ELASTOSPRAY BMB Isocyanate

Renewable feedstocks. Trusted performance. Verified transparency.

ELASTOSPRAY^® BMB Isocyanate is BASF’s biomass balance A-component for use across BASF spray polyurethane foam (SPF) systems. It is designed to deliver the same processing, performance, and code compliance as BASF’s conventional isocyanate while supporting a lower product carbon footprint at the spray foam system level, leveraging renewable raw materials at the start of the production process.

This specialty isocyanate is available for as a drop-in replacement of the A-component backbone for BASF spray foam systems including WALLTITE^®, ENERTITE^®, and SKYTITE^® formulations. It is a key part of BASF’s Future-Oriented Advanced Materials (F.O.A.M.) portfolio, helping support lower-carbon material options for the built environment without changing field application practices.

Biomass Balance Approach and Sustainability Overview

ELASTOSPRAY^® BMB Isocyanate is part of BASF’s broader effort to expand material solutions that help support evolving sustainability goals in construction, lowering embodied carbon in spray foam materials. Its sustainability profile is built on third-party certification, recognized life cycle assessment methodology, and system-level transparency.

• Renewable feedstocks through biomass balance

A portion of fossil-based raw materials is replaced with renewable alternatives at the beginning of the production process. These renewable inputs include feedstocks such as renewable natural gas generated from post-consumer waste. The renewable share is then attributed to ELASTOSPRAY^® BMB Isocyanate using a certified mass balance approach.

• Third-party certified chain of custody⁽²⁾

Renewable feedstock sourcing and attribution are verified under the REDcert² certification scheme, supporting credibility for the biomass balance model used in the chemical industry.

• Independently reviewed methodology

BASF’s biomass balance product carbon footprint methodology has been confirmed by TÜV Rheinland. This confirmation verifies that product carbon footprint reductions associated with biomass-balanced feedstocks are calculated in line with ISO 14067 and the Together for Sustainability (TfS) Product Carbon Footprint Guideline.

• EPD-backed system transparency

BASF spray foam systems containing ELASTOSPRAY^® BMB Isocyanate, including WALLTITE^® RSB and the ENERTITE^® Series, are supported by product-specific, cradle-to-grave Environmental Product Declarations (EPDs). These EPDs are independently verified by NSF International in accordance with ISO 14040/44, ISO 14025, and ISO 21930.

• Lower product carbon footprint at the system level⁽³⁾

When used in BASF spray foam systems, ELASTOSPRAY^® BMB Isocyanate can support meaningful reductions in product carbon footprint compared with conventional fossil-based BASF SPF systems. Depending on the system, carbon emissions reductions of up to 50% may be achieved versus BASF conventional spray foam systems.

Certifications and manufacturing commitment

REDcert² certification

Renewable feedstocks and their attribution to biomass balance products are certified under the REDcert² scheme, supporting traceability through the approved production chain.

TÜV Rheinland confirmation

BASF’s biomass balance product carbon footprint methodology has been reviewed by TÜV Rheinland, confirming alignment with ISO 14067:2018 and the TfS Product Carbon Footprint Guideline.

ISO-based site management systems

BASF production sites, including key isocyanate and polyurethane manufacturing locations, operate under ISO-certified quality and environmental management systems such as:

• ISO 9001:2015
• ISO 14001:2015

North American production commitment

BASF is investing in North American isocyanate capacity to support domestic production of biomass balance isocyanates, improve supply reliability, and help reduce lead times for the regional market.

^{[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] REDcert2 is a sustainability certification scheme for the use of sustainable biomass as raw material in the chemical industry. A certification according to this 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. Product-specific documentation, certifications, and code reports apply to the full BASF spray foam system, not the isocyanate component alone.}

^{(3) Carbon footprint reduction statements refer to BASF spray polyurethane foam systems formulated with ELASTOSPRAY® BMB Isocyanate compared with BASF conventional fossil-based spray foam systems, based on applicable life cycle assessment methodology and supporting documentation. Sustainability benefits are attributed through BASF’s certified biomass balance approach. The PCF 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.  PCF values reflect the situation at the time for the WALLTITE, ENERTITE and SKYTITE products being assessed - such data has been collected and is based on certain assumptions, approximations, and limitations.}
