MonTech offers free e-guide to laboratory press design
MonTech Rubber Testing Solutions offers its free e-guide: The Official Lab Manager’s Guide to Lab Press Design. When designing a new rubber or silicone laboratory press, one needs to ask the right questions. This downloadable guide teaches readers how to build a laboratory press with their application, production and safety requirements in mind. The e-guide outlines key points to consider, including footprint design; specific application options; increasing production capacity; and user ergonomics and safety
Book of the Day: Engineered Rubber Products – Introduction to Design, Manufacture and Testing
The successful manufacture of engineered rubber products is complicated. It involves different disciplines, materials, and types and designs of equipment. Problems sometimes occur because of less-than-desirable communication among personnel involved in the development and manufacture of rubber products. This book’s intent is to improve communication among different disciplines. Using a systems approach, it is further intended to introduce chemists and engineers to the unique capabilities of rubber in a wide range of tire and non-tire products
RDAbbott to attend Rubber Division, ACS Spring Technical Meeting
R.D. Abbott Co., Inc. (RDAbbott) will reconnect with customers and colleagues at the Spring Technical Meeting for Rubber Division, ACS on Tuesday, April 27, and Wednesday, April 28. RDAbbott will attend technical meetings and share tabletop exhibits at this hybrid event, which will be held at the Embassy Suites by Hilton, Cleveland Rockside, in Independence, Ohio. Last year’s in-person spring meeting was cancelled because of the coronavirus.

Specialty Silicone Products explains EMI shielding for electric vehicles
In a new white paper, Specialty Silicone Products (SSP) explains what engineers need to know about protecting EVs from EMI. SSP, a global provider of conductive elastomers for EMI gaskets, examines the sources of EMI for all types of electric vehicles and explains how, when, where and why to use particle-filled silicones. Moreover, SSP describes cost-effective but high-performing alternatives to silver filled materials

Keltan 2470E EPDM Grade for Excellent Electrical Performance in Wire and Cable
Ethylene propylene diene polymers (EPDM) are the most widely used rubbers in the range of available synthetic rubbers for non-tire applications. Due to the unsaturated backbone, EPDM can be employed in various applications in which characteristics such as resistance to ozone, heat and moisture, flexibility at low temperatures, a wide range of tensile strength and hardness levels, and excellent electrical insulating properties are important
Extrusion
Dimensional Change Resulting From Swell And Drawdown Of Extruded Polymers
Understanding and predicting how extruded profile dimensions change along an extrusion line contribute significantly to the design of shaping dies and the effectiveness of dimensional control. Upon exiting the extrusion die, the dimensions of nonsymmetric profiles change non-uniformly along the line due to swell and drawdown.

Oil, Gas & Energy
Sealing solutions offered for air and sea
In aerospace, demand has increased for actuator designs that meet and exceed more rigorous performance standards, while providing unprecedented safety and reliability. Some of these requirements, such as the fire and flammability resistance defined in ISO 2685 and RTCA DO-160, go beyond the use of standard hydraulic seal designs. These high temperature, challenging requirements significantly impact commercial aircraft engine safety, and often force the use of heavy, bulky, easily damaged and costly external fire shielding. As a result, Greene Tweed developed the Fireproof Hydraulic Seal (FPH Seal), which has been specifically engineered to meet this need and establish a shielding alternative.
Testing & Instruments
Polymer quality control: Real-time near infrared testing cuts cost up to 90%
While traditional testing is critical in determining polymerization factors, from simple moisture content to complete chemical analysis, it is time consuming, labor intensive, and has substantial ongoing costs in terms of the purchase and disposal of consumables such as reagents and chemicals. Conventionally, it requires sample preparation, and can take five to 15 minutes for moisture testing, and 24 to 48 hours for more complex chemical testing. Fortunately, an approach using near infrared (NIR) spectroscopy can now provide immediate, real time laboratory quality readings via a non-contact, secondary measurement method that can deliver moisture, composition analysis and even full spectrum readings for a fraction of the running cost of conventional methods.

Almond Production Residues As Natural Rubber Fillers
Carbon black is commonly used as a filler in rubber and plastic compounds. It is composed of over 90% carbon, with low oxygen and hydrogen content, mainly forming surface functional groups which may participate in polymer reinforcement. Raw almond shells are composed of cellulose, hemicellulose and lignin, representing less than 50% carbon, over 40% oxygen, and at times significant amounts of moisture. The relatively polar nature of almond shells, and their tendency to degrade at processing temperatures, presents a less than ideal alternative when considering fillers for hydrocarbon polymers.
