Purus International PM 2436 34 W EnviroTack Adhesive Mat, 24x36, 30-Layer, White, Case of 4
Purus International PM 2436 34 W EnviroTack Adhesive Mat, 24x36, 30-Layer, White, Case of 4
The Purus EnviroTack PM 2436 34 W is a 24" x 36" white 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 24x36 footprint is one of the most widely used sizes in cleanroom and controlled environment applications, fitting standard single-door entries and gowning room access points. 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
What is the difference between the PM 2436 34 W and the PS 2436 38 W?
Both are 24" x 36" white regular-tack mats in a case of 4, but the PM 2436 34 W has a thicker film per layer (1.8 mil vs. 1.4 mil for the PS 2436 38 W). The thicker film provides a slightly more substantial feel underfoot and may be preferred in environments where mat durability per layer is a priority.
Why is 24x36 one of the most common cleanroom mat sizes?
The 24" x 36" footprint fits most standard single-door entries and provides enough surface area to ensure both feet contact the adhesive with each step. It’s also a practical size for gowning room benches and secondary contamination control checkpoints. For wider entries or double doors, the 36" x 45" size is recommended.
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. Most facilities follow a time-based or traffic-count schedule rather than relying solely on visual inspection.
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.
