1.Different applications
GK is a model that will not be mass-produced, because a mold filled with more than a dozen sets will be discarded, so the price is generally more expensive. Generally, the white model requires the buyer to polish, assemble, and paint by himself, which is much more difficult than the general model making.
PVC used to be the world's largest production of general-purpose plastics, and it is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.
2.Different features
GK models are usually designed by a stylist to design a gray mold, and then open the mold to make a white mold. Because of the corrosiveness of the resin and the complexity of mold opening, it is very difficult, so the price is generally very expensive. Because of the characteristics of resin materials, it is very suitable for expressing very detailed details and characters.
PVC is a white powder with an amorphous structure. The degree of branching is small, the relative density is about 1.4, the glass transition temperature is 77~90℃, and it starts to decompose at about 170℃. The stability to light and heat is poor, above 100℃ or after a long time. Sun exposure will decompose to produce hydrogen chloride, which will further autocatalyze the decomposition, causing discoloration, and the physical and mechanical properties will also decline rapidly. In practical applications, stabilizers must be added to improve the stability to heat and light.
