Br├╝ggemann at K2019: New heat stabilizers overcome performance limits of polyamides

BRUGGOLEN® TP-H1607 outperforms conventional copper salt based stabilizers. It extends mechanical property retention after heat aging to new limits.
┬ę Br├╝ggemann BRUGGOLEN┬« TP-H1805 is a high temperature stabilizer which enables glass fiber reinforced PA6 to be used continuously up to 200┬░C and PA6.6 beyond 200┬░C.

Heilbronn and D├╝sseldorf, Germany, October 16, 2019 ÔÇô BRUGGOLEN┬« TP-H1607 and BRUGGOLEN┬« TP-H1805 are additions to Br├╝ggemann's extensive additive portfolio for polyamides. These newly developed antioxidant blends allow polyamide materials to exceed current performance limits and offer exciting opportunities for the compounding industry.

BRUGGOLEN® TP-H1607 is a proprietary copper based stabilizer package which significantly extends long term mechanical property retention of polyamides to limits unmatched by existing classic copper salt based anti-oxidants. For example, tests demonstrate that BRUGGOLEN® TP-H1607 enables heat stabilization of unreinforced PA 6.6 beyond 5000 hours at 150°C, significantly outperforming conventional copper salt based stabilizers which level off at 3000 hours at this temperature. The extraordinary efficiency of BRUGGOLEN® TP-H1607 offers the opportunity to dramatically reduce copper and halogen content. In PA6.6 at 150°C the copper concentration in the compound was reduced by a factor of more than 5 and still matched the maximum performance level of existing copper salt based products. This capability allows cost savings and opens applications in the E&E sector, such as switch housings and sensors, where a comparative tracking index CTI of 600V is required. Significantly, trials revealed that BRUGGOLEN® TP-H1607 exhibits no greater influence on electro-corrosion than conventional phenolic/phosphite stabilisers used extensively in E&E.

With the new BRUGGOLEN┬« TP-H1805 Br├╝ggemann has developed an easily processable high heat stabilizer package which stretches the limit for continuous-use temperatures - up to 200┬░C in the case of glass reinforced PA6 and beyond 200┬░C for PA6.6. BRUGGOLEN┬« TP-H1805 does not require prior activation and is also effective at temperatures below 200┬░C. Thus, compounders have the opportunity to produce cost efficient aliphatic polyamide based materials for border line applications previously reserved for higher priced polyphthalamides or other high performance polymers such as polyphenylene sulfide. In addition, BRUGGOLEN┬« TP-H1805 may offer the opportunity to substitute, in certain applications, PA6.6 for the less expensive PA6.  Both stabilizers are supplied in pellet form and are easy to dose and disperse during compounding.
