Sweden-based chemical company Perstorp has launched two new grades of carboxylic acids made of 100% renewable, mass balanced-attributed content. The new polyolester building blocks, Valeric Acid Pro 100 and 2-Ethylhexanoic Acid Pro 100, have ISSC Plus certification and can help companies reduce their products’ down-the-line (scope 3) emissions.
Polyolesters are synthetic lubricants used in refrigeration compressors of heat pumps, fridges, and other refrigeration technologies. They are compatible with refrigerants R134a, R410a, and R12, which have very high global warming potentials (GWP) between 1,400 and 2,000. The new polyolesters, which have a lower carbon footprint than their fossil-based counterparts, can therefore lower the carbon footprint of the refrigeration systems where they are used.
“The use of synthetic lubricants is making a positive impact by reducing the energy used and extending the lifetime of parts,” “said Dr. Valentina Serra Holm, Perstorp’s vice president of engineered fluids. “Now, in addition to sustainable applications, we can proudly offer a wide range of more sustainable building blocks for polyolesters.”
The launch follows Perstorp’s announcement in June 2022 that it would convert a major portion of the polyols produced at its production site in Perstorp, Sweden, to renewable products based on a traceable mass-balance concept.
