RYNITE is a glass reinforced PET (Polyethylene Terephthalate), formulated so that the crystallization will rapidly be processed when injecting.
It is an excellent product when the molded parts need rigidity, dimensional stability, beautiful exteriors, high temperature characteristics,
solvent resistance, and electrical characteristics.

RYNITE Grades and Applications
Grades Characteristics Major Applications
General grade
Rynite 530 PET resin with 30% reinforced glass fiber / harmonized strength, rigidity, and impact resistance with excellent electrical characteristics, exteriors, and chemical resistance Electrical / electronic components such as ignition parts,
relay base, lamp socket, bobbin, pump housing, machinery components including gear / sprocket, vacuum cleaner, motor end bell, chair handles, and caster and furniture parts
Rynite 545 PET resin with 45% reinforced glass fiber / excellent strength, rigidity, and creep resistance Lamp housing, compressor housing, fuel/air temperature sensor housing, sunroof frame, spool, bobbin, transmission parts, medical tools
