In order to make the low temperature hot melt white black dtf powder supplier maintain sustained and healthy development on the basis of the original rapid development, efforts should be made to improve the following aspects.

1. Modification and upgrading of the original varieties through blending (blending), copolymerization, grafting and other methods to improve the comprehensive performance and application performance of hot melt white black dtf powder supplier. For example, improve heat resistance and stability of hot melt white black dtf powder supplier, reduce melt viscosity, improve bonding strength and washable performance, etc. The varieties and dosage of various compounding agents were studied, and the formulation was optimized. To meet the requirements of different uses and different bonding.

(1) Vigorously develop high-quality hot melt white black dtf powder suppliers

The gap between domestic hot melt white black dtf powder suppliers and imported hot melt white black dtf powder suppliers often lies in the stability of quality, which should be firmly established

Quality awareness, brand awareness. Make good use of raw materials, process equipment and quality inspection. Resolutely implement the IS09001 quality certification system and 1400 environmental protection certification system. Promote the stability and improvement of quality of hot melt white black dtf powder suppliers.

(2) Develop special TPUhot melt white black dtf powder supplier

In recent years, in addition to the traditional processes such as powder sprinkling, powder dot and paste dot, the domestic bonding lining coating processing methods have also been transformed to new coating processes such as double-point coating and cold transfer powder dot with Chinese characteristics. In order to adapt to the new coating processing methods, many hot melt white black dtf powder supplier factory has developed special hot melt white black dtf powder supplier powder, such as Tangshan developed type IV, type V PAhot melt white black dtf powder supplier powder; Qidong and other places have developed special hot melt white black dtf powder supplier powder for cold transfer powder. In addition, for example, the compound of the polyester air variable silk upper and the lining cloth of the army shoes is also used as a special hot melt white black dtf powder supplier. For example, special hot melt white black dtf powder suppliers for automotive filters and reflective materials are also being developed, which greatly broadens the application scope of hot melt white black dtf powder suppliers.

(3) Vigorously develop compound hot melt white black dtf powder suppliers

The main methods to develop compound hot melt white black dtf powder supplier are blending, copolymerization and grafting. For example, adding A certain amount of PS, EⅥA resin and tackifier resin to the hot melt white black dtf powder supplier can improve the bonding strength and reduce the melt viscosity. For example, polyamide hot melt white black dtf powder supplier is modified with polyacid and polyol, and there is amide bond (-0-NH-); Combining the common advantages of polyester hot melt white black dtf powder supplier and polyamide, it is a new kind of hot melt white black dtf powder supplier material. It has excellent resistance to washing and dry cleaning. This is the PEA Compound hot melt white black dtf powder supplier. In the past few years, factories in Jiangsu and other places have tried to hot melt white black dtf powder suppliers, and achieved certain results.

2. To accelerate the research and development of new products of hot melt white black dtf powder supplier. With fast and healthy development of our country's national economy,hot melt white black dtf powder supplier has been favored by the majority of consumers, and the application of hot melt white black dtf powder supplier continues to expand: at the same time, it is also for hot melt white black dtf powder supplier makes higher demands.

1) Thermoplastic polyurethane elastomer hot melt white black dtf powder supplier

Thermoplastic polyurethane elastomer hot melt white black dtf powder supplier is prepared by prepolymer method with polyester (polyether) polyol as soft segment and diisocyanate and chain extender as hard segment. Its soft and hard segment composition, structure, relative molecular weight, chain extender, isocyanate index, etc., have a great influence on the mechanical properties, crystallization properties, bonding properties and heat resistance of hot melt white black dtf powder supplier.

2) Reactive polyurethane hot melt white black dtf powder supplier

hot melt white black dtf powder suppliers generally use thermoplastic polymer as the base material, which is easy to produce creep and has certain limitations in heat resistance. Reactive hot melt white black dtf powder supplier can further react a cross-linked curing after cooling and curing, which can greatly improve its heat resistance and medium resistance. Combine the advantages of traditional solvent-based adhesives and thermoplastic hot melt white black dtf powder supplier. The field of application will be further expanded. Reactive polyurethane hot melt white black dtf powder supplier can be divided into closed polyurethane hot melt white black dtf powder supplier and wet curing polyurethane hot melt white black dtf powder supplier.
