Rheology test helps packaging industry find the best adhesive

Prior to the purchase of high-performance adhesives, paper processing companies often conduct some rheological tests to ensure that the materials are applied well and that the processing equipment runs smoothly. Rheological analysis of adhesives eliminates skepticism about whether mass production can occur.

During the processing of paper products, a fully equipped rheology laboratory can help adhesive users and suppliers to detect the elasticity, fluidity, and other properties of adhesives, thereby minimizing development risks. Therefore, paper product processing companies can maximize their productivity while improving quality.

Rheological analysis is a valuable service for paper processing companies and their end users. Investing in adhesive suppliers for sensitive rheometers can also streamline their production lines, improve product reliability and stability, and optimize the performance of adhesives.

By studying the fluidity of the adhesive, the experimenter was able to figure out how an adhesive works and penetrates into different materials.

For example, some paper product processing companies need adhesives that have very reliable performance in ultra-high temperature or ultra-low temperature environments. Highly sensitive rheometers can simulate production processes, coating properties, and adhesive performance in a variety of large-scale process production processes.

The adhesive company's RDAIII, two ARES, and three other rheometers ensure that the adhesive's elasticity can be measured at temperatures from -150°C to 600°C (-38°F to 1112°F). A well-known computer printer manufacturer had wanted to know whether a pressure-sensitive adhesive could provide strong and reliable adhesion at 200°C to 300°C (392 to 572°F). A state-of-the-art rheometer installed a few years ago can provide data to answer customer questions.

Several rheometers are connected, ensuring that the rotation rate and the adhesive's ability to withstand harsh conditions are recorded. All rheometers work with versatile custom software.

The rheometer's spin rate can be very slow, and it can take 30 years to complete a full week. Rheometers have good sensitivity and recording capabilities. TheNation al-Bureau of Standards has installed a rheometer that is as advanced as the National Adhesives Association and has been in use for nearly a year now.

Although advanced rheometers are very important, this is not yet a complete solution. In addition to having fully equipped laboratories, the people working in this laboratory know about simulations of an application, materials science, adhesives, and polymer chemistry.

Some scientists use spectroscopy, electron microscopy, and other equipment to perform research under molecular and atomic conditions. With a large number of advanced tools, scientists are likely to conclude that without considering temperature, what can increase the strength and flexibility of adhesives and what not.

The test procedure must fully comply with the ISO9000 series requirements. This is very important for some U.S. customers and all European customers. The rheological laboratory of the National Adhesives Association had only one rheometer 15 years ago. It has shown extraordinary practicality in developing new products and solving problems, so that the company quickly realized that rheological research is the key to meeting the requirements of paper processing companies and providing advanced products to maintain its leading position.
