6085-03
6085-03 is a PTFE-coated woven fiberglass tape with a high-temperature silicone adhesive, supplied in the thinnest gauge of the 6085 family at 0.005″ overall thickness (0.0028″ 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 40 oz/in of width with 5,000 V dielectric strength.

6085-03 is the thinnest-gauge member of the 6085 PTFE-coated woven fiberglass tape family, constructed with a 0.0028″ PTFE-coated “E” Type woven fiberglass substrate and a 0.0022″ high-temperature silicone adhesive layer, for a 0.005″ 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 thin gauge of 6085-03 makes it suited for low-profile applications where a thicker tape would interfere with mechanism geometry.
Performance characteristics include 40 oz/in peel adhesion (nominal), 5,000 V dielectric strength, and a continuous operating range of −100°F to 500°F — among the widest thermal capabilities in the H-O catalog. 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 6085-03 from heavier gauges in the 6085 family?
6085-03 is the thinnest gauge at 0.005" overall, suited for low-profile applications where a heavier tape would interfere with mechanism clearances. As substrate thickness increases across the 6085-05, 6085-06, 6085-10, and 6085-14 grades, dielectric strength, peel adhesion, and mechanical robustness all rise — but at the cost of profile thickness. Select 6085-03 when minimum profile is the priority and 5,000 V dielectric strength is sufficient.
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 5,000 V rating supports use in low-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 6085-03?
6085-03 has a continuous operating temperature range of −100°F to 500°F.
Is 6085-03 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. The TDS explicitly identifies non-stick adhesive applications as a primary target use case. No specific regulatory compliance standards are listed on the TDS for this material.
How should 6085-03 be specified?
Specify product (6085-03 PTFE Coated Woven Fiberglass), substrate thickness (0.0028" PTFE-coated fiberglass), adhesive thickness (0.0022" silicone), overall thickness (0.005"), color (Tan), application category (heat sealing / shrink wrap / wear surface / electrical insulation), dielectric requirements, compliance requirements, dimensional tolerances, and finished format.
