R&D
GREENPOLYMER's R&D is built around your part: what performance it needs, which formulation delivers it, and how to keep it stable in mass production. We focus on four areas: flame safety, structural strength, appearance and environmental performance.
Compounding toolbox
Compounding means adding other components to a base resin to change its properties. Methods we often use:
Adding glass fiber or carbon fiber for higher strength, stiffness and heat resistance.
Adding elastomers for higher impact strength, especially at low temperatures.
Adding halogen-free flame retardants such as phosphorus-based or silicone-based systems to reach the target flammability rating.
Adding mineral fillers to adjust stiffness, dimensional stability and cost.
- Strength
- Stiffness
- Heat resistance
- Impact strength
- Flammability rating
- Dimensional stability
- Cost
- Functions
- Color
Mixing two or more resins, such as PC and ABS, to combine their strengths.
UV resistance, hydrolysis resistance, antistatic, thermal conductivity and more.
Colors are set at the pelletizing stage.
R&D areas
Halogen-free / fluorine-free flame retardancy
- Problem to solve
Meet the flammability rating while also being halogen-free and PTFE-free
- Related materials
Structural reinforcement
- Problem to solve
Replace some metal parts with plastic to reduce weight
- Related materials
Appearance and color
- Problem to solve
Mold-in-color (paint-free), high gloss, consistent color
- Related materials
Recycled material applications
- Problem to solve
Use recycled material where performance and appearance remain acceptable
- Related materials
Each method affects other properties. For example, adding flame retardant can lower impact strength. The core of R&D work is finding the balance between these properties.

Application evaluation
Specimen data cannot fully predict how a part performs. Where possible we evaluate materials at the part level:
- Flammability at the actual wall thickness;
- Screw boss fastening and snap-fit assembly;
- Low-temperature drop and impact;
- Retention of appearance and properties after damp heat and xenon-arc / UV aging;
- Cracking after contact with chemicals such as cleaners and grease.
Test items are set by your standards and test conditions. Part-level testing capabilities: [to be verified by GREENPOLYMER]
Mold flow analysis support
A material's flow length, shrinkage and fiber orientation affect filling, weld lines and warpage. We can provide the material data needed for mold flow analysis and discuss the results and improvements with your mold team. Scope of material card data: [to be verified by GREENPOLYMER]

3D printing materials R&D
We apply our formulation and color matching experience from injection molding compounds to 3D printing materials. Printing materials also require work on diameter stability, interlayer adhesion, printing temperature window and warpage control. Products and R&D progress are on the filament pages.
