ADI has recently reviewed propellants and the pack sizes offered in the Australian and New Zealand commercial markets. Due to low volume sales of 4kg packs of AR2205, AR2213SC and AR2217, it has been decided to offer these products in the 500 gram container only. Bench Mark 1, Bench Mark 2, AR2219 and AR2225 will also be available in the 500g pack only. However due to increase popularity of the propellant AR2206H, it will now be available in the 500g and the 4kg container sizes.
