Chongqing Sumi New Materials Co., Ltd.

PA6 / PA66 Modified Nylon

Standard grades and custom compounds. We develop and supply modified nylon — glass-fiber reinforced, mineral-filled, toughened, flame-retardant, cold-resistant and weather-resistant — with color and performance customization on request.

Customization

Beyond standard grades, we offer color and performance customization. Injection molding support is available as an add-on.

Color Customization

Match to physical samples, color codes or specifications; confirmation method and tolerances agreed per project.

Performance Customization

Glass-fiber reinforcement, mineral fill, toughening, flame retardancy, cold resistance and weatherability — formulated against your temperature, load, appearance and compliance needs.

FAQ

How to choose PA6 or PA66?

Selection depends on strength, heat, moisture, appearance and cost. PA66 is often stiffer and more heat resistant; PA6 is known for toughness and flow. Share your part conditions and we can help match a grade.

What information is needed for material selection?

Useful inputs: application and loads, service temperature, flame-retardant needs, appearance/color, regulatory or test requirements, and expected volume.

Can you customize color and performance?

Yes. Beyond standard modified nylon, we offer color and performance customization (reinforcement, fill, toughness, flame retardancy, cold resistance, weatherability). Scope and lead time are confirmed per project.
