STARTING POINT RUBBER COMPOUNDING …

1 STARTING POINT RUBBER COMPOUNDING FORMULATIONS. Important Note: These are STARTING POINT RUBBER COMPOUNDING Formulations for providing guide lines only and should be confirmed by laboratory trials. It is expected that modifications may be necessary to produce satisfactory commercial products. 1. Truck Tyre Formulations (Bias Ply).
