PurMat® sticky mats can be used in all access areas to cleanroom up to ISO 6 and effectively avoid the transfer of dirt from unclean areas into the cleaner areas. Dust and particles are removed reliably from passing surfaces by the adhesive layers of the mats, during the entry of personnel and equipment into cleanroom areas. These 30-layer floor mats are made of high strength PE materials, coated with water-based acrylic adhesive.
