(UPM, Lahti, November 6, 2009 at 10:00 EET) UPM Plywood is pleased to announce that certain of its WISA products have been granted the California Air Resources Board (CARB) certification for low formaldehyde emission released from the panels. The certification applies to WISA-Birch plywood manufactured at Jyväskylä, Chudovo and Otepää mills as well as WISA-Spruce and WISA-Twin plywood manufactured at the Pellos mill. The certificate is required for all composite wood products sold to the state of California and it provides a useful reference to evaluate formaldehyde emission levels in other markets.
The CARB airborne toxic control measure to reduce formaldehyde emissions from composite wood products is the most stringent production-based standard in the world. The control measure limits emission of formaldehyde from composite wood products, including hardwood plywood, in two phases. The Phase 1 limit as of January 1, 2009 is 0.08 particles per million (ppm) and Phase 2 limit as of January 1, 2010 0.05 ppm. The certified WISA plywood products already conform to the Phase 2 limits.
Formaldehyde is released, amongst other sources, from wood binding adhesives and resins used in plywood manufacturing. WISA plywood products are constantly developed and tested to ensure that they cause no risk to health and that they are safe to use and when disposed. Reducing the formaldehyde levels in our plywood panels is a continuous development area and our ultimate goal is to eventually eliminate added formaldehyde from our products altogether.
