Our engineers also create new momentum in the market by developing their ideas for spinning mills. Here again, the focus of attention is placed upon the individual customer request. The widest range of color nuances or degrees of matting can be achieved at each spinning position at any time for individual PET or PBT filament yarns, such as POY or FDY speciality yarns (NC, HC or micro).
We also offer complete plants, for example for the manufacture of tyre cord. The starting material is converted into PET granulates and finally into bales of dipped tyre cord. The EPC Group assumes overall responsibility for all the internal interface areas. This means that our customers have only one contact, who is responsible for the project, and coordinates and controls all matters concerning the project up until the plant is handed over to our customers' experts. At the customer's request, we will carry out a complete warranty procedure for the entire production chain – from the polymer to the baled end product – to verify the output capacity of our concepts and production plant.
We also help our customers to introduce individual new products in their existing plants, and with the individual modernization measures, such as calculating new polymer pipes with the EPC Group's own software and database.
The core competence of the engineers in the EPC Group in this field is the manufacture of endless textile and technical filament yarns. However, staple fiber technology and its specialities, such Bico spinning, are also among our specialities, for some of which we have over 40 years of experience.
EPC variPLANT® gives you the following competitive advantages:
EPC PETvantage® is the most cost-effective alternative to investing in a new plant. Depending on the plant configuration, a return on the investment is usually achieved in less than 2 years. In most cases, the main reactors do not need to be replaced. Operational safety, product qualities and production capacities are increased by a multiple, depending on the basic design of the plant and the space available on site.
EPC PETvantage® generates very high profits, mainly through quality assurance and the consequent greater competitiveness:
Commercial and qualitative advantages of EPC inside PET®:
EPC Group has vast experience in the polymers and fibers industry and offers complete engineering packages in delivering world-class polymer/fiber manufacturing plants. For the production of high-quality PETG, PCT, PCTG and PCTA, EPC Group offers its modern CHDM Hydrogenation Technology for the production of top-grade CHDM.
EPC’s highly efficient and flexible continuous hydrogenation process guarantees a feasible production of top quality CHDM. Furthermore, having your own state-of-the-art CHDM production line will ensure a continuous supply of high-grade CHDM as raw material for the manufacturing of high value polyesters resin for the fast growing technical applications in electronics, food and medical packaging, construction components and consumer goods.
In the refining process, the desired additives are added to the raw polymer material in a mixer, and intermingled in the extruder. The melt is then allowed to solidify again in a cooling trough, after which it is cut up in the granulator. With the masterbatch process, EPC enables its customers to change the products their plants produce quickly and keep cleaning costs low. Energy-efficient extruder systems are long lasting, and economical because the waste heat from the extruders is fed back into the entire plant for re-use.
Theprocess patented by EPC enables the material to be optimally substituted by means of nitrogen evolution in combination with a higher pressure. This significantly reduces the extract content in the granulate, while at the same time enriching the extract water to about 18%, and achieving a considerably more consistent retention time. This minimizes fluctuations in the extraction concentration.
The extraction process developed by EPC can also be used in existing plants without requiring any large investments or lengthy modernisation times. A special device distributes nitrogen into up to 16 extraction zones in the column. Granulate flows from top to bottom through a packed bed in the device.
The nitrogen and extract water are fed upwards in a counter-flow. The extraction rate depends on the number of trays, which is determined on a case by case basis. The device consists of trays arranged one above the other. Nitrogen is distributed homogeneously through these trays.
Advantages of the solution patented by EPC:
EPC has developed a reactor material based on a special aluminium alloy that is inert under the reaction conditions (no material abrasion), and consequently has no effect on the reaction medium (no uncontrolled reaction behaviour). The material is used in the manufacture of the reactor and in the up and downstream stages involved in the polymerization reaction. Plant components made of this material do not have to be replaced during the projected lifetime of the plant.
Avoiding deposits building up lengthens production cycles. Less frequent cleaning increases the production capacity and reduces the use of cleansers. The material has strength properties similar to those of steel, and can be worked with conventional machining and forming processes (rolling, bending, grinding, polishing, welding).
Choosing EPC variPILOT® is a good decision. We examine the site, and specify the future location of your pilot plant before we configure it. We plan and construct your specific test plant in accordance with the conditions, the product parameters and your requirements. We deliver your variPILOT®plant pre-assembled, so it can be quickly and easily installed and commissioned.
