ULTRADUR® B 4500 FC NATURAL POLYBUTYLENE TEREPHTHALATE

Performance Polymers

(PBT) Polybutylene terephthalate, Chemical, PM CSSP NA (Attri), PM Product (Attri), Polymers

Medium viscous grade for compounding, injection molding and extrusion of flat films as well as thin-walled profiles and pipes in sensitive applications and with food contact. The BASF Ultradur® FC (Food Contact) grades enable the industry to develop products for food contact applications which are in compliance with different food regulatory legislations, including regulation (EU) 10/2011, regulation (EC) 2023/2006 (GMP for materials in food contact) or FDA regulation 21 CFR. Additional food contact compliances may also be available. Please contact your local representative or plastics safety (E-Mail: plastics.safety@basf.com). The products can also be offered as BMBcert™ and/or Ccycled™. Due to the Massbalance approach the product properties do not change. Abbreviated designation according to ISO 1043-1: PBT
