Mechanical properties of the cross-linked PS-filled SBR, NBR, and NR nanocomposites.

Samples	Shore A Hardness	Stress at 100% Elongation/MPa	Stress at 300% Elongation/MPa	Tensile Strength/MPa	Elongation at Break/%	Permanent Set/%	Tear Strength/KN/m
Pure SBR	48	1.1	1.5	2.0	461	4	11
PS (30)/SBR	81	2.7	4.8	12.9	601	36	39
Pure NBR	55	1.2	2.2	3.5	438	0	16
PS(30)/NBR	80	2.7	7.6	9.3	345	12	33
Pure NR	35	0.7	1.6	28.3	801	16	30
PS(30)/NR	75	1.9	3.9	19.7	650	56	76

Note that filler loading was 30 phr, all samples were cured with sulfur.
