Standard model VPA-H200 &
Compact model VPA-H100

Pressure-sensitive adhesive tapes, or PSA tapes, play significant roles as constitutive and integral parts of production processes in various forefront industries such as flat panel displays, semiconductors, optical instruments, solar batteries, automobiles, architecture, and medical treatments.

The peel adhesion, shear resistance, and tack tests characterize the performance of PSA tapes. The widespread peel adhesion test delivers an objective appraisal with quantitative evaluation following international standard ISO 8510-1 and 2, the 90º peel test, and the 180º peel test. The 180º peel test tends to be affected slightly by the thickness and elasticity of PSA tape, and the 90º peel test may experience elongation and sagging of PSA tape due to the somewhat complicated structure of the jigs.

Demands on peel adhesion, peel angle, and peel rate for optimizing adhesive tapes used in production processes vary widely depending on the applications.

KYOWA’s patented Flat Plate Cross Stage Method

The flat specimen stage sits on a rotary table, with which the peel angle can be simply and swiftly adjusted from 0 to 180º without using any jigs or tools. The employed synchronized actuator mechanism enables to maintain the same peel rate and peel angle during the stage travel. No complex adjustments and calculations are required.
