Blair Rubber’s cover stock and tie gum materials are engineered to create strong, durable vulcanized conveyor belt splices while matching the performance characteristics of the original belt. Available in a variety of rubber compounds for different belt constructions and operating environments, these uncured materials help ensure optimal adhesion, splice integrity, and long service life.
Grade B belt stock is an uncured black, soft, carbon-black-reinforced 100% chlorobutyl rubber. It is intended for use as a tie gum and cover stock when splicing 100% chlorobutyl-covered conveyor belts. Also intended for use as a tie gum for EPDM covered conveyor belts.
Grade BNI belt stock is an uncured black, soft carbon-black-reinforced 100% nitrile rubber intended for use as a tie gum and cover stock when splicing nitrile-covered conveyor belts.
Grade EP belt stock is an uncured black, soft carbon-black-reinforced 100% EPDM rubber intended for use as a cover stock when splicing EPDM-covered conveyor belts.
Grade GB belt stock is an uncured black, soft carbon-black-reinforced 100% natural rubber intended for use as a cover stock when splicing gypsum board conveyor belts.
Grade H belt stock is an uncured black, soft carbon-black-reinforced 100% SBR rubber intended for use as a tie gum and cover stock when splicing 100% SBR-covered conveyor belts.
Grade HiT belt stock is an uncured black, soft carbon-black-reinforced 100% natural rubber intended for use as a tie gum when splicing RMA Grade I, Grade II, and gypsum board conveyor belts.
Grade S Belt Stock is an uncured black, soft carbon-black-reinforced 100% polychloroprene (Neoprene™) rubber intended for use as a tie gum and cover stock when splicing polychloroprene- based conveyor belts. The Blair Rubber Grade S splice kit has been approved by MSHA for use in underground mining. It meets the quality assurance requirements of MSHA CS-11 under 30CFR14.8.
