Triangle resolution method first see its elasticity is flexibility. Good elasticity high hardness of wearability; Look at the appearance, clear cloth; Can also use the hand holding the triangle to loosen the feel is not sticky, these are really achieve quality is achieved. Triangle with special structure and cable structure with core two kinds, respectively by the package cloth, the top rubber and bottom rubber, tensile body of four parts. Rope core structure of the triangle, easy fabrication, tensile strength, low cost, wide application of special belt core structure of the triangle, good toughness, high strength, suitable for high speed occasion.
