What are the material of hot melt adhesive TPU granules ?
Hot melt grade polyester TPU (thermoplastic polyurethane elastomer) particles are a polyester type thermoplastic polyurethane elastomer. TPU is a polymer material formed by the reaction of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low molecular polyols (chain extenders). Its molecular structure is composed of rigid blocks obtained by the reaction of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and chain extenders, and flexible segments obtained by the reaction of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols.
What are the chemical properties of hot melt Adhesive grade TPU?
Hydrolysis resistance: It has good tolerance to water, is not easily hydrolyzed, and can be used in humid environments.
Oil resistance and chemical resistance: It has a certain tolerance to oils and some chemicals, and can resist the erosion of some chemicals.
Aging resistance and weather resistance: It has good aging resistance and weather resistance, stable performance during long-term use, and is not easy to age quickly due to environmental factors.
What are the processing characteristics?
Good hot melt: It has good hot melt, can melt quickly after heating, and is easy to process and shape. For example, it can quickly achieve bonding in the production of hot melt adhesive film and heat sealing tape.
Solubility: It is soluble in organic solvents such as esters and ketones, such as ethyl acetate, MEK, DMF and other solvents, which is convenient for application in inks, glues and other fields.
Fast crystallization speed: The crystallization speed is fast, so that the product can be quickly solidified during the molding process, improving production efficiency.
Strong initial adhesion: It can quickly generate strong initial adhesion during the bonding process to ensure fast and firm bonding.
