Coefficient of Friction Testing

Slide Angle Friction is a measurement of a sheet like substrate such as paper, corrugated, plastic film or paperboard that determines the angle of inclination at which one substrate affixed to a sled will begin to slide/slip against another substrate of a similar material.

During a test, an inclined plane is increased at a rate of 1.5 ± 0.5º per second by an electric motor until the test block begins to slide. The initial movement of the sled is the Slide Angle or Coefficient of Static Friction of the material. When the test block just begins to slide a photo-optical sensor automatically stops the inclined plane and the operator can read the slide angle result.

A variety of factors can affect the Slide Angle measurements including abrasion, coating, varnishes, printing and most importantly humidity.

Cobb Testing

Water absorptiveness of paperboard or other materials is a function of various characteristics such as sizing, porosity, etc. The Gurley-Cobb sizing test can be used to test absorption or resistance of water, oil and other liquids.

Trial Assistance

Trials are a critical step in the success of any project and Jain Chem’s philosophy is to work intimately with customers to assure that all variables are considered before a trial investment is made. Our team of chemist’s and engineers are trained to understand how Ulterion® brand products respond to different process conditions and work with customers to develop trial plans that meet performance objectives. Our goal is to help our customers in every way possible to make every trial a success.

Air Permeability Testing

Jain Chem uses Gurley Densometers that are the accepted standard for measuring the porosity of materials such as papers, textiles, plastics and membranes. All Densometers measure the time required for a given volume and of air (25cc to 400cc) to flow through a standard area of material being tested under light uniform pressure. Conform to TAPPI T-460, ASTM D-726-58 & APPITA/AS 1301-420, BS 5926, CPPA D-14, ISO 5636/5, D-202-77, SCAN P-19 & P-53.

High Pressure Densometers are the accepted standard for measuring the porosity, air-permeability or air-resistance of materials having low permeability. Typical materials include coated papers, plastics and membranes. High Pressure units are recommended whenever a standard unit would yield excessive measurement times. Conform to TAPPI T-536-88 and ASTM D-726-58, Method B.

Laboratory Evaluations

Jain Chem provides laboratory services to help customers choose the optimum product for a particular need or application. It all starts with developing a project profile so that all aspects of our customer’s application are considered. It is important that substrates, final properties, the process used and cost targets are all considered before an evaluation can proceed. Jain Chem continues to invest in resources to help our customers make the best selection possible for their particular application.

Trained Jain Chem technicians take pride in carefully considering all product options to meet customer objectives. After thorough laboratory evaluations our laboratory staff will review all data and develop detailed reports and trial options for our customers to consider.

Product Development & Modification

From time to time an existing product may require some adjustment in property to meet a performance standard or adapt to a process. Jain Chem researchers work diligently when necessary to find a formulation adjustment to make a product perform successfully. Many of our products are 2nd or 3rd generation developments that have allowed customers to move forward with success.
