Processing Advantages

POLYLAC® PA-757’s processing characteristics enhance its suitability for these applications:

• Injection Molding Compatibility: Processed at melt temperatures of 220–250°C on standard injection-molding machines, ensuring smooth plasticating.
• Demolding Ease: Favorable surface slip properties allow draft angles of 0.5–1°, facilitating production of complex moldings.
• Surface Quality: High gloss achieved at mold temperatures of 60–80°C, ideal for visible components.
• Recycling Potential: Regrind can be reused if free from contamination, supporting sustainability.

Limitations

• UV Sensitivity: ABS is prone to yellowing and brittleness under prolonged UV exposure, making it unsuitable for unpainted exterior applications.
• Chemical Resistance: Offers moderate resistance but may require coatings for exposure to harsh chemicals like acids or alcohols.
• Material Compatibility: Incompatible with most thermoplastics (e.g., polyolefins, polyamides) in the melt, leading to delamination if mixed.
• Non-Food-Grade: Not typically certified for direct food contact, limiting its use in food-related applications.
