La description

Styrene-butadiene rubber transparency can also be used in the manufacture of soft parts, medical appliances, food containers, stationery and auto interior decoration parts. but the number of double bonds, activity is low, because of the existence of phenyl side and side of ethylene based space steric big, poor flexibility,
Physical and mechanical properties, good comprehensive performance. Mechanical properties, processing performance and product performance are similar to natural rubber. Is unsaturated rubber, the available sulfur vulcanization, because no saturation than natural rubber soles, slower vulcanization, the processing safety improved. Than NR vulcanizates has better abrasion resistance, aging resistance, permanent deformation (compression deformation is poorer at high hardness) and resistance to permeability, but elastic, cold resistance, tear resistance, particularly hot tear, flexible crack resistance is poor.Production in the world *5% of styrene-butadiene rubber used in tires
Processing performance: due to the molecular chain flexibility is poor, poor processing performance. When mixing performance, poor to wetting ability of chelating agent, high temperature, high load equipment; Pressure out of the difficult operation, semi-finished shrinkage or expansion rate. With NR, BR, etc. General rubber with good performance.
Heat resistance: 0 ° C ─ **0 ° C.
Does not recommend the use of strong acid ester, ozone, oil, oil and ester, and most of the hydrocarbons.
