What is TPU( thermoplastic polyurethane) granules ?
TPU name is thermoplastic polyurethane elastomer rubber, this material can soften at a certain heat, but can remain unchanged at room temperature. Used in shoes to stabilize the role of support.
The so-called elastomer refers to the glass transition temperature is lower than the room temperature, the elongation at break is >50%, and the resilience is relatively good after the external force is removed.
What is hot melt adhesive grade TPU ?
TPU hot melt adhesive is a solvent-free new environmentally friendly material, the formula is based on the polygas wake as the basic framework for a variety of characteristics of the design, at room temperature is a solid, when heated above the melting point will melt into a viscous liquid for laminating process, cooling to room temperature and then back to a solid, belongs to the reversible thermoplastic materials, with good elasticity, softness, and low-temperature flexing characteristics, for a variety of heterogeneous materials with a very strong adhesive effect.TPU TPU hot melt adhesive film can be bonded to a variety of materials due to its high initial adhesive strength, and is widely used in garments, shoes, bags, handbags, clothing, medical, toys, footwear fabric lamination, silicone bra pads, lingerie accessories, waterproof zippers, trademarks lamination, computer 3C supplies, water-filled bags, inflatable bags, and foam composite products.
Because it is solvent-free and 100% solid, there is no risk of flammability or explosion during processing and transportation. In addition, there are the following advantages.
(1)Fast curing speed, cooling that is curing, high production speed, saving equipment space.
(2) Simple bonding process, less waste, no mixing problem.
(3) 100% solid components, can be completely utilized, less waste, can reduce transportation and storage costs.
(4) Wide range of substrates that can be attached, automated processing
(5) Excellent chemical and physical properties, with high adhesive strength and flexibility.
(6) No organic solvents, no VOC pollution problems
(7) Environmentally friendly materials, waste can be naturally degraded
What is the Processing method?
The way of use is divided into film, grinding and dissolution processing. The production of TPU hot melt adhesive film is generally used T-die extrusion processing, the thickness is controlled at 0.05 ~ 0.3mm, the production will be combined with the release paper or the use of high and low temperature double-layer structure, the downstream users to use the operation of simple, just put the hot melt adhesive film in the two layers of fabric to be adhered to the fabric, through the comfort bucket or the hot press soup can be laminated. Powder grinding process is to utilize the ultra-low temperature environment to reduce the material to below the glass transition temperature before grinding, downstream processing can be sprinkled with powder on the fabric to be laminated by hot press or infrared heating. Dissolution processing is to dissolve the hot melt adhesive in specific solvents, such as Chao, ketone, and other solvents, customers can combine with the existing solvent glue processing methods, because the TPU hot melt adhesive has a high degree of safety and stability, for the accompanying country transactions and delivery is very important, dry footwear and textile lamination is widely used.
| Product name |
TPU resin thermoplastic polyurethane granules /pellets |
| Appearance |
High transparent/white ,customized color |
| Characteristics |
1. A wide range of hardness: by changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and with the increase of hardness, the product still maintains good elasticity and wear resistance.
2. High mechanical strength:TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.
3. Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees.
4. Good processing performance :TPU can be processed by common thermoplastic material processing methods, such as injection molding, extrusion, calendering and so on. At the same time, TPU and some polymer materials can be processed together to obtain complementary polymer alloys.
5. Resistant to oil, water and mold.
6. Good reproducibility. |

Various applications hot melt adhesive grade of TPU resin:
1,Water stopping tape application, also known as heat ,sealing tape and water stopping strips
Tape composition can be a single layer or multi-layer film composition, the use of heat sealing tape lamination processing textile fabrics sewing line, in order to prevent water leakage. The product is mainly used for waterproof clothing, underwear, outdoor clothing, mountaineering clothing, fishing clothing, raincoats, medical dustproof clothing, blood impermeable pads, camping tents, down jackets, sportswear, casual wear, and other waterproof series products. Recently, due to the rise of functional clothing, boasting a good sense of skin contact, good elasticity, for the hot melt adhesive characteristics of the increasingly high requirements, including low-temperature adhesive strength, good fabric permeability, hydrolysis resistance, fast crystallization, soft, UV resistance and other functions.
2,Functional film
TPU hot melt adhesive film used in apparel above, mainly used to paste two layers of fabric, in the function of clothing will be because of the demand (feel, resilience, spit fog, transparency, etc.) to set the material characteristics, and also need to be examined in relation to the types of laminating materials, such as foam, PVC, Nylon, EVA, polymerase, cotton, etc., the film will be different from the setting, the choice of a number of professional investigation, this part of the product often need to be coupled with customer project development. This part of the product often needs to be matched with the customer for project development. In recent years, there has been significant progress in the application of shoe materials, through the introduction of TPU hot melt adhesive film in product design, the sports group to develop a seamless product, significantly reducing labor costs and reduce the weight, including some major manufacturers have adopted this approach to the production of high-performance shoes.
3,Glue for shoes
TPU hot melt adhesive will be dissolved in solvents such as butanone , sometimes also mixed with solid component is usually set at 15%, widely used in shoes or fabrics lamination, commonly used viscosity at 25 between 1600 ~ 5000cps, such applications need to consider the initial adhesion strength, heat resistance, adhesion time (Pot life) and other characteristics.
