Custom Color Masterbatch
Foshan, China · Serving Global Plastics Projects
Masterbatch and Modified Material Solutions Built Around Your Application
Kejulong Materials works with processors, distributors and material-development teams on color masterbatch, functional masterbatch, PP talc filler, 3D printing materials and modified plastics.
We begin with the resin, process, physical sample, final product and test requirement—then define a practical sampling and validation route.

View product direction →Application Routes
Start with the product you make, not a generic material name
Each route links the customer's process and observed problem to the most relevant material discussion.
PP thin-wall food container
Typical need: Low-odor color, thin-wall dispersion, anti-fog or stiffness direction
Useful input: PP grade, molding temperature, part thickness, sample and test method
Open application page →PP sheet and thermoforming
Typical need: Sheet stiffness, stable forming, surface and dimensional stability
Useful input: PP grade, sheet thickness, forming equipment, temperature and current formulation
Open application page →Protective and packaging film
Typical need: Color dispersion, gel control, anti-block, tack, slip, matte or PPA direction
Useful input: Resin, layer structure, film thickness, filter, equipment and defect sample
Open application page →Custom plastic color
Typical need: Black, white or custom color matched to the intended resin and process
Useful input: Physical sample or color code, resin, process, thickness and surface finish
Open application page →3D printing filament development
Typical need: PLA/PETG modification, filament color, silk effect or toughness direction
Useful input: Material, extrusion equipment, diameter, print parameters and target sample
Open application page →Modified plastic part
Typical need: Virgin or recycled material route matched to mechanical and processing targets
Useful input: Polymer, part use, process, target test, appearance and current failure
Open application page →Project Workflow
From a processing problem to a testable material direction
The goal is to define what should be sampled, processed, measured and approved—not to make an unconditional promise before the application is understood.
Define the application
Confirm the resin, process, final product, current issue, target and destination market.
Select a material direction
Discuss a relevant product category or model direction without exposing confidential formulations.
Prepare the trial
Agree on sample, dosage range, equipment, thickness, processing window and evaluation method.
Evaluate the result
Review the finished part, process record and requested test items under the agreed conditions.
Quality & Evidence
Product-specific evidence before public claims
Kejulong keeps test records, safety information and transport documents separated by submitted sample, model, test item and use condition.
Food-contact additive review
Selected submitted black and white food-container masterbatch samples have test records for specified GB 9685-related items.
The record applies only to the submitted sample and tested items. It is not a blanket statement for every model.
Plastic food-contact test items
Selected submitted samples have records for specified GB 4806.7 sensory and migration test items.
The final article, dosage, contact condition and destination requirement must still be confirmed.
US regulatory test items
Selected submitted black and white food-container masterbatch samples have records for specified 21 CFR 177.1520 extraction-related items.
This is not described as a generic FDA certification.
