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.

    The modification of TPU surfaces is of outstanding importance aiming to develop materials that could maximize the material's performance in specific applications. But first, we need to know Understanding TPU Hardness and Elasticity, TPU hardness refers to the material's resistance to indentation or deformation under pressure. Higher hardness values indicate a more rigid material, while lower values indicate greater flexibility.
    Elasticity, on the other hand, refers to the ability of a material to deform under stress and return to its original shape upon removal of the stress. A higher elasticity implies improved flexibility and resilience.
    In recent years, the incorporation of silicone additives into TPU formulations has gained attention for achieving these desired modifications, it plays a vital role in improving the processing characteristics and surface quality of TPU, without detrimentally affecting the bulk properties.
    This occurs due to silicone molecules and compatibility with the TPU matrix, it acts as a softening agent&lubricant within the TPU structure, allowing for easier chain movement and decreased intermolecular forces. that results in a softer and more flexible elasticity TPU with reduced hardness values.
    In addition, it acts as a processing aid, reducing friction and enabling smoother melt flow. This facilitates easier processing and extrusion of TPU, resulting in enhanced productivity and reduced manufacturing costs.

    Currently, according to market feedback, In the field of TPU application, Genioplast Pellet 345 has gained recognition as a valuable silicone additive in TPU. The new additive is readily incorporated into TPUs and has fewer undesirable secondary effects than conventional silicone products. This silicone additive has extended the range of applications for thermoplastic polyurethanes. There is considerable demand for consumer goods, automotive, medical devices, water pipe&hoses, sports equipment handle grips tools, and more sectors for molded TPU parts that have a pleasant comfortable feel and retain their looks upon protracted use.
    Herein, Silike’s Si-TPV silicone additives offer equal performance to its, with a reasonable price.
    All tests have demonstrated that Si-TPV as silicone additive alternatives are viable safe, and eco-friendly in TPU applications and polymers, it is a worthwhile initiative to try!
    Since this silicone-based additive achieves long-term surface smoothness and good hand-touch feeling, reduces flow marks and surface roughness, enhancing their scratch and abrasion resistance. reduce the hardness with no negative effect on mechanical properties, better-aging resistance, yellow resistance, stain resistance, or a visual of the surface matt effect, This leads to enhanced aesthetic appeal of TPU components or finished products.
    SILIKE Si-TPV Series thermoplastic elastomer is a dynamic vulcanized thermoplastic silicone-based elastomer made by special compatible technology to help silicone rubber dispersed in TPO evenly as 2~3 micron particles under a microscope. Those unique materials combine the strength, toughness, and abrasion resistance of any thermoplastic elastomer with desirable properties of silicone: softness, silky feel, UV light, and chemical resistance which can be recycled and reused in traditional manufacturing processes.


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.
