Dow Corning's Fluorosilicones Offer Processing Options for Effective Connector Seals and Gaskets

Published on 2011-12-08. Author : SpecialChem

Dow Corning Corporation, a global leader in silicone and silicon-based technology and innovation, has a complete selection of proven silicone and fluorosilicone sealing materials for reliable automotive electrical-system connectors. Performance properties and processing characteristics can be tailored to meet application requirements.

"As a solutions specialist, Dow Corning offers many design and processing options with our wide range of innovative materials for effective connector seals and gaskets," said Mitsuhiro Sakamaki, a Dow Corning Global Automotive major market leader. "This includes choices for both fabricated and form-in-place sealing components."

Sakamaki, who oversees the company's initiatives for meeting application challenges in vehicle braking, chassis, body, lighting and electrical systems, added, "Our newest self-lubricating Silastic® brand liquid silicone rubber (LSR) elastomers are designed to improve process efficiency and reduce costs for molded-connector sealing components, such as grommets, weather-pack and mat seals, peripheral seals, and bushings."

Sakamaki noted that heat-resistant silicone choices and fuel-resistant fluorosilicone options offer connector-design flexibility to meet exact application processing and performance requirements:

  • Silastic® High Consistency Rubber (HCR) Elastomers are ready-to-use compounds, easily customized for special needs.
  • Silastic® Liquid Silicone Rubber (LSR) Elastomers balance good mechanical properties with high-volume productivity.
  • Dow Corning® GT Precured Gel Grommets and Sealing Strips provide self-healing mat seals and grommets for high-density connectors.
  • Silastic® Fluorosilicone Rubber (FSR) Elastomers are used for connector seals and gaskets exposed to fuels and oils.
  • Silastic® Fluoro Liquid Silicone Rubber (F-LSR) Elastomers combine fuel resistance with liquid-processing benefits.
  • In addition, a range of Dow Corning® brand silicone and fluorosilicone adhesive/sealants is available for use in manufacturing or service for form-in-place electrical sealing and bonding. Special hot-melt silicone adhesives provide excellent green strength for improving productivity.

    Silastic and Dow Corning connector-sealing solutions can provide strong mechanical sealing against moisture, dust and contaminants. Insulation strength can be maintained over a wider temperature range than many organic elastomers can handle. Application-matched properties can include resistance to harsh conditions, fuels, weathering, aging and compression set.

    "With our many options for reliable electrical-connector seals and gaskets, Dow Corning can collaborate to develop custom solutions to meet specific process, application and performance requirements," Sakamaki said. "As one company with many automotive solutions, we combine innovation and application expertise with total customer service and support."
