When color consistency can make or break a production run — and a brand’s reputation — who you choose as your masterbatch supplier matters more than ever.
Who We Are: 26 Years Rooted in Masterbatch Manufacturing
Behind every vibrant plastic product on the shelf — the crisp white of a home appliance, the rich black of an automotive interior, the precise green of an agricultural film — there is a color masterbatch that had to be formulated, tested, and delivered with absolute consistency.
That is what Guangdong Tianhao New Materials Technology Co., Ltd. has been doing since 2000.
Founded and headquartered in Dongguan, Guangdong Province — one of China’s most important manufacturing hubs — Tianhao has grown from a local color concentrate workshop into a modern, integrated enterprise that covers R&D, production, sales, and technical services under one roof. For 26 years, we have focused on one thing: helping plastics manufacturers around the world achieve the exact color, performance, and quality their products demand.
We are not a trading company. We are not a middleman. We are a factory-direct manufacturer with real production lines, real testing laboratories, and real people who understand the chemistry and engineering behind every kilogram of masterbatch we ship.
What We Make: A Full Spectrum of Color and Functional Solutions
Our product portfolio is built around the reality of modern plastics processing. Whether you are running blown film lines in Southeast Asia, injection molding machines in Latin America, or extrusion equipment in the Middle East, we have a masterbatch solution that fits your process.
Color Masterbatch — Custom and Standard
We produce color masterbatch for virtually every major processing method:
- Blown film masterbatch — for shopping bags, garbage bags, agricultural mulch films, and food packaging films
- Injection molding masterbatch — for household items, appliance housings, automotive parts, and consumer goods
- Pipe masterbatch — for HDPE water pipes, PVC conduits, PP-R hot water pipes
- Wire & cable masterbatch — for insulation and jacketing compounds
- Sheet masterbatch — for thermoformed packaging, construction panels, and stationery
- Blow molding masterbatch — for bottles, containers, and jerry cans
- Extrusion masterbatch — for profiles, window frames, and fencing
Every formulation is supported by Pantone color matching. Send us a Pantone number, a physical sample, or a photo reference — our technical team will match it.
Functional Masterbatch — Beyond Color
Color is only half the story. Modern plastic products often need more than appearance. Our functional masterbatch line adds performance properties directly into your resin:
- Pearlescent masterbatch — for luxury packaging and cosmetics containers
- Fluorescent masterbatch — for safety equipment, signage, and promotional items
- Marble-effect masterbatch — for decorative panels and home improvement products
- Anti-static masterbatch — for electronics packaging and industrial films
- Slip & anti-block masterbatch — for improved film handling and processing
- Antibacterial masterbatch — for food contact items and medical supplies
- Biodegradable masterbatch — supporting the transition to sustainable materials
- Thermochromic masterbatch — color-changing effects triggered by temperature
Broad Resin Compatibility
Our masterbatches are compatible with PE, PP, PS, PC, PO, ABS, PVC, PET, PLA, PHA, EVO, and other custom resin systems. Whatever your base material, we can formulate a carrier resin that ensures optimal dispersion and processing stability.
| Market Segment | Typical Applications |
| Flexible Packaging | Food packaging film, shrink wrap, stretch film, heavy-duty sacks |
| Rigid Packaging | Bottles, caps, closures, containers, trays |
| Household Appliances | Washing machine panels, refrigerator liners, air conditioner housings |
| Building & Construction | PVC pipes, window profiles, flooring, roofing membranes |
| Agriculture | Greenhouse films, mulch films, silage covers, irrigation pipes |
| Wire & Cable | Power cable jacketing, communication cable insulation |
| Consumer Goods | Toys, stationery, kitchenware, furniture components |
| Tableware & Food Contact | Disposable cutlery, cups, lunch boxes, food storage containers |
We understand that each market has different requirements. Food contact applications need FDA-compliant materials. Agricultural films need UV stabilization and multi-year weatherability. Appliance manufacturers need batch-to-batch color consistency across production runs that may span months. We formulate accordingly.
Certifications: Quality You Can Verify
In B2B masterbatch supply, certifications are not decoration — they are the foundation of trust. Tianhao’s quality management system and product compliance are verified by internationally recognized standards:
- ISO 9001:2015 — Certified quality management system covering our entire production and service workflow
- SGS — Third-party testing and verification for product safety and conformity
- ROHS — Restriction of Hazardous Substances compliance for electronic and electrical applications
- REACH — European Union chemical safety regulation compliance
- FDA Food Grade — Approved for food contact applications
- Every shipment is supported by the documentation you need: Certificate of Analysis, Safety Data Sheet, and relevant compliance certificates.
Customer Cases: Real Problems, Real Solutions
While we respect the confidentiality of our customers’ brands, the following are representative examples of how Tianhao’s masterbatch solutions have helped manufacturers overcome real production challenges:
Case 1: Reducing Downtime for a Southeast Asian Packaging Manufacturer
A blown film producer in Vietnam approached us with a recurring problem: their existing black masterbatch supplier delivered inconsistent dispersion, causing visible specks and gel formation in the film. This led to excessive downtime — up to 6 hours per week for screen changes — and a rejection rate of nearly 5%.
Our solution: We analyzed their LDPE/LLDPE blend, processing temperature profile, and film thickness requirements, then formulated a custom black masterbatch with optimized pigment loading and a carrier resin matched to their specific extrusion conditions.
The result: Dispersion quality improved to the point where screen changes dropped from daily to once every 5–7 days. Rejection rates fell below 0.5%. The customer increased their order volume by 40% within six months.
Case 2: Matching a Brand Color for a Latin American Home Appliance Manufacturer
A white goods manufacturer in Colombia needed a specific shade of appliance white for their new refrigerator line — a cool-tone white that had to match across injection-molded interior components and thermoformed door liners, both produced in different factories using different base resins (PP and ABS).
Our solution: We developed two masterbatch formulations — one PE-based for the PP components, one specifically designed for ABS — both targeting the same Pantone reference. After two rounds of sample adjustment, we locked in the formula.
The result: Color consistency between the two factories was achieved with a Delta E of less than 0.8. The appliance line launched on schedule, and Tianhao became their designated masterbatch supplier for the entire product series.
Case 3: FDA-Compliant Colorants for a Middle Eastern Disposable Tableware Producer
A tableware manufacturer in Saudi Arabia was expanding into the European market and needed their entire color range — white, beige, and pastel blue — to comply with EU food contact regulations, including specific migration limits.
Our solution: We reformulated their color masterbatch series using FDA and EU 10/2011-compliant pigments and additives, provided full migration test reports through SGS, and adjusted the let-down ratio to optimize opacity at lower addition rates.
The result: The customer passed EU border inspection on their first container shipment. They have since placed regular quarterly orders covering all three colors.
