The Priplast range of polyester polyols are highly renewable, bio-based materials that reportedly allow formulators to create environmentally friendly, high-performance polyurethanes with improved performance. Priplast 3238 and Priplast 3286 are two new, 100% bio-based products that can offer increased renewability for green polyurethanes.
In laboratory testing, both products reportedly offered excellent durability and moisture repellency. In durability testing, they were able to maintain over 90% of their tensile strength, outperforming PTMEG and HDO-adipate. In addition, the products were shown to exhibit lower uptake of water in moisture repellency testing, compared to four other competitive polyols.
