Exxon butyl rubbers’ unique combination of barrier properties, resistance to ozone, heat and chemical resistance, and flex and tear and abrasion resistance make them ideal for many industrial applications.
Exxon™ halobutyl rubber is used in conveyor belt applications that require resistance to heat and chemicals. These compounds are particularly well suited for belts conveying hot material or those that pass through ovens or other high-temperature zones.
The inherent resistance of halobutyl rubber to contact with water and normal concentrations of acids and bases is reinforced with the cure versatility of Exxon™ bromobutyl rubber . The low unsaturation, low permeability and low polarity of butyl rubber also impart very good resistance to a variety of chemicals.
Condenser packing for electrical appliances benefits from the low permeability (sealability of electrolyte of chemical condenser) and chemical inertness (no affect to and from electrolyte) associated with butyl rubber. The polyisobutylene polymer chain imparts barrier properties that minimize the transmission of air and water vapor and makes this polymer better than most rubbers at resisting degradation due to heat and in maintaining mechanical properties. Exxon butyl rubber has very good dielectric properties and is an excellent electrical insulator. It can be compounded for both conventional and heat-resistant applications.
