Material use
Use this ready-to-process compound directly, or blend it with pure PP in any proportion to adjust the fiber concentration and molded appearance. Run a molding trial after changing the blend ratio.
Cereal Fiber PP Composite
WYC-PP P179002N
Cereal Fiber PP combines polypropylene with finely milled wheat stem straw, giving the material a pale gray-natural color with dense, small fiber marks. The fine straw distribution produces a controlled grain that is noticeable without looking coarse. Molded parts have a firm, dry surface character and retain the practical formability expected from PP-based compounds. The grade is suitable for plant pots, storage containers, clothes hangers, pet accessories and desk organizers that benefit from a subtle agricultural-fiber appearance.

Usage Guidelines and Processing Notes
Color matching
Color matching is supported. Because the natural base is light, most color families can be developed, although the plant particles remain visible and may shift the final shade. Confirm the target with a molded color sample.
Processing method
Injection molding.
Mold care
Use hardened, corrosion-resistant mold steel. Clean the mold promptly after processing, because plant-fiber composite material left in the tooling can corrode the mold if it is not removed in time.
Reference Processing Temperatures
| Stage | Reference setting |
|---|---|
| Drying | 100–120 °C for 4–5 h |
| Rear zone | 155–165 °C |
| Middle zone | 160–175 °C |
| Front zone | 160–175 °C |
| Nozzle | 160–175 °C |
| Mold | 70–80 °C |
Important: These settings are starting references only. Adjust them for the machine, mold, part geometry and residence time. Excessive temperature or residence time can scorch or carbonize the plant fiber; begin at the lower end and increase only as needed.
