Permeation

Permeation Resistance Testing of Rubber & Plastics

It is now common practice to have rubber and plastic materials, gloves, chemical protective clothing (CPC) and medical devices analyzed for permeability against numerous laboratory reagents, general chemicals, hazardous chemicals and hospital substances. ARDL understands the importance of, and can offer, expert advice regarding the selection and testing of the most appropriate materials for a particular application along with the corresponding shelf and service lives of such materials.

Membrane Permeability Testing of Protective Clothing & Coated Fabrics

Evaluation is also often required or recommended on most gloves and other articles of CPC as well as on some medical devices. ARDL helps both CPC/device manufacturers and CPC/device users evaluate and minimize product contamination to provide unsurpassed personal protection.

Chemical Resistance Testing of Rubber & Plastics

Your rubber and plastic materials, gloves, chemical protective clothing (CPC) and medical devices may need to be tested for safety in chemical rich environments. ARDL can perform in-depth analysis against a wide variety of chemical reagents used in hospital settings, military and aerospace applications and household chemicals.
