I’ve been researching this all morning and keep running into articles that explain why YKK is a great company and what is unique about their zippers, but no article that explains the technical design of the product.
Would love an explanation that goes beyond the very simple “YKK zippers actually lubricate themselves as you zip and unzip them.”
Thank you!

According to the available documentation, their self-lubricating zippers are made of a polymer (essentially a plastic) mixed with what they refer to as a “slip additive”, which appears to be a waterproof lubricating agent. The polymer is porous and so allows the lubricant to come out upon the zipper being used.
