Recently, three association standards primarily formulated by MAYSTA, including Organosilicon Surfactants for Polyurethane Flexible Foams for Home Use, Organosilicon Surfactants for High Resilience Polyurethane Foams for Automotive Use, and Organosilicon Surfactants for Polyurethane Rigid Foams for Refrigerator Use, were approved and published after expert review by the China Polyurethane Industry Association (CPUIA), effective March 28, 2023.  

The polyurethane association standard "Household Polyurethane Flexible Foam Organosilicon Surfactants" applies to the silicon-carbon household prepared by hydrogen-containing polysiloxane and allyl polyoxyethylene-polyoxypropylene ether through the silica-hydrogen addition reaction, stipulates the technical requirements for household polyurethane flexible foam organosilicon surfactants, test methods, inspection rules, and marking, packaging, transportation and storage.

The polyurethane association standard "Polyurethane High Resilience Foam Organosilicon Surfactants for Automobiles" applies to polyurethane high resilience foam organosilicon surfactants containing organic siloxane polymers, and specifies technical requirements, test methods, inspection rules, and marking, packaging, transportation and storage of polyurethane high resilience foam organosilicon surfactants for automobiles.

The polyurethane association Standard "Polyurethane Rigid Foam Organosilicon Surfactants for Refrigerators" applies to silicone-carbon type polyurethane rigid foam organosilicon surfactants for refrigerators prepared by the reaction of silicone-hydrogen addition of hydrogen-containing polysiloxanes and allyl polyoxymethylene-polyoxymethylene ethers, stipulates the technical requirements, test methods, inspection rules, and marking, packaging, transportation and storage of the organosilicon surfactants for polyurethane rigid foams for refrigerators.
