| 备注说明 | UNILATE PBT is a semi-crystalline polybutylene terephthalate (PBT) material that exhibits excellent rigidity, toughness, and machinability. Additionally, UNILATE PBT offers dimensional stability and wear resistance that meets or exceeds that of nylon and acetal. Due to its superior chemical resistance andfood contact approvals, UNILATE is the preferred material for components in wet and dry food processing applications such as pistons, valves, feed screws, and forming/extrusion dies. For applications involving high speed wear, UNILATE is available in an internally lubricated grade, UNILATE Lf, that provides a much lower coefficient of friction compared to non-lubricated grades.PRODUCT ATTRIBUTES INDUSTRIES APPLICATIONS |
