My company formulates a structural adhesive and has been using one source to supply our polymeric and monomeric diphenylmethane diisocyanates and polyether polyols. We are considering qualifying a second source for these raw materials. What should we be aware of before taking such a step?
It makes a good deal of business sense to have multiple suppliers for your key raw materials. Confirming competitive pricing and product availability is a relatively straightforward process, but becoming comfortable with essential technical and performance requirements can be more complicated.
