A compression test helps to measure the performance of materials such as corrugated boxes, heavy boxes, fiber boards, heavy boxes and many more which are kept under heavy weights. In the test procedure, the test samples are compressed using heavy loads and the pressure at which the material deforms recorded at different loads. The tension or compression on the material hence calculated and graphically represented format which is known as stress tension diagram. This representation helps to...

Three conditions can stimulate the corrosion including moisture, metallic surface and an electron acceptor. Removing any one of these conditions can stop the corrosion process. Metals can be protected by applying a negative charge or applying a coating or anodizing. One of the useful procedure is coating a metal surface with paint or enamel providing a barrier between moisture and metal. The coating disallows direct contact with humidity and metal surface. The salt fog cabinets are used to...

The PET bottle is the most preferred packaging item for the food industry for carbonated soda and juices. The PET bottles can be completely recycled. The PET bottles and jars are beneficial to increase the shelf life.

It is vital for paper & packaging manufacturer to understand the purpose and standard operating procedure of Cobb sizing tester for quality assessment of paper or corrugated fibreboards.

Light transmission property of the plastic films and rigid plastics are quite difficult to measure and define. As per the current terminology, the materials comprise with the terms such as clarity, total transmittance, transparency, diffuse transmittance, see through resolution distance, opacity, turbidity, haze, translucency, hiding power, etc. In addition to this, several types of measurement are done using the transmission detecting testing devices. The part of the transmission light is...

ASTM D412 - 06a Standard Test Methods The ASTM D412 – 06a test methods include the procedures to measure the tensile properties of the vulcanized thermostat rubbers and thermoplastic elastomers. The standard cannot be used for low elongation materials and includes Test Method A for dumbbell and straight section specimens and Test Method B for cut ring specimens. The test result of both methods is not identical.

The ASTM D429 includes the test procedure to determine the adhesion of rubber to rigid metal substrates. The vehicle engine mounts, rubber coated metal components, and rubber lined tanks and containers, use the ASTM D429 standard. The testing procedures include peel strength or tensile strength of the adhesion edge.

Purpose of Melt Flow Index Test Melt Flow Index Test is a very simple method that helps to characterize the flow properties of the melted plastics. This test method is widely used for the quality assurance purposes and raw material resting. This test can be performed using high-quality of Melt Flow Index Testers. The demand of the extrusion plastometers such as Melt Flow Index Tester varies as per the requirement arises for different applications in various plastic industries. Presto...
