toyocat ets is a double (dimethylaminoethyl) ether also known as catalyst a1, catalyst a-1, bdmaee. 70% bis (dimethylaminoethyl) ether dipropylene glycol solution, strong foaming catalyst, the domestic industry usually called it catalyst a-1 or a1. a1 catalyst is mainly used for the production of soft polyether polyurethane foam, and can also be used for hard foam packaging. a1 catalyst has a particularly strong catalytic effect on water, so the foam density can be reduced. it is about 80% effective in controlling reactions that produce gases and about 20% effective in controlling gel reactions. the catalyst activity is high, the amount is small, adjust the amount of this series, can control the foam rise and gel time.
alias: double (dimethylaminoethyl) ether, english abbreviation bdmaee, belongs to the foaming catalyst, but also polyurethane foaming catalyst

product introduction
toyocat ets is a double (dimethylaminoethyl) ether also known as catalyst a1, catalyst a-1, bdmaee. 70% bis (dimethylaminoethyl) ether dipropylene glycol solution, strong foaming catalyst, the domestic industry usually called it catalyst a-1 or a1. a1 catalyst is mainly used for the production of soft polyether polyurethane foam, and can also be used for hard foam packaging. a1 catalyst has a particularly strong catalytic effect on water, so the foam density can be reduced. it is about 80% effective in controlling reactions that produce gases and about 20% effective in controlling gel reactions. the catalyst activity is high, the amount is small, adjust the amount of this series, can control the foam rise and gel time. a1 and organotin catalyst shared, can make the production tolerance of foam significantly improved, to ensure that in the production will not cause unnecessary quality problems due to careless operation or small errors in the measurement system, the production of high-quality soft foam. a1 catalyst is widely used in the manufacture of polyurethane foam in a variety of formulations, especially suitable for the production of high resilience, semi-hard foam and low density foam.

disclosure treatment
stop leaks as much as possible while ensuring safety. if a minor leak is found, treat it with sand or other absorbent material and place it in a clean, dry container for subsequent treatment. if a large amount of leakage occurs, the leaked material should be collected for subsequent treatment. avoid material entering groundwater or surface water, because it is not easily degraded by biological matter. all collected leakage materials should be disposed of in accordance with the relevant regulations of the local environmental protection department.
