As you are most likely aware, HFC-134a is the non-flammable aerosol propellant that manufacturers use in producing dusters and other non flammable aerosol products used by the electronics industry. Demand for this material continues to climb while supply has not increased at all in recent years. This has caused a situation where the cost of this material is now increasing steadily, hence the increase in pricing for our Super Duster 134 (Cat. No. 402A).

Alternative to 134a Duster

To ensure that MG Chemicals can continue to offer a price competitive duster product,
we are now introducing Super Duster 152 (part # 402B-340G), which uses HFC-152a
as a propellant. At one time, HFC-152a and HFC-134a were about the same cost,
but recently the price of HFC-152a has held steady while the price of HFC-134a
has increased, making HFC-152a an attractive alternative. Another benefit of
HFC-152a is that its global warming potential is 1/10th of that of HFC-134a.

Comparison of duster products

HFC 152a is rated as non-flammable when subjected to the 'Test for determining the the flashback and the length of the flame projection of flammable product enclosed in a spray container' of the Canadian Hazardous Products Act. This product is not defined as flammable by 1500.3 (c)(6),16 CFR, Fed. Haz. Substance Act, C.P.S.C. Regs.
