The Partnership combines Selenis’ specialty polyester manufacturing capabilities with Kintra’s patented fiber-grade PBS (polybutylene succinate) technology.

Through Texnascis, its brand focused on innovation in sustainable and high-performance fibers, Selenis will serve as Kintra’s industrialization partner, leveraging its large-scale polymerization infrastructure, process engineering capabilities, and specialty polyester production expertise to bring the material to commercial volumes.

“At Selenis, we see strong potential in technologies that combine material innovation with commercial viability,” said Eduardo Santos, Strategy and Integration Director at Selenis. “Kintra has developed a differentiated fiber-grade PBS engineered for fiber production and premium textile performance. We are proud to bring this solution to scale through our manufacturing capabilities.”

The partnership gives the textile industry access to 100% bio-based and biodegradable fibers that deliver the performance, scalability, and processing compatibility apparel brands need to transition away from petroleum-based synthetics. With the textile industry producing over 90 million metric tons of petroleum-based synthetic fibers annually, scalable bio-based alternatives are critical to transforming raw material sourcing.

“Selecting the right industrial manufacturing partner to scale our technology was a top priority,” said Billy McCall, CEO and Co-Founder of Kintra Fibers. “Selenis brings the polymerization infrastructure, technical rigor, and production control needed to manufacture our resin at the quality and volume the market demands. This partnership creates a clear path to market.”
