The REvolution rosin ester technology enables the development of biobased products with light colour and oxidative stability, said the specialty chemical company Kraton in a statement announcing the news.
The scalable technology has been applied in the development two new sustainable Sylvalite products: Sylvalite 2100 and Sylvalite 9100 Rosin Ester Tackifier. Tackifiers are low molecular weight compounds used in formulating adhesives to increase the stickiness, or tack, of the surface of the adhesive. They serve to increase the adhesion of hot-melt systems on various substrates.
Kraton's REvolution rosin ester technology delivers biobased products with light colour and oxidative stability, providing formulators with a broader range of solutions in support of their sustainability goals.
"Kraton's latest innovations exemplify our commitment to deliver sustainable solutions for the industry," said Peter Migchels, Kraton's Marketing Director – Adhesives.
"Our REvolution rosin ester technology offers a major step change for manufacturers looking to achieve light, stable hot-melt formulations with high biobased content.”
Kraton is the world’s largest producer of pine chemicals and specialty resins based on crude tall oil (CTO) and crude sulphate turpentine (CST). As by-products of the Kraft pulp industry, CTO, CST and its primary bio-refinery products are used as a renewable feedstock base for high-quality product and sustainability performance. Derived from responsibly-managed forests, CTO has a substantially lower carbon footprint compared to other known vegetable or fossil-based alternatives.
Approximately half of its products are derived from renewable resources, and over 100 of those products are certified in the Biobased Content Certification Scheme, which validates a product’s biomass content based on the European standard EN 16785-1.
The company’s comprehensive commitment to sustainability, not only to the products it produces but throughout the organization, was recognized earlier this year with its first EcoVadis Gold rating.
Its points score and the resulting Gold rating put it in the top 98 percentile of its industry.
