History and Development
Zhejiang Color Master was founded in 2005 as a plastics-coloration and polymer-materials enterprise. Its development has centered on expanding from color matching into a broader portfolio of masterbatches, modified plastics, and toll-processing services.
Key development milestones include:
- 2005: Establishment of Zhejiang Color Master in Zhejiang Province.
- Operational expansion: Development of integrated sales, production, research, and after-sales-service functions to support customer-specific material requirements.
- Technology and equipment development: Introduction of modern masterbatch production lines and computer-assisted color-measurement equipment to improve formulation control and repeatability.
- Application diversification: Expansion of product use into electronics, electrical products, daily-chemical packaging, automotive components, and other molded or extruded plastic goods.
The company’s evolution reflects a broader shift in China’s plastics industry from commodity processing toward specialized compounding, application engineering, and shorter development cycles for branded and technical products.
Business Operations and Segments
Zhejiang Color Master’s operations can be divided into four closely related areas:
| Business area | Main activities |
|---|---|
| Plastic color matching | Development of color formulations for specific polymer systems, products, and processing conditions |
| Color masterbatches | Manufacture of concentrated pigment and carrier systems for incorporation into thermoplastics |
| Modified plastics | Development and production of polymer compounds with adjusted color and performance characteristics |
| Contract processing | Customer-provided material coloring, granulation, and related processing services |
This integrated model enables the company to address both standard coloration requirements and customized projects. It also allows customers to obtain formulation, production, and technical-support services from a single supplier rather than coordinating separate pigment, compounding, and processing companies.
Products and Technologies
Color Masterbatches
Color masterbatch consists of concentrated pigments or dyes dispersed in a polymer carrier. During plastics processing, the masterbatch is blended with a base resin at a controlled addition rate. This approach can provide cleaner handling, improved dosing accuracy, and more consistent coloration than direct addition of loose pigments.
The company’s masterbatch activities are reported to include color development for a range of plastic products. Relevant technical considerations include:
- Pigment selection and compatibility with the carrier resin
- Dispersion quality and resistance to agglomeration
- Color strength and shade repeatability
- Thermal stability during molding or extrusion
- Migration, bleeding, and weathering performance where required
- Compatibility with the customer’s processing temperature and residence time
Plastic Color Matching
Color matching involves translating a target shade into a reproducible formulation suitable for a particular resin and manufacturing process. Zhejiang Color Master uses computer-assisted color-measurement equipment, including equipment associated with the X-Rite color-measurement brand, to support instrumental evaluation and formulation control.
Computerized measurement does not replace application testing. Final color performance can be affected by polymer type, surface finish, wall thickness, processing temperature, cooling conditions, and the presence of other additives. For this reason, technical color matching generally requires laboratory samples or molded plaques before commercial production.
Modified Plastics
The company also develops and produces modified materials. Polymer modification may involve the incorporation of colorants, fillers, reinforcing agents, impact modifiers, stabilizers, flame-retardant systems, or other functional additives.
Depending on the application, modified plastics may be designed to improve:
- Stiffness and dimensional stability
- Impact resistance
- Heat resistance
- Flame-retardant behavior
- Surface appearance
- Processing performance
- Color consistency and durability
Specific resin families and performance grades are not identified in the available company profile, so the product range is best understood as application-oriented rather than limited to a single polymer category.
Granulation and Contract Processing
Zhejiang Color Master provides incoming-material coloration and granulation services. In this type of operation, customer-supplied resin or compound is processed into pellets with a specified color or formulation. The service can support customers that require smaller production batches, specialized shades, or external processing capacity without establishing an internal compounding line.
Typical process stages may include material preparation, premixing, melt compounding or coloring, extrusion, cooling, pelletizing, inspection, and packaging. Process control is particularly important because inconsistent feeding, inadequate dispersion, or thermal degradation can affect both appearance and downstream molding behavior.
Applications and End Markets
The company states that its products are used in several industrial and consumer-product sectors.
Electronics and Electrical Products
Color masterbatches and modified plastics are used in housings, structural components, connectors, controls, and other electrical or electronic parts. These applications can require tight dimensional control, surface-quality consistency, color stability, and, in some cases, electrical or flame-retardant performance.
Daily-Chemical Packaging
Packaging for household, personal-care, and other daily-use chemical products commonly requires attractive and consistent coloration, good surface appearance, and resistance to contact with the packaged contents. Masterbatch selection must account for the package resin, molding method, wall thickness, and exposure to light or chemicals.
Automotive Components
Automotive plastics may include interior trim, exterior components, functional housings, and under-the-hood parts. Color systems for this market can require resistance to heat, ultraviolet exposure, chemicals, and long-term environmental aging. Modified materials may also be used when mechanical or thermal performance is more important than appearance alone.
Other Plastics Products
The company’s capabilities are also applicable to general injection-molded, extruded, and granulated plastic products. The suitability of a formulation depends on the resin, processing conditions, regulatory requirements, and required appearance or performance characteristics.
Global Presence and Market Position
Zhejiang Color Master is based in China’s Zhejiang manufacturing cluster and participates in the international plastics-supply ecosystem through material production, customer service, and industry-market exposure. Its business model is oriented toward supplying processors and product manufacturers that require customized color and material solutions.
The company’s competitive position is associated with:
- Flexible customization of shades and material formulations
- Combined color-matching and production services
- Technical support for difficult or non-standard color requirements
- Use of instrumental color measurement
- Integration of masterbatch, modified-material, and contract-processing activities

- Testing heat, light, chemical, and migration resistance
- Balancing color performance with mechanical and processing requirements
- Reducing formulation lead times for customized products
The company’s emphasis on experienced color engineers reflects the practical importance of application knowledge. A formulation that matches a laboratory standard may still require adjustment when transferred to a production line because of differences in equipment, screw design, shear history, cooling, or product geometry.
Sustainability and Environmental Initiatives
Zhejiang Color Master identifies environmentally oriented products and continued technical investment as part of its corporate approach. In the masterbatch sector, environmental performance can involve both the formulation itself and the efficiency of the manufacturing process.
Relevant sustainability considerations include:
- Reduction of pigment and additive waste through concentrated formulations
- Improved dosing accuracy compared with loose-powder additions
- Development of formulations compatible with recyclable polymer streams
- Control of volatile emissions and workplace dust
- Reduction of off-specification material through improved process monitoring
- Selection of pigments and additives consistent with applicable regulatory requirements
- Support for lightweighting and material efficiency in downstream products
Environmental performance is application-dependent. A masterbatch may improve processing efficiency or reduce waste, but its overall environmental effect also depends on the polymer carrier, additives, product lifespan, recyclability, and end-of-life treatment. Increasing regulatory attention to chemical content, recycled plastics, packaging waste, and product traceability is likely to influence future formulation and documentation requirements.
Quality Management and Technical Service
Quality control in color-masterbatch production covers both visual appearance and material behavior. Important controls may include raw-material identification, pigment dispersion, color difference, moisture, melt behavior, pellet uniformity, and batch-to-batch consistency.
Zhejiang Color Master emphasizes computer-assisted color measurement and customer follow-up services. These capabilities support a quality process that can include:
- Definition of a target color and application conditions.
- Laboratory formulation and preparation of a trial sample.
- Instrumental color measurement and visual comparison.
- Processing trials under representative molding or extrusion conditions.
- Confirmation of the production formulation.
- Batch inspection and retained-sample comparison.
- Technical assistance if the customer encounters processing or appearance problems.
