Product Overview

PVC Rice Husk Compound Granules are premium raw materials engineered for manufacturing Natural Fiber Composite (NFC) profiles for outdoor applications. Unlike traditional Wood-Plastic Composites (WPC), our compound uses rice husk as the natural fiber filler instead of wood flour.

The key distinction lies in the fundamental difference between rice husk and wood flour. Rice husk contains natural silica (SiO₂), making it inherently hydrophobic, while wood flour is hygroscopic and prone to moisture absorption. This critical difference translates into superior durability, dimensional stability, and weather resistance in finished products.

As a raw material supplier, we provide compound granules that our B2B customers further process through extrusion to create a wide range of outdoor structural and decorative profiles. Our compound is designed for seamless integration into existing WPC/NFC manufacturing lines with minimal process adjustment.

· Specification

· Advantage

🔶Zero Water Absorption

Rice husk contains natural silica (SiO₂) that creates a hydrophobic barrier. Our compound achieves only 0.56% water absorption after 28 days — dramatically lower than wood flour WPC which typically absorbs 2-5%. This eliminates freeze-thaw damage in cold climates.

🔶Freeze-Thaw Durability

In Central Europe, outdoor materials experience approximately 270 freeze-thaw cycles annually (temperature drops below 0°C). Water absorbed into wood flour expands by ~9% during freezing, causing internal cracking and structural failure from within. Rice husk eliminates this failure mode entirely.

🔶Environmental Sustainability

Rice husk is an agricultural byproduct — no trees are harvested to produce it. By choosing rice husk over wood flour, you contribute to deforestation reduction. Industry data shows that producing 1 ton of rice husk composite saves approximately 2 cubic meters of timber.

🔶Superior Mechanical Properties

Rice husk fibers provide excellent reinforcement for rigidity and dimensional stability. The hollow microstructure of rice husk creates a natural fiber-matrix interlocking effect, enhancing impact resistance and flexural strength.

🔶Industry Validation

Polish manufacturer CROSWOOD SP. Z O.O. (www.croswood.pl) has validated the rice husk NFC approach with commercial success. Their outdoor profiles — including decking, cladding, railings, and garden furniture — demonstrate 15-year warranty coverage in European climates. This proves that rice husk NFC is not just theoretically superior but commercially proven.
