Thermoplastic materials - Import export

At OptiMel, you get everything from a single source to optimally use low pressure molding technology for high-quality electronics encapsulation. Thermoplastic hot melts are used as encapsulation material. Due to their range of properties, amorphous thermoplastic polyamide granules are predominantly used in low pressure molding. Thermoplastic polyolefins are also available for special applications, which are used whenever sufficient adhesion cannot be achieved with the preferred polyamides on the substrates used (e.g. cross-linked polyethylene). Due to different raw material combinations, the range of properties of these hot melt granules varies in terms of mechanical strength, operating temperatures and resistance to various media. The hot melt molding materials combine a viscosity spectrum that is favorable for the low-pressure process with a wide operating temperature range (-50 / + 150°C) and, in some cases, very good adhesive properties.

Thrust bearing / Spherical axial bearings from igus d1 [mm]: Mechanical properties The self-aligning spherical igubal ® thrust bearings are very easy-to-mount units, which help to compensate for errors and prevent misalignments. The thrust bearing housing pad is made of the impact-resistant, stiff, thermoplastic composite material igumid G. The standard thrust bearing washer is made of iglidur® W300. This combination provides particularly good gliding and wear properties in relative movements. Loads The load carrying capacity of the spherical igubal® thrust bearing is very high in normal ambient temperature. In particular cases the load carrying capacity of the axial bearings should be checked in a practical trial with high constant loads and at higher temperatures. Coefficients of surface friction and speeds Taking the radial loads into account, maximum surface speeds up to 0.5 m/s rotating can be attained. Installation The axial bearing pad is mounted flush and secured. The spherical washer glides loosely in the pad and is held by the shouldered shaft mounted on it. Delivery program As standard, the spherical igubal® axial bearings are supplied in sizes of 5 to 20 mm. For other dimensions, please contact us. Special features Simple assembly Compensation of misalignments Compensation of edge loads Very good gliding and wear properties, low installation space When to use it? When you want to save weight When freedom from corrosion is required When a bearing with good friction coefficients is sought When not to use? When very heavy loads act When constant temperatures of more than +80℃ occur When high rotary speeds must be implemented. Thrust bearing / Spherical axial bearings from igus d1 [mm]:

Asparagus sorting chain - we also assemble assemblies! Asparagus sorting chain with unloader, made of thermoplastic materials. Of course, the material is approved for food contact.

Application: A set wire inserts fitted in the entrance hole of the connector will provide a very good strain relief without any protruding parts from the connector. Construction: • Thermoplastic material with a round or oval hole fit around a specific wire.

The multiple water quantity control system in modular design that is available in several versions fulfils not less than three requirements at the same time. It combines the advantages of the conventional water distributors, the impulse cooling systems and the continuously operating temperature control units while eliminating the disadvantages of each of these systems. The temperature control system disposes of up to 128 individually adjustable circuits and is suitable for the processing of polyolefins and technical thermoplastic materials. In case of the basic execution (itd B) the requested flow rate is adjusted manually and is then monitored by a flow meter and presented digitally and graphically on the central display of the control unit. In the standard execution (itd R) the water quantity is individually set for each circuit at the central operating unit and - if necessary - is readjusted automatically via a water quantity regulation valve within adjustable limit values.

The most simple way of welding thermoplastic materials is to use the ultrasonic manual welding device. This is particularly well suited for applications in prototype design, for processing of single products, small series and repairs. Regardless of caulking, swaging, staking, cutting, or spot welding, the HSG ultrasonic manual welding device is easy to use, provides variable power rating, and can be equipped with all types of conventional sonotrodes (35 kHz).

The BIO-POT®-straws are 69 % bio-based on starch (potatoes) and fibers and 31% on minerals, calcium and magnesium. They are completely biodegradable and quickly compost in industrial composting plants. The plasticizer-free, mineral oil free thermoplastic material contains a high portion of biologically sourced and genetically unchanged raw materials. Thus, the BIO-POT®-straws make a decisive contribution towards reducing strain on the environment. Only usable for beverages up to 30 Grad C. Durability ca. 18-21 month in dry environment under propper storage conditions. The BIO-POT®-straws can be incinerated without residues and are also recyclable. Made in the EU, the raw material for the straw production originates from Germany. Available in the colors black and white - 500 pcs per bag as straight or flexible straw and in different diameters and lengths. Packed either in polybags or in the semi-transparent and also bio-degradable “Compost OK” bag.

The ultrasonic riveting makes possible an interlocking bonding of two thermoplastics or of thermoplastics with dissimilar materials, e. g. thermoset materials or metals. In this process the sonotrode serves as a re-forming tool. It determines the forming of the riveting pin. During the holding time (cooling phase) the sonotrode serves also as fixation stamp, thus the melted material cools down under pressure.

We are successfully helping to convert a rapidly growing plastics waste stream into new life plastic products with our Dryflex TPE compounds based on Post Consumer Waste. The thermoplastic elastomer materials were developed to address demands in the automotive industry, which is obliged to use increasing quantities of post consumer waste and operate under the EU ELV Directive to ensure recyclability at the end of each vehicle’s life. The materials contain a high volume of post consumer waste from 33% to 80% by weight. Recyclate consists of polypropylene drawn from automotive mouldings, which are cleaned and re-ground and rubber tyre crumb from both OEM and after market tyres. Apart from the obvious benefit of recycling, the material exhibits other advantages when compared with virgin materials particularly its superior Ultra Violet, and weathering resistance and sound reduction properties.
