FAQ:
Q: What makes SP-1516 suitable for camera lenses?
A: Its combination of high optical clarity (90% light transmission), low birefringence, and thermal stability prevents image distortion under varying temperatures.
Q: Can this material withstand soldering processes?
A: Yes, SP-1516's heat resistance (HDT 148°C) allows it to endure typical soldering temperatures without deformation.
Q: Is it compatible with coating processes?
A: The material offers excellent adhesion properties for common lens coatings including anti-reflective treatments.
Q: What molding parameters are recommended?
A: Optimal results are achieved with melt temperatures of 300-320°C and mold temperatures of 90-120°C, though specific parameters may vary.
Q: How does it compare to standard optical PC?
A: SP-1516 offers approximately 15% higher heat resistance while maintaining equivalent optical properties to standard optical-grade PC resins.
Q: Are custom formulations available?
A: While SP-1516 is a standard grade, we can explore custom solutions based on specific technical requirements.
