Anti Vibration Pad sheet 18" x 18" x 3/4" All Rubber Vibration isolation sheet

Believe the other reviewers and not the vendor - the odor is overpowering and doesn't go away any time soon. Even a section I had outside in the weather for months still smells. Odds are this is made in China and the odor isn't 'rubber' smell, but more likely a petroleum-based cheapening filler additive, which by the way are often hazardous / carcinogenic and often used in Chinese rubber products. I work around a lot very large (500-1000#) new rubber objects and they barely smell at all, and all the rubber engineers say this odor isn't normal unless the nasty fillers are used.
