SECULENE® PP: HI-GRADE COMPOUNDS MADE FROM SECONDARY PP-MATERIALS

PROFILE LEADING IN ENVIRONMENT-FRIENDLY PP COMPOUNDING

As the foremost producer of high-grade PP compounds from secondary materials, the ECOBAT Technologies group is a leading partner for the automotive industry and its subcontractors.

The company operates several plastic extrusion plants for polypropylene (PP) throughout Europe. In the UK, ECOBAT produces high-grade PP for non-automotive applications. The PP compounds produced in Germany under the tradename Seculene® set standards in the world of polypropylenes. They are on a par with those produced from primary raw materials and are renowned for cost efficiency and flexibility of application. The main application is in the automotive industry.

In close cooperation with industrial partners and based on research extending over a number of years, many different types of Seculene® PP have been developed, a product which was and is still being continuously optimised. Using an all-encompassing concept for a self-contained PP-material cycle – recycling, compounding, distribution and service – ECOBAT qualifies as a company offering future-oriented solutions.

In addition to the process-controlled recycling of PP-chips from secondary raw materials, the production of PP-compounds according to customers’ requirements is one of the core competences of the ECOBAT group. With an annual production capacity of more than 50,000 tonnes of Seculene® PP ECOBAT, as an innovative service provider for the plastic industry, leads in developing ground-breaking application possibilities.

PRE-TREATMENT

Starting materials for Seculene® PP are mono-fraction polypropylene chips obtained from the company’s own pre-treatment of battery scrap and increasingly other PP, PP/EPDM- and TPO-materials from post-consumer and post-industrial streams. The main source of scrap is automotive injection moldings and end-of-life vehicle recovery. These are cleaned

thoroughly in multiple stage cleaners before being charged to a wet cutting mill and cut to granules. Metal residues are then separated using density separators. The charge is then dried in mechanical dryers before being fed to air classifiers for separating out particles of paper, wood and rubber. The thus cleaned granulate is transported pneumatically to raw material silos of the compounding plant.

COMPOUNDING

The main feature of compounding is a blending technology allowing the creation of precise formulations based on predefined specifications and individual customer product requirements. Material compositions for specific uses are adjusted by blending mineral fillers, additives or colour batches, the whole then being processed to

high-grade PP compounds. A comprehensive quality control – covering the process technology and more – of the process parameters like formulation, temperature, pressure or flow characteristics ensures that the Seculene® PP manufactured is always of a consistently high quality.

TAILOR-MADE MATERIALS

Seculene® PP, made solely from secondary raw materials, is a top quality brand. Its properties of density, impact strength, elongation and flow characteristics, are equivalent to those of products manufactured from primary materials.

Often at short notice and specially tailored to the unique needs of customers for their applications, ECOBAT develops Seculene® compounds, which are competitive substitutes for new-ware. The consistent and reliable high quality of products made of this innovative material is effective proof of an economical and efficient use of resources.

Increasingly, the automotive industry focuses on Seculene® PP and involves ECOBAT right from the beginning in the development of new type generations.

This material has proved its reliability in such varied applications as wheel housing protector shells, underbody claddings, cable ducts and as water deflectors, guide rails or toolboxes. Seculene® PP is also being successfully used as housings for starter batteries or accumulators for industrial applications.

The high-grade PP for non-automotive applications is mainly used in the construction industry.

Currently, approximately 20 different PP qualities are produced at ECOBAT.
