MOCOM Compounds ALCOM® PBT 700/9 is a pre-drying conditions polybutylene terephthalate (PBT) with a matt (textured) surface, used in the building and construction, fixtures/fittings, and household goods. Typical applications include kitchenware, fixing elements, and more. Processing injection molding requires a melt temperature of 250-270°C and a mold temperature of 60-100°C. For proper use, keep in a dry, protected environment, not above 30°C, and pre-dry in a dry air (dessiccant) dryer at 100-120°C for 2-4 h, or in an air circulating dryer at 100-120°C for 4-8 h, depending on the moisture content.

Polymer Name: Polybutylene Terephthalate (PBT)

Processing Methods: Injection Molding

Flexural Modulus: 2700.0 - 2700.0 MPa
