Today I will introduce a new type of game to you.
This game is called the zorb ball game. the zorb balls are made of PVC or TPU.
What material is TPU? Thermoplastic polyurethane elastomer, referred to as TPU, also known as PU thermoplastic, is a line fee block copolymer composed of oligomer diol soft segment and diisocyanate-chain extender hard segment.
From the perspective of chemical structure, TPU is a block copolymer, which is mainly divided into the polyester type and polyether type. The polyester type has good tensile and flexural properties, high-temperature resistance, and high wear resistance, while the polyether type has Relatively low-temperature resistance, hydrolysis resistance, high strength, and resilience.
Thermoplastic polyurethane elastomers can be synthesized by prepolymer method, one-step method, and semi-prepolymer method. The one-step process is simple, the production efficiency is high, the performance of the elastomer is better, and the one-step method is generally used in industrial production. TPU production processes include batch bulk method (also known as melting method), twin-screw bulk continuous method, solution polymerization method, etc.
Disadvantage of TPU
Large endogenous heat and general high-temperature resistance. The normal operating temperature range is -40~120℃. If it needs to be used for a long time under high-frequency oscillation conditions or high-temperature conditions, corresponding modification measures must be taken in structural design or formula.
Where to buy
You can go to Kameymall to buy zorb balls. You will have a very nice experience.
