Styrene-Butadiene Rubber (SBR)

Styrene-Butadiene Rubber (SBR) / 丁苯橡膠

The most widely synthetic rubber in the entire world is SBR, a copolymer of styrene and butadiene. For the most part SBR rubber is used in tire by blending with natural rubber and butadiene rubber. SBR is weak and unusable without reinforcement by carbon black, but with carbon black it is strong and abrasion–resistant. The defects of SBR are poor resistant to oil and not suitable in weathering, UV, oxygen & ozone because the double bond in the polymer backbone.

Service Temperature
The Service Temperature of SBR can be designed from -55 C to 100 C.

Hardness
50 to 70 Shore A are available

產品特性:

丁苯橡膠是丁二稀與苯乙烯之共聚合物,與天然膠比較,品質均勻,异物少,但機械強度則較弱,可與天然橡膠摻合使用。主要適用於輪胎業,膠布業及輸送帶行業等。
