A weekly look at new products, innovations

Editor's Note: Each week, Rubber & Plastics News will take a look at some of the rubber industry's new products and innovations on www.rubbernews.com. Does your company have a new product or innovation? To be considered for inclusion in this recurring feature, email [email protected].

Ashby Cross Co. has released DXR Adhesive Dispensing System, a system that features a portable dispenser and a mobile bulk refilling station for assembly and manufacturing environments requiring multiple dispense points or dispensers.

Ashby Cross Co. said the dispensing system features a portable dispenser gun that provides mode control for dots, shots or bead output, a fixed shot volume adjustment and a precise mixing ratio with reproducible results. Combining the advantages of point of application metering with the use of bulk packaged materials, the system's mobile refill station serves multiple dispensers which recharge directly for safe and simple on-site refilling.

The dispensing system is priced according to configuration and is available with fixed volumetric dispensing ratios ranging from 1:1 to 10:1.

Ashby Cross Co. said the Ashby Cross DXR Adhesive Dispensing System has a patented mixer connection, which eliminates cross contamination. The refill station includes two five-gallon containers and the company said the system is ideally suited for use with epoxies, silicones, acrylics and MMA in a variety of applications.

Arkema Inc. has unveiled the next generation high rubber impact modifier to its Durastrength impact modifier product line, Durastrength 350, a high efficiency acrylic impact modifier designed to provide exceptional toughness to weatherable PVC applications.

Arkema said it designed Durastrength 350 to provide the impact resistance necessary for today's demanding building and construction formulations, while providing outstanding impact properties over a wide processing window for rigid vinyl products.

Durastrength 350 impact modifier's unique properties can be used for window profiles, siding and capstock, Arkema said, where long-term weather resistance is necessary, and impact and color retention are key. The low melt viscosity and rapid fusion characteristics provide optimum conditions for difficult injection molding applications, it said. Durastrength 350 impact modifier is supplied as white powder. It is available in 50-pound bags or 1,800-pound super sacks.

Dow Corning Corp. has introduced its Dow Corning dispensable thermal pads, an advanced technology developed for more cost-effective thermal management of high-performance electronics targeting LED lamp and luminaires, data servers, telecommunications equipment and transportation applications.

Dow Corning said the materials enable manufacturers to quickly and precisely print a layer of thermally conductive curable silicone compound in controllable thicknesses on complex-shaped substrates while ensuring excellent thermal management properties and reduced manufacturing cost.

The technology offers the potential to reduce material costs by 30 to 60 percent by eliminating the waste more common to conventional fabricated thermal pads, Dow Corning said, and it also enhances thermal performance and accelerates manufacturing cycles. The materials can be applied via standard screen or stencil print processes, or by using standard dispensing equipment.

Dow Corning's new line encompasses four products, distinguished by varying levels of thermal conductivity with or without controlled bond line thicknesses. Dow Corning TC-4015 and TC-4016 Dispensable Thermal Pads offer thermal conductivity of 1.5 W/mK, and Dow Corning TC-4025 and TC-4026 Dispensable Thermal Pads offer higher 2.5 W/mK thermal conductivity. Two grades, Dow Corning TC-4016 and TC-4026 Dispensable Thermal Pads, incorporate glass beads to offer improved control over bond line thickness.

Sick Inc. has released the Sam inductive sensor for speed and acceleration monitoring.

Previously, a rotational speed had to be adjusted using a basic speed monitor, the company said, but the Sam's acceleration monitoring functionality measures the change in speed, detecting a break almost immediately.

The Sam gives both a raw pulse output and a programmable, discrete switching output and has a monitoring range of up to 12,000 pulses per minute. To reduce false trips, the Sam offers three modes— no delay, fixed time delay and upper threshold delay.

The Sam is can be a solution for reducing scrap and downtime in wire, thread and web break applications.
