In May 2013, Rentech announced it had acquired the shuttered Weyerhaeuser oriented strandboard
mill near Wawa and former Atikokan Renewable Fuels.
(OSB) panels were produced with these laboratory-synthesized LPF resins for evaluating the bond performance of the LPF resins in the manufacturing of wood composites.
The panels usually consist of plywood, oriented strandboard
, or drywall glued and sandwiched around a core consisting of expanded polystyrene, polyurethane, polyisocyanurate, compressed wheat straw, or epoxy.
They used oriented strandboard
- similar to plywood - for the stadium wall, anchoring it with 4-by-4s and strengthening it with angled 2-by-4s.
, for one, didn't exist 50 years ago, Keegan pointed out.
These member companies produce lumber, plywood, oriented strandboard
, particleboard, medium density fiberboard and value-added products.
Other pressed wood products, such as softwood plywood and flake or oriented strandboard
, are produced for exterior construction use and contain the dark-colored phenol-formaldehyde (PF) resin.
But work is under way at Oregon State University to commercialize the patented formaldehyde-free wood adhesive for production of particleboard, medium-density fiberboard, exterior-grade oriented strandboard
, and plywood.
The analysis also includes projected expansion of roundwood demand at wood panel mills [such as oriented strandboard
(OSB)] in the total pulpwood supply and demand outlook.
Construction markets are dominated by the use of phenolic and amino (urea and melamine) adhesives as binders in wood panels such as plywood, oriented strandboard
The emerging threat posed by the oriented strandboard
(OSB) industry on Canada's remaining aspen stands will be the new battle lines on which the industry, environmentalists, First Nations and northern communities will converge.
He held up pictures of new houses going up in nearby Madras -- not framed with plywood, but with oriented strandboard
