About BYK – Copper Salt Heat Stabilizers
BYK Chemical's copper salt heat stabilizers BYK-MAX HS 4300, 4304, 4306 and other products are in a leading position in the market. They are originally produced in the United States and Europe and are imported with original packaging. This type of heat stabilizer product does not contain resin and is 100% active. Processing at room temperature can fully maintain the efficacy of the additive and provide high accuracy and precision for the formulation. It can be dispersed using general processing equipment. It has a complete quality management system. A single particle formula can replace masterbatch or multiple single-component formulas. And customized formulation services can be provided according to customer needs.
Introduction and chemical mechanism of nylon copper salt (long-term) heat stabilizer
The addition of heat stabilizers and antioxidants to plastics is to ensure that the properties of the plastics remain stable during processing and use, and will not change color, deteriorate, or deteriorate in performance. Under the operating temperature range of plastics, the recommended heat stabilizers are:
BYK-MAX HS 4300, 4304, 4306 product series can provide very effective protection for nylon during the heat aging process, helping to increase the working temperature of non-filled nylon to 90-120℃, and the working temperature of glass fiber-added nylon to 150℃. High-temperature nylon can withstand high temperatures of more than 180℃ and is expected to meet the continuous use time of more than 400 hours. The recommended addition amount is 0.1%-1%.
Mainly used in glass fiber reinforced or non-reinforced PA6, PA66, PA46, PA9T and other PA copolymers to maintain the excellent performance of nylon under high temperature conditions :
Excellent high temperature thermal stability, suitable for the most demanding application environments.
The tensile properties are good at 150°C for 2000 hours (PA6) and 180°C for 500 hours (GF PPA).
Excellent processing performance, the processing aids contained can improve the processing performance during extrusion and injection molding.
High cost performance.
BYK copper salt heat stabilizer mechanism of action:
Thermal oxidation of polyamides: degradation and stabilization
Stabilization mechanism of copper salt system:
Potassium iodide (KI) reduces copper to +1 copper and is therefore consumed. Potassium bromide (KBr) can also be used as a stabilizer, and a large amount of stabilizer can improve long-term thermal stability (LTTS).

Q : Can copper salt heat stabilizers be used in other resin systems? Is it necessary to add antioxidants when adding BYK copper salt heat stabilizers to polyamide?
Answer : BYK copper salt heat stabilizer products can only demonstrate excellent performance in nylon systems. They can play a role in processing heat stabilization during screw extrusion, replace phosphite stabilizers, and have extremely high synergistic effects with other plastic additives 1098 (including UV absorbers, hindered amine stabilizers, other stabilizers, etc.).
Q : How much nylon should be added to achieve long-term thermal stability?
A : BYK copper salt heat stabilizer products use traditional extrusion modification technology and are easily dispersed in polyamide. Usually, the addition amount is about 0.24%. Under the condition of 150°C, the tensile properties pass the 2000h heat resistance test (PA6) and maintain 500 hours at 180°C (GF PPA). If you want to achieve better long-term thermal stability in high temperature environment, the best addition amount needs to be determined through a series of tests, and the maximum concentration can be added to 1%.
