High-temperature resistant silicone is a category of silicone products with special properties. Below is a detailed introduction to it:

I. Definition and Composition

High-temperature resistant silicone, as the name implies, is a silicone material that maintains stable performance in high-temperature environments. It is typically composed of chain polymer compounds formed by alternating silicon and oxygen atoms, which endow it with excellent high-temperature resistance.

II. Main Features

Withstanding high and low temperature shocks: High-temperature silicone features a broad operating temperature range, with the high-temperature resistance of regular silicone typically between 200~300 degrees Celsius. Some special formulations of silicone can withstand temperatures around 350 degrees Celsius within a short period (such as two hours).

Rapid vulcanization: Vulcanization is a crucial step in the production of silicone products. High-temperature-resistant silicone can be quickly vulcanized through heating or pressure, forming a stable three-dimensional network structure.

Low odor: Emissions during the sulfurization process are harmless to humans.

Superior adhesion: Adheres to various substrates without the need for primer.

Excellent Insulation: High-temperature-resistant silicone features excellent electrical insulation properties.

Chemical Stability: Excellent ozone resistance and chemical erosion resistance.

High mechanical strength: Possesses sufficient mechanical strength to meet various application requirements.

Resistance to aging: Capable of withstanding the erosion of environmental factors like ultraviolet rays, extending service life.

In addition, high-temperature-resistant silicone boasts excellent transparency (such as high-temperature-resistant liquid silicone), tear resistance, resilience, resistance to yellowing, thermal stability, water resistance, and breathability.

Section 3: Production Process Flow

The production process of high-temperature silicone products mainly includes the following steps:

Silicone raw material selection: Choose high-quality silicone raw materials to ensure the product has excellent high-temperature resistance.

Formula Adjustment: Adjust the components in the formula, such as fillers, cross-linking agents, antioxidants, etc., based on the product's performance requirements.

Mixing: Thoroughly mix the silicone raw material with various additives as per the formula to ensure even distribution of ingredients. The mixed silicone should possess good fluidity and plasticity.

Forming: Products are formed using methods such as pressing, injection molding, or extrusion, based on their shape and size. Temperature, pressure, and time must be controlled during the forming process to ensure product quality.

Sulfurization: A process where silicone molecules are cross-linked by heating or pressure, creating a three-dimensional network structure, significantly improving the physical and chemical properties of silicone.

Post-processing: Includes deburring, cleaning, and drying to enhance the appearance and performance of the product.

Inspection and Packaging: Conduct various performance tests on vulcanized products to ensure compliance with standard requirements. Package the qualified products and prepare for shipment.

Section 4: Application Fields

High-temperature resistant silicone, with its unique properties, is widely used in various fields:

Industrial Sector: Used for sealing, bonding, lubricating, and surface protection, such as engine sealing and lubrication in automobiles, encapsulation and protection of electronic components, etc.

Medical Field: Used for sealing, lubricating, and surface treatment of medical devices, ensuring stability and durability during high-temperature sterilization or disinfection processes.

Food Processing Industry: Used for sealing, lubrication, and surface treatment of food processing equipment to ensure stability and hygiene during the food processing process.

Energy Sector: Widespread applications in nuclear, solar, and fossil energy areas, such as the sealing and lubrication of nuclear reactors, encapsulation and protection of solar cells, etc.

Additionally, high-temperature-resistant silicone is widely used in the fields of aerospace, electronics and electrical, mechanical manufacturing, construction materials, petrochemicals, and more.
