What is the physical and chemical properties of PETG?

Injection molding process conditions

Drying treatment: Drying treatment before processing is required. Humidity must be below 0.04%. The recommended drying conditions are: 65°C, 4h, and the drying temperature should not exceed 66°C

Melting temperature: 220~290℃

Mold temperature: 10~30℃, recommended 15℃ Injection pressure: 30~130MPa

Injection speed: Higher injection speeds can be used without causing embrittlement

Chemical and Physical Properties

PETG is a transparent non-crystalline material. The glass transition temperature is 88°C. The allowable range of injection molding process conditions of PETG is wider than that of PET, and has the comprehensive characteristics of transparency, high strength and high toughness.
