Polyol producer Nanjing Hongbaoli claims to make inroads into the market for fire-retardant (FR) insulation foams by offering new highly FR polyisocyanurate (PIR) systems based on its aromatic polyester polyols (APPs), said Horace Xing, technical manager.
“By May we will expand our capacity to 160 ktpa from 100 ktpa,” investing about RMB 250 million ($39 million) in this project – the cash raised from its recent listing on the domestic stock market. Most of the funding will be used for these FR materials, for construction, he emphasised.
This is because China is developing stringent rules on fire behaviour of construction materials Hongbaoli is able to offer panel manufacturers polyester polyols and systems with a very high level of fire resistance, Xing said.
In its other major outlet, the appliance sector, Xing claimed Hongbaoli has 11 patents on a pressure-reducing foaming technology (see p 24 for news of a breakthrough in this area by Dow Polyurethanes/Cannon Group).
Hongbaoli sells to appliance groups such as BSH Horne Appliances Ltd (Bosch Siemens), Haier, Arelik (ofTurkey), and LG Group in Korea.
“All the top companies in the world are coming to talk to us about their interest in cooperating in this area,” Xing claimed.
Using this technology would raise energy efficiency by 6 percent and reduce material…
