Commentary

Using the manufacturing technology for PC homopolymer as a base, PC is copolymerized with other monomers to give it various functions and unique properties that were not available in PC homopolymer. *The structural formula, properties, and examples of use introduced in this section are examples of "PC and siloxane copolymers."

Key points

A copolymer that has been copolymerized with siloxane to give it excellent impact resistance, chemical resistance, and mold releasability in low-temperature environments.

A copolymer that has been copolymerized with a biomonomer derived from castor oil to improve flowability without lowering the molecular weight (maintaining impact resistance).

Other copolymers that have been copolymerized with special monomers include copolymers that have improved surface hardness, copolymers that have improved heat resistance while maintaining high transparency

And copolymers that reduce the generation of smoke and toxic gases when burned.

Medical device housing

Reason for adoption

Does not crack easily and endure repeated disinfection (impact resitance, chemical resistance)

Smartphone Housings

Reason for adoption

Does not crack even if dropped (impact resistance), does not discolor easily without painting (weather resistance), and does not crack when exposed to chemicals such as cosmetics (chemical resistance)

Photovoltaic (1.5kV) connector housing

Reason for adoption

Does not deteriorate outdoors, does not crack easily (weather resistance, low-temperature impact resistance), and does not burn easily (flame resistance)
