Frequently Asked Questions
Q
What is BPA and what is it used for in polyamide compounding?
BPA is a white powder additive used in polyamide (PA) compounding. It dramatically affects the crystallization rate of polyamide compounds and provides efficient mould release, making it a key processing aid in PA6 and PA66 applications.
Q
What is the recommended usage level of BPA in PA66 and PA6?
The recommended usage level is 0.15–0.20% in PA66 and 0.30–0.50% in PA6. These dosage ranges are optimized to deliver effective mould release and cycle time improvements without negatively affecting the base polymer properties.
Q
What is the melting point of BPA, and does it suit high-temperature processing?
BPA has a melting point range of 160–180°C. This makes it well-suited for high-temperature polyamide processing environments, ensuring it activates and disperses effectively during compounding without premature degradation.
Q
How does BPA improve the dimensional stability of moulded parts?
By influencing the crystallization rate of the polyamide matrix, BPA helps achieve a more uniform and controlled solidification process. This leads to improved dimensional stability in both injection-moulded and extruded articles, reducing warpage and shrinkage inconsistencies.
Q
What active concentration range does BPA offer?
BPA is available with an active concentration range of 30–100%, providing flexibility for formulators to select the appropriate grade based on their specific compounding requirements and target performance outcomes.
Q
Can BPA help reduce cycle times in polyamide injection moulding?
Yes. One of the key benefits of BPA is its ability to shorten cycle times in polyamide injection moulding. By accelerating the crystallization rate and improving mould release, BPA enables faster demoulding and higher throughput in production environments.
