Sealing Compound Housing and Electronic Control Device
The disclosure relates to a sealing compound that can be applied wet and is curable to form an elastic seal. The sealing compound contains a matrix material and a corrosion-inhibiting additive. In addition, a housing having the elastic seal as well as an electronic control device with the housing are disclosed.
Seal ring
A nickel-based alloy for forming a seal ring is disclosed. Such seal rings, in use may be static or rotating and may be used in a variety of applications, such as in wheel assemblies of machines. Using the alloy, the seal ring may be manufactured using a centrifugal casting method. The disclosed alloy includes a chromium content greater than at least 13.5% by weight, a boron content less than 3% by weight, a carbon content less than 2% by weight, and nickel content greater than 70% by weight. The nickel alloy may have a carbon plus boron atomic content divided by chromium atomic content less than 1.1. This alloy allows for the rapid cooling of centrifugal casting while maintaining a grain morphology suitable for relatively low leakage and relatively high durability. When the alloy is formulated, the seal ring is formed by centrifugal casting.
LASER-MARKABLE SEALING COMPOUNDS WITH OXYGEN ABSORBERS
Receptacle closure made of metal, with a sealing insert that is arranged in the receptacle closure in such a way that it comes into contact with the mouth of the receptacle when the receptacle closure is positioned on the receptacle, wherein the sealing insert contains or is made from a sealing compound that includes at least 10% by weight, preferably at least 40% by weight LDPE relative to the total weight of the sealing compound, in particular with butene, hexene or octene as comonomer besides contents of LLDPE and/or OBC and a content of more than 2% by weight of at least one oxygen-absorbing compound, preferably sodium sulfite.
