The correct quantity of desiccant to be used can be calculated by applying the DIN 55473 standard.
Package content: 100 pieces.
Product features
Tyvek® is a non-woven fabric composed of Polythene fibers, permeable to moisture and totally resistant to micro-dust.
These features make it particularly suitable for use in the pharmaceutical, electronic and optical fields.
Activated clay is a natural desiccant used to protect industrial packaging. In order to be used as a desiccant, it has to meet DIN 55473 standards.
Due to its adsorption properties and to its cost-effectiveness, clay is a good alternative to silica gel.
Absorption capacity of clay is defined as desiccant unit, which stands for the amount of clay needed to absorb a certain amount of water vapor (6 gr for 1 DIN desiccant units and 100 gr for 1 NFH desiccant unit) at 20°C and 40% RH.
This is the reason why the weight of desiccants containing clay is not steady, but it can change according to the clay absorption power (it has to be 18 +/- 1% of its volume according to DIN standards).
