In the recent years Polycarbonate has undergone a very fast change from a former engineering to a mass polymer. Despite the loss of volume markets like optical memory discs and food applications the overall demand for Polycarbonate is continuously growing.
China – originally a pure import market for PC – has new, own capacities by the worldwide well known industry leaders. On top of such international investments there are at least 7 Chinese industry groups who already have own, local capacities or will launch new capacities in the near future.
China increasingly is becoming an important potential supplier for polycarbonate. This fits to our philosophy to offer technical and qualitywise high value materials at competitive prices to Europe.
Already since the late 2019 DREYPLAS and Chinese LUXI ( http://en.luxichemical.com/ ) entered into a sales agreement for Europe’s German speaking countries. Luxi started back in 2015 and has since the first expansion in 2018 already a capacity of 200,000MT PC resin.
Basically LUXI produces MFR from 3 to 20. All grades will be also available with UV protection.
To be costwise for the customers most competitive DREYPLAS is concentrating in the first phase on few grades like MFR 9 and 15, MFR 9 also with UV. As soon as the supply prooved to be routine business also other MFR shall be made available step by step.
Existing customers are served from local stock in Germany. New customers may have a lead time of up to 8weeks for the first delivery. After that stocks can be increased to ensure a lead time of few working days.
DREYPLAS is represented in China directly with a reliable group partner. By that we are able to locally control the cargo logistics as well as the quality and make sure that our standards are kept.
LGMMA/Korea – one of leading manufacturer for PMMA and SMMA – will increase during 2020 it’s production capacities to 260.000MT. By this increased capacity it will be possible to expand the presence also in Europe further.
In addition to standard application in injection and extrusion molding DREYPLAS is especially concentrating on specialities like
DREYPLAS suppliers containerloads directly from Korea to customers. Smaller quantities as well as buffer quantities are delivered from European stockpoints within few days after order.
Newly added to the DREYPLAS product portfolion is alumina as additive to improve the thermal conductivity. We understand the following materials as direct competition to our material:
Our products in platelet shape are produced by Japanese DIC. We see the following advantages to established materials:
Current sph Al is consumed by more than 10,000MT/a worldwide. Our commercial available platelet grade AP-10 has higher cost than sph Al, finds however even today application i.e. in mixture with sph Al to improve the meachanical properties at a moderate increase of compound price.
Compared to AlN and BN the price difference is smaller. It is expected that the better abrasion properties and the still higher heat conductivity are the reason to shift to platelet Al.
Current we have access to a few hundred ton production capacity, a substantial increase is targeted as soon as possible.
Due to their high molecular mass and the resulting viscosity, ultra-high molecular weight polyethylenes (UHMW-PE) can only be processed mechanically with a high degree of expense. However, the Japanese company Mitsui Chemicals has developed a special UHMW-PE as a granulate – brand name: LUBMER – which can be turned into a flowing form and can therefore be directly processed in injection moulding or extrusion processes. Costly reworking and deburring operations are no longer necessary. Various new applications for UHMW-PE have already been developed in cooperation with the distribution partner DREYPLAS GmbH. The product variants retain their ultra-high-molecular properties even after processing and, due to their mouldability, allow for the production of finished parts in large series. All LUBMER variants will be presented by DREYPLAS at FAKUMA in Friedrichshafen.
“Ultra-high-molecular-weight polyethylene as a powder must first be pressed before the desired components can be mechanically worked out from blocks or ring moulds, all at great expense,” explains Dipl.-Ing. Norbert Hodrius, Product Manager at DREYPLAS GmbH. “Due to their high molecular mass and the resulting high viscosity, these polyethylenes are unsuitable for injection moulding and extrusion in principle.” This is now possible with the LUBMER-type UHMW-PE: Through changes in the polymer structure, the plastic is adapted in such a way that very good flow properties are achieved. This ensures an even distribution in the injection mould and prevents defects such as surface roughness. However, the basic properties of the plastic, such as its sliding capacity, abrasion resistance and heat deflection temperature, remain unchanged.
Thanks to the improved sliding properties, more finished parts can be produced in series from this durable plastic: Several components can be injection moulded from one mould with short cycle times using multi-cavity tools. Post-processing or chippings, as is the case when using UHMW-PE semi-finished products, are eliminated. Despite the special production process, the variants L3000, L4000 and L5000 have a very high wear resistance and impact durability, whereby the L5000 is especially suitable for extrusion. They also behave like standard polyolefins, which is evident in their favourable chemical resistance and electrical properties. “We offer comprehensive technical advice as well as laboratory analyses prior to project planning,” adds Hodrius. The customers benefit from the distributor’s experience. DREYPLAS offers its customers not only logistics and quality-tested goods but also just-in-time delivery and worldwide access to high-performance polymers and additives.
DREYPLAS GmbH distributes additives, high-performance polymers and adhesive raw materials for the plastics and chemical industry throughout Europe. The portfolio mainly consists of products from large and renowned – mostly Asian – manufacturers, some of which have long-term supply contracts with the company. Mexico, USA and Canada are covered by the US subsidiary DREYTEK Inc. founded in 2015. The subsidiary DREYCHEM GmbH develops and distributes very highly effective cleaning granulates for injection moulding and extrusion – also in the high-temperature range. Another member of the group, EFP GmbH, is one of the few suppliers of polycarbonate, PC/PMMA and other special films for the printing, household appliance and electronics industries as well as for mechanical engineering.
