1234ze SNAP applications



Dear Margaret,

When we talked on the phone the other day, you mentioned that you’re
putting together a compendium of approved substitutes for R-22 and 142b
that will be published in the Federal Register.  You asked whether
Honeywell is considering any other foam blowing uses for HFO-1234ze that
we have not applied for yet.  I consulted the business and this is the
response I got:

 

Absolutely!! Ultimately I’d like to see it approved for all foam uses,
but here’s my list of priority

 

Integral Skin Foam – should not have significantly higher emission
profile than already approved applications.

Polyolefin foam – should have same emission profile as XPS, which was
approved.

Rigid polyurethane and polyisocyanurate laminated Boardstock – should
have similar emission profile to other polyurethane foams already
approved

Rigid polyurethane slabstock and other– should have similar emission
profile to other polyurethane foams already approved

PS Sheet – This is likely to be 100% emissive at point of manufacture,
so we may need to do some calculations.  It is unlikely that we would
get any actual plant trial data any time soon.

Flexible foam - This is likely to be 100% emissive at point of
manufacture, so we may need to do some calculations.  It is unlikely
that we would get any actual plant trial data any time soon.

Phenolic Insulation Board– should have similar emission profile to
other polyurethane foams already approved

 

Could you please let me know how we should proceed to get these uses
added to our list?

Thank you,

Kasia
