The different types and products related to high moisture resistant Particle board can generally be known by a green coloration of the base of the board, visible towards the steep edges. Every individual can identify the pack by its cover featured by a vertical green stripe, approximately 50 mm wide, down the right hand edge of each pack, on the same face as the label. Wood particles in these products are coated with a resin, formed into a mat and contrived to cure the resin and develop the proper amount of thickness which is essential for the product. It is, however, the resin used that bifurcates these Particleboards from Standard Particleboard. Unlike these products Standard Particleboards use a melamine urea formaldehyde (MUF) resin (plus other additives), with a pretty high amount of melamine content. Because resin cures to a clear film, similar to UF resin, a green dye is added to the resin mixture for the core flakes, to enable these Particleboard are high quality and better optimized than the Standard Particleboard. High moisture resistant particle board contrived and developed from different types of moisture resistant resins (such as phenol formaldehyde, tannin formaldehyde or co-condensates of these with urea formaldehyde) are usually dark brown in color and so it can be easily identified differently from the other bonded products. The green color quality and feature is only visible and applied if MUF resin is used. Wax emulsion is also considered as one of the pivotal process used in the resin system for MR Particleboard. Wax provides the product with resistance to the perforation of liquid water by offering water repellent advantages to board surfaces. The features of a high moisture resistant particle board are as follows.
Absorption and Swelling
Every high moisture resistant Particle board exhibits much more immunity and better response to wetting than the other cheap and common Standard Particleboard. While diameter swelling and residual swelling after the process of drying out are also much low in nature, the slow response rate is one of the main & practical advantages in negating the effects. Residual thickness swell should be absent to the naked eye unless the board is exposed to prolonged soaking.
Handling and Storage
Wherein most of these boards are defined to be moisture resistant in nature, there are a lot of possibility and chance of some swelling in thickness and change in dimensions if they are exposed to the swelling and soaking elements for protracted periods. Special care and precautions must be taken be to ensure that high moisture resistant particle board are not neglected in during the process of storage or on site delivery. Providers and interior professionals should keep in mind the same considerations and take the same precautions with MR Particleboard as they would for Standard particle board.
