When it comes to showering, we often focus on the showerhead itself, the water pressure, or the temperature control. However, one crucial component that often goes unnoticed is the shower hose. Flexible shower hoses are essential components of any shower system, they play a vital role in our daily bathing routine, providing flexibility and convenience in directing water flow during showering that enhances the overall showering experience. These hoses consist of an inner hose and an outer layer with a nylon fiber in middle, both made from specific materials that contribute to their flexibility, durability, and performance.
Let’s delve into the world of shower hoses, exploring their versatility, functionality, and the various benefits they bring to our bathrooms.

Materials for Flexible Shower Hoses:

The outer layer of flexible shower hoses is designed to protect the inner hose and provide additional durability and flexibility. Here are some commonly used materials for the outer layer:

1.Stainless Steel: Stainless steel is a popular choice for the outer layer of flexible shower hoses. Stainless steel braided hoses offer exceptional durability, resistance to rust and corrosion, and high-pressure capabilities. The stainless steel braid adds strength and protection to the inner hose while maintaining flexibility.

2.PVC (Polyvinyl Chloride): PVC is also used as an outer layer material for flexible shower hoses. PVC-coated hoses offer additional protection and durability, preventing rust, corrosion, and damage. The PVC coating enhances the aesthetic appeal of the hose and provides a smooth surface.

3.Brass Shower Hoses:
Brass shower hoses are renowned for their durability and sturdiness. Constructed from solid brass materials, these hoses are built to withstand heavy use and are resistant to corrosion. Brass hoses often feature a chrome or brushed nickel finish, providing a visually appealing and luxurious touch to your shower area. The inner tubing of brass hoses is typically reinforced to prevent kinking, ensuring a consistent water flow.

4.Plastic: Some flexible shower hoses feature an outer layer made of plastic materials such as polypropylene or nylon. These plastic layers offer added protection against corrosion, impact, and wear while maintaining flexibility.

Materials for Inner Hoses:

The inner hose of a flexible shower hose plays a crucial role in determining its flexibility, strength, and resistance to water and pressure. Here are some commonly used materials for the inner hose:

1.EPDM (Ethylene Propylene Diene Monomer): EPDM rubber is a popular choice for the inner hose of flexible shower hoses. It offers excellent resistance to heat, water, and steam, making it suitable for high-temperature shower systems. EPDM rubber provides flexibility, durability, and resistance to cracking or deteriorating over time.

2.PEX (Cross-linked Polyethylene): PEX is a thermoplastic material known for its flexibility, durability, and resistance to high temperatures and pressure. PEX inner hoses are commonly used in plumbing applications, including shower hoses, due to their excellent performance and longevity.

3.PVC (Polyvinyl Chloride): PVC is a widely used material for the inner hose of flexible shower hoses. PVC inner hoses offer good flexibility, affordability, and resistance to corrosion. They are lightweight and easy to handle, making them suitable for standard shower setups.

4.TPU (Thermoplastic Polyurethane elastomer): TPU is known for its exceptional lightweight, durability, and resistance to wear and tear. TPU shower hoses are a relatively new addition to the market, The TPU material provides a good balance between rigidity and flexibility, ensuring that the hose can be easily moved and directed without kinking or tangling. They are resistant to cracking, breaking, and leaks, ensuring a longer lifespan compared to other materials.

While TPU is a durable and versatile material, it is not immune to potential defects. However, there are instances where adjusting the hardness and improving the elasticity of TPU can offer additional benefits for Flexible Shower Hoses, and other specific applications.

    5.Si-TPV Thermoplastic Elastomer: Si-TPV (vulcanizate thermoplastic Silicone-based elastomers), or silicone thermoplastic vulcanizate, is a Soft material targeted for flexible pipe hose that combines rubber's flexibility with the processing advantages of thermoplastics. Si-TPV is low-odor, plasticizer-free, and exhibits easy bonding to various substrates. including PC, ABS, PC/ABS, TPU, PA6, and similar polar materials. Si-TPV is particularly well-suited for flexible pipe hose connectors in bathroom and water systems, offering a super soft and environmentally friendly solution.

    1. Adding SILIKE Si-TPV improves the surface smoothness of thermoplastic polyurethanes(TPU), thereby enhancing their scratch and abrasion resistance. Moreover, surfaces become more resistant to dust adsorption, a non-tacky feel that resists dirt. 2. Adding more than 10% Si-TPV to a thermoplastic polyurethane elastomer balance between its hardness and mechanical properties, rendering it softer and more elastic. it contributes TPU manufacturers to creating high-quality, more resilient, efficient, and sustainable fast-charging pile cables. 3. Add Si-TPV into TPU, Si-TPV improves the soft touch feeling of the EV Charging cable, achieving a visual of the surface matt effect, and durability.


Si-TPV is an innovative silicone-based additive modifier, It can be compounded to various elastomers, such as TPE, TPU, and more to reduce hardness, and increase the flexibility, elasticity, and durability of these plastics.
While a highlight of plastic products made with blends of TPU and the Si-TPV additive is a silky-soft surface with a dry feel. This is precisely the type of surface that end users expect of products that they frequently touch or wear. With these features, it has extended the range of its applications.
Furthermore, if you wanted to create the better-performing hose ever in terms of flexibility, rolling resistance, and sustainability or one that enhances the aesthetics of the bathroom, Si-TPV reinforced hoses are a superior option.
The shower head hose is made of soft skin-friendly SI-TPV material inner core for durability, high pressure, and temp resistance, and chemical resistance, lightweight, flexible, and has no kinking, ensuring long-lasting performance and a comfortable showering experience.
The waterproof Si-TPV and its easy-to-clean properties add to their appeal.
