RS-8226 Tape Tack Rolling Ball Tester

RS-8226 Tape Tack Rolling Ball Tester

The RS-8226 Tape Tack Rolling Ball Tester is designed for testing the adhesiveness of various tapes. Place the sample with the adhesive side facing upward on a 30° inclined plate, fix both ends with tape and weights respectively. Then take steel balls starting from the largest size, let them fall freely from the inclined plate in sequence, and record the ball number that can adhere to the sample for more than 5 seconds.

The RS-8226 Tape Tack Rolling Ball Tester is designed for assessing the initial tackiness of a wide range of adhesive tapes. During the test, tape samples are placed adhesive side up on a glass incline set at an adjustable angle (commonly 30°). Steel balls of gradually decreasing size are rolled from the top of the inclined plate; the largest numbered ball that sticks to the tape for at least 5 seconds is recorded as the tack value.

The tester accommodates up to four samples simultaneously and comes with 32 precision steel balls ranging from 1/32" to 1" in diameter. The adjustable inclined angle (20°–40°) allows flexible testing conditions, while the glass test plate ensures a smooth and consistent surface for accurate evaluation. The RS-8226 is built according to GB/T4852 and CNS11888 standards, ensuring reliable and comparable results.
