BASF launches ELASTOSPRAY BMB isocyanate to expand low‑carbon solutions in North American spray polyurethane foam market

• A biomass balance (BMB) product that offers a drop-in solution with no reformulation or process changes required
• Potential for product carbon footprint reductions between 21% and 29% compared to the BASF conventional spray polyurethane foam systems

WYANDOTTE, MI, April 24, 2026 – BASF has introduced ELASTOSPRAY^® BMB, a biomass balance^[1] isocyanate developed for use with BASF spray polyurethane foam (SPF) systems, delivering reduced embodied carbon while maintaining the same trusted performance, processing, and compliance as conventional BASF isocyanates.

ELASTOSPRAY BMB isocyanate expands BASF’s portfolio of low carbon building materials^[2] and supports growing demand from builders, contractors, architects, and specifiers for solutions that combine high performance with credible, third-party verified sustainability attributes.

“ELASTOSPRAY BMB isocyanate enables our customers to leverage a reduced product carbon footprint in our SPF insulation systems without changing formulations, processing conditions, or application practices,” said Nancy Houle, BASF Business Director for Spray Polyurethanes North America. “This drop-in solution helps advance construction sustainability goals while preserving the reliability and performance the industry expects from BASF.”

ELASTOSPRAY BMB isocyanate uses a certified biomass balance approach in which renewable feedstocks, such as renewable natural gas derived from landfill waste, are integrated at the start of the production process and attributed to specific products through a certified mass balance method.

The product is independently verified under the REDcert² certification scheme^[3], ensuring transparency and credibility of the renewable feedstocks. BASF’s biomass balance methodology is also independently certified, supporting product carbon footprint calculations^[4] in accordance with internationally recognized life cycle assessment standards.

Designed for more sustainable construction

When used in BASF spray foam systems, including WALLTITE^® RSB and ENERTITE^® Series formulations, ELASTOSPRAY BMB Isocyanate supports systems with product-specific Environmental Product Declarations (EPDs), providing transparent, third-party verified environmental data for use in building life cycle assessments and green building programs.

Manufactured using renewable energy inputs, and produced for the North American market, ELASTOSPRAY BMB isocyanate reinforces BASF’s commitment to local supply reliability while helping customers meet evolving sustainability expectations across residential and commercial construction.

[1] Biomass balance method (BMB): Fossil raw materials required for the manufacture of BASF products are replaced with renewable feedstock along the integrated production chain. The corresponding share of renewable material is attributed to the specific sales product via a certified mass balance approach. Production methods of this kind save fossil resources and reduce CO2 emissions at the same time. Renewable feedstock is not traceable in the BASF product. 

[2] Product carbon footprints reflect the situation at the time for the WALLTITE, ENERTITE and SKYTITE products - such data has been collected and is based on certain assumptions, approximations and limitations.

[3] REDcert2 is a sustainability certification scheme for the use of sustainable biomass as raw material in the chemical industry. A certification according to these certification schemes confirms that the biomass used is sustainable and has been fed into the production system in the required amount. It also confirms that the sustainable biomass has been correctly attributed to the corresponding sales products. The certifications are awarded on the basis of on-site audits conducted by independent auditors.

[4] The product carbon footprint calculations follow the requirements and guidance given by ISO 14067:2018.  Additionally, the calculations are aligned with the GHG Protocol Product Standard (WRI & WBCSD, 2011) and the Together for Sustainability PCF Guideline.
