Test for Peel Strength

Test for Peel Strength
This Standard applies to the determination of peel strength of all kinds of soft and rigid composite
plastic materials which are composites on plastic or other base materials (such as aluminium foils
and paper).
Peel strength refers to the average peel force of composite layer and base material measured by
carrying out TT-type peeling on a specimen of specified width at a certain speed.
Method for determination
Take an appropriate amount of specimen; remove 50 mm in the width direction at both ends of
specimen; cut 5 specimens of horizontal width, lateral width 15.0 ± 0.1 mm apiece and length
200 mm. The composite direction is the longitudinal direction. Specimens shall be stored for 4 h
in the environment of temperature 23°C ± 2°C and relative humidity 50% ± 5%, and tested under
such conditions.
First peel 50 mm of composite layer and base materials at one end along the length direction of
specimens. The peeled part shall have no visible damage. If it is hard to peel specimens, about
20 mm of one end of specimens may be immersed in an appropriate solvent (usually ethyl acetate
and acetone) for treatment; after the solvent is fully evaporated, the test for peel strength may be
carried out.
If composite layer is not separated from base material through the treatment of the above-
mentioned method, the test shall not be continued and the material is determined to be not
peelable.
Fix both ends of the peeled part of specimens to the upper and lower clamps of tester, to make
the vertical axis of the peeled part of specimens coincide with the centre line of the upper and
lower clamps, with appropriate tightness. During the test, the unpeeled part and the tensile
direction form a T, see Figure 1. The test speed is 300 mm/min ± 30 mm/min. Record the peel
force curve during the peeling process of specimens.
Test result
Refer to the three typical curves of Figure 2; take an applicable method for evaluation; calculate
the average peel strength of each specimen. Calculate the arithmetic mean value of the
longitudinal and lateral peel strength of each group of specimens as the test result; take two
significant digits, expressed in N/15 mm.
If composite layer is not peelable or composite layer ruptures, its peel strength passes the test.

Test for Peel Strength
This method applies to plastic composite in plastic or other substrates (such as aluminum boxes, paper, etc.) on a variety of soft, hard composite plastic material
Determination of peel strength.
The peel strength refers to a sample having a predetermined width, and T-type peeling at a constant speed, and the measured composite layer
With the average peel force of the substrate.
Determination of the amount of sample to take the sample width of the direction of both ends to remove 50mm, even cutting longitudinal, horizontal width of 15.0mm
± 0.1 mm, and length of.200 mm. The composite direction is longitudinal. The sample should be at a temperature of 23 ° C ± 2 ° C
Humidity 50% ± 5% of the environment, placed more than 4 hours, and under the conditions of the test.
The composite layer and the substrate were peeled off by 50 mm in the longitudinal direction along the longitudinal direction of the sample, and the peeled portion was not significantly damaged. If
The sample is not easy to peel, can be about 20mm at one end of the sample immersed in the appropriate solvent (commonly used ethyl acetate, acetone) in the treatment
After the product was completely volatilized, the peel strength test was carried out.
If the composite layer is not separated from the substrate by the above-described method, the test can not be performed and it is judged that the composite layer can not be peeled off.
The two ends of the sample peeling part are respectively sandwiched between the upper and lower jigs of the testing machine so that the longitudinal axis of the specimen peeling part and the upper and lower clamp
With a center line coincidence, and loose straight. Test, the unclamped part and the tensile direction was T-type, see Figure 1, the test speed
For 300 mm/min ± 30 mm/min, the peel force curve during the peeling of the sample was recorded.
Test results with reference to Figure 2 three typical curves to take one of the similar value method, calculate the average stripping of each sa......
