Tea Fiber PP Composite

WYC-PP P179402N

Tea Fiber PP combines polypropylene with refined fiber from Tieguanyin tea shoots and leaves. The material develops a muted green-beige to gray tone with fine dark leaf specks, and it may retain a mild herbal tea aroma depending on processing. Its molded surface feels dry and lightly textured while remaining sufficiently uniform for clearly shaped everyday parts. This distinctive leaf-derived appearance works well for tea trays, desk organizers, plant pots, storage accessories and pet products where a calm, natural visual effect is preferred.

Usage Guidelines and Processing Notes

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.

Color matching

Color matching is supported within a limited range. Because the natural base is dark, select dark color families; pale or bright colors cannot reliably cover the original tone. 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

StageReference setting
Drying100–120 °C for 4–5 h
Rear zone155–165 °C
Middle zone160–175 °C
Front zone160–175 °C

Mold50–60 °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.
