Purus International PS 3636 38 B EnviroTack Adhesive Mat, 36x36, 30-Layer, Blue, Case of 4
The Purus EnviroTack PS 3636 38 B is a 36" x 36" blue cleanroom sticky mat with 30 peel-away adhesive layers designed to capture and contain dirt, dust, and particulate from foot traffic and wheeled equipment at controlled environment entryways. The square 36x36 footprint is well-suited for wide single-door entries, equipment staging areas, and gowning room access points where equal width and length coverage is needed. Each layer is made from low-density polyethylene film with a full acrylic adhesive coating, and a numbered tab system allows single-layer removal. Made with Purus's plant-based Cardia BioHybrid material and recyclable in conventional plastic streams.
Sold in cases of 4 mats.

Frequently Asked Questions
When is a 36x36 square mat the right choice?
The 36" x 36" square footprint works well for wide single-door entries where equal width and depth coverage is needed, equipment staging areas, and corners or alcoves where a rectangular mat would overhang. It’s also a common choice for facilities that use mat frames designed for square configurations. If your entryway is wider than 36 inches, consider the 36" x 45" size for additional length coverage.
Is this a regular-tack or high-tack mat?
The PS 3636 38 B is a regular-tack mat with a peel adhesion of 6.5 oz / 190 g/25mm, suitable for most standard cleanroom and controlled environment applications with normal foot traffic. For heavy wheeled equipment or high-traffic ISO 5–7 environments, a high-tack version provides stronger adhesion.
How do I know when to peel a layer?
Peel when the top layer is visibly soiled, or on a scheduled interval per your contamination control SOP. The numbered tab on the mat edge shows how many of the 30 layers remain so you can plan reorders before running out.
What makes Purus EnviroTack mats more sustainable than standard sticky mats?
Purus mats incorporate Cardia BioHybrid material — a GMO-free, renewable, plant-based additive that reduces CO₂ emissions compared to conventional LDPE mats. They are also recyclable in standard plastic recycling streams, unlike most sticky mats which go to landfill after use.
