BoL - these are the cautions that we would advise:

In some circumstances, it can be necessary to carry out a splice on a belt, using materials other than from the parent belt manufacturer.

For standard grades, like DIN X/Y/W - based on natural rubber, SBR, BR, there is a reasonable expectation that similar basic "chemistry" would be employed and consequently a similar expectation of adequate compatibility when the splicing materials are used correctly, as intended by the manufacturer.

With "special" grades, FRAS, oil or heat resistant, there is a likelihood of incompatibility and the correct materials must be used. Different polymers and different curing and bonding systems can be used, which may be incompatible.

Where other materials are being used there are two important considerations:

Notwithstanding the above remarks, the belt manufacturer cannot guarantee the compatibility of the materials being used and it is the care of the provider or manufacturer of the materials to provide any assurance or guarantee that may be required.

and..

The cure rate of materials may differ considerably and a curing chart or specific time/temperature conditions must be supplied by the provider or manufacturer of the materials being used.

cheers,
