Recently, the materials technology department of Aluda collaborated with a fluid control component manufacturer to complete the project verification of replacing the fluorosilicone rubber of a certain foreign brand with Aluda's high-rebound fluorosilicone (ALUDA FVMQ) for the valve core of the one-way valve. 

I. Project Background 

This one-way valve has been using foreign brand fluorosilicone materials for a long time, which has led to problems such as long supply chain and fluctuating costs. The customer has requested to find a domestic alternative solution with equivalent performance and faster response, while maintaining the original assembly process. 

II. Alternative Solutions and Testing Methods 

Alternative material: Aluda High Resilience Fluorosilicone (ALUDA FVMQ), customized hardness and resilience rate formula 

Reference material: A certain brand of fluorosilicone rubber from Dow Chemical of the United States 

Test basis: The technical agreement mutually agreed upon by both parties, and in accordance with the dynamic test standards for one-way valves in the industry. 

Test conditions: Impact frequency 250 times per minute, stroke 2 to 3 mm, continuous testing for 8 hours per day 

Core test items: Frequency of opening and closing fatigue, condition of sealing surfaces, and damage status of components 

III. Verification Results (Based on Customer Test Report) 

Under the same testing conditions: 

Total opening and closing times: 16,480,000 times 

Valve core condition: Sealing surface is intact, engraved surface has slight wear, and the umbrella handle area shows no cracks. 

Conclusion: The one-way valve shows no obvious damage during the opening and closing process. 

IV. Project Status and Conclusion 

Current status: This alternative solution has passed the internal technical review of the client and completed the verification of the opening and closing fatigue test. 

Conclusion: The Aludra high resilience fluorosilicone in this one-way valve application passed a 16.48 million cycle opening and closing fatigue test. It can be regarded as a reliable alternative to the fluorosilicone of this foreign brand. 

V. Regarding Aludra 

Aluida is a specialized manufacturer of fluororubber (FKM), fluorosilicone (FVMQ), and hydrogenated nitrile (HNBR) materials. Based on real application scenarios and test data, it provides customers with verifiable and traceable alternative and customized solutions. 

Note: All the conclusions in this article are based on the test results under the specific conditions of this project. The actual application effect may vary depending on the working conditions, and targeted verification is recommended.
