CAS 109-66-0 Pentanes are particularly suitable as physical blowing agents for the production of insulating materials, such as PU, PIR, EPS or XPS foams.
Pentanes are key in this context. As blowing agents in insulating foams, they are largely responsible for the excellent performance of the insulating materials. All three isomers of Pentane are used: n-Pentanes, iso-Pentanes and Cyclopentanes. It is particularly important for manufacturers of insulating materials to have high quality, individual blend compositions and tailor-made formulations.
Those responsible for purchasing in the insulation and refrigeration industry therefore look for high-quality Pentanes with the following quality characteristics:
- High purities of 95 % and more
- Free from disturbing impurities such as aromatics, sulphur and odour
- Possibility of customised Pentane blends
- No ozone depletion potential and low GWP (Global Warming Potential).
Why Use Pentane as a Blowing Agent in Foam Production?
It Puffs Up Foam: When heated, pentane turns into a gas, creating the bubbles (cells) that make foam light and expanded.
Excellent Insulator: The gas trapped inside the foam cells has very low thermal conductivity, making the insulation highly effective.
Environmentally Friendly: It has Zero Ozone-Depleting Potential (ODP) and a very low Global Warming Potential (GWP), unlike older banned chemicals (CFCs).
Cost-Effective: It's relatively cheap and readily available from petroleum refining.
Works Well: It's highly volatile (evaporates easily) and mixes well with the polymers (like polystyrene or polyurethane) used to make foam.
