Test Tools for Plastics

We have developed special test tools for many important standards in the plastics industry. Here you can find a small selection for: puncture/penetration tests on films, flexure tests, tools for testing the coefficients of friction (COF), determination of compression set, peel tests on adhesive tapes and peel tests on composites.

Ball burst test fixture

  • Applications: For tests to ASTM D3787-88, ISO 3303 Method A and ISO 9073-5
  • Specimen material Film, rubber, or plastic coated fabrics
  • Advantages: Fast, easy, reliable insertion of film strips

Test fixture for determining puncture resistance

  • Applications: The puncture tester determines the puncture resistance of packaging films to DIN EN 14477
  • Specimen material Packaging films
  • Advantages:
    • Fast, easy, reliable insertion of film strips
    • Endless strip specimens can be gripped quickly and securely.
    • The test probe is mounted in a collet, which makes it easy to remove it.
    • Round exchange jaw inserts (Vulkolan or O-ring against steel) are available for specimen gripping (included in the scope of supply). The opening and closing of the jaws, as well as gripping force application are carried out mechanically via a tightening nut.

 

Fixture for testing the frictional properties of plastic films

  • Applications: For determination of the static and dynamic coefficient of friction to ISO 8295, ASTM D1894, ASTM D2534, TAPPI T549, TAPPI T664 su64 and DIN 53375 (withdrawn)
  • Specimen material Plastic films, paper, board
  • Function description: The test fixture can be used to determine the frictional behavior between foils, as well as between a foil and sheet material (stainless steel or glass).

    A film is clamped on the carriage. A second film can be clamped to the stainless steel test table or onto the included glass plate, which is placed on the stainless steel table.

Fixture for testing the frictional properties of paper, board and plastic films

  • Applications: tests to ISO 8295, ASTM D1894, ASTM D2534, TAPPI T549, TAPPI T664 su64 and DIN 53375 (withdrawn)
  • Specimen material: paper, board, films
  • Advantages: Adhesive coating on friction block to grip specimen
  • Function description: The test fixture can be used to determine the frictional properties of paper, board and films. One specimen is attached to the carriage. A second specimen is clamped on the stainless steel plate.

Tests on natural rubber and elastomers to ISO 815 and on flexible foams to EN ISO 1856

  • self-contained instrument for determination of compression set
  • Specimen material:
    natural rubber, elastomers, flexible foams

Peel tests on composites

Adhesion tests of layers to DIN 53357 Method B (withdrawn), DIN 55543-5 and similar test methods

  • Specimen material:
    Plastic film and sheeting

90° peel test kit

The 90° tape peel test kit makes it possible to perform adhesion tests on adhesive bonds with stiff substrates (3 ... 50 mm thickness) and a flexible top layer (0 ... 20 mm).

The top layer is peeled off upwards over a deflection roller at a 90° angle. A further roller secures the guide for the stiff substrate to the sliding surface table. The axial force application in the tensile direction is ensured by these two rollers.

90° peel test kit FINAT

The 90° peel test kit enables comparison of the removabiity of materials. The carriage with specimen holder can move freely in the horizontal direction during the test.

The carriage is tracked via a steel wire.

180° peel test kit

The peel test kit for insulating tapes determines the tensile behavior of insulating tapes.

1026

Device for positioning and tracking flexible specimens

180° peel tests to determine adhesive forces (seal strength test)

1057

Tack loop test for testing the adhesive strength of adhesive tape

Testing adhesive strength during peel-off from a flat plate: test strips are separated from interchangeable glued plates to determine initial grab or tack, for example as per Finat test method No. 9.

  • Specimen material:
    adhesive tape

Interesting applications

3-point flexure test on plastics (ISO 178 and ASTM D790)

3-Point Flexure Tests

ISO 178
The 3-point flexure tests described in ISO 178 and ASTM D790, demonstrate classic characterization methods for rigid and semi-rigid plastics. Typical test results include the flexural modulus, stress at 3.5% elongation, stresses and elongations at the yield point and at specimen break.

Puncture test EN 14477, ASTM F1306 also known as Parker Ball-Point Test

Puncture Resistance

EN 14477, ASTM F1306
Puncture resistance is important when films are used as packaging material, for example, for food or parts with sharp edges. It is described in the following standards: EN 14477, ASTM F1306.

Static and dynamic friction behavior of films COF with zwickiLine materials testing machine and test fixture

Coefficients of friction COF

ISO 8295, ASTM D1894, JIS K 7125, DIN 53375
The COF provides information about the surface structure and printability. The static and dynamic coefficient of friction is particularly interesting for films that are further processed on packaging and printing machines.
