Essentially Rubber – Innovation

Leading-edge designs and applications showing how elastomer materials contribute to all aspects of life and lifestyle in the 21st century:

French company Borflex has reported on a project for a museum that owns 74 fighter aircraft: renovating the leading edges of the Jaguar A 157. The refurbishment presented a series of challenges, not least because the leading edges must withstand extreme flight conditions, including temperature variations and aerodynamic forces. Technical precision of the materials used was also crucial to ensure the aircraft's performance and safety, while the project had to comply with the strict standards of the aviation industry.  Read more

Ansell claims its new HyFlex Ultra-Lightweight cut protection series offers new levels of protection, comfort, and dexterity throughout the workday. Employing a new cut-resistance technology and an advanced single HPPE yarn, the gloves are said to be 20% lighter while delivering up to 12 times greater cut resistance and maintaining comfort and flexibility. With EN ISO cut protection levels ranging from C to F+, workers can select the exact level of protection required for each task, ensuring both maximum safety and ease of movement. Breathability reduces the need for glove changes, while touchscreen compatibility enables workers to operate both tools and devices.

Kraiburg TPE has applied its thermoplastics elastomers technology to luggage handles: leveraging the “balance of performance, durability, and sustainability,” of the material. The RC/PCR/AP - Thermolast R series is said to offer enhanced adhesion to polypropylene as well as better grip and lighter weight than EPDM and PVC alternatives. The compound also exhibits “excellent tensile strength and resistance to wear, ensuring product lifespan.” The TPE has a non-sticky surface and has a temperature stability of up to 80°C, added Kraiburg TPE.

Trelleborg has spotlighted the use of its technology in dampening noise and vibration on towboats using up to 11,000hp to transport huge barges on the Mississippi river. The powerful vessels commonly tow over a dozen barges: transporting grain, corn, soybeans, iron, rubber, coal and other bulk commodities along the 2,350-mile US waterway. The rubber mounts and steel springs most Mississippi towboats use cannot isolate a crew’s sleeping quarters sufficiently to shield them from the noise and vibration of operating machinery.  (Read more)

US-based Rubber B has developed a new “blocked integrated” rubber strap for the recently launched Rolex Daytona 126500LN. The luxury watchstrap maker employed its 'VulChromatic' technology in the manufacturing process: forging two rubber 'masses' into a single, permanent piece. The process eliminates painted layers or bonding seams, ensuring that straps remain supple, flexible, and colourfast, said Rubber B. The straps are also claimed to deliver “exceptional" tensile strength and resilience as well as increased resistance to oxidation, abrasion and UV.

In Japan, Sumitomo Riko has developed a heat-dissipating, soundproofing material produced using 'magnetic induction foaming' (MIF) technology." The material is said to deliver 10 to 50 times better heat dissipation than a conventional urethane-based alternatives. Target applications include in-vehicle electrical equipment such as e-axles, battery junction boxes and power seat motor covers.

Kraiburg TPE has provided thermoplastic elastomers for the production of modern door stoppers, for both residential and commercial applications. The Thermolast K materials enhance part-durability by providing strong bonding with polypropylene components. Furthermore, the TPE retains shape and functionality under continuous compression, minimising the need for replacements. Other attributes include smooth touch, abrasion resistance, low surface friction, optimised demoulding and being colourable, said Kraiburg TPE.

Yokohama Rubber MB Japan has released a conveyor belt product with “excellent flame retardant oil resistance.” it announced 6 Dec. The Criterion Z series system, features a special shape that enables steep incline and vertical conveyance, which is not possible with ordinary conveyor belts. Transport efficiency is improved by combining sidewalls and cleats – a plate that passes horizontally to the belt to prevent slippage – to increase load capacity and prevent spillage.

Busto Arsizio, Italy-based Comerio Ercole is working to enhance the performance of its equipment across a series of metrics. The programme has included the recent completion of testing on a special calendering plant for rubber sheets based on a ‘miniduplex’ configuration. The four-roll set-up is capable of providing a rubber thickness of only 0.075 mm for each rubber sheet. Read more

Kraiburg TPE has unveiled new thermoplastic elastomer materials specifically designed for car pedal manufacturing. The Thermolast K product are tailored to offer: enhanced adhesion to PP; soft-touch properties: “excellent” resistance to wear & tear and colourability. The TPEs are also said to offer benefits in terms of “controlled” emission and odour, recyclability and processing.

French rubber injection moulding machine maker REP has developed a press for a “highly demanding” customer project. With a clamping force of 8,000kN and a working area over 1m x 1.5m long, the S08 is optimised for large flat gasket applications, demanding especially high levels of quality and precision. The design employs multiple synchronised clamping units as well as large-sized heating plates and adjustable configurations. Injection of long thin sections is facilitated by an injection pressure of up to 3,000 bar and circuit division with several injection units.

Mitsubishi Chemical’s plant-derived polyol BioPTMG has been adopted by Kahei Co. Ltd as a synthetic leather material. Items such as shoulder bags and tissue cases made with this bio-synthetic leather will be sold on the market via Triple A Co. Ltd, a planner and marketer of sustainable products.  Read more

Freudenberg Sealing Technologies has introduced new polymer-based technologies for automotive batteries: launching three new products earlier this month. Unveiled at the 2024 Battery Show, 7-10 Oct in Detroit, the German-based sealing products manufacturer's developments include: advanced thermal barriers; prismatic battery cell caps; and prismatic envelopes for batteries.  Read more

A sneaker made with airbag fabric remnants in a joint project by Toyoda Gosei and Asics Corp., has won a Good Design Award 2024 by the Japan Institute of Design Promotion. The prize-winning Gel-Sonoma 15-50 shoes, which were launched back in early 2023, feature uppers made from airbag fabric that would otherwise be discarded, TG said a 16 Oct announcement.   Read more
