Know your Particle Boards

Print Friendly, PDF & Email

Particleboards are products of technology and technical configurations and are performance oriented. Several furniture manufacturers use huge volumes of particle boards to process in their factories and the biggest challenge is to know if the quality of the board which looks more or less the same externally, without knowing how it has been internally “tailored” by the manufacturer. Evaluate the boards on the below mentioned minimum values to embrace the best product available.

Particleboard is an engineered product capable to last a decade withstanding the daily abuse just like a plywood if right quality is used with the right Modulus of Rupture, Modulus of Elasticity and Internal bond properties.

As per EN 312, boards for furniture and internal fitments must be of Type P2.

Importance of Bending Strength and Internal Bond of particleboard: Bending strength and Internal Bond are the key engineered properties of the particleboard which reflect its superior strength and durability.

Door hinges getting loose: Holding hinges is a property of the construction of the board. If the board has a low internal bond the hinges loosen within short time and can cause the shutter to come loose from the carcass.

Warping of cabinet shelves: Sagging or warping by placement of any weight on the shelves is caused by the board having poor modulus of rupture. A poorly produced board can sag even by its own weight.

Swelling of particle board furniture: Swelling is a natural reaction to moisture for any wooden product. The resin formulations can inhibit swelling to less than 8% after two hours immersion. However compromise on the resin additives and formulations will cause the swelling.

What is Formaldehyde?

Formaldehyde is a common precursor to more complex compounds and materials. When treated with phenol, urea, or melamine, formaldehyde produces hard thermoset phenol formaldehyde resin, urea formaldehyde resin, and melamine resin. These polymers are common permanent adhesives used in plywood, Particleboards and MDF. Production of formaldehyde resins accounts for more than half of formaldehyde consumption.

Formaldehyde has been declared a known carcinogen chemical and for any indoor use the emission level is necessary to be below 8mg /100g oven dry board. The low emission ensures the air quality has no toxic emissions from the furniture items. In India unfortunately the awareness of the formaldehyde emissions is too low. In EU all engineered board manufacturers produce only E1 norm as standard minimal emission and other countries too have similar or lower emission like E0 level board mandatory.

Sleek Boards India LLP a leading marketing Company for Particleboards and MDF and related items offers HeveaBoard with:

• Low emission and high mechanical properties
