Are you uncertain of what to look for when comparing material data reports for various elastomers? Ever wonder about the impact a seal’s durometer has in the application? Have you asked, ‘What is compression set and why is it important?’ These are the types of questions and concepts covered in the O-Ring Elastomers chapter of Parker’s O-Ring eHandbook.
The interactive component of eHandbook
Since its debut in 1957, the Parker O-Ring Handbook has become a fixture on the reference shelves of engineers and seal specifiers worldwide. According to Steven Weinzierl, Ph.D., Parker's Global e-Business Customer Support Manager, "Parker's O-Ring Handbook is one of the world's most complete reference books for everything and anything related to the technology and application of O-Rings. It is downloaded thousands of times a month from www.parker.com, making it one of Parker's most downloaded knowledge assets." By creating an interactive, digital version of this resource, Parker is expanding it's customer base and utilizing various forms of multi-media to provide visual explanations and demonstrations that further enhance an industry staple.
Relating properties to O-ring use
Seal manufacturers compile material data sheets of physical properties, compression set, and a myriad of other combinations of testing; all intended to demonstrate the seal material’s capability. But what are these characteristics, and how does one relate the results to an application?
The Physical and Chemical Characteristics chapter explains the lab testing behind each data point on a test report. Video snips of laboratory equipment testing O-rings illustrate how data is generated. Animations create a visual explanation of testing such as TR-10. Brief summaries of each characteristic explains how data can be applied to an O-ring in service. Photographs and vibrant charts help to put context around the data, in order to bring to light how each bit of information should be interpreted.
Perusing the Physical and Chemical Characteristic chapter will allow you to evaluate rubber test reports with a greater understanding than ever before.
Further subsections of the Material Selection Guide feature a compound family overview including a description of compound advantages, typical temperature maximum/minimum, and compatible fluids. A list of incompatible fluids is also detailed, allowing the user to receive a concise summary of the most common, and even the more obscure elastomer types.
