New carbon black alternative is made from scrap tires
Carbolytic Materials Company (CMC) of Maryville, MO, has developed a carbon black alternative with the trade name ApexCM that provides significant cost-reduction opportunities for many manufacturers who use carbon black to reinforce rubber products and tint plastic materials. Reclaimed from scrap tires, ApexCM is an affordable and environmentally sound option, according to its maker. Up to 40% of scrap tires generated annually could be successfully processed, saving critical landfill space.
"Our ability to provide a cost-effective alternative to carbon black for both tinting and reinforcing makes our product very appealing to manufacturers," says Ray Riek, CEO of CMC. "Although ApexCM does not substitute for carbon black in every application, the independent laboratory results have impressed many engineers with the versatility, functionality, and the overall value proposition."
ApexCM is a lower cost alternative to carbon black extracted from scrap tires. Carbolytic Materials Company uses cost-effective, proprietary technology to manufacture this revolutionary powder or pellet carbon. ApexCM can directly replace N700 and N900 carbon blacks for reinforcing and tinting rubber and plastics. It can also replace N500 and N600 carbon blacks in certain applications. With rising petroleum prices and enhanced focus on environmental savings, the value of reclaimed carbon black goes beyond the bottom line.
Recently the company has secured funding to build a new manufacturing facility in Maryville that is expected to produce between five and ten thousand tons of material annually.

A totally new technology for fastening sheet metal panels
The 1-035SL Captive-Joiner 9.5 SNAP-LINE offers all the benefits of traditional captive screws plus improved ease-of-use by the end-user, significant reduction in time of installation, and reduction in the risk of damage to sensitive electronic equipment housed inside enclosures. The Captive-Joiner also functions as a slam-to-close latch, requiring just a simple push of the panel against the frame to ensure latching.
The Captive-Joiner incorporates D•SNAP Technology making it quick and easy to install into the panel — reducing installation time up to 90% and giving significant cost savings. SNAP-LINE Captive-Joiners do not require mounting hardware (screw, nuts, or bolts) or tools for installation and can be used in blind applications when access to the back of the panel is restricted. They are ideal for applications under extreme vibration conditions because they will not loosen from the panel.

Gore improves thermal performance of its Direct Air Cooling Filter
The new GORE Cooling Filters improve thermal cooling while reducing both capital and operating costs in wireless base stations, MCPAs, base band units, power cabinets, switching systems, and other outdoor electronic enclosures.
The benefits of using the new GORE Cooling Filter are twofold: improved cooling efficiency and reduced costs. The filter improves thermal cooling approximately 20% by allowing higher airflow through the filter. At the same time, the membrane protects the electronic components by preventing fine contaminants such as dirt, dust, and sand from entering the enclosure. By increasing airflow while reducing potential contaminant damage, the GORE Cooling Filter improves overall reliability of telecommunications infrastructure.

Water-soluble oil specifically designed for aluminum
Rustlick Ultracut AL is a high-performance water-soluble oil specifically formulated for aluminum to prevent staining during the machining process. It can be used with all metals, including ferrous, non-ferrous, brass, bronze, and copper, though it is not recommended for use on magnesium.
The biostability of Rustlick Ultracut AL makes it highly resistant to bacteria and fungus, and with proper maintenance it can significantly prolong sump life. Rustlick Ultracut AL contains non-chlorinated EP additives as well as boundary lubricants and creates a light oil barrier that protects the working part and the machine from rust. Rustlick Ultracut AL is also great for environments with hard water problems since it provides strong emulsion stability. Rustlick Ultracut AL is available in 5- or 55-gal containers. It is a light brown viscous fluid in its concentrated form. It can be diluted 10:1 to 40:1 depending on the application.

Automatic press benefits from turret tool system
The PEMSERTER Series 2000 automatic press accommodates a dual-bowl option and QX Turret Tool system to allow quick and efficient changes between anvil tools while installing different types of self-clinching fasteners. Using the second bowl and the turret tool system, two fastener types can be installed in automatic feed mode and two in manual feed mode for steamlined job productivity and quality.
Touch-screen setup for all four stations includes selection of installation force and number of fasteners to be installed per workpiece. Operators are notified by visual and/or audible signal to rotate the turret to the next location or that the job is completed per setup. The CE-certified press offers a 24-in./61-cm throat depth, performs at cycle rates up to 2,750 strokes/hr, and delivers a ram force of 400 lb to 16,000 lb/2.7 kN to 71.2 kN.

Tough tight-bend hose for material handling apps
Parker Hannifin has released its 692 hose line, designed specifically for material handling and over-the-sheave applications. The design and construction of the 692 hose allows for a tighter bend radius compared to other hoses on the market, which saves space in the mast and increases visibility for the operator.
To improve visibility for the lift truck operator, components must be moved or reduced in size. Parker's new 692 hose addresses both concerns. Rated to the tightest bend radius in the industry, the 692 hose enables smaller pulleys to be used in the mast area, freeing up space. With a smaller outside diameter than other hoses, more area is gained in the mast area which improves visibility.

5. Shaft sealing solution optimizes lubricant retention
SKF low-friction Waveseal shaft-sealing solutions feature a specially molded lip to form a sinusoidal or wave pattern around the shaft surface. This unique pattern enables lubricant to be pumped back to the bearing for optimized lubricant retention while pushing dirt away from the lip/shaft surface (regardless of which way the shaft is turning) to protect against contamination.
The specially designed lip additionally generates 25% to 35% less heat at the contact point (minimizing premature seal failure due to heat checking, blistering, hardening, or lubricant breakdown); generates 20% less friction torque or drag; curbs shaft wear; and provides greater lip lubrication compared with standard lip versions.

6. Gel pad vibration isolators for damping performance
A new series of silicone gel pad vibration isolators from Advanced Antivibration Components features superior damping performance. V10Z61MSN Series isolators are designed for light to medium loads from 0.5 kgf to 2 kgf (1.1 lb to 4.4 lb) up to 15 kgf to 50 kgf (33.1 lb/leg to 110.2 lb/leg) per mount.
Their highest damping effect arises when the gel is compressed 10% to 30%. An important feature of these metric mounts is their ability to operate effectively over a very wide temperature range from -40°F to 392°F. They offer excellent chemical resistance and are low in compression set. Performance remains the same even after repeated use. They stay stable with low resonance magnification and have minimal horizontal deflection.

8. Get a handle on high-volume epoxy sealing
Multi-Seals offers an innovative alternative to liquid epoxy for high-volume, high-quality epoxy sealing applications. Uni-form epoxy preforms are one-part epoxy resins that are solid at room temperature. When heated, Uni-forms melt and cure, forming a consistent seal that protects components from dust, moisture, oil, flux, solvents, conformal coatings, and other contaminants.
Close tolerances on preform configurations, consistent pre-mixed ratios of resin to catalyst, and consistent viscosity from beginning to end of batch ensure uniform, high-quality results. Preforms can be dispensed as rapidly as 200 to 600 parts per minute with little or no operator training, and extensive operator experience is not required to produce uniform results. Preforms also eliminate pot-life concerns and costly cleanup procedures. Uni-forms are available in a wide range of shapes, sizes, and materials to accommodate diverse applications.
