Scenario: You are working on a project to develop a new seal for an oil well pump. The pump operates at high temperatures and will be exposed to corrosive fluids. You need to choose the appropriate elastomer for this application.
Task: Research different types of elastomers and their properties. Consider the following factors:
Write a short report outlining your chosen elastomer, explaining why it is suitable for the application, and the properties that make it a good choice.
Possible choices for the oil well pump seal include:
Your report should discuss the specific properties of the chosen elastomer and why they make it a good choice for the oil well pump seal application. For example, if you choose NBR, you could highlight its oil resistance, temperature range, and compression set properties. You should also mention any limitations or considerations for using this specific elastomer.
