HFC Blowing Agents are under pressure to be phased out

Customer concerns that HFC (365/227) supply will drive conversion ahead of targeted dates

Finalized Rule 21

Unacceptable blowing agents: HFC-134a, HFC-143a, HFC-245fa, HFC-365mfc, HFC 227/365 blends; & Methylene chloride (I-skin and Flexible)

SNAP approved acceptable alternatives: HFC-152a, hydrocarbons, carbon dioxide, water, methylal, methyl formate, HFO-1234ze(E), HFO 1336mzz(Z), Solstice LBA: 1233zd(E).

Introducing Polycat® 218 non-emissive Catalyst, a new blow-biased catalyst that is fully compatible with Polycat 204, and can be used with both HFO-1233zd(E) and HFO-1336mzz blowing agents. Our patented Polycat 218 can impart faster initiation, additional blow catalysis, and excellent resin side stability.

Introducing Polycat® 203, a newly developed non-emissive catalyst specially designed for water sensitive and integral skin applications. Polycat 203 helps formulators to extend stability and reduce amine emissions when used with low GWP blowing agents.

Introducing Dabco® PM301 Blowing Agent Enhancer, a new, non-emissive, organic modifier that can promote HFO blowing agent solubility in SPF applications
