【Test method】
Hardness: JIS-K-6253
100% modulus, Tensile Strength, Elongation: JIS-K-6251
Tear strength: JIS-K-6252
Abrasion resistance: JIS-K-6264 (Load: 10 lb).
The smaller the value is, the better abrasion resistance it has.
Strain recovery: Katsura’sset test
The bigger the value is, the better strain recovery property it has.
Metal cylinder (OD: 5mm) is pressed onto the rubber sample to apply 2mm dent. Recovery rate is measured after 3 minutes after metal cylinder is removed (Moving speed 2mm/min.)
