MEDITE TRICOYA EXTREME is an acetylated wood panel product. This process results in an extremely durable product with exceptional dimensional stability in changing weather conditions.
These performance attributes permit MEDITE TRICOYA EXTREME to be used in situations and applications where normal MDF panels cannot.
MEDITE TRICOYA EXTREME is a revolutionary wood based panel product, enabling its use in applications and environments that could not previously be contemplated. The raw material for the panel is modified to give outstanding dimensional stability and durability using a non-toxic environmentally compatible process.
The Proprietary technology behind MEDITE TRICOYA EXTREME is based on wood acetylation, a process that has been studied by scientists around the world for more than 80 years. This method of improving wood has been proven to deliver such superior performance that it has long been used as the "gold standard" against which other methods are measured. MEDITE TRICOYA EXTREME combines this science with years of proprietary research and investment by Accsys Technologies.
The physical properties of any material are determined by its chemical structure. Wood contains an abundance of chemical groups called "free hydroxyls" (represented as OH in the chemical formula opposite). Free hydroxyl groups absorb and release water according to changes in the climatic conditions (moisture content) to which the wood is exposed. This is the main reason why wood swells and shrinks. It is also believed that the digestion of wood by enzymes initiates at the free hydroxyl sites - which is one of the principal reasons that wood is prone to decay.
Acetylation effectively changes the free hydroxyls within the wood into acetyl groups. This is done by reacting the wood with acetic anhydride, which comes from acetic acid (the main constituent part of vinegar).
When the free hydroxyl group is transformed to an acetyl group, the ability of the wood to absorb water is greatly reduced, rendering the wood more dimensionally stable and, because it is no longer digestible, extremely durable.
Acetyl groups are already naturally present in all wood species as well as in humans and other mammals. This means that the manufacturing process adds nothing to the wood that does not already naturally occur within it, resulting in an end product that does not add toxins to the environment.
The effect of altering the wood's chemical structure, as opposed to merely altering its chemical content, is essentially to create a new product that is modified right through the cross section. By contrast, other comparable treatments merely insert chemicals (such as oils, ammonia or metal compounds) into the wood, improving durability but not dimensional stability.
Applications just got interesting...
The potential applications for MEDITE TRICOYA EXTREME are far ranging and will inspire creativity and discovery, particularly in environments where humidity and weather are usually concerns. Given the design flexibility of MDF, it is now possible to imagine MEDITE TRICOYA EXTREME used virtually anywhere
