 note = {Polyvinylchloride floor materials were made using magnetic separated shirasu (one kind of soil from an eruption, which exists abundantly in Kagoshima-ken) as fillers. 
These materials which using the shirasu as fillers were better on tensile strength, resistance for abrasion and degree of water absorption than the materials which using calcium carbonate as fillers. 
The following were the physical characteristics of No. 28 sample (polyvinylchloride powder 100:shirasu filler 350:plasticizer 50:titanium oxide 10:inhibitor 3):tensile strength, 0.67Kg/mm^2; elongation, 
8.1%; Young's modulus, 51.2Kg/mm^2;  specific gravity, 1.89g/cm^3; hardness; 30g; degree of water absorption, 0.001g/100cm^2; resistance for abrasion, 0.002g/cm^2.},
