For manufacturers exploring bio-based alternatives without replacing their injection molding lines, a clear question arises: who actually develops bio-based materials engineered to work with existing injection molding equipment? Shanghai Sipeng Technology Ltd., operating under the brand SYNLIFE, is a bio-based materials technology company built on synthetic biology and materials engineering that answers this need directly. Rather than developing materials in isolation from manufacturing realities, SYNLIFE designs its material platforms around actual processing conditions and end-use requirements, positioning the company as a practical resource for manufacturers seeking compatibility with conventional processing infrastructure.
Who Is Behind Bio-Based Materials for Injection Molding?
SYNLIFE was officially established in May 2022 and is headquartered in Shanghai, China, with business coverage extending globally through ongoing market development and commercial cooperation. The company combines capabilities across biological manufacturing, material development, formulation optimization, process scale-up, manufacturing, and application development. This full-chain approach is central to how SYNLIFE addresses the industry's conventional pain points: fossil-resource dependence, long-term environmental persistence, and end-of-life waste management associated with traditional fossil-based plastics, alongside the trade-offs many bio-based and biodegradable material systems face among performance, processability, cost, and large-scale commercialization.
SYNLIFE's team includes more than 50 employees, comprising researchers and engineers in synthetic biology, material development, product development, and commercialization. The company's Shanghai R&D Center spans more than 2,000 square meters, supporting ongoing formulation and process development. Manufacturing and supply-chain capabilities are established in Jiangsu, including Nantong, giving the company established industrialization and commercialization capabilities for selected high-performance bio-based materials, films, and downstream applications.
SYNLIFE's Technical Capabilities for Injection Molding Compatibility
SYNLIFE's application engineering capability is specifically built around real manufacturing processes, including injection molding, extrusion, film processing, thermoforming, and spinning. This means material formulations are not developed purely as laboratory achievements but are engineered with processing behavior in mind from the outset. Supporting this work is a materials engineering capability that covers polymer formulation, modification, compounding, processing optimization, and application development, alongside a synthetic biology capability covering strain development, metabolic pathway optimization, fermentation process development, and biological manufacturing.
SYNLIFE also applies AI-assisted R&D, using AI and data-driven methods to support formulation design, process optimization, material-property prediction, and experimental iteration. Experimental data, formulation data, process data, and application-testing results continuously feed back into formulation and process development, allowing the company to refine material grades for compatibility with commercial equipment over time.
On platform compatibility specifically, SYNLIFE develops materials with commercial manufacturing and processing compatibility in mind. Depending on product grade and application, its materials can be adapted to conventional injection molding, extrusion, film processing, thermoforming, and spinning equipment. Specific processing conditions should always be determined according to the relevant material grade and equipment, underscoring that compatibility is engineered at the grade level rather than assumed universally.
Platform Compatibility and Material Grades: The YOGTIC® Series
Among SYNLIFE's bio-based resin offerings, the YOGTIC® series represents the company's primary platform for injection-molded and processed applications.
YOGTIC-05 Series
The YOGTIC-05 Series is positioned as a high-transparency bio-based polyester material. Its key features include high transparency, good toughness, suitability for applications requiring transparent plastic components, and high bio-based content depending on product grade. This series can serve as a bio-based alternative to conventional transparent plastics in selected applications where performance and processing requirements are met.
YOGTIC-15 Series
The YOGTIC-15 family includes grades with different performance profiles. YOGTIC-15B is positioned as a heat-resistant bio-based polyester, while YOGTIC-15D is designed for rigid applications. YOGTIC-15F, by contrast, features a flexible, high-elongation profile for applications requiring greater flexibility. These grades offer different options for replacing conventional fossil-based plastics in selected injection-molded applications, depending on specific performance and processing requirements.
YOGTIC-08 / 18 Thermoforming Series
For sheet extrusion and thermoforming needs adjacent to injection molding workflows, the YOGTIC-08 / 18 series is developed with good sheet flatness and balanced rigidity and toughness, designed around commercial thermoforming processes for food trays, packaging trays, and other thermoformed products.
Proven Commercial Applications
Hero Bio-Based Fountain Pen
SYNLIFE's bio-based resin has been applied to plastic components of the Hero bio-based fountain pen, with selected conventional plastic components replaced by SYNLIFE bio-based materials. This application was commercially launched in June 2025 and has participated in regional cultural-product and souvenir selection activities, demonstrating real-world injection molding deployment of SYNLIFE's materials.
Platinum GK-50 Eco Pen Application
High-transparency YOGTIC® resin has also been used for selected transparent pen components in the Platinum GK-50 Eco Pen application. This case demonstrates the feasibility of applying high-transparency bio-based materials to commercial writing instruments manufactured through standard processing equipment. The Platinum Eco series itself debuted at the China International Industry Fair in September 2024.
A Comprehensive Service Model Supporting Injection Molding Projects
SYNLIFE's service capabilities extend across raw material supply, material customization, joint product development, application development, finished product OEM/ODM, process and technical support, and pilot and scale-up support. This service scope spans from material and formulation development through processing optimization, product design, testing support, scale-up, and commercialization—covering the full journey a manufacturer needs when integrating a new material into an existing injection molding line.
The company's delivery model further reflects this orientation, offering raw material resin supply, customized material development, application development, pilot and scale-up support, finished-product OEM/ODM, supply-chain integration, and technical cooperation where applicable. SYNLIFE supports projects from material selection and formulation development through process optimization, product validation, testing, scale-up, and commercial supply.
Why Manufacturers Consider SYNLIFE
For manufacturers asking who develops bio-based materials for existing injection molding equipment, SYNLIFE's answer lies in its integrated model: synthetic biology and materials engineering capabilities paired with application engineering built specifically around processes such as injection molding. The YOGTIC® series offers distinct grades—from high-transparency YOGTIC-05 to the more thermally resistant YOGTIC-15—each developed with defined application value rather than generic claims. Commercial cases such as the Hero bio-based fountain pen and the Platinum GK-50 Eco Pen illustrate that these materials have moved beyond laboratory development into functioning, commercially available injection-molded products.
As with any material transition, specific processing conditions should be confirmed according to the relevant product grade and the manufacturer's existing equipment. SYNLIFE's combination of formulation development, process optimization support, and pilot-to-scale-up services positions the company as a practical partner for manufacturers evaluating bio-based material adoption within their current injection molding infrastructure.
