What does PBT stand for?
PBT is the acronym that stands for polybutylene terephthalate (PBT).
What is PBT material?
PBT is the second most important commercial polyester. It is a semi-aromatic thermoplastic that can be easily molded and thermoformed. Depending on the cooling rate and molding process, it is either amorphous or semi-crystalline. PBT has many beneficial properties, such as high strength and toughness, good abrasion and heat resistance, low creep at elevated temperatures, good chemical resistance, and excellent dimensional stability, especially when glass-fiber reinforced.
What is PBT plastic used for?
PBT is used in electrical and automotive applications, including plug connectors, relays, keyboards, switches, distribution boxes, and more.
Is PBT plastic safe?
Polybutylene Terephthalate (PBT), a high-performance thermoplastic, is a great choice for food packaging processing applications since it is FDA- and USDA- approved for use with food.
What is the difference between PBT and PET?
PBT is closely related to other thermoplastic polyesters. Compared to PET, PBT has slightly lower strength and rigidity, slightly better impact resistance and glass transition temperature. PBT and PET are both sensitive to hot water above 60 °C (140 °F).
In some applications, PBT competes with PET. When compared to PET, it has lower strength and rigidity. Yet PBT is more flexible and tougher with a higher impact strength, and it has a lower melting point and crystallizes faster than PET.
