Lowered Surface Friction for Elastomers
For elastomers, particularly O-rings, reducing surface friction is crucial for extending the lifespan and improving performance in dynamic applications. Lubricants like PTFE Teflon and silicone can significantly reduce friction, preventing wear and tear during movement. This reduction in friction not only enhances sealing capabilities but also reduces the force required for installation, making it easier to fit elastomers into tight spaces without damage.
