Application
|
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.
As further performance, it enhances the mould release efficiency without formation of any plate out on the mold or surface aesthetical defects. 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 primarily used in combination with the BPA nucleant agent to promote adhesion between chemical powders and the polyamide pellet surface, while enhancing overall 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% onto the PA (polyamide). Staying within this range ensures optimal mould release performance without compromising pellet quality.
Q
Does BPA-L cause any plate-out or surface defects on the mold?
No. BPA-L is specifically designed to enhance mould release efficiency without causing any plate-out formation on the mold or any surface aesthetical defects on the finished part.
Q
Is BPA-L compatible with standard injection molding processes?
Yes. Pellets treated with BPA-L and tumble-mixed with BPA behave as standard pellets — completely dry and dust free — making them fully suitable for any injection molding process without requiring special handling or equipment adjustments.
Q
What is the physical form and appearance 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, making it easy to handle and apply uniformly onto polyamide pellet surfaces.
Q
How should BPA-L be used together with the BPA nucleant agent?
BPA-L should first be applied to the pellet surface at the recommended dosage level (0.10%–0.15%), and then the treated pellets are tumble-mixed with the BPA nucleant agent. This combination ensures even distribution of the chemicals on the pellet surface and maximizes both nucleation and mould release performance.
