Moisture adsorbing polymers

Moisture adsorbing polymers

Moisture Adsorbing Polymers provide an alternative to conventional desiccant bags and panel mounted desiccators. Brownell offers the polymers in two formats: Moisture Adsorbing Board (MAB) and Versatile Moisture Adsorbing Polymer (VMAP).

Moisture Adsorbing Board (MAB) is ideal for applications where space is limited. The board can be cut, punched or formed to produce specific shapes and sizes.

Versatile Moisture Adsorbing Polymer (VMAP) is a polymer based adsorbent material which has been developed by Brownell. VMAP can be moulded and machined to suit applications where complex shapes are required to occupy the available space. Molded components are used in a variety of applications, including drug delivery devices, point-of-care devices, sensors, and various electronics.

The polymer material is very easy to mold and machine which allows low cost, and rapid prototyping. They offer high adsorption capacity (9-12% by weight at 50% RH at 22°C) and can be reactivated.

Applications include electronics, airborne sensors, semiconductors, medical devices, photovoltaics, circuit boards, packaging, optics, computers, sensors, storage and shipping. The polymers are easily fixed by mechanical retention or adhesive.
