ON MODIFIED WOOD - MOISTURE PROPERTIES, BIOLOGICAL RESISTANCE AND MICROMORPHOLOGY . CHARACTERISTICS OF WOOD PLASTIC COMPOSITES both injection and extruded molded samples made with an WPC unmodified, acetylated, thermally modified or furfurylated wood component in a polypropylene PP , high density polyethylene HDPE , strength losses
Glasser et al. observed similar results on acetylated or benzoylated fiber-based WPC with good dispersion of the esterified fibers in the HDPE matrix that provided effective stress transfer and increased tensile strength. Benzoylated and propionylated fiber based WPC had higher tensile moduli than the acetylated fiber WPC.
Wisconsin Center for Dairy Research permeate is a byproduct of whey protein concentrate WPC or ultra filtered UF milk production. Permeate actually is a term used to cover a family of products. They have a minimum of 59% lactose, maximum of 10% protein and
2007 reported that when 50 wt.% acetylated wood particles were combined with cellulose acetate propionate or polypropylene PP , the tensile strength was approximately 40% higher than that of unmodified WPC, whereas their notched impact strength was 20% lower than those of the corresponding unmodified composites.
This study describes the preparation of acetylated wood meals through mechanochemical processing, and the resulting acetylated wood meals are used as materials for WPC production, because the use of chemically modified wood such as acetylation is known as a method to improve dimensional stability and biological durability of WPCs 2, 3, 4, 5 .
Fading, chalking, and strength weakening caused by environmental exposure are major problems for WPC in outdoor applications. In this study, acetylated BPCs had improved in mechanical properties and mildew resistance, but nor discoloration compared to unmodified BPCs when exposed to natural weathering.

WPCs and acetylated wood, 40% higher than that of unmodified WPC, whereas their notched impact strength was 20% lower than those of the corresponding unmodified composites. Bledzki et al. 2008 found the following effects of acetylation on the mechanical properties of flax fibre-PP
biological durability, and mechanical performance of injection-molded WPC samples based on acetylated or thermally modified wood components and a polylactate matrix. The wood components used were in the form ofboth wood flour and wood fiber intended
Shanghai Seven Trust Industry Co., Ltd, founded in the year 2008, is a hi-tech enterprise which specializes in the R&D, sales, and service of WPC materials, Provide excellent products, professional technology and sincere service.
