Insulation industry news from Global Insulation

China/US: France-based Arkema has announced progress at two locations towards increasing the production capacity of its blowing agent product Forane 1233ZD. In China the group says its partner Aofan has started operation at a production plant. In the US at Calvert City, Kentucky the group has broken ground on the construction of an upgrade to a production line at its existing plant. The US$60m project is expected to be completed by early 2024. Both units are intended to increase the global availability of the Forane 1233ZD product.

The chemicals company is promoting the use of fluorinated liquid blowing agent due to its sustainability advantages. The product is used primarily in closed celled polyurethane foam for building insulation and cold chain applications. It also has applications for the thermal management of batteries in electric vehicles.

US: Honeywell has filed legal action against MEK Chemical for selling HFC-245fa in the US, an alleged violation of a Honeywell process patent. The liquid blowing agent used in the production of foam insulation, is manufactured by Honeywell under the brand name Enovate, according to ICIS.

Saudi Arabia: Honeywell and Bayer Pearl are targeting the Saudi Arabian market with a spray foam system that uses a proprietary Honeywell liquid blowing agent.

“We are delighted that Bayer Pearl has formulated their new spray foam system with Solstice Liquid Blowing Agent and are encouraged that Saudi Arabian leaders are considering implementing these new technologies to further enhance their economy and society,” said Amir Naqvi, regional marketing leader at Honeywell Fluorine Products.

The announcement follows a workshop in Riyadh entitled ‘Sustainable Solutions for polyurethane Foam’ that has looked at organic insulation. In the wake of the Saudi 2030 Vision development plan it is anticipated that 1.5m new homes will be required in the country and energy demands will also grow. Demand for thermal insulation is expected to rise in line with this.

France: Multinational chemical producer Arkema has patented the use of Forane(R) 1233zd as a blowing agent in the manufacture of polyurethane foams. The new molecule, known in its development phase as AFA-L1, is high purity trans-1-chloro-3,3,3-trifluoropropene, a liquid halogenated olefin. It offers improvements in energy performance and environmental benefits over existing blowing agents.

"In all of these evaluations, in several different polyurethane foam applications, Forane(R) 1233zd blowing agent has consistently demonstrated outstanding ease of use," noted Nancy Storoz, Global Business Manager for Arkema fluorochemicals foams and 134a refrigerants, "It requires minimal equipment modifications and formulation changes, while outperforming HCFCs, HFCs and hydrocarbons in terms of energy efficiency, R value, and vapor pressure."

In trials at a manufacturer of household refrigerators and freezers, an unoptimised system based on Forane(R) 1233zd blowing agent delivered a 3% improvement in energy efficiency versus HFC 245fa and surpassed 2014 DOE energy standards. In other evaluations conducted by Arkema, Forane(R) 1233zd blowing agent provided a 6% improvement in insulation value versus HFC 245fa, a 7% improvement versus HCFC 141b, and a 16% improvement versus hydrocarbons.

Target markets for Forane(R) 1233zd blowing agent include polyurethane foams used in the manufacture of household refrigerators and freezers, commercial refrigeration, spray foam, and polyurethane panels for commercial and residential building and construction applications.
