CHARACTERISTICS

STRATO-STOCK® is a Birch plywood panel with plastic overlay.

  • Abrasion resistance is considerably higher
  • When nailed, the panel does not splinter
  • Cleanable with high pressure water
  • The panel’s life is at least four times longer than traditional phenolic plywood

The ILPA company was the first, in 1993, to patent and manufacture this new product for the concrete formwork industry. Subsequently, using specific “joint development programmes”, it patented and made further versions, such as the Xlife panel.

STRATO-STOCK® panel is compatible with all formwork systems available on the market.

MECHANICAL RESISTANCE

The impermeability of the product keeps the original mechanical characteristics of the wood stable over time, avoiding a rapid deterioration.

EXCELLENT RESISTANCE TO CHEMICAL AGENTS

Thanks to its polypropylene based surface, the panel resists cement alkalis and other corroding agents.

APPLICATIONS
RECYCLABLE

The STRATO-STOCK® panel consists of a birch plywood core overlaid with a polyolefin based plastic sheet. A study has shown that it is possible to re-use the STRATO-STOCK® panel at the end of its lifecycle. The panel, ground down with other materials, has been used as material to manufacture some products as shown below, injected with an open mold using Plastech technology (read more).
