a new heat stabilizer masterbatch for aliphatic nylons is said to provide longer product life at elevated temperatures. bruggolen of brüggemann
tp-h1804 is specifically designed for use in continuous operating temperatures between 320°f to 374°f. it is to bruggolen
complementary to tp-h1805, which stabilizes reinforced nylon at temperatures above 392°f. supplied in granular form, this concentrated additive can be dosed very precisely and is therefore highly targeted.
according to the company, a “best-in-class” bruggolen
tp-h1804 is significantly better than previous copper salt stabilizers in maintaining mechanical properties. for example, after adding 5% glass fiber reinforced nylon 66, after 5000 hours of heat aging at 374 ° f, its tensile strength still exceeds 50% of the initial value; this limit cannot be reached. at 338°f, even a 2.4% addition was sufficient to exceed the 5,000-hour mark due to the additive’s excellent efficiency. therefore, bruggolen
as an anti-aging additive, tp-h1804 can maintain the service life of molded parts under expected thermal load through its flexible compounding ability.
