Ticona VANDAR 4662Z PBT Vandar 4662Zis a high impact polyester alloy which contains 30% glass fiber loading. It is characterized by toughness, dimensional stability, and high modulus. Good weatherability and moldability are other key attributes.

Combining the seemingly contradictory properties of high ductility and good stiffness with the excellent chemical and thermal resistance of polyester makes for products that are hard to beat. Drawing on the basic properties of PBT enables Vandar alloys to achieve these results. These alloys are easy to mold and retain their impact strength down to -30° C (-21° F) and are available in both unreinforced grades and as compounds with glass fiber and minerals.

All unreinforced Vandar products have high impact resistance while retaining strength and stiffness. One grade additionally has a V-0 rating in the UL 94 flammability test down to a thickness of 0.85 mm (0.033 in). A key to the value offered by these Vandar products is that they have high impact even well below freezing, yet retain sufficient stiffness to prevent creeping and sagging at much higher temperatures. This property is particularly important in applications like automotive airbag covers, where ductile tearing is essential even in subfreezing deployment, but structural integrity must be maintained after baking under hot sun in a closed vehicle.

通過結合看似相互矛盾的高延展性和高剛性，加以聚酯所具有的優異的抗化學性和耐熱性，這些產品異常獨特。建立在PBT基本性能的基礎上, Vandar合金展現了上述的夢想特性。這些合金成型容易，并且在低達零下30℃溫度的情況下仍能保持良好的沖擊強度。Vandar合金有未增強品級，及玻纖和礦物改良品級。
