Singapore - Machinery group RIM Polymers Industries Pte Ltd has launched a new pre-mix unit, Model PX40-3C & PX50-3C, for three components -- namely polyol and blowing agents HFC-245fa (hydrofluorocarbon-245fa) and pentane.
The Singapore-based machinery maker, which supplies a lot of equipment into the Chinese market, said the new model is a follow up of its successful PX 40fa version, for blending HFC-245fa blowing agent and polyol. The new model is aimed particularly at the appliance industry in the Asian market, where demand for the three-component type has increased remarkably, said RIM Polymers, in a 29 Jan announcement.
The 3-C version provides versatility, with the option to select either 245fa or pentane as only blowing agent, or to combine both blowing agents.
The shift towards using combined agents has aroused great interest among appliance industry, firstly, because using 245fa alone remains costly and combining with pentane helps reduce blowing agent costs, the company explained.
Secondly, refrigerator makers can use a grade of ABS (the thermoplastic acrylonitrile butadiene) sheet material for the fridge body similar to that used with 245fa alone as blowing agent, the company points out. Normally a grade of ABS sheet with better anti-static characteristic has to be used when working with pentane alone, said RIM Polymers.
Combined blowing agents continue to yield better energy saving for consumers -- because the thermal coefficient will not be compromised, according to the machinery maker.
