TPU applications in wearable devices - Guangyuan Ruifeng New Materials

Category: TPU (popular science, no product)

Release Time: 2020-07-10

Summary: After nearly two years of development, the mainstream material solutions for wristband products are roughly as follows: The ideal material should combine the advantages of TPU/TPE/SILICON: aging resistance, wear resistance, non-dust, chemical resistance, good coating, silky soft (75A), comfortable contact, and dry breathability. The improved TPU series materials currently being developed by PepsiCo are suitable for various watch straps and bracelets, with performance close to TPSIV and good wear resistance.

1. TPU Applications in Watch Straps and Wristbands

After nearly two years of development, the mainstream material solutions for wristband products are roughly as follows: The ideal material should combine the advantages of TPU/TPE/SILICON: aging resistance, wear resistance, non-dust accumulation, chemical resistance, good coating properties, silky softness (75A), comfortable and dry feel, and breathability. The improved TPU series materials currently being developed by PepsiCo are suitable for various watch straps and wristbands, with performance close to TPSIV and good wear resistance.

2. TPU Applications in Phone Cases

Good fluidity allows for injection molding of ultra-thin plastic products, especially suitable for the production of ultra-thin phone protective cases. It offers excellent transparency, easy molding, easy coloring, and a very comfortable feel.

Product characteristics: High-quality material, excellent tensile and tear strength, 90A-95A hardness requirement; excellent coating properties, can be secondary molded with ABS and PC with excellent results; good transparency and weather resistance, with a certain yellowing resistance; good scratch resistance, abrasion resistance, and dirt resistance; phone protective case feels good, skin-friendly, fashionable and beautiful, thick, and can perfectly protect your phone; good material fluidity, injection molding, color can be adjusted according to customer needs!

3. TPU Applications in Waterproof and Breathable Membranes

TPU has excellent high tensile strength, high pulling force, toughness, and aging resistance, and is a mature environmentally friendly material. TPU is an environmentally friendly polymer, the Chinese name is thermoplastic polyurethane, also known as a waterproof and breathable membrane. The new TPU waterproof and breathable membrane environmentally friendly material is a major breakthrough in the application of waterproof and breathable fabrics. It overcomes many shortcomings of PVC and PU leather. It not only possesses most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties, so it is also known as the material of the future.

TPU waterproof and breathable membranes are an intermediate between rubber and plastic, and can be divided into low, medium, and high waterproof and breathable films according to the process.

TPU waterproof and breathable membranes use elastomers as the main material. They have excellent elasticity and high strength, and have physical properties in waterproof characteristics that other materials cannot match (can withstand water pressure over 10000mm, the thinnest can reach 0.012mm); in addition to high waterproofness, TPU films also have excellent moisture permeability.

4. TPU Applications in Underwear

Straightforward, improves sewing efficiency, reduces labor costs, reduces skipped stitches, improves the safety factor during sewing, smooth and straight, no pulling required, the sewn parts are smoother after sewing, enhancing the brand image of the garment; good permeability, better achieving an invisible effect, zero breakage rate when encountering needle pricks, better toughness; evenly distributed particles, good anti-stick effect, increased weight of the tape, can keep the elastic band permanently vertical and flat, making sewing smoother and the sewing positioning feeling stronger; TPU elastic bands are widely used in the clothing industry, such as T-shirts, masks, sweaters and other knitted products, bras and women's underwear, swimwear, bathrobe sets, tight-fitting clothing and intimate apparel, active bras and straps, shorts, women's underwear, close-fitting shorts, sweatpants, baby clothes, etc., in places where clothing needs elasticity.
