Performance of Fasteners in Treated Wood: A Comparative Study
2009 - IRG/WP 09-40465
Fastener performance is an important property for treated wood. Published data on screw and nail performance for different preservative systems currently on the market are, however, limited. In this study, screw and nail withdrawal strength for southern pine wood treated with ACQ (above ground and ground contact), MCQ (above ground and ground contact), borate (disodium octaborate tetrahydrate – ...

Termite Resistant Properties of Wood and Natural Fiber Plastic Composites - AWPA E1 Test Data
2009 - IRG/WP 09-40466
This paper deals with resistance properties of wood plastic composites against Formosan Subterranean Termites (FSTs) based on the AWPA E1 test standard. Sixteen laboratory WPC formulations, four WPC commercial materials, and southern pine (Pinus sp.) wood control were tested for termite mortality, sample weight loss, and sample damage rating. The results show that FSTs did attack WPC products in ...

Extruded wood plastic composites based on ACQ and MCQ-treated wood materials
2010 - IRG/WP 10-40495
This paper deals with wood plastic composites manufactured using ACQ and MCQ-treated wood fibers recovered from a wood treatment plant. The goal was to investigate the effect of coupling treatments on the properties of manufactured wood plastic composites (WPCs) through injection molding and to manufacture co-extruded WPC with treated wood fibers. The result demonstrated sound mechanical propertie...

A comparison of the resistance of pyrethroid-treated wood to damage by Coptotermes acinaciformis in Australia and C. formosanus in China and the USA
2014 - IRG/WP 14-10830
Field trials, using a single aboveground method of exposure, were used to assess a range of retentions of two pyrethroids (bifenthrin and permethrin) in Pinus radiata D. Don sapwood against two species of Coptotermes in three countries to provide directly comparable results. Coptotermes acinaciformis (Froggatt) in Australia, C. formosanus Shiraki in China and C. formosanus in the USA consumed simi...
