TAFMER DF-840 (CAS NO : 25087-34-7)

Ethylene-Butene copolymer serves as a high-performance impact modifier in the polyolefins industry, where we operate as a leading bulk chemical supplier providing 98% purity grades for the plastics industry to enhance low-temperature toughness and heat sealability. This specialty Alpha-olefin copolymer is increasingly integrated into the high purity fine chemicals segment due to global sourcing shifts toward more resilient elastomers that meet stringent automotive and packaging standards. As globally established TAFMER DF-840 supplier, we ensure dependable supply, consistent quality, and complete regulatory documentation, including tafmer CoA and TDS across all grades. Beyond supply, we support partners through the entire product lifecycle from route scouting, process and formulation development, and analytical method development to scale-up, process optimisation, and pilot-to-commercial manufacturing. Our teams also assist with quality assurance, regulatory documentation, and global supply chain and logistics coordination.
