About Polyimide
Polyimide is a polymeric plastic material, engineered for long term performance at very high temperatures, in excess of 250°C for prolonged periods of time. It is thermally very stable, and is widely used in aerospace, electronics, and electrical industries when a high temperature material is required.Because of its thermal stability, properly engineered polyimide films do not shrink or decompose at the temperatures encountered in the circuit board industry. This is particularly important for bar code symbols. Shrinkage in the label will result in distortion of the bar code symbol, which makes it unscannable.
We carefully and continually evaluate properties of these films to maintain the highest quality standards in the industry today. We are the technology leaders in the use of polyimide chemistry and polyimide films for bar code applications.
Description
It is a special white coated 0.5mil polyimide film with a high temperature permanent pressure sensitive acrylic adhesive.
Properties
0.5 mil White Coated Polyimide Film material is intended to be used in harsh environments, including applications that require an ultra thin material.This material is designed to be used in harsh environments and can be printed with thermal transfer or flexographic ink systems to produce bar code, graphic, or text information. When printed with the appropriate thermal transfer ribbon, this material is resistant to chemical exposure.The durable polyimide film and special pressure sensitive adhesive is designed to withstand high temperature exposure up to and exceeding 150C. Minimal discoloration and shrinkage will result when exposed for prolonged periods at this temperature.
Applications
It is an ideal material for the following applications:
Tracking labels for mobile hand held devices.
Electronic product identification labels.
High temperature label applications where dimensional stability is critical.
Small label applications that require high resolution printing.
IC labeling for work in process, permanent ID & warranty labeling.
Product ID, asset tracking.
Low profile label applications where label thickness is an issue.
Special Considerations
The surface that you want to label should be clean, dry and free of any surface contamination, such as dust, oil or rust. Isopropyl alcohol is a recommended solvent to clean the surface.
When you apply the label, you must use firm pressure to increase the physical contact of the adhesive with the surface of the product.
On a warm surface, the adhesive will ‘flow’ more readily and increase adhesion,as compared to a colder one.
The top coat & print should not be contacted while exposed to elevated temperature.
All values shown are averages and should not be used for specification purposes.
Film thickness, adhesion and tack values have a 15% tolerance allotted to the values stated.
What we can offer
Comparison of Different Label Material
Label Material | Operating Temperature F (C°) | Short-term Temperature F (C°) | Benefits |
Vinyl or PolyVinyl Chloride (PVC) | 165° (74°) | General purpose film; excellent moisture, solvent, abrasion & smudge resistant and outdoor durability. Flexible, tamper evident, flame retardant; available in various colors. | |
Polystyrene | 175° (79°) | Thermoplastic with hard, rigid surface. Material is unaffected by moisture; typically used on timber tags- stapled to the end of finished timber. Also available in a brittle tamper-evident version. | |
Polyolefin | 200° (93°) | Low cost synthetic, commonly used for general purpose and economy label solutions. Better solvent/chemical resistance than paper. Used mostly in indoor applications | |
Paper | 212° (100°) | Typically less expensive than film, provides limited resistance to moisture, temperature, and chemicals. Generally used for short-term indoor applications | |
Tedlar (or PVF, Polyvinylfluoride) | 225° (107°) | 375° (191°) | Has excellent flame retardant properties, as well as extraordinary resistance to UV. Highly chemical resistant and expensive. Widely used in wire and cable marking applications |
Polycarbonate (Lexan) | 250° (121°) | Low temperature material, used in network identification and is a flame retardant material. | |
Polypropylene (PP) | 300° (149°) |
| Excellent substitute for Vinyl labels. Hard & rigid to the touch. Stretches in only one direction. Designed for 6 months outdoor exposure. Resistant to blood, alcohol and oils. |
Polyester (PET) | 325° (163°) | 400° (204°) | Tough, high performance film provide excellent outdoor durability, chemical & heat resistance. Displays excellent dimensional stability and high tensile strength. Popular applications include rating plates and fixed asset identification.. |
polyethylene naphthalate (PEN) | 400° (204°) | Moderate stiffness, stretches in all directions, but will tear quite easily. Designed for 6 months outdoor use. Useful for labeling products that expand and contract. | |
Polyetherimide | 450° (232°) | 500° to 550° | High temperature & chemical resistance, superior tensile strength and tear resistance. Unaffected by process used in PCB application. Recent problem with availability |
Polyimide | 500° (260°) | 750° to 1000° | Polyimide,Very tough material, provides highest level of performance to meet the most challenging applications. Extremely high temperature & chemical resistance, superior tensile strength and tear resistance. |
Aluminum Foil | 700° (371°) | 1112° (600°) | Long term heat exposure, alternative cheaper label construction for high temperature solutions |
Ceramic | 850° (454°) | (1400°) | used for extreme applications where conventional labels are not durable enough. |
We offer a wide variety of top coats designed to provide ideal printing surfaces for labels and printed electronics. In addition, the top coats can withstand high temperatures, harsh cleaners and solvents typical of the PCB manufacturing process. We also offer antistatic top coats that help safely dissipate static charges and provide low peel voltages during liner removal.
Our top coats include,
About Label Adhesives
Selecting the proper adhesive is essential to the success of the label in each application. Our adhesives are formulated to withstand harsh chemical and solvent attacks in the most hostile process conditions. A wide variety of acrylic adhesives are available, each in different thicknesses, to achieve a wide range of tack, shear and peel properties. Different adhesive thicknesses can be used to better match unique requirements, such as open, porous surfaces (thicker adhesive works better), or a 'low profile' surface (thinner adhesives needed). Labels exposed to higher temperatures than acrylic adhesives can tolerate will need silicone adhesives to 'do the job'. Silicone adhesives are also used whenever a label must adhere to a low energy, rough or porous product surface. Specific applications which require flame retardant adhesives, tamper-evident constructions, or removable and repositionable adhesives are also available for specific requirements, upon requested.
The release liner is the base layer of all our single and double coated tapes and label materials. Its primary function is to protect the acrylic and silicone pressure sensitive adhesive (PSA) until the tape or label is ready to be applied. The liner also helps in material handling, determines the ease of which the liner is removed from the PSA and is a critical element of the die cut process.
The liner is comprised of a carrier paper, polyester (PET) or fluorinated PET and an ultra thin layer of silicone. The percentage of silicone determines the release value with the higher percentage of silicone producing a lower release value and an easier release of the liner from the PSA. Release values are typically in the 20 to 50 pound range with the combination of carrier (material, thickness, etc.) and release value chosen based on the requirements of the die cut process.
