Materials

To choose the right type of rubber compound one of the most important issues is exchange of information between the recipient, producer and supplier of materials. The recipient is obliged to provide detailed data on chemical, mechanical and thermodynamical parameters of the final product. In a situation where MESGUM is not provided with the above mentioned information, most important is letting us know what is the main purpose of the product together with detailed description of the scope of work.

MESGUM has a wide range of renowned suppliers, which meet our consumer’s demands. Compounds processed by our company have a certification and are in accords with the REACH and ROHS declarations.

The above table shows approximate parameters of the materials used to produce rubber elements. Specific material demands are determined based on ISO, ASTM, DIN and EN norms. In case of doubts MESGUM, together with our suppliers, will help you choose the right type of material, which will be adjusted specifically to your needs or will come up with individual formula to achieve best results.

On client’s request we carry out additional tests such as: flammability test, permanent deformation on final product, etc.
