Moisture resistant / Easy to print
PET-G (Polyethylene terephthalate glycol-modified) is a polyester thermoplastic characterised by a good balance of tensile strength and elongation at break. Its high resistance to water and chemicals makes it the material of choice for water-tight containers and protective cases.
PET-G is a versatile technical material, as easy to print as PLA, but with an improved balance of mechanical, chemical and thermal properties.
Applications
• Parts in contact with salts, acids and alkalis
• Functional prototypes and mechanical parts
• Waterproof applications
• Structural parts subject to mild stress
• Snap-fit joints
• Commonly used in beverage bottles
Properties
• Resistance to corrosive chemicals
• Good balance of strength, impact resistance and elongation at break
• Great dimensional stability and toughness
• Good glossy surface quality
• Good abrasion resistance
• Water and moisture barrier
• Withstand operating temperatures up to 70°C
• Low rate of ultrafine particles (UFP) and volatile organic compounds (VOC)
• Compatible with PVA supports
Technical information
Good balance of strength and ductility
PET-G parts are as strong as those made with PLA but offer a better mechanical profile. PET-G is not brittle, which means that it will not snap abruptly if pulled or bended, on the contrary, it will progressively bend and stretch until reaching it maximum elongation limit of 23%.
Resistant to chemicals and humidity
PET-G is highly resistant to chemicals and humidity, which allows for disinfection and cleaning without losing its mechanical properties to hydroalcoholic solutions.
