Sealing material

SBR

Styrene-Butadiene Rubber — low-cost, abrasion-resistant general-purpose rubber for non-oil, indoor service.

An economical general-purpose rubber with good abrasion resistance — for water and mild, non-petroleum, enclosed service.

Service temp -40°F to +212°F (-40°C to +100°C)

Overview

What SBR is best at

SBR is an economical general-purpose elastomer with good abrasion resistance and mechanical properties similar to natural rubber. It handles water and mild non-petroleum fluids well in wear-driven applications, but is unsuitable for oil, fuel, ozone or outdoor exposure — confining it to enclosed, cost-sensitive uses.

Where it's used

Typical applications by industry

Automotive

Brake components in non-petroleum fluids, bushings, vibration pads.

Industrial

General gaskets, non-oil seals, skirt board and conveyor components.

Material Handling

Wear pads, bumpers and abrasion-facing parts.

Choose SBR when

  • Cost-driven, abrasion-resistant parts in water or non-oil, indoor service
  • A natural-rubber-like profile with consistent heat/abrasion behavior

Consider an alternative when

  • Any oil, fuel, ozone or outdoor exposure → NBR, neoprene or EPDM
  • Elevated temperature → EPDM or FKM
