Device for drying laundry by means of a current of air comprises a drum to accommodate the laundry and a ducting system to direct said current of air. The device is of a simple, compact construction that includes a first adapter that can be easily connected to a container containing the powder component and a second adapter that can be removably interconnected with the first adapter and can also be readily connected to a container containing a fluid such as a diluent so as to permit aseptic intermixing of the diluent with the powder. This allows a defective or failed SRAM macro to be shut off and replaced by a spare macro, dramatically increasing manufacturing yield and decreasing field replacement rates. The composition may also contain an antistatic ionomer, in an amount that is less than 15% by weight, based on weight of the thermoplastic elastomer.
