产品说明

High-viscosity, plasticized, heat- and light-stabilized, impact-modified polyamide 612 compound for extrusion

VESTAMID DX9303 is a PA 612 extrusion compound developed for the production of tubing systems with higher requirements for heat resistance.

The melting point of VESTAMID DX9303 is about 35°C higher than PA 11 and PA 12 compounds, allows higher peak temperatures in use. Thereby this compound fulfills the increased demands resulting from higher

temperatures in the engine compartment. If it is intended to use VESTAMID DX9303 for fuel lines, certain preconditions must be observed. The Technical Marketing assists you in finding the suitable VESTAMID compound.

At temperatures above 100°C tubings of VESTAMID DX9303 allow a higher pressure load than tubings made of PA 12 compounds with comparable flexibility.

The material absorbs only little moisture. Therefore dimensions and properties of parts are nearly unaffected through ambient conditions.

The process temperatures should be in the range of 240-270°C. More information about processing and storage you will find in the brochure „Handling and Processing of VESTAMID."
