wear life suitable for heat-sealing machines, shrink-wrapping equipment, and sliding wear applications. Operating temperature spans −100°F to 500°F continuous. Peel adhesion is 48 oz/in of width with 6,000 V dielectric strength.

6085-05 is a light-gauge member of the 6085 PTFE-coated woven fiberglass tape family, constructed with a 0.0046″ PTFE-coated “E” Type woven fiberglass substrate and a 0.0022″ high-temperature silicone adhesive layer, for a 0.0068″ total nominal thickness.
The substrate combines two distinct material technologies: woven fiberglass provides dimensional stability, tensile strength, and reinforcement against tearing under load, while the PTFE coating provides the non-stick surface chemistry, low coefficient of friction, and chemical resistance that PTFE is known for.
The high-temperature silicone adhesive is the practical pairing choice — silicone PSA chemistry is the standard adhesive system that can withstand the 500°F service envelope without degradation.
Typical applications include heat-sealing machines, shrink-wrapping equipment, sliding wear applications, and any installation requiring a smooth non-stick surface combined with high wear resistance. The 6085-05 sits between the thin 6085-03 (0.005″ overall) and the medium 6085-06 (0.0077″ overall), offering moderately higher dielectric strength (6,000 V vs 5,000 V) and peel adhesion (48 vs 40 oz/in) at a small profile penalty.
Performance characteristics include 48 oz/in peel adhesion (nominal), 6,000 V dielectric strength, and a continuous operating range of −100°F to 500°F. The tan substrate color is characteristic of PTFE-impregnated fiberglass weave. Adhesive shelf life is greater than 6 months and less than 12 months.
What differentiates 6085-05 from other gauges in the 6085 family?
6085-05 occupies the light-mid gauge position in the family at 0.0068" overall thickness, with 6,000 V dielectric strength and 48 oz/in peel adhesion. It offers a balance between the very thin 6085-03 (0.005" / 5,000 V) and the medium 6085-06 (0.0077" / 8,000 V) — useful when the slight performance advantage over 6085-03 matters but the heavier substrate of 6085-06 is unnecessary.
Why is dielectric strength important when selecting this tape?
For applications where the tape contacts or insulates near energized components, dielectric strength sets the maximum voltage the tape can withstand before electrical breakdown. The 6,000 V rating supports use in moderate-voltage electrical assemblies, motor and transformer wraps, and similar applications. The PTFE-coated fiberglass construction also provides chemical resistance and non-stick characteristics not found in typical insulation tapes.
What is the operating temperature range for 6085-05?
6085-05 has a continuous operating temperature range of −100°F to 500°F.
Is 6085-05 suitable for chemical-exposed or non-stick high-temperature applications?
Yes. The PTFE coating provides broad chemical resistance and non-stick surface properties, while the high-temperature silicone adhesive maintains bond integrity across the full −100°F to 500°F range. No specific regulatory compliance standards are listed on the TDS for this material.
How should 6085-05 be specified?
Specify product (6085-05 PTFE Coated Woven Fiberglass), substrate thickness (0.0046" PTFE-coated fiberglass), adhesive thickness (0.0022" silicone), overall thickness (0.0068"), color (Tan), application category, dielectric requirements, compliance requirements, dimensional tolerances, and finished format.
