Is Safe formaldehyde-free plywood ?

       Formaldehyde is a chemical with many industrial applications. one of the largest of these is in plywood. about 64% of the formaldehyde produced worldwide used in plywood. or other wood products such as particleboard. 


       The resin used to make most manufactured wood products is formaldehyde-based. In plywood, many layers of wood glued together using a resin. This resin must be cheap, durable, and water-resistant. The most common type of resin used is urea formaldehyde, or UF. Another type, purebond plywood and  phenol-formaldehyde (PF) intended for exteriors forest products.


       When we say plywood made is “formaldehyde-free“.  we’re describing the way our hardwood plywood panels. comprised of no added formaldehyde components. and assembled with no added formaldehyde adhesives.


      What makes formaldehyde free plywood special is that. it’s cost-competitive with the standard UF construction. of most decorative veneer core hardwood plywood that’s made today. That means formaldehyde-free plywood is less expensive than. many other no-added-formaldehyde alternatives currently available.


       Additionally, formaldehyde free plywood is even more water resistant than UF panels. columbia forest panels with formaldehyde-free technology have out performed UF bonded panels. in all moisture degradation tests. This award-winning innovation can be yours for . what you’d pay for traditional veneer core hardwood plywood green building options.


What is  Formaldehyde  


       Formaldehyde is a naturally-occurring organic compound. A colourless and strong-smelling gas, formaldehyde emitted by all timber species. as well as by processes like decay and combustion. It has become a very important ingredient in the production of industrial resins. including the adhesive that used to bond plywood products.


      Formaldehyde is a strong-smelling. and colorless gas that induces both short-term and long-term health issues. The immediate effect of formaldehyde is that it can make you feel sick it. if it is present in the air at levels higher than 100 parts per billion (ppb). 


       A helpful comparator is that the average indoor formaldehyde level in most US homes today is. around 25 parts per billion. Some people will experience sensitivity with lower levels than 100 ppb. symptoms include sore throats, coughing, scratchy eyes, and nosebleeds. Children and the elderly can be particularly sensitive to formaldehyde exposure.


       Long-term exposure to high levels of formaldehyde. seen in workers in industries that make formaldehyde. or formaldehyde-containing products (as well as lab technicians. some health care professionals, and funeral home employees). has shown to cause cancer. 


       The United States Environmental Protection Agency (EPA) lists formaldehyde as.  a “probable human carcinogen".  while the International Agency for Research on Cancer (IARC) . classifies formaldehyde as “carcinogenic to humans.”

 

Application prospects of formaldehyde-free plywood


formaldehyde emissions  standard  


        As for the formaldehyde release content. countries all over the world have different standards to measure it. the detection value of plywood added urea formaldehyde. generally meets the national environmentally friendly standard E1 level. which can meet the national standard. but even if the formaldehyde capture reaching the national standard E0 level,


      formaldehyde will still release within 3-15 years. it still cause potential harm to human body. With the popularization of national environmental protection and the environmental protection  awareness. as well as the successive implementation of international environmental protection standards in north american,


       The national standard E0 environmental protection standards:

(formaldehyde emission less than 0.5mg/L). can no longer meet the development of international environmental protection trends


        In such a world environment, plywood building materials industry must upgrade its previous production system. Level 1. the leading domestic industry: 


         China Heilongjiang Baijia Biomass Material Co., Ltd. lead in breaking through the technical difficulties. developed the aldehyde-free adhesives with biomass as the main body. and through the application in the same industry. realized theproblem of producing aldehyde-free plywood without changing the existing industry production pattern. It paved the way for formaldehyde-free plywood industry in China. 


     Actually, purebond hardwood sell in home depot. which belong to purebond® hardwood. or purebond® technology. their wood species in better


Is Safe formaldehyde-free plywood ? 


       With formaldehyde classified as a chemical with cancer-causing properties. it is but natural for people to concerned about formaldehyde in plywood. After all, formaldehyde emissions are to expected in all pressed wood plywood. that has bonded with a Phenol Formaldehyde adhesive.


There is, but, very little actual cause for concern.


       Sure, formaldehyde emissions from plywood tend to be at their highest immediately. after the manufacturing process. Within a few weeks, but, these formaldehyde emissions subside . The application of a phenolic coating further reduces emission levels. By the time plywood products bonded with Phenol Formaldehyde reach your plywood supplier. their formaldehyde emissions will have become close to negligible.


       It is very important to keep in mind that while formaldehyde may be carcinogenic. it only rears its ugly cancer-causing head when at very high concentrations. As stated earlier, formaldehyde emissions from plywood products deemed very low. In fact, these emissions are so low. that plywood products are exempt from formaldehyde emission regulations in Europe. and in the United States.
