Density (dry weight) = 31-37 lbs/cu. ft. Density (dry weight) = 38-45 lbs/cu. ft. Modulus of Elasticity (stiffness) = very low Density (dry weight) = 46-52 lbs/cu. ft. Work to Maximum Load = very low Shrinkage, Tangential = moderate Shrinkage, Radial = very small Max. crushing strength = low Hardness (side grain) = very soft Density (dry weight) = 23-30 lbs/cu. ft. Bending strength (MOR) = low Toughness-Hammer drop (Impact Strength) = very low Toughness-Hammer drop (Impact Strength) = low Toughness (total work) = very low Toughness (total work) = low Shrinkage, Tangential = small Shrinkage, Radial = small Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = low
