Introduction
LIHUI ENVIRONMENTAL PROTECTION NEW MATERIAL CO., LTD. (衡阳立辉环保新材料有限公司) is a Chinese specialized plastics-related materials manufacturer focused on black masterbatch, carrier-free colored sand, and PVC-specific color paste. Company information published through CHINAPLAS identifies its production lines as domestically advanced and states that its products rank among the top in China in these niche categories.
The company is based in Hengyang, Hunan Province, and is positioned within the broader industrial ecosystem of polymer compounding and colorant materials used in plastics processing. Chinese government records also list the company among Hunan’s specialized and innovative small and medium-sized enterprises, indicating recognized specialization in its segment.
History and Development
LIHUI ENVIRONMENTAL PROTECTION NEW MATERIAL CO., LTD. was established on 23 June 2016 as a limited liability company in the PRC. The company later expanded its capital base in December 2017, then completed a corporate conversion into a joint stock company in November 2020.
A major corporate milestone came in February 2023, when the company listed its A shares on the ChiNext board of the Shenzhen Stock Exchange under stock code 301358.SZ. This listing suggests a transition from a privately held industrial materials business into a publicly traded enterprise with broader capital-market access.
The company has also emphasized manufacturing capability development, including the establishment of a headquarters and production base in Hunan Province and the achievement of 100% self-sufficiency in iron phosphate supply as part of its broader materials platform. While that latter point relates to its battery-materials business line in the cited listing document, it indicates a strategic focus on process control and upstream integration.
Business Operations and Segments
The company’s public CHINAPLAS profile presents it as a manufacturer of specialized environmental protection new materials serving plastics and related processing markets. Its identified product lines indicate a business model centered on pigment masterbatches, plastic colorants, and functional additive materials rather than consumer-facing finished goods.
Its operations can be understood in three practical segments:
- Color masterbatch manufacturing, especially black masterbatch for polymer coloration and processing.
- Specialty color materials, including carrier-free colored sand and PVC-specific color paste.
- Technical process manufacturing, supported by advanced domestic production lines and a specialization profile recognized by Chinese industry programs for SMEs.
This positioning places LIHUI in the supplier tier of the plastics value chain, where consistent dispersion, color stability, and process compatibility are critical to downstream processors.
Products and Technologies
The company’s publicly cited product portfolio is centered on:
| Product category | Typical role in plastics processing | Notes from available sources |
|---|---|---|
| Black masterbatch | Provides color and sometimes UV or process-related functional performance in polymer products | Listed by CHINAPLAS as a core product line. |
| Carrier-free colored sand | Specialty decorative or functional color material | Identified as a main product category in CHINAPLAS materials. |
| PVC-specific color paste | Colorant formulation tailored to PVC applications | Identified as a main product category in CHINAPLAS materials. |
From a technical standpoint, masterbatch producers typically compete on dispersion quality, color consistency, thermal stability, and compatibility with resin systems. LIHUI’s description of “domestically advanced production lines” suggests a manufacturing emphasis on process control and repeatability, which are essential for color uniformity in plastics applications.
The company’s designation as a specialized and innovative enterprise further implies a focus on process refinement, product differentiation, and relatively narrow but technically demanding applications. However, the available sources do not provide detailed specifications such as melt-flow characteristics, additive packages, or resin compatibility matrices, so those aspects cannot be stated definitively.
Applications and End Markets
Based on the company’s stated product categories, LIHUI’s materials are likely used in downstream sectors requiring polymer coloration and formulation support, including:
- Plastic product manufacturing
- PVC processing
- Decorative and functional material applications
- Industrial compounding and extrusion-oriented use cases
The sources do not provide a full end-market breakdown, but the product mix suggests the company serves processors seeking coloring solutions rather than large-volume commodity resin production.
Global Presence and Market Position
CHINAPLAS materials describe the company as having a domestic market position with products that “rank among the top in the country” in its niche categories. This indicates strong recognition within its specialized segment, although no independent market-share figure is provided.
The company’s appearance in a major industry exhibition platform also indicates participation in broader plastics-industry commercial networks, which is often important for technical suppliers seeking processor customers, distributors, and OEM relationships.
Sustainability and Environmental Initiatives
The company’s name and product positioning emphasize environmental protection new materials, but the available sources do not provide detailed environmental-performance metrics, emissions data, or formal sustainability targets. As a result, any direct claim about its environmental impact would go beyond the evidence provided.
More generally, masterbatch and colorant producers in the plastics industry face pressure to improve formulation efficiency, reduce waste, and support downstream recyclability, but LIHUI’s specific initiatives in these areas are not documented in the cited materials.
Financial Performance and Economic Impact
Publicly available excerpts confirm the company’s ChiNext listing in 2023, which indicates access to capital markets and subjecting the business to public reporting requirements. Beyond that, the provided sources do not include revenue, profit, export, or segment-level financial figures for the company.
Its recognition as a specialized SME and its inclusion in industrial exhibition and government-related listings suggest a measurable regional industrial presence in Hunan’s materials sector. However, the scope of its economic impact cannot be quantified from the available evidence.
Leadership and Corporate Governance
The sources provided do not include a full current management roster, board composition, or governance disclosures beyond the company’s corporate history and public listing status. What can be stated is that the firm transitioned from a private limited company to a joint stock company before its stock-market listing, which generally implies a more formal governance structure and disclosure framework.
Innovations and Future Outlook
LIHUI’s future development appears likely to depend on three factors:
- Process innovation in masterbatch and colorant formulation
- Capacity and quality control to maintain consistency in specialized plastic materials
- Market expansion through exhibition platforms and industry recognition
Its classification as a specialized and innovative enterprise suggests continued emphasis on technical differentiation rather than commodity-scale competition. If the company continues to strengthen formulation performance and downstream compatibility, it is well placed to remain relevant in China’s plastics colorant and specialty materials market.
Summary
LIHUI ENVIRONMENTAL PROTECTION NEW MATERIAL CO., LTD. is a Hunan-based specialty materials company focused on plastics-related colorants and masterbatch products, with a public-market listing and recognition as a specialized and innovative enterprise. Its published profile indicates a business built around technically focused, domestically advanced production lines serving niche markets in polymer coloration and PVC-related materials.
