Company information,
We are the biggest manufacturer in China that currently produces strawboard is our business relation, which was founded in Feb, 2006 by 5 shareholders . The operating activities conver the research, develpment and manufacturing of WanHua ECOBoard and its eco-additives. WanHua is the largest straw ecoboard supplier worldwide.. The company strictly adheres to the doctrine “Utilizing One-hectare Straws, Protecting a Forest, Innovating the Green Material Industry”, taking up with development and application of “zero-formaldehyde” straw, to reduce the natural resources waste and protect forestry and environment.
We have a complete set of facilities of straw board products, devices and adhesives and excellent staff committed in the R&D projects. Our company is also the first high-tech company specialzed in production, tech-introduction and researching fields of straw board industry, and the pioneering enterprise who realized the inter-industries integration of eco-friendly adhesive, manufacturing devices and board production. We have significantly outperformed our competitors in product quality.
General characteristics
Moisture Resistance: Unlike traditional wood based boards ECO-Boards are extremely moisture resistant and are specified for use in the most strenuous humid domestic interior conditions where dimensional stability and retained strength are of great importance such as Kitchen & Bathroom furniture, skirting boards, wall cladding, flooring, etc.
Fire Resistance: ECOBoards are standard >20min fire resistant - non rated , since they scorch rather than burn, in addition ECOBoards has a full range of fire rated panels and door cores to fit most applications.
High Strength, Lighter Weight: The High strength to lighter weight ratio of the ECOBoard panels further eases panel handling (manufacturing plant, construction site).
Screw Tightness: The tenacious screw holding ability adds flexibility to the choice of fitment hardware that can be used (hinges, brackets, screw types).
Machinable: ECOBoard Bio-Composite Panels are made in a Single Layer process giving homogenous consistency throughout its thickness, similar to MDF. The Single Homogeneous Layer and Its superior internal bond (cross tensile) allows smooth strong profiling and sharp machined edges. Less dust and released toxins allows a cleaner and healthier working environment. Tools show less ware and tare.
Finishing: When sanded to agrifibers create an excellent finish and readily accept Paper and Foil Laminates, Melamine, Formica and Natural Wood Veneers. Painting after priming gives excellent results.
