Polycarbonatdiole (Ravecarb) EN: Polycarbonate Diols (Ravecarb) are advanced polyurethane building blocks designed for applications requiring exceptional durability, hydrolysis resistance, mechanical strength, and long-term performance. Their unique carbonate-based structure provides significant advantages over conventional polyols, making them highly suitable for premium polyurethane coatings, elastomers, synthetic leather, adhesives, sealants, and specialty materials. 

Polyether Polyols – Petol® Polyether Polyols "Petol", are polyhydroxyl-containing polymeric compounds primarily used as key raw materials for the production of polyurethane (PU) materials. They are produced by the alkoxylation of starter molecules such as glycols, glycerol, amines, and multifunctional compounds with ethylene oxide and/or propylene oxide. Due to their adjustable chemical structure, molecular weight, functionality, and reactivity, polyether polyols are essential components in flexible foams, rigid foams, elastomers, coatings, adhesives, and sealants. We could provide wide range of different Diols, Triols, Polymer and San and Mannich Polyols with various molecular weights. CAS numbers divers: | 25322-69-4 | 25791-96-2 | 53637-35-5 | 9082-00-2 | 25214-63-5 | 701-426-6 | 68909-26-6 | Polymer | 

EN: Polytetrahydrofuran (PTMG) is a premium polyether diol and one of the most important building blocks for high-performance polyurethane materials. Its exceptional elasticity, low-temperature flexibility, abrasion resistance, and durability make it essential for TPU, spandex fibers, elastomers, coatings, adhesives, and specialty polymer applications. Due to the growing demand for lightweight, flexible, and durable materials, PTMG continues to be a key raw material in advanced polyurethane technologies. Beside PTMG 1000 + 2000, we also could provide special grade such PTMG 250 + 650.
