Elmet’s new all-electric cold runner maximizes LSR injection molding
ELMET’s new all-electric SMARTshot E valve gate cold runner system has servo-driven nozzle needles to maximize flexibility, precision and controllability when injecting two-component liquid silicone rubbers (LSR) into multi-cavity molds. It complements ELMET’s range of SMARTshot Liquid Injection Molding (LIM) cold runners which also includes a pneumatic version, the model P, and a hybrid version with pneumatic needle movement and electrical stroke adjustment, the model PE
Global silicone and silane market forecast at $27 billion by 2030
The Global Silicone and Silane Market size is estimated to be USD 15.98 billion in 2019 and is predicted to reach USD 27.62 billion by 2030 with a CAGR of 5.1% from 2020-2030. Silicone is a polymer consist of hydrogen, carbon and other chemicals and used as resin, grease, oil and other in various industries such as automobile, construction, medical, electronics and others. Silane is an organic compound consists of multiple or single silicon carbon bond and it is produced by reaction of silica sand with magnesium in the presence of hydrochloric acid. Silane helps in the binding of two compounds together in different industries.
PEFC focuses on sustainable rubber in ASEAN countries
As 85% of the world’s natural rubber comes from Southeast Asia, the Programme for the Endorsement of Forest Certification (PEFC) has focused its attention this year on the region to help make sure it is harvested and supplied using best sustainable practices

Novel value-added thermoplastic elastomers bonding to polyamides
Bonding thermoplastic elastomers to polar and non-polar substrates has been widely studied in the past few decades to create products that enhance ergonomic comfort and functionality. Overmolding a TPE compared to two-shot molding is a litmus test for bonding the material to the substrate. The TPE must wet the cold surface and must melt a few nanometers of the surface of the substrate that is being overmolded on to facilitate bonding.

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
Guill Tool introduces a co-extrusion crosshead designed for irrigation tubing
Guill Tool introduces Series 824, a co-extrusion crosshead designed for irrigation tubing with an emitter tool. Manufactured from stainless steel, this new crosshead features balanced flow design with spiral technology that improves flow characteristics at all extruder speeds. Dual feed ports provide concentric compound flow, while the splits flow from one extruder to feed the inside and outside layers via a manifold assembly. Series 824 is adaptable to all popular extruders on the market currently

EMI silicone now part of U.S. Department of Defense qualified products list
Specialty Silicone Products (SSP) announced that SSP-2569-65, an EMI silicone filled with silver-copper particles, is now part of the Qualified Product List (QPL) for MIL-DTL-83528, Type A. In a July 22 letter, the Defense Logistics Agency (DLA) informed SSP that SSP-2569-65, a 65 durometer conductive elastomer for shielding and sealing, passed qualification testing and has been added to QPL MIL-DTL-83528 for specific drawings and material types.

Thermoplastic polymer has API 610 recognition
CDI Energy Products announced that its latest material to achieve API 610 recognition outperformed service life expectations under extremely corrosive sulfuric acid conditions. API 610 is the standard for centrifugal pumps for the petroleum, petrochemical and natural gas industries. CDI’s proprietary thermoplastic polymer composite, Dures 200, was the foundation for critical components developed for an API 610 vertical single casing diffuser pump (VS1) for a high production sulfuric acid plant. CDI’s material scientists and engineers collaborated with the pump OEM to custom design suction bell eye case rings, bowl eye case rings and bowl bushings which could sustain differential pressures of over 200 psi, coupled with an extreme temperature profile of -20°F to 105°F (-28.8°C to 40.55°C).
Testing & Instruments
Endurica tames road loads with new software release
Endurica LLC announces a new feature in its Endurica CL fatigue solver: automatic block cycle generation. The feature enables users to extract a simplified durability testing schedule (known as a block cycle test) from multi-channel road loads recorded at the testing track. The simplified testing schedule preserves the most essential features of the original road load history, while maintaining the original failure mode and discarding non-critical load history. The capability enables rubber part suppliers to design fatigue tests that execute quickly and that develop realistic damage. It enables car makers to ensure durability under actual driving conditions.

Latex and Natural Rubber
Staying relevant in a changing industry
In previous Rubber World columns, I have discussed the reintroduction of the manufacture of latex gloves back into the U.S. after a 25 year absence. During those years, in Southeast Asia, there have been significant, evolutionary improvements to the equipment, processing, formulations, and the latex itself. The challenge we face is to develop a competitive, sustainable manufacturing capability in the U.S., utilizing some of the personnel who were involved in glove manufacturing years ago, and merging their experience with new ways of thinking and problem solving.
