The standardization and certification system of fluorosilicone (fluorosilicone rubber) is the key to ensuring its product quality, safety and performance. The following is a detailed analysis of the standardization and certification system of fluorosilicone:


1. Standardization of fluorosilicone
International and national standards:
The standardization of fluorosilicone is usually carried out by the International Organization for Standardization (ISO) and national standardization agencies. For example, standards such as ISO 1629 and ISO 1628 specify the physical and chemical properties of fluorosilicone rubber.
In China, there are also corresponding national standards or industry standards to regulate fluorosilicone, such as HG/T 5753-2020 "Room temperature curing (vulcanization) fluorosilicone sealant".
Composition and performance requirements:
The standardization of fluorosilicone covers many aspects such as its composition, physical properties and chemical properties.
Composition requirements usually specify the content range and requirements of fluorosilicone polymers, fillers, additives and other components in fluorosilicone to ensure the stability and consistency of product performance.
Physical performance requirements include hardness, tensile strength, elongation at break, tear strength and other indicators, which determine the wear resistance and tensile resistance of fluorosilicone in practical applications.
Chemical performance requirements focus on the chemical medium resistance and high temperature resistance of fluorosilicone to ensure that it can maintain stable performance in various harsh environments.
Classification and naming:
Fluorosilicone is usually classified and named according to its hardness, use, etc. For example, addition-type liquid fluorosilicone rubber can be divided into different grades such as 30, 40, 50, and 60 according to hardness.

2. Certification system of fluorosilicone
Certification by third-party testing agencies:
Fluorosilicone products usually need to be certified by third-party testing agencies to ensure that they comply with relevant standards and regulations. These third-party testing agencies usually have qualifications such as CMA (China Metrology Certification) and CNAS (China National Accreditation Service for Conformity Assessment).
Certification items may include appearance, hardness, tensile strength, elongation at break, oil resistance test, solvent resistance, high temperature stability, etc.
Industry Certification and Standard Conformity Statement:
In addition to certification by a third-party testing agency, fluorosilicone products may also need to pass industry certification or conform to industry-specific standard statements. For example, in the automotive industry, fluorosilicone products may need to comply with specific standards and specifications of the automotive industry.
Manufacturers usually provide standard conformity statements or certification certificates to prove that their products comply with relevant standards and regulations.
Quality Management System Certification:
In order to ensure the quality and consistency of fluorosilicone products, manufacturers usually establish a quality management system and obtain quality management system certifications such as ISO 9001. These certifications demonstrate the manufacturer's ability and commitment to quality management.

3. The significance of fluorosilicone standardization and certification system
Guarantee product quality: Through the standardization and certification system, it can be ensured that the quality and performance of fluorosilicone products comply with relevant standards and regulations, thereby improving the reliability and safety of products.
Promote technological innovation: The standardization and certification system can promote the continuous innovation and development of fluorosilicone technology, and provide the industry with new solutions and driving forces for progress.
Enhance market competitiveness: Fluorosilicone products that have obtained relevant certifications and conformity statements are more likely to gain customer trust and recognition, thereby gaining greater competitive advantages in the market.

In summary, the standardization and certification system of fluorosilicone is the key to ensuring the quality, safety and performance of its products. Manufacturers should actively participate in standardization work and obtain relevant certifications and declarations to improve the market competitiveness of products and meet customer needs.
