Phase out of R141b is major step in South Africa’s HPMP

Where are we with banning the importation of the HCFC blowing agent R141b in terms of South Africa’s phase-down schedule for ozone depleting substances?

As a signatory of the Montreal Protocol, South Africa phased out the importation and production of CFCs on 1 January 1996. Because of the high ozone depletion potential (ODP) of CFCs like R11, R12, and R502, the international community first focused on the phasing out of these man-made substances to halt the damage to the ozone layer at between 10 and 30km above the earth’s surface.

Next-Generation Appliance Foams: The Challenges Ahead

One of our Chemists, Raul Dacomba, wrote a white paper for Appliance Design.

Change is a certainty in this world, and the appliance industry is no exception. Regulatory mandates are imposing yet another transition to a new generation of polyurethane foam blowing agents. The legislation states that Hydrofluorocarbons (HFCs) and blends will be unacceptable for use starting January 2020. Refrigerant use will be unacceptable starting January 2021.

A blowing agent is one of many key ingredients used to manufacture polyurethane foams; their inherently low thermal conductivities are a desired trait. Before delving into specifics on the future of appliance foams, it is important to understand the history of blowing agents.
