- Laser Cutting - Interior Birch Plywood
An ultimate in performance and durability

is a specially developed Birch Plywood with colourless synthetic resin adhesive for laser cutting, foundry pattern applications and is commonly used as die cutting plates.. It is equally suitable for several indoor uses and for interior applications in dry areas. The excellent strength properties of the panel enable die tools to be fabricated with accuracy in dimensions. The absence of any voids or gaps or open dead knots in intermediary layers and fortified bonding controls moisture movement as well as combustion gases emissions during laser cutting operations.

Effect of humidity and moisture

• Wood veneer is a living material and is subject to moisture movement according to surrounding conditions, which affects the flatness of panels. It is important to condition the panels to reach a moisture content near to the equilibrium of their permanent environment.
  
  
• Like other wood-based panel products, Birch Plywood is also hygroscopic and its dimensions change in response to a change in humidity. A change of 1% in moisture content typically increases or decreases the length, width and thickness by 1% in dimensions and thickness. It is therefore desired that the edges are sealed with a suitable acrylic paint to prevent and/or control ingress of moisture and humidity and consequent swell in thickness and expansion in dimensions.

Technical Specification

Preservatives

Plywood is made from natural Birch wood Veneers grown and harvested in Russia and is free from any toxic chemicals except resin. As is common knowledge, all wood products are susceptible to insects or termites and/or borers present in different climatic zones in the soil or buildings. It is recommended that the users are applying the coat of suitable chemicals or insecticides on all exposed surfaces of wood in addition to treatment of masonry foundations of the building where the Wood products are required to be use. Fipronil emulsified concentrate at about 3% is one such chemical and effective deterrent against insects and pests or termites in tropical climate zones. However, the application should be in accordance with manufacturers guidelines for effective results. Users own discretion in selection of appropriate chemical and its doses or frequency of such treatment is advised for satisfactory results in the light of experience gained over the period of time.
