3M Extruded PTFE Film Tape [2 mil carrier] | SKU 5490
Before ordering, please read the "Product Description & Specs" tab content for more information about this item.
Product Description
3M 5490 Extruded PTFE Film Tape combines a 2 mil extruded PTFE (polytetrafluoroethylene) film carrier with a pressure-sensitive silicone adhesive. Together they create a smooth, slick, non-stick surface over a wide range of substrates, helping web materials and parts move freely in roll wrap and lay-flat applications.
Extruded vs. Skived PTFE
Extruded PTFE film is formed by pushing molten resin through a die, producing a flatter, more dimensionally uniform sheet than skived film, which is shaved from a solid PTFE billet. In practice that means 5490 resists curling as it comes off the roll and lays down more evenly across wide flat surfaces. Skived films are generally more conformable around curves and irregular shapes. If your surface is a flat plate, bar or wide roller, extruded is usually the better fit.
Key Features
- Extremely low coefficient of friction for smooth, non-stick performance
- Extruded carrier lies flatter than skived PTFE film and resists curling on unwind
- Thicker backing extends service life under abrasion and wear compared to thinner PTFE films
- Silicone adhesive removes cleanly from a wide variety of surfaces
- Excellent chemical resistance, with the exception of organic solvents
- Long term service range of -65°F to 500°F (-54°C to 260°C)
Recommended Applications
- Roll wrap for web processing on belts and plates where sticky materials and inks accumulate
- Easy-release surface on rollers, formers and slide plates to reduce friction
- Mold release for composite or metal bonding
- Chemical-resistant masking and sealing surface
- High temperature wire bundling and harnessing
- Lining of chutes, troughs and ducts
- Squeak, rattle and machine noise reduction on mechanical assemblies
Important Notes
The silicone adhesive is attacked by commercial organic solvents, so 5490 is not recommended where solvent resistance is required. For those applications, 3M offers a rubber-adhesive alternative.
Caution: Do not heat or expose PTFE film tape to temperatures above 600°F (316°C). Small quantities of hazardous vapors may be released, and inhalation may be harmful or cause respiratory tract irritation.
3M classifies this as an industrial and occupational product intended for trained workplace users. Country of Origin: United States.

Question & Answers
User Reviews
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
acrylic
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
silicone
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
Lower gauge gloves are heavier - have thicker construction, fewer stiches knitted per inch and offer less dexterity.
Higher gauge gloves are lighter - have thinner/finer construction, more stitches knitted per inch and offer more dexterity.
Gloves offered typically runs from 7 to 18 (12 and 13 are in the middle of the scale).
