1. Description:
PC polycarbonate resin is an amorphous thermoplastic material with high-impact strength, high modulus of elasticity, and good dimensional stability. These properties, in addition to good electrical characteristics, make machine grade polycarbonate rods an excellent choice for electrical/electronic applications. Polycarbonate's strength, impact resistance and transparency also make it an ideal material for certain transparent structural applications.
Features of Machine Polycarbonate:
Excellent impact resistance.
Continuous use temperature to 290°F (145°C)
Good Transparence (clarify and tint varies by manufacturer and production techniques)
Tint can vary from grey to purple depending on polycarbonate resin used.
Good dielectric properties
Economical thermal performance
