Degussa AG Vestodur® X7390 Heat Stabilized PBT

 

Subcategory: Polyester, TP; Polybutylene Terephthalate (PBT); Thermoplastic

Material Notes:
Description: VESTODUR X7190 and X7390 are unreinforced, heat-stabilized and polymer modified polybutylene terephthalate (PBT) compounds with low shrinkage for extrusion. The compounds are especially suitable for the manufacture of stiff, small diameter tubing, e.g., loose buffering for fiber optics. VESTODUR X7390 has increased hydrolysis and heat resistance. Compared with standard PBT compounds X7190 and X7390 are harder. Therefore, they can also be used to protect as outer sheaths to protect electrical cables from the chewing of rodents. Both compounds contain a processing aid which facilitates feeding in the extrusion process.
