• the halogen- free flame retardant composition is blended or combined with an adhesive material. Because of the general desire to minimize or eliminate halogenated materials from commercial and consumer products, the adhesive materials into which the flame retardant compositions are incorporated are preferably also substantially free of halogen-containing compounds.
• Useful adhesive compositions include myriad different types and forms of adhesives.

• the backing can be of any desired and workable thickness, but is generally between about 25 ⁇ m and about 125 ⁇ m thick.
• a specimen is exposed to an open flame for a period of fifteen seconds. Upon exposure to the flame, any flame on the test specimen (which typically catches fire) must extinguish in less than 60 seconds to pass the test. The test is repeated five times. Any extinguishing time longer than 60 seconds is considered a failure for the specimen. Results are reported as "Pass” or "Fail.” Further information regarding the test may be found in the description of the UL 510 standard published by Underwriters Laboratory of Northbrook, Illinois, USA. 2. Dry and Wet Dielectric Strength:
• Testing for dry and wet dielectric strength was performed according to the protocol of ASTM D149. In general, according to this test a sample is placed between two electrodes and power is increased until there is a dielectric failure. Testing for "dry" dielectric strength was performed at room temperature and 50% relative humidity.
• CTI Comparative Tracking Index
• the Comparative Tracking Index (or "CTI") of a material is a measure of the resistance of a material to surface tracking under defined test conditions.
• the protocol for the test is set forth in ASTM D3638-07.
• to perform the test the upper surface of a test specimen is supported in an approximately horizontal plane and subjected to an electrical stress via two electrodes.
• the surface between the electrodes is subjected to a succession of drops of an electrolyte solution until the over-current device operates, until a persistent flame occurs or until the testing period has elapsed.
• Individual tests are of short duration (less than 1 hour) with up to 50 or 100 drops of about 20 mg of electrolyte solution falling at 30 second intervals between platinum electrodes spaced 40 mm apart on the test specimen surface.
• An alternating current voltage between 100 V and 600 V is applied to the electrodes during the test.
• Results are plotted to record the number of drops of electrolyte solution placed on the surface of the specimen versus the recorded voltage.
• the Comparative Track Index, or CTI represents the voltage corresponding to 50 drops of electrolyte solution. The lower the CTI rating for a given material, the greater is the creepage distance associated with that material.
• a CTI Rating is given as follows:
• CTI Rating I CTI > 600 V
• CTI Rating II 400 V ⁇ CTK 600 V
• Opacity was tested according to ASTM D589-97. In general, to perform the test a film sample is placed on a black/white contrast chart. After air-drying, the drawdown of a sample is objectively evaluated using a BYK-Gardner type spectrometer guide. Results are reported as percent opacity, calculated as: Y Bl ac k / Yw h ite X l00%
• Tape samples were constructed to illustrate the performance of several known flame retardant compositions.
• an acrylic adhesive polymer (3MTM Product No. 21-3314-0004-0, from 3M Company, Saint Paul, Minnesota, USA) was combined with a flame retardant composition as indicated in Table 1 below.
• the mixture comprised between 30 and 40 wt% of the flame retardant.
• the ingredients were mixed using a laboratory-size high intensity mixer in the presence of a solvent (heptane, ethyl acetate or a blend of both).
• the mixed adhesive composition was coated directly onto a primed 25 ⁇ m thick PET film using either a laboratory knife-coater to produce handspread samples or a pilot-size coater (equipped with a knife-coater) to produce a continuous coated film with a nominal coating thickness of about 25 ⁇ m.
• the samples were either placed in a forced-convection oven (in the case of the handspread samples) or continuously passed through a tunnel oven (in the case of the continuous film) to extract the solvent and dry the sample.
• the coated and dried samples were then cut or slit to produce 0.75 inch (1.9 cm) samples.
• Table 1 Table 1
• Tape samples were constructed to illustrate various embodiments of the invention.
• an adhesive composition was prepared containing the ingredients identified in Table 2 below in the amounts identified in Table 3.
• the ingredients for the adhesive composition were mixed using a laboratory-size high intensity mixer in the presence of a solvent (heptane, ethyl acetate or a blend of both).
• the resulting composition was coated directly onto a primed 25 ⁇ m thick PET film using either a laboratory knife-coater to produce handspread samples or a pilot-size coater (equipped with a knife-coater) to produce a continuous coated film with a nominal coating thickness of about 25 ⁇ m.
• the samples were either placed in a forced-convection oven (in the case of the handspread samples) or continuously passed through a tunnel oven (in the case of the continuous film) to extract the solvent and dry the sample.
• the coated and dried samples were then cut or slit to produce 0.75 inch (1.9 cm) samples.
• the samples were subjected to the test methodologies described above and the results are indicated in Table 3 below.
• Flame retardant compositions that include both a phosphinate and alumina trihydrate at a ratio of less than about 17% phosphinate by weight of the flame retardant composition require higher levels of the blended flame retardant to be present in the adhesive composition to achieve a desired level of flame resistance. This generally negatively affects the adhesive properties of the adhesive composition and are therefore not preferred.
