Technical Parameter Of Bamboo flooring

Bamboo flooring Brief introduction

The bamboo flooring planks are machined with tongue and groove edges to provide interlocking assembly. The ends are also end-matched with tongue and groove. Each piece is machine sanded on top, with rough glue-ready surface on bottom. The edge above the tongue on the long edge is angled and ready to accept standard flooring nails.
Each pre-finished bamboo flooring is coated with a clear, UV cured acrylic polyurethane. State of the art machinery is used to apply and cure the durable coating.ABRASION RESISTANCE
Bamboo flooring tested according to ASTM C501 (H-22 Calibrated wheels loaded with 1000 gram weight at 70 RPM for 1000 cycles) weight loss = .349 grams = .012 ounces. The test we have done for abrasion resistance showed that BamPlank tm finish is one of the toughest to be found in the wood flooring industry. According to ASTM 4060 “Taber Abrasion Test”, it took over 4,000 cycles to remove the finish coating (United States Testing Company).

FLAMMABILITY
Bamboo flooring tested according to ASTM E648 Critical Radiant. Panel Test. Passes with a CLASS I rating per NFPA “Life Safety Code”. This means that bamboo can be used in all classes of buildings. (United States Testing Company).

SMOKE DENSITY
Bamboo flooring tested according to ASTM E622 pass = 450 or less, passes with 269, flaming mode and 329 non-flaming mode. Bamboo was found to have considerable lower smoking properties than the leading oak product (United States Testing Company).

Hardness
The hardness of our bamboo plank flooring was determined to be 35.4 MPA between the joints and 49.8 MPA at the joints (Materialab).

CHEMICAL AND STAIN RESISTANCE
Bamboo flooring tested with the following chemical reagents finish was
unaffected:
Acetic Acid (5%) Acetone Ammonium Hydroxide (10%) Toluene Detergent Solution Ethyl Alcohol (50%) Hydrochloric Acid (10%) Turpentine Heavy Duty (.025%) Hydrogen Peroxide (3%) Soap Solution (1%) Sodium Hydroxide (1%)

INDENTATION RESISTANCE
Bamboo flooring according to ASTM 1037 (Janka Ball Hardness) showed an
average hardness of 1640. (27% harder than northern red oak and 14% harder than hard maple)

DIMENSIONAL STABILITY
Bamboo flooring according to standard method for wood flooring showed a
dimensional change coefficient of .00144 . (50% more stable than red oak). Bamboo planks do not expand under high temperatures or high humidity conditions (Ortech Corporation).

Internal Bond Strength
The internal bond strength of bamboo was determined to be 2107 Newtons (Ortech Corporation).

Coefficient for Dry Conditions
The radial direction was tested to be 0.138 and the chord direction was 0.149 (Middle-Southern Woods University).

SLIP RESISTANCE
Bamboo flooring according to ASTM D2047 = results 0.71 coefficient of Friction. Static coefficient of 590 exceeds the OSHA recommendation for level surfaces in the workplace.

COMPRESSIVE STRENGTH
Bamboo flooring according to ASTM D3501-86 A = results A) Parallel to Grain= 7,549 PSI B) Perpendicular to Grain =2,566 PSI C) Flatwise = 16,925PSI at 50% Strain. (Load to compress to 1/2 thickness)

BENDING STRENGTH
Bamboo flooring tested according to ASTM D3043-87 result = 13,608 PSI
BENDING ELASTICITY MODULUS
943,443 PSI

SHEAR STRENGTH
Bamboo flooring tested according to BRITISH STANDARD # 373 result = Parallel to Grain 1365 PSI

TENSILE STRENGTH
Bamboo flooring tested according to ASTM D3500-90 A result = Parallel to Grain 15,290 PSI

Glue
Non-toxic, for formaldehyde release: formaldehyde emission attain E1 standard requirement.

Moisture
8-12%

Density
0.72g/cm3

IMPACT RESISTANCE
97.1 KJ/M2 Hardness:719kg/cm2, Grindability:110 rotations

These test results can also be found from some other bamboo flooring company, but their product not the same material, so the result maybe not quite same. If you are interested, we can offer some pieces of bamboo flooring samples for your test.
