Commentary

Similar characteristics to polycarbonate, it does not use bisphenolA,yet retains a moderate level of heat resistance, chemical resistance, and hydrolysis resistance

Key points

Although it is a transparent plastic, it has excellent impact resistance and chemical resistance.

Can be used in cases where PC(polycarbonate) would crack cause solvent.

Even with its thick wall, it has glass-like transparency and is often used for food containers.

Glass Alternative Tableware

Reason for adoption

Glass-like transparency (high light transmittance, low haze), lightweight (low specific gravity), resistant to breakage even if dropped (impact resistance), dishwasher-safe (heat resistance, chemical resistance)

Tableware

Reason for adoption

Does not crack even if dropped (impact resistance), does not change shape (dimensional stability), thick-wall moldability

Three-way stopcock (medical supplies)

Reason for adoption

Does not crack even under continuous stress during use (toughness and chemical resistance), BPA-free, solvent adhesion possible
