What is ASTM D3330?

Table of Contents

ASTM D3330 is one of the more popular testing standards to determine the adhesive strength of pressure sensitive tapes. This unique standard consists of Methods A through F, identifying ways to measure peel adhesion with 180 degree and 90 degree peel methods.

What is ASTM D903?

ASTM D903 is a common tensile test used to evaluate the peel or stripping characteristics of adhesively bonded materials used in a wide variety of applications in an even wider range of industries. Some examples of materials tested to ASTM D903 are plastic films, adhesive labels, and waterproofing materials.

How do you test a pressure sensitive adhesive?

The tape is applied to the surface with a defined amount of pressure and then allowed to remain on the surface for a controlled amount of time (often 20 minutes but tests using 24 hours, or more are also performed). After that time, the tape is peeled off using a machine capable of measuring the force needed.

What is pressure sensitive tape used for?

You can use it for plastic films, tissue, any nonwoven, and many other materials. Typically, you can find double-coated PSA used as laminate and carpet tape. To create double-sided tape, a company will coat two sides of a carrier material with adhesive.

What is 180 Peel Adhesion Test?

This procedure determines the adhesive strength of a specified sealant by peeling the sealant apart at 180°. The maximum peak load required to separate one layer from the other is reported in pounds per inch of width. The separating surface is under cut before pulling to promote adhesive failure.

How do I check my peel strength?

Peel strength is measured by means of a peel test. During a peel test the materials are pulled apart at a constant speed. The average force required to pull the materials apart is then used in conjunction with the width measurement of the bond to determine the peel strength.

How do you test adhesive?

Shear testing of adhesives generally involves a single or double lap joint and a universal shear testing machine. The adhesive is applied to the joint between the two materials so that one continuous length is formed. The two ends of the new sample are then placed into their respective grips in the shear tester.

How do you perform a peel test?

Common Peel Tests: The T-peel test is a type of tensile test performed upon two flexible substrates that have been bonded together and placed into peel test grips such that one substrate sticks up and the other sticks down while the bonded area sticks out horizontally so that the entire setup forms a “T” shape.

How long does pressure-sensitive adhesive take to dry?

Up to 8–10 hours. High temperature and low humidity will cause the adhesive to cure faster. After installation, restrict foot traffic and moving of heavy objects for 24–48 hours to allow adhesive to cure properly.

Which type of peel tester is available in our lab 90 degree 180 degree?

Peel tester is widely used for evaluating the peel strength of Self-adhesive tapes, BOPP tapes, etc. Computerized peel tester offer a number of robust features. 180 degree as well as 90 degree angle test will be available. Has single speed test of 300 mm/min.

How is peel strength calculated?

Calculate the peel strength by multiplying the average load by 9.81 to convert to Newtons and divide by 25mm/1” [or the peel strip width in mm if appropriate] to give the peel strength in Newton per millimetre width [N/mm].

What is a high peel strength?

Master Bond has developed a wide variety of one and two component high peel strength adhesives for challenging bonding applications. Peel strength can be described as a material’s ability to resist forces that can pull or peel it apart at a predetermined angle and rate.

What is the unit of peel strength?

Peel strength is reported as the peel force divided by the specimen width, such as g/25 mm.

How is adhesive strength calculated?

Adhesive bond strength is usually measured by the simple single lap shear test as shown in Fig. 9. The lap shear strength is reported as the failure stress in the adhesive, which is calculated by dividing the failing load by the bond area.

What is the ASTM d3330 test?

ASTM D3330 Test Method A measures the peel adhesion of single-coated adhesive tape, when peeled at a 180 degree angle. The purpose of ASTM D3330 data results help assess the uniformity of adhesion for pressure sensitive tapes.

What is the best Peel grips for ASTM d3330?

The G240k Mechanical Vice Peel Grips are a popular option for testing to ASTM D3330. These simple and effective grips have 30mm wide jaws, perfect for the majority of sample sizes. Another option for customers testing smaller samples are the G227 Mechanical Vice Peel Grips.

What are the different types of ASTM tests?

How do you test a 90 degree tape?

Test Method F – Single Coated Tapes at 90 Angle. Adhere the specimen to the testing plate (use a roller to eliminate air bubbles). Fold an end of the specimen to create a tab. Fold back the tab to a 90 degree angle and connect it to the grip. Begin peeling the tape at a 90 angle. Record the average force required for peeling.
