Styrene-Butadiene Rubber Gaskets

SBR (Styrene Butadiene Rubber) is known for its exceptional resistance to abrasion and its extraordinary tensile strength that makes it

very long lasting. This polymer is better than natural rubber when it comes to ageing and temperature resistance. SBR also has excellent

mechanical properties and is often used for coating rubber sheets

Besides the good insulation and shock absorption qualities they provide, SBR sheets can also resist inorganic chemical products, tearing

and the ozone. These sheets are ideal for automotive and construction industries

SBR Rubber can be compounded to provide very fine abrasion, wear, and tensile qualities. SBR can be readily substituted for natural

rubber in many applications with significant cost savings. Resilience is about the same as natural rubber 

Advantages

• More resistant to ageing and temperature than Natural Rubber

• Good resistance to abrasion, wear, and tensile strength

• Good resistance to many inorganic chemical products

• Excellent mechanical properties, low compression set

• High resilience like as natural rubber

• Limited resistance to mineral oils

• Cost saving than natural rubber

• Excel in cold & heat resistance

• Durable and long time usage 

 

Application

• Mining industry, industrial enviroments where is high abrasion

• Automotive and construction industries 

• Gasket material for hot or cold water  

• Aggregate processing industries  

• Skirting grades and scrapers   

• Cut for sealing strips  

• General packing  

• Tile industries 

• Buffer., etc
