What is peel strength testing & Its Uses?

 


The strength required for peeling two materials is measured by a machine which is commonly known as a peel/seal/bond strength tester. It is most commonly used in the adhesive and packaging industries. A force is applied on the bonded surface with this tester by separating the materials. 

Moreover, it is also helpful in understanding the adhesive strength and quality of a bond. 

The main purpose of the peel strength tester is to measure the load applied to separate bonded materials. 

A Peel strength tester is used because it is the best way to characterize adhesive bonds. 

Moreover, it is performed at an angle of 90-180 degrees.

What is the use of a peel tester?

Effective Lab India peel bond tester is used for several purposes in different industries. Let us tell you some of its uses in different industries.

Packing industry: In the packaging industry, it is used for evaluating the strength of seals on packages. These packages are maybe bags or pouches. It ensures the strength of packaging during transportation or storage.

Research & Development: In the research and development industry, it is used for evaluating new adhesive materials. Moreover, a peel-strength tester is used in developing innovative products. 

Manufacturing industries: For assessing the bonding strength of products, a peel tester is used. It includes plastics, tapes, films and adhesive. Manufacturers can determine the durability and strength of their products with the help of this tester.

Adhesive: In testing the adhesive properties of different materials, a peek strength tester plays an important role. 

Overall, it is a useful tool for determining the strength, durability and quality of different products across various industries.

What is the peel strength method?

The working method for a peel/seal/bond strength test is very simple and easy. 

First clamp the bonded materials on the tester.

After clamping, a force is applied to the bonded material. (This force is perpendicular and it peels the material).

After that, the force required for separating the materials is measured. 

Hence, the force used to peel the materials is termed peel strength.

Manufacturers can measure the strength of their adhesive bonds with the help of accurate measurements provided by this tester.

What is the ISO test for peel strength?

The ISO test for peel strength involves ISO 11339:2010 which evaluates the peel strength of a material by T-peel test. Design information is not provided in this test procedure.

This test is developed for testing metal adhesives while other adhesives can also be tested with this method.

How do you calculate peel strength?

In a peel bond strength tester, the peel strength of materials is calculated by weighing the specimen, averaging the load, and dividing the result by the bond line’s unit width. However, the load data is derived from the flat portion of the load.

Industrial Product Protection Using UV Weathering Test Chambers

Image
  Imagine spending months creating a ground-breaking product, only to have it fail due to the inclement weather. For any producer who relies on materials exposed to sunlight and the environment, cracks, fading, and warping are nightmares. According to its ability to simulate environmental pressures and forecast real-world performance before a product is exposed to sunlight, UV weathering test chambers act as obedient guardians. This is an outstanding instrument for laboratory testing apparatus used to evaluate the polymers' actual endurance under various weathering scenarios. This uv light accelerated weathering tester makes it simple to imitate weathering conditions and assess the quality of polymers. What is meant by a UV Weathering Test Chamber? Consider it a material testing machine. By simulating the impacts of temperature, humidity, and sunlight, this specialised chamber speeds up the ageing process that occurs naturally. Strong UV lamps simulate the spectrum o

Why Do You Need To Run A Box Compression Test?

Image
  A tool specifically designed to measure the compressive strength of corrugated cardboard boxes or containers is called a Box Compression Tester . It is made up of a strong frame with a compression plate on top. A box compression tester's main purpose is to push a box that is set on the compression plate until it collapses or deforms. This makes it easier to figure out the highest load the box can support before breaking.  Effective Lab India box compression test machine usually consists of a digital display that shows the results, a hydraulic or pneumatic system that applies regulated pressure, and load cells or pressure sensors that measure the force applied to the box. Why Conducting a Box Compression Test to Assess Strength To assess the robustness and longevity of corrugated cardboard boxes or containers, a box compression test is performed. This is the importance of it as follows: Quality Assurance: By confirming that the boxes fulfil the necessary requi

What is the standard Used for salt spray testing?

  You care most about your fasteners’ ability to perform their intended functions even in the most adverse conditions. Professional companies trust salt spray testing when they want something durable. Since fixing rusted fasteners can be costly and dangerous, these enterprises rely on the results of  salt spray testing . One technique for evaluating the corrosion resistance of materials and coatings used in the production of items that resemble fasteners is salt spray testing. Salt spray testing entails accelerating the corrosive attack to get a better picture of how well the coating will shield the metal. The objective of salt spray testing . The usual objective of salt spray testing is to quickly compare the corrosion resistance that is expected and what is there with a  salt spray chamber . There is not much of a correlation between the lifetime of the studied coatings and their actual expected life. This is the case because corrosion is not a straightforward process an
