1. TPU polyester material: appearance and TPU Polyether Similarly, it is susceptible to hydrolysis; after a certain period of use, its internal components will dissolve in water, and it tends to yellow easily, relatively... Polyether Slightly stiff; not suitable for water-based products.
2. TPU polyether material: This material is odorless and environmentally friendly, with excellent wear resistance, tear resistance, tensile strength, and peel resistance. It offers high air tightness, strong toughness, resists yellowing, and is safe, non-toxic, durable, and highly resistant to cold, remaining elastic even at -35°C. It is particularly well-suited for inflatable water-based recreational products.
TPU materials are distinguished by their excellent wear resistance, outstanding ozone resistance, high hardness, high strength, good elasticity, and low-temperature resistance. They also exhibit good oil resistance, chemical resistance, and environmental resistance; in humid environments, polyether-based TPU demonstrates far superior hydrolytic stability compared to polyester-based TPU.
TPU elastomers are non-toxic and odorless, soluble in solvents such as methyl ethyl ketone, cyclohexanone, tetrahydrofuran, dioxane, and dimethylformamide, and also soluble in mixed solvents composed of toluene, ethyl acetate, methyl isobutyl ketone, and acetone in appropriate proportions. They appear colorless and transparent and exhibit good storage stability.
Depending on the hydroxyl component used, they can be classified into polyester-type and polyether-type. They can be used to manufacture plastic products, wear-resistant synthetic rubber products, synthetic fibers, rigid and flexible foam plastics, adhesives, and coatings, among others.
