실리콘 유형 및 차이

Silicone is an incredibly versatile material that plays a crucial role in many industries. Thanks to its flexibility, heat resistance, chemical stability, 그리고 내구성, it is widely used in everything from medical devices to industrial equipment and everyday consumer products. 하지만, not all silicone is the same—different types are specially designed to meet specific needs, each offering unique benefits.

In this article, we’ll take a closer look at four main types of silicone rubber, explaining their composition, key features, and common applications. We’ll also compare their strengths and limitations, helping you understand which type is best suited for different purposes.

4 Types of Silicone and Their Distinctions

Type 1: 액체 실리콘고무 (LSR)

액체 실리콘고무 (LSR) is a two-part platinum-cured silicone that remains in liquid form before being processed. Its excellent flow properties make it ideal for injection molding, enabling the production of highly detailed and precise parts. LSR is widely recognized for its biocompatibility, making it a preferred choice for medical and food-grade applications. Unlike traditional silicone rubbers, LSR cures without releasing byproducts, ensuring purity and safety.

Key Features:

• High precision molding capability
• Excellent thermal stability (-50°C to 250°C)
• Resistant to UV radiation and harsh environmental conditions
• Biocompatible and non-toxic

일반적인 응용:

• Medical implants and tubing
• Baby products such as pacifiers and bottle nipples
• High-performance gaskets and seals
• Consumer electronics and wearables

Type 2: 높은 일관성 고무 (HCR)

높은 일관성 고무 (HCR), also referred to as solid silicone rubber or gum stock, 더 두껍습니다, putty-like consistency. It consists of high molecular weight polysiloxane chains and can be processed through compression or extrusion molding. HCR is highly durable and can withstand extreme temperatures, making it suitable for both industrial and consumer applications. It is typically cured using either peroxide or platinum-based curing systems, with the latter offering a cleaner curing process.

Key Features:

• Exceptional mechanical strength and flexibility
• Suitable for high-temperature applications (up to 300°C)
• Can be customized with fillers for enhanced properties
• Long-term durability and stability

일반적인 응용:

• Automotive engine components
• Medical long-term implants
• Electrical insulation materials
• Consumer products such as cookware and bakeware

Type 3: Room Temperature Vulcanized Silicone (RTV)

Room Temperature Vulcanized (RTV) silicone is a type of silicone rubber that cures at ambient temperatures without the need for additional heat. RTV silicones come in two primary forms: one-component (RTV-1) and two-component (RTV-2). RTV-1 cures by reacting with moisture in the air, while RTV-2 requires mixing before use. Due to their ease of application and versatility, RTV silicones are widely used in sealing, 본딩, and molding applications.

Key Features:

• Cures at room temperature without additional heat
• Excellent adhesion to various substrates
• Offers resistance to water, 화학, and temperature extremes
• Available in flexible, semi-rigid, and rigid forms

일반적인 응용:

• Adhesives and sealants for construction and automotive industries
• Mold-making and prototyping
• Electrical potting and insulation
• DIY and household repair products

Type 4: 플루오로실리콘 (FVMQ)

Fluorosilicone is a specialized type of silicone rubber that contains fluorinated side groups, enhancing its resistance to oils, 연료, and harsh chemicals. While it retains many of the advantageous properties of standard silicone, such as flexibility and temperature stability, it offers superior chemical resistance, making it indispensable in demanding industrial applications.

Key Features:

• Excellent resistance to fuels, 유화, 및 용제
• High-temperature performance (-60°C to 250°C)
• Maintains flexibility and durability in harsh environments
• More expensive than conventional silicone due to its enhanced properties

일반적인 응용:

• Aerospace and aviation fuel systems
• Automotive gaskets and O-rings
• Industrial seals and hoses
• Specialty coatings for chemical resistance
