Polyethylene Terephthalate Glycol (PETG)

Product Description

Extruded Polyethylene Terephthalate Glycol (PETG) is a high-impact, FDA-approved thermoplastic co-polyester that provides toughness, chemical resistance and fabricates well. Due to its low forming temperature, PETG is readily heat-bent and can also be easily bonded using solvents. PETG can also be treated with a UVA inhibitor for inside or outside use while remaining FDA compliant. Busada PETG tubing has been used to convey coffee beans, flour, grains, other foods, paper cups, and containers pneumatically and by chain conveyance.

PETG, like polycarbonate, is a thermoplastic or polymer that turns to liquid when heated and hardens to a very glassy state when cooled. PETG shares many characteristics with polycarbonate.  They are highly impact-resistant, possess excellent clarity, and feature high light transmission rates (90% for PETG and 88% for Polycarbonate).

The most compelling reason to consider PETG over polycarbonate tubes is typically related to its lower cost. The outstanding degree of strength of PETG material makes using a lower gauge thickness possible within some applications. The consideration of this feature makes it possible to use less material, therefore, reducing costs to produce a product. In many circumstances, this is a determiner to selecting PETG as the alternative to polycarbonate. Additional attributes of PETG are its machinability and formability. Most drilling, sawing, and routing can be performed with standard woodworking equipment. Heat forming of the products in this group is a bonus.
