The weakest point of any rubber conveyor belt is the splice joint. If the splice joint is not sufficiently strong and durable then failure can be catastrophic. To get the best operational results it is essential that the splicing material rubber has very similar physical properties and characteristics compared to the rubber used to make the belt itself including the outer cover rubber and the skim (inter-ply) rubber. This is because each rubber-based component has very specific properties applicable to its function. The splicing materials must also be a compatible match to bond with each other. This is vital in order to ensure that the most efficient bond possible with good adhesions on both carcass and the transition to the base belt is created. These objectives are usually best achieved by using splicing materials supplied by the original manufacturer of the belt.
In order to help our customers achieve the strongest, most reliable splice joints, we supply a wide range of high-performance splicing materials and splicing kits. A virtually unique feature of the Dunlop range is that it has been developed by the same engineers and technicians who developed the conveyor belts they are designed to be used on. This means that Dunlop splicing materials and kits are as close to the perfect match as it is possible to achieve. The result is optimum performance in terms of adhesion, dynamic life and efficient application.
The Dunlop range of splicing materials
Hot vulcanization solution provides the best possible tack characteristics during the assembly of the splice and excellent adhesion levels in combination with Dunlofol.
Uncured inter-ply rubber is designed for use on the ‘steps’ of the splice to rebuild the belt carcass.
Uncured cover rubber is for use on the top and bottom of the splice to rebuild the belt’s cover area.
Uncured rubberised fabrics
Can be provided for use as reinforcements in heavy-duty/high tensile splices, for making ‘spot repairs’ and for speciality splices such as UsFlex finger splices.
Enerkol Cold Glue & Hardener Cement
For cold splicing of conveyor belts with textile carcass suitable for abrasion-resistant rubber covers. Enerkol is also a highly effective bonding glue for pulley lagging*.
(* For this purpose we advise that a special steel primer is used.)
Dunlop Splicing kits
Dunlop supplies full splicing kits containing everything necessary to create strong and durable splice joints for a wide range of cover qualities including abrasion, heat, fire and oil resistant versions and different belt types such as UsFlex and Ferroflex. The range also includes standard and pre-formed splicing kits for steel cord belting. All splicing materials and kits can be ordered in bulk quantities.
Dunlop – The safest splicing materials
Nobody in our industry works so physically close to rubber conveyor belts than splicing technicians. Yet another virtually unique advantage of using Dunlop splicing materials is that they are compliant with REACH (Registration, Evaluation and Authorisation of Chemical substances) regulation EC 1907/2006.
These regulations stipulate that all European manufacturers are legally obliged to comply with the regulations relating to chemicals, preparations (mixtures) and substances used to create finished products. The European Chemicals Agency (ECHA) based in Helsinki is the central point in the REACH system. At Dunlop, we see REACH compliance as a vital consideration for anyone responsible for the welfare of those who use splicing materials as part of their daily function.
