Block Lap-Shear Results. For laminated maple wood, this work indicated a maximum of 40% of the PF resin solids can be replaced with OSL without... 

It has been demonstrated that red oak OSL could be used to replace 35% to 40% of the phenol (or phenolic resin solids) in phenol-formaldehyde resins used to laminate maple wood and to bond southern pine flake boards (wafer-board and/or strandboard) without adversely affecting the physical bond properties. While this pulping process and by-product lignin do not commercially exist at this time in the United States, lignins from such processes are projected to cost 40% to 50% less than phenol as a polymer raw material. 

Tennessee Whiskey. Tennessee whiskey is a product made by Tennessee distillers and processed in a manner similar to bourbon. However, Tennessee whiskey is filtered through maple charcoal prior to maturing which gives it its distinctive flavor. Tennessee distillers make their own charcoal by slowly burning 1.8-m lengths of hard maple wood. During the burning process the wood is periodically wet down to cause it to char rather than...

Polymers. Nlcolson and Ross, using the methods developed for solid discs of material, examined the permittivity and prarmeability of a number of polymeric substances, and the results are given in Figure 14 for a sc of maple wood, the only one of their samples to exhibit any detectable loss in the frequency range 0.4—10 GHz.

Without extraction with polar solvents the Nq/Nq ratios were regularly much lower. These ratios were well below those of cellulose and lignin for maple wood and pine wood, amounting to 0.15 and 0.26, respectively. The extraction effect was due to nonpolar wood extractives no effort has been made to identify these extractives. Although the likelihood of extractives covering the surface cannot be...

ABS shows higher water absorption (0.3% after 24h nnderwater, 0.7% at satnra-tion) compared to HDPE, PP, and PVC (less than 0.01,0.01, and 0.1%, respectively). However, an ABS-based WPC, containing 50% w/w of 80-mesh maple wood flonr, showed a very reasonable water absorption performance, namely 5.5% after 10 days, 8% after 20 days, and 9.5% after a month [16]. These valnes are similar with those for many HDPE-based WPC prodncts. 

Tables 4.28 and 4.29 show effect of a montmorillonite nanoclay employed as a masterbatch (PolyOne Nanoblend 1001) in polypropylene on polypropylene-based composite containing 50% (w/w) maple wood flour and on flexural strength and modulus of the WPC.

Nanoparticles can increase water absorption by WPCs. For example, after a month of underwater exposnre of the WPC (50% polypropylene -l- nanoclay, w/w, 46% maple wood flour [80-mesh], and 4% conpling agent) no-nanoclay composite absorbed 2.7% of water, 4%-nanoclay composite absorbed 2.9% of water, and 10%-nanoclay composite absorbed 4.4% water [24], It also makes nanoparticles undesirable in WPC prodncts, nnless some means are found to overcome this problem. 

Even Inbricants can contribnte to mold growth. Zinc stearate (6%) noticeably increased mold snsceptibility of the WPG, a blend of HDPE (24-28% w/w) and maple wood flonr (70% w/w), and a clear dose response was observed. It was noticed that the higher Inbricant content, the more was the mold growth [11]. 

Other data on zinc borate efficiency against molds are less optimistic. For example, 1% of zinc borate practically did not effect mold development on a 60-mesh maple wood flour (70% w/w)-filled HDPE (Table 13.3). Only 3 and 5% of zinc borate were effective (Table 13.3).
