- Bio-based materials and related R&D
- Technology development, consulting, transfer, and import-export services
Company materials describe four core product systems under its PC and PC alloy additive platform, including YIMA flame-retardant systems, KINGFOX impact-modification systems, FLYHO anti-dripping systems, and SA specialty functional additives. This structure suggests a formulation-oriented business model in which the company supplies additive packages tailored to end-use performance requirements rather than offering a single standardized chemical product.
The company also reports technical work in epoxy electronic materials additives under the ESUNHT series and in nylon/polyester modification additives under the ESUNBLEN line. This diversification indicates an effort to extend know-how in polymer compounding into adjacent high-performance materials segments.
Products and Technologies
EVERSUN’s core technical focus is polycarbonate modification, especially additives used to improve flame retardancy, impact strength, dripping resistance, transparency retention, and thermal stability. In industry terms, such additives are critical for PC applications where a balance is required between safety, aesthetics, and mechanical performance.
Key technology themes include:
- Flame-retardant PC systems, described by the company as offering long-term stability, efficient performance, transparency retention, and thermal stability.
- Anti-drip additives, including a disclosed product line using PTFE dispersions and fluorine-free or reduced-fluorine approaches depending on formulation.
- Impact-modifying systems for PC alloys and engineering plastics, intended to improve toughness and low-temperature performance.
- High-gloss and heat-resistant formulations, which are relevant for visible consumer and industrial parts.
- Electronic-material additive solutions for epoxy systems, reflecting a broader shift toward multifunctional specialty additives in electronics manufacturing.
Technical literature associated with the company indicates that EVERSUN has worked with PTFE emulsions and selected resin systems to create anti-dripping masterbatches, while patent records suggest research activity around copolymer, bisphenol, and chemical-reaction-based polymer modification technologies. Patent databases also indicate ownership or association with related polymer-modification inventions, although public patent search records should be treated as indicative rather than exhaustive legal proof of ownership.
A company-sponsored product description further notes that EVERSUN’s anti-dripping range was developed through a structured R&D effort led by a team that included four doctoral graduates and that the firm introduced the “Flying Monkey Clouds” trademark as part of its branding for the anti-drip family.
