Cray Valley has introduced Krasol LBH 5000M, the newest addition to its portfolio of liquid polybutadiene additives. The mono-hydroxyl functional oligomer (monol) is a versatile additive that supports new applications for reactive polybutadienes, Cray Valley said, and also can be hydrogenated to produce a clear liquid (Krasol HLBH 5000M).
The Exton, Pa.-based wholly owned subsidiary of Total S.A. said that a long-chain alcohol (C250), the monol retains resistance to acids and bases in harsh environments, is hydrolytically stable and is compatible with hydrocarbons. In composite systems the oligomeric chain can promote surface modification and adhesion, as well as hydrophobicity or rheological modification. Krasol is compatible with many substrates, including polyolefins. The monols can be further modified for use as macromonomers, surfactants, compatibilizers, fluid additives and other value applications.

Sick Inc. launched the DFS2X line of programmable incremental 16-bit encoders, which features a compact, rugged mechanical design and a metal code disc that fits in nearly all applications.
Sick said the DFS2X encoders offer shaft, blind-hollow and through-hollow versions in a small 2-inch housing, as well as a shaft version with a 2½-inch housing. In addition to its small size, the IP 65-rated metal design is resistant to shock and vibrations, Sick said, which reduces downtime and enables use in harsh environments. A variety of programmable options give users the ability to configure the resolution, the zero pulse phase and other settings on a single encoder, helping to reduce spare parts inventory.

Applied Silicone Corp. has unveiled its Ultra-Soft LSR-brand liquid silicone rubber products for the implantable materials market. The materials are formulated specifically for long-term implantation of more than 30 days, and the firm said the materials provide a soft LSR measured in Type OO and Type OOO durometer scales.
Applied Silicone Corp. said soft silicone elastomers historically have been ideal candidates for soft tissue simulation, cushioning and dampening, but were limited to non-reinforced gel systems that are prone to fracture and require a thin elastomer membrane to enhance integrity. Applied Silicone's Type OO and Type OOO Soft LSRs possess both a soft feel and greater mechanical strength with minimal surface tackiness, according to the firm. They also have low to medium viscosities suitable for knife-coating films, injection molding soft parts with complex geometries, or solvent-less dip-casting of thin membranes.
Soft LSRs are fully biocompatible as tested under the ISO 10993 standard for permanent contact with the body or long-term implantation.
