“LSR Solutions for Compatibility with Fire Retardant Plastics” Webinar by RDAbbott (June 29)
May 24, 2023
Why You Should Attend
Self-lubricating LSRs are the material of choice for sealing fire-rated plastic automotive connectors. Recently, however, there have been an increasing number of reports of unexpected seal failure. Researchers theorize that phosphorous-containing flame retardants in plastic connectors may undergo thermal degradation and migration to the silicone elastomer, causing random polydimethylsiloxane (PDMS) chain scission and crosslinking in a compressed state.
In response to this situation, Dow has developed SILASTIC™ 921X LSR Series. This new portfolio of engineering elastomers support the use of FR-rated plastic materials for automotive connectors such as V0-rated PA6, PA66, and PBT. When in direct contact with FR-rated engineering plastics, SILASTIC™ 921X LSR Series provide both environmental and electrical isolation.
As compared to competitive products, the key benefits of Dow’s new LSRs are:
- Long-term compression set and sealing force retention with halogen-free fire retardant (HFFR) V0-rated PA6, PA66, and PBT thermoplastics
- Low compression set without post-cure
- The same performance and processing expectations as a conventional LSR
- Available in a broad range of hardness, from 20 to 50 durometers, plus Shore A
