PP belongs to non-polar polymer, has good electrical insulation, and the PP absorbs water very low, and the electrical insulation is not affected by humidity. The dielectric constant and dielectric loss factor of PP are very small and are not affected by frequency and temperature. The dielectric strength of PP is very high and increases with temperature. These are good for electrical insulation in wet and hot environment. On the other hand, the surface resistance of PP is very high. In some cases, anti-static treatment must be carried out first.
The PP belongs to a crystalline polymer, and its particles can not melt at a certain temperature. Unlike PE or PVC, it is softened with temperature during heating. Once it reaches a certain temperature, the PP particles rapidly melt, and within a few degrees, they can all be converted into molten state. The PP melt viscosity is lower, thus forming the liquidity is good, especially when high melt flow rate of melt viscosity smaller, suitable for large thin-walled products injection molding, such as washing machines. If the PP is slowly cooling in the air after leaving the mouth mold, the larger grain will be generated and the product will be less transparent. The result is that the molecular motion of PP is rapidly frozen, and the crystal cannot be formed. The membrane is completely transparent. The shrinkage rate of PP is relatively large, which is more than 2%, which is far larger than ABS plastic (0.5%).The forming shrinkage of PP can be changed with the variety of adding other materials, which should be considered seriously when making injection molded products with fit dimensions.
Compared with current fashion and mainstream water transfer, what are the advantages and disadvantages of heat transfer technology? In particular, the production of water transfer printing is more flexible and convenient, is not subject to the limitation of object area, shape, generally do not need special tools and equipment (as long as a piece of water transfer printing paper), so the applicable scope is more extensive, production costs are lower than the thermal transfer, very suitable for home users and small workshops, fashion ornaments shop. Thermal transfer because of the image is heated, its finished product after image color will be more solid than water transfer printing, not easy to rub off the case, it has corrosion resistance, impact resistance, aging resistance, abrasion resistance, high temperature resistant, fire prevention, can keep ten to the characteristics of the decades does not change color, so the thermal transfer technology is especially suitable for image retention have special requirements of electrical appliances, daily necessities, building materials, decoration and other items.
