Surface finish is a critical factor in polymer seal performance because it directly impacts sealing effectiveness, friction, and durability. Unlike softer elastomers which can conform to rough surfaces, most polymer materials are harder and require specific surface textures to create a reliable, long-lasting seal.   Key Reasons Why Surface Finish Matters: Sealing Effectiveness: A proper ...
