FOREVER High-Performance Water-Contact Material for Water Diversion Valves

High-Performance Water-Contact Material: FOREVER Redefines the Quality Standard of Water Diversion Valves

NSF WRAS.png

In the bathroom industry, the water diversion valve is a core component that regulates water flow and temperature, acting like the "heart" of faucets and shower heads. Its performance directly affects the service life of bathroom products and user satisfaction. As an innovative brand deeply engaged in the bathroom material field, FOREVER fully understands the decisive role of water diversion valve materials in product experience. Targeting industry pain points, we have developed exclusive high-performance water-contact materials, injecting new vitality into the industry's quality upgrade.

Water diversion valves are long-term exposed to humid environments and direct water contact, requiring extremely high standards for material water resistance, stability, and safety. However, traditional materials for water diversion valves have inherent performance limitations, with prominent application pain points, which also became the core opportunity for FOREVER to develop innovative materials:

Industry Pain Points of Traditional Water Diversion Valves

Metal Water Diversion Valves

Made of stainless steel, zinc-copper alloy, and other metal materials, they can withstand corrosion in humid environments to a certain extent and extend service life. However, in long-term water contact scenarios, heavy metals are prone to leaching, which directly endangers human health, contradicts consumers' growing emphasis on health and environmental protection, and fails to meet FOREVER's strict standards for product safety.

Ordinary Plastic Water Diversion Valves

The "plastic instead of steel" approach avoids the risk of heavy metal leaching and simplifies the processing flow. Nevertheless, residual polymer monomers, solvents, additives, and other components in ordinary plastics may still affect drinking water safety. In addition, ordinary plastics are prone to deformation and softening after long-term immersion in water, failing to meet the high standards for material durability and stability required by bathroom products, and cannot adapt to FOREVER's core demand of providing long-term and reliable products for customers.

Therefore, developing a material with low migration rate for drinking water contact, resistance to water vapor erosion, and stable performance under long-term immersion has become a core development demand in the bathroom industry. Seizing the opportunity, FOREVER relies on its own R&D capabilities to break through the limitations of traditional materials and create exclusive high-performance water-contact materials. With advanced technology and outstanding performance, it has become the preferred choice for many bathroom manufacturers to upgrade their products.

Core Advantages: Dual Breakthroughs in Safety and Performance of FOREVER Materials

1. Authoritative Certifications: FOREVER Builds a Solid Line of Defense for Water Safety

Adhering to the R&D philosophy of "health first", FOREVER's high-performance water-contact material has passed the US NSF61 certification and UK WRAS BS6920 certification, with a maximum service temperature of 85℃ (82±2℃ under NSF standard, 85℃ under WRAS standard). It strictly meets rigorous requirements such as low migration rate, odorlessness, and no promotion of algae growth, ensuring safe and reliable long-term contact with drinking water, safeguarding users' water health from the source, and demonstrating FOREVER's ultimate pursuit of product safety.

The material has a wide range of applications, covering various water-contact products such as showerheads, coffee machines, water purifiers, faucets and water purification systems, water meter components, toilets, floor scrubbers, and joints/pathway parts. It can perfectly adapt to households, hotels, hospitals, and other places, providing multi-scenario material solutions for FOREVER's cooperative customers.

2. High-Performance Upgrade: FOREVER Empowers Product Durability Breakthrough

On the basis of adhering to the bottom line of safety, FOREVER's high-performance water-contact material takes high fluidity as its core advantage, endowing products with excellent surface quality, low water absorption, and dimensional stability. At the same time, it can maintain outstanding mechanical properties even in high-temperature environments of 95℃, extending the service life of water diversion valves and various water-contact products from the material level.

Tested by FOREVER's professional laboratory, after 250 hours of immersion in 95℃ hot water, the material's performance tends to be stable without significant attenuation. When applied to shower water diversion valves, it can withstand a water pressure of 35 kg at room temperature and does not crack after freezing and thawing at -5℃. When used in floor heating water diversion valves, it has a smooth surface without floating fibers, can withstand a water pressure of 3.3MPa at room temperature without cracking, and has a thread torque greater than 35N.m, with performance far exceeding industry conventional standards.

3. Excellent Processability: FOREVER Adapts to Diverse Production Needs

Optimized specifically for injection molding, FOREVER's high-performance water-contact material fully considers the actual needs of the production end, can easily form various complex-shaped water diversion valve components, and simplifies the production process for cooperative manufacturers. It has a reasonable processing temperature range, with specific parameters as follows, helping manufacturers improve production efficiency and reduce costs.
