Polypeptideamide resin (PPA) outperforms standard polyamides with higher strength and stiffness at high temperatures, better retention of properties in wet environments, and higher resistance to a wider range of chemicals tolerance.
With a heat deflection temperature of 280°C (536°F) and a continuous operating temperature of 210°C (410°F), Amodel? PPA (polypeptide amide resin) can withstand the high temperatures of under-hood applications, which It is unbearable for traditional nylon and other polymers.
Amodel PPA A-8940 HS Highly reflective polymer for LED surface mount packaging
Specially formulated highly reflective white Amodel Polypeptide Amide Resin (PPA) grades provide long life for high brightness LED products.
Proprietary formulations add exceptional stability to a family of polymers with the highest thermal performance ideal for today’s more demanding products. Further improved processing performance enables manufacturers to meet the extremely demanding productivity requirements of complex, multi-cavity molding.
Amodel PPA A-8940 HS Main Features
High initial brightness
Maintain illumination
Can withstand SMT up to 310°C
High flow rate for low profile LEDs
Epoxy resin and silicone resin encapsulation, with excellent adhesion
Amodel PPA Electronic Components
In high temperature resistant electronic applications, such as microphones, satellite receivers, micro switches, connectors, camera modules and LEDs, Amodel? PPA outperforms ordinary polyamides. Excellent electrical performance and high temperature resistance make Amodel PPA suitable for electronic components exposed to SMT processing environment.
