Bio-based Epoxy Resin Synthesis and Their Application Evaluations
■ Technology Overview
The global epoxy resin market will reach US$6.4 billion in 2020, and the value of derivative applications will reach over US$800 billion. Since the "2050 Carbon Neutrality" target and timeline were announced
successively in Taiwan, the epoxy resin companies began to look forward to using sustainable materials to meet low carbon emission requirements. The technology utilizes HMF derivative from nature to develop high-purity bio-epoxy resins with a patented catalyst. Such products are not only expected to reduce dependence on petrochemical raw materials but also have the benefit of reducing carbon emissions.
■ Features
• Novel catalyst design to unify the reaction mechanism
• Reduce the side-products and improve the yield
• Drop-in DGEBA process
• Properties similar to DGEBA resin
■ Applications of Derivatives
• Corrosion resistant coating
• High Tg CCL
• Carbon fiber composite
• Reduce carbon footprint of application products
Functional Polyphenol Extraction Technology and Application Development
■ Technology Overview
The extracting of functional polyphenols from agricultural waste in Taiwan using advanced technologies such as process design, optimization, separation, purification, and identification. These extracted polyphenols can have various applications in food packaging, agriculture, animal materials, textile, shoe deodorization, and vehicle filters. Additionally, the laboratory technology combined with relevant experience in the scale-up process can be used to trial-produce a range of fine chemicals for product verification and evaluation.
■ Features
• Active molecules identification
• Functional modification
• Formula design for coating/compounding
• Trial production process design and optimization
• Characteristic evaluation
■ Applications of Derivatives
• Specific material extracted from agricultural wastes
• Food packaging
• Agricultural/Animal products
• Textile/Shoe
• Vehicle filters
The Pretreatment Technique for the Polyester Fabric Recycling
■ Technology Overview
The annual production of polyester fiber exceeds 50 million tons, while the recovery rate is less than 3%. The development of the industry is hampered by poor decolorization and re-dye ability. Therefore, the current recycled products are mostly used for low-end applications, which stops the investment from brands. Our team has developed pretreatment technology for dyed polyester fabrics that can be combined with current mechanical and chemical recycling processes to improve the re-dye and reusability of recovered polyester fibers.
■ Features
• Good solubility for wide-range of color dyes
• Highly efficient dye-removing for polyester fibers
• Easy to import the current recycling process
• Good re-dyeability of recycled fibers
■ Derivative Applications
• Dyed 100% polyester fabrics
• Dyed blending fabrics (T/C, OP)
• Dyed polyurethane fabrics (Spandex)
• Separation for blending fabrics of cotton and polyester
