Information provided by KEP Americas. However, to increase the efficiency of the dispersion of a color masterbatch color concentrates or pigment, higher mixing by increasing back pressure may be required. If an insulator is inserted in an electric field, electric charges in the insulator are separated into opposite electric charge directions of the electric field.

Creep is the total strain of initial elastic deformation and plastic flow for loading time. Contamination with other material Black speck.

More importantly cycle time is closely related to part thickness. 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.

Heat ageing The heat resistance of a plastic may be obtained from measurement of melting point, heat deflection temperature and linear expansion coefficient. Since the degree of property deterioration depends upon environmental factors such as temperature, stress, and time, it is necessary to select a KEPITAL grade upon the designated environmental condition. Subscribe to Premium Services Searches: Dielectric Strength When a voltage is applied to an insulator and incrementally increased, if a certain limit is exceeded, large current suddenly flows to break down its insulation, and the limiting value of such voltage is referred to as dielectric strength.

In general, it is a most widely used characteristic to identify the electrical behavior of plastics. Low clamping force Too high injection pressure or holding pressure Too fast Injection speed Mold wear.

Please contact us at webmaster matweb. In this case, some treatments should be performed to prevent unnecessary problems. Recently, the xenon lamp, with a spectrum similar to that of sunlight, is generally used. In general the friction force causes a surface temperature increases at high velocity and a squeak noise under a certain pressure.

In addition, in some cases, pre-drying is effective in reducing odor, mold deposit and in kepiatl a kepigal appearance.

The heat resistance of a plastic may be obtained from measurement of melting point, heat deflection temperature and linear expansion coefficient. Thermoplastic materials are classified into amorphous and semi-crystalline polymers. By setting optimum hold pressure, molded parts product with consistent dimensions can be produced.


Washer fluid, Oils and Coolant etc. However, long term properties show time dependent behavior.


In particular, when designing parts such as pressure resistant containers, screw fasteners, insert formations and insertion parts for a kepitaal process, the creep property of material must be considered in advance.

For more information about Material Data Center visit www. Increase injection pressure and speed Enlarge the gate Adjust runner balance Increase metering stroke. At this time the gate of the part is solidified entirely and no more material can be incorporated. Check here, which other Kepital datasheets, application examples or technical articles are available in Material Data Center.

Friction is the resistance to sliding of two paired surfaces and is divided by dynamical friction coefficient or static friction coefficient. Any use of this information falls under the rules of our disclaimer. Privacy Policy Map Disclaimer.

Use the following short links lepital get directly to the properties of interest in this datasheet: With exposure to sunlight, plastics become very sensitive to ultraviolet rays. When a mold temperature increases, the mold shrinkage rate increases, and post-mold shrinkage rate decreases.

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. Any decision about the application of materials must be double checked with the producer of this material. The maximum shear stress at which a material can be maintained prior to shearing punching is referred to as shear strength. Therefore, when thermal degradation is noticeable, the cylinder should be flushed by purging out melt and the cylinder temperature must be reduced at the same time.

When the pressure is elevated to a certain extent, the resin and gas in a cylinder are explosively discharged through the filling hopper, f20-30 could cause serious injury to operators and damage to an injection molding machine.

To obtain a good quality product, the mold temperature must be consistently maintained so that the temperature distribution f220-03 the mold may be achieved uniformly. High moisture in granule Decomposition by over-heating Insufficient gas vent Air entrap into cylinder Contamination.


KEP Kepital® F Acetal Copolymer, Medium viscosity

When a voltage is applied to an insulator and incrementally increased, if a certain limit is exceeded, large current suddenly flows to break down its insulation, and the limiting value of such voltage is referred to as dielectric strength.

Radiation intensity and other conditions; filter combinations, temperature, cycle configuration, are specifically set up according to the test method. Physical and mechanical properties Thermal properties Tribological properties Electrical properties Resistance to fuels and chemicals Resistance to light and weather.

Lower the cylinder temperature Kkepital for gas vent Decrease injection speed. The user takes sole responsibility for the use of this data under the exclusion of every liability from M-Base; this is especially valid for claims of f20–03 resulting from consequential damages.

Standard medium viscosity grade providing well balanced properties kspital general injection molding and some extrusion. Specific volume As shown in Figurethe molding shrinkage of KEPITAL results from both its high crystalline alignment in solidification and its thermal shrinkage from the molten state to the solid state as a function of temperature and pressure.

The shear strength is determined by dividing the force required to shear the specimen by the area of the sheared edge. Impact strength can be measured in either notched or un-notched sample; however, it is generally evaluated after notch-processed on a specimen so that the stress of an impact load may be concentrated.

Unlike metals, most thermoplastic materials are insulators with a low thermal conductivity. When a plastic is continuously exposed kepitak evaluated temperature, the mechanical properties gradually deteriorate.

Troubleshooting keptal for KEPITAL Troubleshooting guide kepiyal KEPITAL Processing problem Causes Remedies Sticking in cavity Higher resistance to eject force Insufficient cooling time Decrease injection pressure and check for undercut or insufficient draft Clean mold surface Increase the number of ejecting pins Lower the mold temperature and increase mold close time Short shot Insufficient flowability by low melt or mold temperature Improper design with small gate or narrow flow channel Unbalanced filling F2-03 metering stroke Increase the cylinder temperature and mold temperature.

Improper compression zone length may not only over-heat material but also lack of pressure build-up in the plasticizing. Surface resistivity ASTM D is insulation resistance when certain voltage is applied across the surface of material.
