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

Laser Cutting Interior Birch Plywood Laser Cutting Interior Birch Plywood Laser Cutting Interior Birch Plywood Laser Cutting Interior Birch Plywood Laser Cutting Interior Birch Plywood

Birchply™ Birch 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.

Key Benefits

  • Highly wear resistant
  • Resistant to most aggressive environments, including chemicals
  • Durable
  • Hard surface
  • Easy to work with using conventional woodworking tools and fasteners
  • Environmentally friendly

Resistance to temperature variation: through a range of -40°C to +50°C (-40°F to +122°F) and is available in a variety of thicknesses and sizes

Certifications

PEFC certified products are also available under the chain of custody programs on prior arrangement

Properties

  • Moisture resistant, dimensionally accurate & stable.
  • Strong and light
  • CNC Routable and can be machined,
  • Meets EUTR standards,
  • Meets European E1 formaldehyde emission requirements (EN 120:1992) and also California ARB regulation P2

Veneers

  • 100% natural whole piece or spliced Birch Veneers of 1.4mm thickness throughout the plywood without any gaps or open splits or joints.
  • Face veneer: Qualities B and/or BB as may be required.

Bonding

  • Cross-bonded interior gluing according to EN 314-2 (Plywood - Bonding) class 1 interior.

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.

  • The recommended stocking conditions are 20°C and a RH of air of about 60%.

It must not be exposed to wet or high humidity conditions!

Storage conditions:

  • The recommended stocking conditions are 20°C and a RH of air of about 60%.
