PET 与 PBT

With excellent flow and mechanical properties, plus excellent processing characteristics, Arnite PET & PBT are applicable in high precision components for a broad range of automotive, electrical and electronic, consumer goods, food packaging applications and more. Both polyethylene terephthalate and polybutylene terephthalate are hydrolysis resistant—they are dried prior to injection molding. Yet, PET requires an even lower moisture content than PBT. Arnite has exceptional dimensional stability and high strength and stiffness at ambient conditions because of low moisture absorption.

In the automotive industry, many applications are located in high humidity and heat environments.  Thus, hydrolysis and heat resistance is very important. For applications such as connectors, sensors and control devices, manufacturers need materials they can rely upon to resist hydrolysis in these demanding environments, and you can look to the HR-PBT portfolio of material solutions to deliver exceptional hydrolysis resistance.

By avoiding possible corrosion problems with metallic contacts, Arnite PBT achieves excellent high-temperature performance without the need for heat stabilizers. Plus, it’s very low moisture absorption ensures high dimensional stability for safe and reliable parts.

In addition to excellent mechanical properties, Arnite PET & PBT deliver a cost-effective material with swift processing times and global security of supply. Arnite HR-PBT portfolio addresses even more stringent testing validations as the trend towards electric-powered and autonomous road vehicles increases.
