About Conductive Silicone Sealing Ring

Conductive silicone sealing ring mainly refers to silicone sealing ring, which has excellent conductivity. Usually, rubber products are conductive because carbon black is added to the raw material when adding auxiliary materials. Carbon black is conductive, but the conductive current also has strengths and weaknesses. Silicone conductive O-rings have excellent electrical conductivity. Product models include conductive silicone O-ring, conductive silicone U-ring, conductive silicone V-ring, conductive silicone Y-ring, conductive silicone rectangular sealing ring, conductive silicone sealing ring, conductive silicone flat gasket sealing ring, etc.

Introduction

According to the type and processing method of the basic rubber, high-temperature vulcanized conductive silicone rubber and room-temperature vulcanized conductive silicone rubber can be made, as well as pressure-sensitive conductive silicone rubber, anisotropic conductive silicone rubber and low-temperature conductive silicone rubber.

Compared with general conductive rubber, conductive silicone rubber has the advantages of small volume resistivity, low hardness, high and low temperature resistance (-60~200℃), anti-aging, good processing and manufacturing performance, and is particularly suitable for manufacturing.

In recent years, with the rapid development of electronic technology and instrument industry, the improvement and development of conductive silicone sealing ring have been promoted, and many new processes and new varieties have emerged. For example, during the vulcanization process, normal-pressure hot air thinning of conductive silica gel occurs instead of traditional high-temperature addition vulcanization (peroxide thinning). In terms of product performance, high tear-resistant conductive silica gel appears, and in Silicone rubber has a metal powder added to it and the pressure-receiving part is opened, while uninsulated pressure-sensitive silicone rubber uses pressure. Therefore, the application of conductive silicone sealing ring is becoming more and more widespread.

Advantages

A series of conductive rubber materials based on silicone rubber, with excellent shielding and sealing properties, meeting harsh application environments. The flame retardant level complies with UL94 V0, RoHS, and REACH standard certification. It is an environmentally friendly material with high cost performance.

The conductive rubber sealing ring is made of conductive rubber material. It has good elasticity, minimal deformation under extrusion, good sealing performance, and can ensure long-term sealing without deformation. It is conductive, wear-resistant, corrosion-resistant, aging-resistant, and durable. Linde Polymer can Customized according to customer’s requirements.

Application

At present, conductive silicone sealing ring have been widely used in liquid crystal displays (LCDs), light-emitting diodes (LEDs), integrated circuit (IC) chips, printed circuit board assemblies (PCBA), lattice blocks, ceramic capacitors, membrane switches, smart cards, radio frequency The packaging and bonding of electronic components and components such as identification have a tendency to gradually replace traditional soldering.

Certification Standards

1. ISO 9001: It is an international standard for quality management systems. Relevant companies need to follow quality management standards, including the manufacturing and inspection of products such as conductive silicone sealing ring.

2. ISO 13485: This standard specifies the requirements for quality management systems in the medical device industry. If conductive silicone sealing ring are used in the medical field, ISO 13485 must be observed.

3. UL 94: This is the flammability standard issued by the U.S. Insurance Laboratory (UL). Used to evaluate the flammability of plastic materials including rubber such as silicone, while conductive silicone sealing ring need to meet specific flammability requirements to meet safety standards.

4. RoHS: It is about the restriction standard of hazardous substances. This restricts the use of certain hazardous substances in electrical and electronic equipment. For example, conductive silicone sealing ring used in electronic equipment need to comply with RoHS regulatory standards.

5. REACH (Registration, Evaluation, Authorization and Restriction of Chemicals): This standard applies to the registration, evaluation and authorization of chemical substances in the EU. If the conductive silicone sealing ring is sold in the EU, it needs to comply with the regulatory requirements of REACH.
