Polyester thermoplastic engineering polymers (PBT and PBT blends) for injection moulding.

The Raditer range includes PBT polyester engineering thermoplastics for injection moulding of plastic components for the automotive, electrical/electronics, industrial and consumer goods industries.

Versatile polyester engineering plastics with a wide spectrum of applications

Polybutylene terephthalate (PBT) is a semi-crystalline polyester with excellent technical properties, well suited to a wide variety of uses. PBT engineering plastics are used to manufacture plastic components for a variety of applications, from automotive to electrical/electronics, technical industrial and consumer goods.

Raditer® PBT engineering polymer characteristics

Raditer® engineering plastics feature high stiffness and mechanical resistance; good resistance to high temperatures and UV radiation; high hardness and wear resistance; excellent electrical insulation properties and vey low moisture absorption.

Compared to polyamides, PBT engineering plastics have similar mechanical properties in the dry state, greater specific weight, lower melting point than PA6.6, greater dimensional stability thanks to negligible sensitivity to humidity changes, and lower impact strength, particularly with respect to conditioned polyamides.

To date, Raditer® products are available in a number of grades: unreinforced, impact modified, reinforced with glass fibre and mineral fillers, special formulations designed to fulfil specific requirements, and PBT/ASA blends to enhance appearance and dimensional stability.

Also available are specialities specifically formulated to enhance hydrolysis resistance in critical applications, such as sensor housings for automotive electronics.

Raditer PBT engineering plastics processing

Raditer® engineering plastics feature good moulding processability and are typically processed by injection moulding. A pre-drying system before the moulding process is needed for optimal processing, and special care must be taken to avoid moisture absorption before moulding occurs.
