Hello, I'm HunMaster. I wanted to let you know that one of your recent contributions—specifically this edit to Polyvinyl chloride—has been undone because it appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Please take a look at the welcome page to learn more about Wikipedia. If you have any questions, you can ask for assistance at the Help desk. Thank you. HunMaster (talk) 13:33, 28 October 2021 (UTC)
