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.
The bonding of each single STRATO-STOCK® panel is regulated by ultrasonic machinery.
Laser screen printing
Afterwards, the panel is marked on the rear with a laser screen printing which guarantees traceability.
The panel can be easily traced thanks to a label showing the barcode and lot number.
Application of STRATO-STOCK® panel in the frame.
The impermeability of the product keeps the original mechanical characteristics of the wood stable over time, avoiding a rapid deterioration.

HIGH ABRASION RESISTANCE
The images demonstrate the performance of both STRATO-STOCK® and film faced plywood subjected to both a scratch and taber stress test. STRATO-STOCK® panels do not fear heavy abuse.

The images show the nailability of the STRATO-STOCK® panel and the absence of splintering, which is common in phenolic film faced plywood.
EXCELLENT RESISTANCE TO CHEMICAL AGENTS
Thanks to its polypropylene based surface, the panel resists cement alkalis and other corroding agents.
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).
