Product type
Polybutylene Terephthalate (PBT) is a thermoplastic engineering polymer known for its excellent mechanical properties and thermal stability. It is produced through the polycondensation of butylene glycol and terephthalic acid, resulting in a material that is both durable and resistant to chemicals. PBT is typically used in applications requiring high strength and rigidity, making it suitable for a variety of industrial uses.
| Material type | Thermoplastic polyester |
| Tensile strength | 50 to 80 MPa |
| Melting temperature | around 220°C to 230°C |
| Density | 1.2 to 1.4 g/cm³ |
| Color | Natural or custom colors available |
| Flammability rating | UL94 V-0 or V-2 |
When selecting Polybutylene Terephthalate, consider the specific mechanical and thermal properties required for your application. It's important to specify the desired grades, such as standard or modified types, as well as any necessary certifications for compliance. Additionally, indicate the required tolerances and quantities to ensure accurate pricing and delivery timelines.
