Materials and application know-how

POLYMETRIX is a specialist for the thermal treatment of bulk materials. Our main focus are treatment processes for virgin and recycled polyesters, polyamides and other polymers.

Typical applications for the products from our plants are packaging materials like PET bottles, high tenacity yarns like PA air bag fibers or straps made from 100% recycled PET. The demanding properties for these applications are achieved with our treatment processes such as solid state polycondensation (SSP), drying and conditioning or crystallization.

To design our processes we test all relevant material characteristics in our in-house technical facilities with respect to processing and the demands of the final application. The test results are used for process simulations and the subsequent scale-up to industrial-scale plants.

vPET for food packaging

Virgin PET (vPET) is produced form oil or renewable resource based monomers. The POLYMETRIX solid state polycondensation (SSP) technology is the last step in the manufacturing chain and upgrades the PET to fulfill the demanding quality and food safety requirements for food packaging applications.

rPET for food packaging

POLYMETRIX PET recycling technologies make it possible to convert post-consumer PET bottles into recycled PET (rPET) suitable for direct food contact applications. The rPET pellets are fully compatible with virgin PET and are used for beverage bottles and food trays with up to 100% rPET content.

vPET for technical applications

POLYMETRIX SSP process technology is particularly well suited to produce PET pellets with very high viscosity. The high viscosity PET pellets are required for the manufacture of high tenacity yarns, packaging straps and other specialties.

rPET for technical applications

POLYMETRIX SSP process technology is particularly well suited to produce rPET pellets or flakes with very high viscosity. The high viscosity rPET is mostly used for packaging straps but it also finds its way into other high tenacity applications.

Polyamides for technical applications

Polyamide (PA) pellets for high-quality textiles and technical applications are manufactured using POLYMETRIX conditioning and SSP process technology. The processes adjust the viscosity and the equilibrium moisture content in the PA pellets to the requirements for subsequent spinning or molding processes.

Other polymers

POLYMETRIX process technologies are used to treat various types of polymers according to the requirements for subsequent processing or packing. The technologies are particularly suitable for processing polymer pellets or flakes, such as polybutyleneterephthalate (PBT), polytrimethyleneterephthalate (PTT), polycarbonate (PC) and poly lactic acid (PLA).
