Lignostone® M X/2-E3-HQ
Laminated Densified Wood
Lignostone® - laminated densified wood directly from the inventor. Consisting of veneers of the common beech (Fagus sylvatica) bonded using curable synthetic resins in conjunction with pressure and heat. More than 100 years of experience. For exceptional and scientifically proven mechanical and isolating properties.
- withstands high mechanical loading
- good electrical insulation
- low thermal conductivity
- low- and high-temperature resistance
- resistance to abrasion and wear
- low coefficient of sliding friction
- low specific weight
- very good oil absorption
Veneer quality
- SQ = Standard quality - Fulfills the requirements of IEC 61061
- HQ = High Quality - Surpasses the requirements of IEC 61061
- TQ = Top Quality - Surpasses by far the requirements of IEC 61061
Key to identification
The required grade for a specific application is defined by
Densification symbols
M = 1.10 to 1.25 g/cm³
Lamination
I= parallel
II= crosswise
X= tangential
Veneer thickness
1 = veneers < 2 mm
2 = veneers ≥ 2 mm
Type of resin
without character = mechanical types
E3 = electrical types
ring
Characteristics
- High mechanical strength at medium density
- High red beech veneer quality; tangential stacked
- Laminated densified wood T4R according to the standard IEC 61061
