Low-density microsphere-enhanced biodegradable injection molding resins
Revolutionary biodegradable resins with embedded hollow microspheres reduce density and enhance strength. Ideal for packaging, these resins offer full compostability, recyclability, and compatibility with standard injection molding processes.
Overview
Saber Chemical, Inc. introduces a groundbreaking advancement in biodegradable injection molding resins. By integrating nanoscopic hollow microspheres into PLA, PHA, or PBS matrices, these resins achieve a density lower than 1 g/cm³ without sacrificing strength. This innovation provides a sustainable alternative to conventional materials, offering toughness comparable to ABS and melt flow indices aligned with polyethylene and polypropylene. The resins are fully compostable and maintain flotation for efficient recycling separation, addressing both mechanical performance and environmental sustainability.
Technical specifications
- Core technology: Hollow, rigid-shell microspheres created from glycerol ketal acrylates.
- Manufacturing process: Multistage emulsion polymerization to produce biobased, biodegradable particles.
- Material properties: Density <1 g/cm³, melt flow index (MFI) of 25–55, toughness benchmarks validated by ASTM testing.
- Compatibility: Designed for drop-in use in existing injection molding systems for closures and packaging.
- Environmental benefits: Fully compostable, FDA-clearable components, and compatibility with recycling processes.
Technology readiness level
Currently at Technology Readiness Level 2, Saber Chemical, Inc. plans to further validate and scale the technology. Phase I involves lab-scale development and ASTM testing. Phase II will expand production to larger scales, with third-party certification for compostability and food-contact compliance. Field trials will demonstrate practical applications, advancing towards commercial readiness.
About Saber Chemical, Inc.
Saber Chemical, Inc. specializes in the development and commercialization of compostable core-shell particles (CCSPs) designed to enhance the performance of bioplastics. By integrating these CCSPs into materials such as PLA, PHA, PBS, PBT, PBAT, TPS, and PCL, the company produces performance-grade pellets that offer increased toughness, often achieving greater than 200 J/m Izod impact strength, while maintaining ASTM D6400 compostability. This technology, which originated from NSF-funded research, utilizes glycerol-ketal acrylates to create nanoscale particles that improve material properties without sacrificing environmental sustainability. The company's innovations are designed to be compatible with standard industrial manufacturing processes, including twin-screw compounding, extrusion, and injection molding.
These solutions are targeted at converters and manufacturers in sectors such as packaging, consumer goods, agricultural films, and medical devices who require high-performance, sustainable material alternatives. By providing a scalable approach to material modification, Saber Chemical assists partners in developing durable, compostable products that meet demanding mechanical and thermal requirements. The company engages with customers through technical data support, sample requests, and collaborative research and development efforts, leveraging expertise in polymer chemistry and sustainable monomer synthesis to facilitate the adoption of its additives in commercial applications.
