<b>Polyurethane rigid foam industry, it is imperative to accelerate the elimination of 141b</b>

“Recommended List of Substitutes for Ozone Depleting Substances in China” was issued to accelerate the phase-out HCFCslike substances

2023year6month12On the 12th, the Ministry of Ecology and Environment and the Ministry of Industry and Information Technology of China jointly issued the “Recommended List of Substitutes for Ozone Depleting Substances in China” . According to the person in charge of the Department of Atmospheric Environment of the Ministry of Ecology and Environment, at present, China is developing the last category of ozone-depleting substances(ODS)HCFC(HCFCs)The elimination and replacement work, and has been realized2013year freeze,2015year reduction10%and2020year reduction35%The goal is now to2025Annual cut67.5%The goal is accelerated.

According to the “Recommended List” issued this time, in the application field of polyurethane foam, carbon dioxide, cyclopentane, n-pentane, isopentane, whole water, organic alcohol amine salt of carbonic acid are recommended, AlternativeHCFCsseries of ozone-depleting substancesHCFC-141bHCFC-141b、HCFC-22、HCFC-142b.

ChinaPUhard foam industry, accelerate the phase-outHCFC-141bfoaming agent is imperative.

ChinaPUThe hard foam industry is actively implementing HCFC-141bissued Foaming Agent Phase-Out Management Plan

The first phase of elimination:

Since 2011, China’s polyurethane industry has begun to implement the “Polyurethane (PU) The first stage of the bubble industryHCFCsElimination Management Plan”, actively carry out span>HCFCslike substances ( span>HCFC-141b) in the industry Elimination and phase-out plan within. Prioritize selection of hard foam enterprises with strong technology, capital and management capabilities, large scale and high demonstration for elimination, and sign a total of 57item HCFC-141bThe phase-out contract involves refrigerator freezers, refrigerated containers, electric water heaters, pipe insulation, panels, solar water heaters, etc. Industry, mainly adopts alkane (cyclopentane) and water foaming technology, totally eliminated12969tHCFC-141b, at the same time, with 8A combined polyether manufacturer has launched a cyclopentane or water premixed polyether capacity building project, through funding its production of premixed cyclopentane or water combinations The ability to polyether to increase the market supply of pre-blended cyclopentane or water-combined polyethers.

Refrigerator freezer is currently the largest downstream industry of hard foam in China (in terms of hard foam consumption). 2018year, refrigerator The industry of refrigerators, water heaters, and refrigerated containers has basically realized the implementation of 141b.

The second elimination stage:

2017year, ChinaPUThe second stage of the foam industry containing hydrochlorofluorocarbons (HCFC) the phase-out work has officially started. In the second stage of early elimination activities, it has been realized as scheduled2018year reduction30% phased goals, and in 2019year and11Project company signedHCFC-141bPhase out the contract, add hydrochlorofluorocarbons on the basis of the alternative technology adopted in the first phaseHFOLike green and low-carbon alternative technology options, involving panels, pipe insulation, solar water heaters and automatic Crust sub-sector.

2022year12monthOn December 12, the Ministry of Ecology and Environment issued the “About Prohibition of Production and 1,1-dichloro-1-fluoroethane (HCFC-141b) is the foaming agent insulation tube Products, Solar Water Heater Products Announcement (Draft for Comments)” is open for comments. The announcement proposes that from 2023year7monthFrom 1st, no company shall use HCFC-141bProduce insulation pipe products and solar water heater products for foaming agent.
