Portable Pressure Shower Materials

- Oct 03, 2019-

Portable pressure bag is a very popular outdoor shower product in recent years.

 It only needs to put water into the barrel body, foot on the pump, and can directly take a bath, wash the car, water flowers, wash vegetables, etc. It is very convenient to use, especially in the field, the frequency of use is very frequent.

 Portable pressure bags are currently made of two different materials.

 One material of the pressure shower bag outdoor is PVC tarpaulin cloth, which is dirty resistant, firm, environmentally friendly, price-friendly, and is more acceptable to the public as a product.


Another material of the outdoor pressure shower bag is TPU. Compared with PVC mesh cloth, TPU is more environmentally friendly, has longer service life and smoother surface. It is the first choice for high-end customers in Europe and America.


 So, what is TPU?


TPU (Thermoplastic polyurethanes) is called thermoplastic polyurethane elastomer rubber. It can be divided into polyester type and polyether type. Its hardness range is wide (60HA-85HD), wear resistance, oil resistance, transparency and good elasticity are widely used in daily necessities, sports 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 polymer material with good resilience after the removal of external force, whose glass transition temperature is lower than room temperature and elongation at break is more than 50%. Polyurethane elastomer is a special kind of elastomer. The hardness range of polyurethane elastomer is very wide and its performance range is very wide. Therefore, polyurethane elastomer is a kind of macromolecule material between rubber and plastics.


Thermally plasticizable, with little or no cross-linking in chemical structure, its molecules are basically linear, but there are some physical cross-linking. This type of polyurethane is called TPU.
