⚙️ Application
Key Use BPA-L is a product specifically designed to be used in combination with the BPA nucleant agent for promoting adhesion between the chemicals in powder and the polyamide pellet surface.
Performance It enhances the mould release efficiency without formation of any plate out on the mold or surface aesthetical defects.
Result The pellet surface treated with the BPA-L and tumble mixed with the BPA behaves as a standard pellet, completely dry and dust free, suitable for any injection molding process.
❓ Frequently Asked Questions
Q
What is BPA-L and what is it primarily used for?
BPA-L is a strong mould release agent specifically formulated for polyamide (PA). It is designed to work in combination with the BPA nucleant agent to promote adhesion between chemical powders and the polyamide pellet surface, while significantly enhancing mould release efficiency.
Q
What is the recommended usage level of BPA-L on polyamide?
The recommended usage level of BPA-L is between 0.10% and 0.15% applied directly onto the polyamide (PA) pellets. This dosage range ensures optimal performance without negatively affecting the material properties.
Q
What are the physical properties and form of BPA-L?
BPA-L is a transparent pale yellow liquid with a melting point of 4°C and a cloud point at -20°C. Its liquid form makes it easy to apply uniformly onto pellet surfaces during the tumble mixing process.
Q
Does BPA-L cause any plate-out or surface defects on the mold?
No. One of the key performance benefits of BPA-L is that it enhances mould release efficiency without causing plate-out on the mold or any surface aesthetical defects on the finished part. This makes it a clean and reliable solution for precision injection molding.
Q
Is BPA-L compatible with standard injection molding processes?
Yes. Pellets treated with BPA-L and tumble mixed with BPA behave like standard pellets — they are completely dry and dust free, making them fully suitable for any conventional injection molding process without requiring special equipment or process modifications.
Q
How should BPA-L be used together with the BPA nucleant agent?
BPA-L should first be applied onto the polyamide pellet surface at the recommended dosage of 0.10%–0.15%, and then the pellets should be tumble mixed with the BPA nucleant agent. This combination ensures uniform distribution of the nucleant on the pellet surface while maintaining the dry, free-flowing nature of the treated pellets.
