Information

 

Hamee Corporation, Japan's leading mobile accessories brand, has introduced a range of custom-made cases made from BASF's Elastollan thermoplastic polyurethane (TPU) for the new iPhone 12 and iPhone 12 Pro.

 

 

The new TPU is used in multi-material hybrid structures, and its UV resistance has been optimized in the new formula to prevent discoloration or yellowing of the phone's case, according to the report. The multi-material construction of the case made from Elastollan provides excellent collision and scratch protection. The smooth, wear-resistant finish improves the experience for iPhone 12 and iPhone 12 Pro owners.

Due to its high durability, yellowing resistance and transparency, Elastollan is ideal for making protective enclosures that are both aesthetically pleasing and practical.  

 

 

 What is TPU?  

TPU(Thermoplastic PolyureThanes) is called Thermoplastic polyurethane elastomer rubber. Mainly divided into polyester type and polyether type points, its hardness range is wide (60HA-85HD), wear resistance, oil resistance, transparent, good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Halogen-free flame retardant TPU can also replace soft PVC to meet the environmental protection requirements in more and more fields. The so-called elastomer refers to the glass temperature is lower than the chamber temperature, the elongation at break >50%, the external force removed after the recovery of good polymer materials. Polyurethane elastomer is a special kind of elastomer, polyurethane elastomer hardness range is very wide, the performance range is very wide, so polyurethane elastomer is a kind of polymer material between rubber and plastic. It can be heated and plasticized, with little or no chemical crosslinking. The molecules are basically linear, but there is some physical crosslinking. This type of polyurethane is called TPU.  

 

 

The main features of TPU are:

 

Widespread hardness range: products with different hardness can be obtained by changing the ratio of each reaction component of TPU, and with the increase of hardness, the products still maintain good elasticity and wear resistance.

High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption properties.

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 Celsius.

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, polymer alloys with complementary properties can be obtained by processing TPU together with some polymer materials.

 

TPU, as an elastomer, is a material between rubber and plastic, which can be seen from its rigidity, which can be measured by the modulus of elasticity. The elastic modulus of rubber is usually 1~10Mpa, TPU is 10~1000Mpa, and plastic (nylon, ABS, PC, POM) is 1000~10000Mpa. TPU has A wide hardness range from Shore A 60 to Shore D 80 and is highly elastic across the entire hardness range. TPU is flexible over a wide temperature range of -40~120 ° C without the need for plasticizers. TPU has good resistance to oils (mineral oils, animal and vegetable oils and lubricants) and many solvents; TPU also has good weather resistance and excellent performance of high energy ray resistance. Well-known wear resistance, tear resistance, flexion strength are excellent; High tensile strength, high elongation, and low permanent deformation rate of long-term compression are the obvious advantages of TPU.

 

 

新保护套的未来市场

Polyurethane is a new kind of organic polymer material, known as the "fifth plastic", because of its excellent performance and has been widely used in many fields of national economy. There are many kinds of polyurethane products, polyurethane elastomer is an important variety of polyurethane, its current consumption accounts for nearly 10% of the total consumption of polyurethane. Polyurethane elastomer is a series of elastomer materials with more carboxate groups on the backbone chain of polymerization. It is a kind of polymer material that can be recovered well after the elimination of external force applied to it.

 

TPU industry is a branch of the polyurethane industry, located in the downstream of the entire chemical industry chain, closer to the end consumer market.

 

Polyurethane elastomer can be used to manufacture all kinds of rubber wheels, conveyor belts, water and pressure resistant rubber hoses, sealing strips and rings, cable sheath and various films, etc. The products are widely used in steel, paper making, mining, machinery, printing and other industries. Polyurethane elastomers can be compounded with polyvinyl chloride, polyethylene, ABS plastic, carbon fiber, etc., to reduce costs and improve performance. Polyurethane elastomers can also be modified by adding some organic fillers to highlight and strengthen some of the superior properties, while overcoming some of the shortcomings of polyurethane elastomers to meet special needs. China is currently the world's largest producer, consumer and exporter of PU elastomers, accounting for about 45% of the world's PU output.

 

"The newly launched Higher smartphone accessory is the result of our continued innovation. The transparent phone case is classic in design, but it offers quality and value to consumers. It is made of excellent materials that are durable and aesthetically pleasing, "said Takuro Watabe, head of Hamee's quality control group.

 

Minli Zhao, Vice President of Consumer Industries, Performance Materials Asia Pacific, BASF, added: "We are delighted to have Hamee in partnership to launch the new iPhone 12 case. "Elastollan offers leading quality and design freedom while keeping abreast of today's latest mobile trends."
