M.D.F Board?
What is MDF made from that makes it so toxic.. said to be more dangerous than asbestos? If so why is asbestos mainly banned & handled by specialist removal companies whilst everybody has access to MDF & used in just about every home in the land?
Answers:
MDF board is essentially the byproducts of saw mills glued and pressed together. These board are almost as strong as plywood but with less cost. The toxicity of them is derived from the glues, resin, etc as stated in an earlier message. While the toxins in these boards can be hazardous, they generally are not released into the environment unless the board becomes soaked for long periods of time and then you'd practically have to drink the water to get enough toxins to be hardfull.
Asbestos is another thing all together. Asbestos was found to be extremely fire retardent years ago and the thought back then was to use is in somewhat the same fashion as MDF but for more lightweight things ceiling tiles, insulation, etc. The problem with Asbestos is that along with being toxic it is also micro-pariticle based. Which means that when an Asbestos based product is broken or burned these particles are released into the air. These small microscopic particles then float along into unsuspecting lungs creating all sorts of problems such as lung cancer and asbestosis.
Hope this answered your question!
Formaldehyde, resins, glues, etc.
medium density fibreboard, that is all i currently know about mdf
Its not just the ingrediants; its the fact that when you cut it you generate those ingrediants as very fine particles, which makes them more dangerous when inhaled.
First of all asbestos is and absolutely fabulous product. The problem is when the dust is inhaled into the lungs. You can eat asbestos but not breath in the dust. As far as MDF goes, it is medium density fiberboard that is made of sawdust like material and bonded together under extreme pressure and heat. That is why MDF is so dimensionally stable and an excellent product for speaker enclosures. When cutting MDF it is the dust that is harmful. You should be using an appropriate dust mask for small home projects or a respirator for commercial jobs. If you do tile work or concrete the dust from that also is harmful if inhaled. Think of it like this, if you took a sock and filled it with whatever dust or material you’re producing, then ran water through it, what would it look like? That is what you should picture it might look like in your lungs. Be safe, be smart, use the APPROPRIATE personal protective equipment (PPE). If you are going to Menards, Home Depot, Ace, or Lowes to get a dust mask, have someone help you out because some are for paint, some are for dust. Also, have them show you how to make sure it fits correctly.
mdf is "toxic" only when it is being cut or sanded as it is the fibres that can do you harm so use p.p.e (personal protective equipment.)
Medium-density fibreboard
Medium-density fibreboard (MDF), is an engineered wood product formed by breaking down softwood into wood fibres, often in a defibrator, combining it with wax and resin, and forming panels by applying high temperature and pressure.
Large-scale production of MDF began in the 1980s. Its name derives from the distinction in densities of fibreboard. MDF typically has a density of around 800 kg/m³. Low density fibreboard, such as caneite, ranges in density from 160 to 450 kg/m³, while high density fibreboard, such as masonite, has a density of around 1000 kg/m³. The same manufacturing process is used.
MDF is useful in many applications, particularly where particleboard was previously used. It is not useful for outdoor use because it will swell upon contact with water; nonetheless, it has better moisture tolerance than particleboard. Because MDF is fibre-based, it has a remarkably consistent structure. This quality makes it easy to machine or employ in woodworking applications. MDF is often used with melamine or wood veneers.
One contentious issue is the use of formaldehyde resins and the associated health risks. Thus, other resins are being introduced.
