Specialty tags

Screening hints only. Certifications (medical, food-contact, flame, HazLoc) apply to specific grades and finished equipment — verify with supplier documentation.

Electrical insulating. Commonly used as electrical insulation — dielectric performance is grade- and condition-dependent.
Flame-retardant grades. FR formulations exist for many polymers — UL/IEC ratings apply to the finished grade and geometry.

Advantages

Good dimensional stability in many grades
Useful electrical and heat performance for connectors
Often glass-filled for stiffness

Limitations

Moisture/conditioning considerations for some grades
Chemical compatibility must be checked
Higher cost than commodity plastics

Compatible Processes
