K glue, also known as k-resin, is styrene-butadiene copolymer (SB) , with good transparency, gloss, and impact resistance, and the price between PS and PC, therefore, widely used in the manufacture of non-fragile transparent products, such as: cups, lids, bottles, hinge-type boxes, hangers, food and pharmaceutical packaging supplies, and so on. K glue is made by copolymerization of styrene and butadiene, polystyrene has high transparency, good processability, disadvantage is brittle, butadiene can be polymerized into rubber, with elastic impact resistance, the two copolymers, the defects of polystyrene were improved, and the polymer with good comprehensive properties was obtained. K glue is an amorphous polymer, good fluidity, and processed products, the appearance of smooth, shiny, high transparency. Suitable for injection molding, hollow blow molding, extrusion and other processing methods, can be processed in most common equipment, without changing the equipment and mold. Thermal properties: because K adhesive is an amorphous polymer, its melting point is not obvious, the thermal deformation temperature is 77 ° C, when the temperature is higher than 177 ° C, the mobility of the polymer increases, but after the temperature is higher than 260 ° C, the fluidity of the polymer increases, its fluidity begins to be unstable. If the barrel temperature is too high or the residence time is too long at medium temperature, the polymer will be degraded, which will lead to the appearance and performance of the products become worse, such as the decrease of transparency, discoloration, brittleness and so on.
2. Optical Properties: K Glue is an amorphous polymer, which has less interference with light than dense crystalline polymers. As a result, the turbidity is very small (1-3%) and the transparency is excellent (89-91%) , in order to improve the transparency, we must improve the mold surface finish and select good processing conditions. Four. Chemical Resistance: the chemical resistance of K gum is poor, organic compounds, such as alcohols, ketones, esters, and aromatic compounds will make k material soften and even dissolve, oils and diluted acids and bases can attack polymers, but the rate and severity of erosion depends on the product's design and storage conditions. Therefore, the compatibility of the actual product with the K material should be tested.
