PTE compounds are made exclusively from high quality raw materials that are sourced from selected and certified suppliers. Our pool of raw materials currently consists of about 1300 materials. All customary polymers such as NR, EPDM, SBR, NBR, NBR/PVC, HNBR, BR, IR, CR, ACM, AEM, CSM and ECO are processed, along with fluorine and silicon. A highly trained team that covers the purchasing, laboratory-related and technology areas ensures that the specifications and PTE’s in-house quality standards are adhered to. Only in such a manner can it be ensured that the stringent requirements for compounds are fulfilled right from the beginning.
