Our 1H1, and 1H2 plastic drums are made from high-density polyethylene (HDPE). These are all suitable for use as single-packaging and come in a range of different sizes. What makes HDPE suitable is the resistance to both high and low PH levels. This makes it a great choice for a lot of different dangerous goods. It is the shipper's responsibility to check the suitability/compatibility of the UN packaging material for the dangerous goods in question. For example, some contents such as specific solvents are not suitable for use in HDPE plastic drums. In this case, a UN steel drum may be a suitable choice for your products.
