POLYVEST® eCO - Liquid rubber solutions incorporating renewable and circular feedstock concepts.
POLYVEST® is supporting increased use of renewable and mass-balanced raw materials by offering products based on renewable and mass-balanced feedstock concepts under the brand name POLYVEST® eCO.
With our POLYVEST® eCO brand we provide liquid polybutadiene products compliant with the sustainability criteria laid down by the ISCC, a voluntarily certification and a trusted standard.
Our POLYVEST® eCO grades
- do not differ in their physicochemical properties versus standard grades derived from fossil-based raw materials
- can be used use as drop-in replacements by our customers because they do not require any additional tests, requalification, or investment
- bring same performance characteristics while supporting lower product carbon footprints, based on applicable lifecycle assessment methodologies.
ISCC Plus Sustainability Certification
POLYVEST® is certified by the ISCC organization to operate under the ISCC PLUS certification scheme based on mass balance approach. This certification ensures the exact and complete traceability of certified renewable and/or recycled feedstocks used in our production plants and confirms that the used raw materials originate from ISCC-certified renewable or recycled feedstock sources.
The ISCC PLUS certification covers our product portfolio produced with sustainable raw materials that are produced based of different feedstocks.
The use of certified renewable or recycled feedstocks may contribute to lower greenhouse-gas emissions and reduced demand for fossil feedstocks, depending on product-specific assessments.
Mass Balance Approach - How does that work for POLYVEST® eCO
With the development of our first product portfolio based on renewable and mass-balanced feedstock allocation - our new POLYVEST® eCO - we have taken an important step toward increasing the use of certified renewable and recycled feedstocks. With POLYVEST® we offer a range of stereospecific low viscous liquid polybutadienes of different chemical compositions. Based on the characteristic microstructure, all grades exhibit an excellent ractivity and could be used for abroad field of applications such as adhesives and sealants in the construction market, in the automotive industry or in tire and rubber compounds.
Sustainability & POLYVEST® liquid polybutadienes
We have a strong focus on sustainability – both regarding our products (Footprint) but also the applications they are used in (Handprint).
Footprint
The following POLYVEST® grades are available as POLYVEST® eCO:
- POLYVEST® eCO 110 Bio
- POLYVEST® eCO 130 Bio
- POLYVEST® eCO 130 S Bio
- POLYVEST® eCO MA 75 Bio
- POLYVEST® eCO HT Bio
- POLYVEST® eCO ST-E 60 Bio
- POLYVEST® eCO ST-E 60 BioCirc
For improving the footprint, we use raw materials from alternative sources and offer a drop-in solution with a lower carbon footprint.
Handprint
The handprint describes the specific environmental or resource-efficiency benefits in selected applications. See our two examples:
- POLYVEST® HT in window glazing in Sustainability Report 2022
- POLYVEST® ST-E for green tire formulations as featured in the Evonik Next Generation brochure (page 34).
