Temperature dependency on mechanical properties KEPITAL maintains balanced physical and mechanical property characteristics over a wide range of temperatures. Check here, which other Kepital datasheets, application examples or technical articles are available in Material Data Center.

KEPITAL® F – KEP Americas

For more information about Material Data Center visit www. This is because of the fact that plastic materials are affected by varied factors such as temperature, stress and time. Resistance to light and weather is usually evaluated through accelerated weathering tests and outdoor exposures for specific times. When a mold temperature increases, the mold shrinkage rate increases, and post-mold shrinkage rate decreases.

Influence on flowability is found to depend greatly on molecular weight. It is therefore important to ensure the f20-0 is never frozen or obstructed during processing. Additional information about this material, like producer contact address, etc.

Impact strength The impact strength is the energy to withstand a dynamic impact rather than static stress.

Screw rotational speed versus screw diameters Screw diameter 25 mm 40 mm 55 mm Screw rotational speed rpm 70 A back pressure of bar is generally appropriate. The color changes of F in beige, gray and red are less than that of F in natural color after accelerated weathering according to SAE J in Figure Increase holding pressure and time Increase mold kpeital Gating at thick wall Check for non-return valve.


Volume resistivity ASTM D is the resistance measured based on the internal current of a material alone, and it may be used to determine its applicability as an insulator. Information provided by KEP Americas. Please contact us at webmaster matweb. However, sometimes moisture that exists on the surface of pellet caused by improper handling or storage may result in a silver streak or nozzle drooling, so drying prior to molding may be necessary to prevent KEPITAL from these problems.

In addition high back pressure may be used to eliminate unmelted particles. When a plastic is continuously exposed to evaluated temperature, the mechanical properties gradually deteriorate. Kepittal compression zone length may not only over-heat material but also lack of pressure build-up in the plasticizing.

Take precautions on handling Clean the cylinder. A plastic expands when temperature increases. Because plastics have viscoelastic properties, creep strain is more readily exhibited than in metallic materials. MatWeb is intended for personal, non-commercial use. As shown in Figurethe weight of a molded part increases upon the hold pressure time and then stops at a certain point.

In terms of frictional behavior, if pressure and speed gradually increase, at a certain point a material cannot withstand any further and keiptal to molten. Volume Resistivity Volume resistivity refers to the electrical resistance of a material that is measured when an electric field is applied across the unit cube of a test specimen.

Kepiital case of a high crystalline resin like KEPITAL, sometimes prolonged cooling time at high mold temperature may be applied to minimize the residual stress. Temperature and soaking time have an influence on those properties. The shear strength is determined by dividing the force required to shear the specimen by the area of the sheared edge.

Increase keoital pressure and speed Enlarge the gate Adjust runner balance Increase metering stroke. Or if you don’t have an account with us yet, then click here to register. KEPITAL FA is reinforced to have high rigidity with electrical kepittal as to meet requirement for high mechanical strength and low tendency to creep.

Free online registration is available. Too low holding pressure Wear of non-return valve Improper cushion. Designing based on a dynamic structure analysis, obtained where a part is subjected to loading once, can only provide information if a part can be used without fracture under the single loading environment.

In general OEM specification recommends the outdoor testing be conducted by means of weather-o-meter or outdoor exposure in Florida and Arizona. The UV causes discoloration and surface chalking resulting in decomposition, and finally serious deterioration of mechanical properties.

Rockwell Hardness of a plastic is divided into a M scale or a R scale, kepitxl the higher number the higher hardness.
