1、Hot melt powder is a kind of white powder (coarse powder: 80 mesh, medium powder 160 mesh, fine powder 200 mesh, 250 mesh) adhesive. Coarse powder is mainly used for flocking transfer, fine powder is mainly used for film sugaring transfer, because of its excellent adhesive properties are also often used in other industries as a high-quality hot melt adhesive, at room temperature bit high elasticity after heating and melting process viscous flow state, fast curing speed.
2、It has good melting properties and plasticity, has good temperature resistance, abrasion resistance, moisture resistance, acid and alkali resistance, corrosion resistance and heat resistance, and has a waterproof, moisture-proof and bubble-proof function, which can effectively prevent moisture from entering, prevent leakage, the use of hot melt powder can effectively improve the service life of the product.
3、It is applied to the printing of various textiles, leather, paper, wood and other materials and the preparation of various kinds of gum paste. The made adhesive paste has the characteristics of water resistance, good fastness, fast drying speed, not easy to block the net, not affecting the color of ink, etc. It is a new type of environmentally friendly material.
4、Characteristics: 1. As long as the mild bonding conditions can be obtained excellent washing fastness (can be as high as 60 degrees water temperature washing) and dry cleaning fastness 2. soft touch, good resilience 3. good chemical stability, can be stored at room temperature for a long time, does not deteriorate 4. harmless to human beings is a green product.
5、Usage: 1. heat transfer printing 2. making printing paste 3. screen printing 4. hot stamping flocking printing 5. doing hot melt adhesive
6、The difference between traditional hot melt powder and digital heat transfer powder.
①Traditional heat transfer does not need to be fused to digital heat transfer. The main reason is that the traditional heat transfer ink used in the glycerin and moisture contained in the ink is not so great, digital heat transfer needs to be fully dry, otherwise it will return to the oil.
② Traditional thermal fusion powder particles are relatively large, that is, the current digital thermal transfer powder belongs to the coarse powder, the size of 120-250 microns or so. Digital thermal transfer powder particles are generally used more in the powder and fine powder, fine powder particles are generally in the 80-160 micron, powder particle size in the 100-200 micron, the larger the particle size, the better the firmness, feel hard.
③Slightly different composition. Traditional thermal transfer powder can be selected according to the need to add different components of the powder to achieve different fastness, feel and tension; digital thermal transfer powder is mainly high purity tpu powder, pure tpu powder comprehensive feel, fastness, tensile strength is relatively average, can meet most of the scene; some mixed powder on the market in order to reduce the cost or to achieve a specific effect, but will be varying degrees of feel good but fastness is poor, Poor hiding power, easy to bleed color, or mixed with other cheap products and other problems. Powdery, hard to the touch, easy to crack.
