What are the inspection standards of silicone products?

Silicone products are more and more widely used in modern industry and daily life, and its quality is directly related to the safety and experience of users. Therefore, it is important to understand the inspection standards of silicone products.

1. Overview of silicone products
Silicone products are a variety of products made of silicone, with environmental protection, soft, safe and non-toxic characteristics. They are widely used in medical, electronic, home, maternal and child supplies and other fields. The inspection standards of silicone products are designed to ensure product quality, meet the requirements of use and safety.

2. Inspection standards of silicone products
The inspection standards of silicone products mainly include the following aspects:
HG/T2765 series standards: including HG/T2765.1-1996 "Silica gel fine pore float", HG/T2765.2-2005 "coarse pore silica gel", etc., the physical and chemical properties of silica gel are specified in detail.
GB4806.11-2016 standard: This is the safety standard for food contact materials, which specifies the food-grade safety of silicone products.

The following is the specific test standard content:
Appearance quality: including color, gloss, surface smoothness, etc., to meet the technical requirements of the corresponding product.
Dimensional deviation: Check the dimensional accuracy of the product to ensure that the product size meets the design requirements.
Physical properties: including tensile strength, tearing strength, hardness, elongation and other indicators of the test.
Chemical properties: including high temperature resistance, low temperature resistance, chemical resistance, aging resistance and other properties of the test.
Health performance: The health indicators of silicone products are tested to ensure that the product is harmless to the human body.

3. Inspection process
The inspection process of silicone products usually includes the following steps:
Sample preparation: Random samples are taken from the production batch for pre-inspection preparation.
Appearance inspection: Visual inspection of the appearance of the sample, including color, appearance defects, etc.
Performance test: According to product standards and requirements, the corresponding physical and chemical properties of the sample test.
Health indicators testing: food contact silicone products, health indicators testing.
Inspection result judgment: According to the inspection result, determine whether the product is qualified.
