Ever since its startup in 1983, Tung Yu Hydraulic Machinery Co. Ltd. has remained true to its management philosophy, the “Down-to-earth sustainable management ” held by Chairman Yang Chen-Pin. The company has established a market presence with “Honest management ” with the result that “Tung Yu” brand products are distributed in more than 65 nations around the world under its brand name. Our products are widely acknowledged by industry and recognized by customers for their high brand exposure in the global rubber industry. Tung Yu specializes in the manufacture and distribution of rubber and silicon compression, injection molding machines, conveyor belt compression, tire specialty and retreading compression, solid tire machines, and hydraulic machines
Operations in the tire pyrolysis sector, as part of the tire recycling industry, are maturing to become not recycling operations, but serious producers of high grade raw materials in the rubber supply chain, on equal footing with virgin materials.
In a four-person household, the washing machine is in operation about one and a half hours a day. On average, it washes, rinses and spins about 250 times a year, cleaning some 1,000 kilograms of dirty laundry, an amount that is increasing all the time. Its components, particularly the rubber hose systems and rubber gaskets, are subjected to greater chemical and mechanical stresses than just about any other household appliance. Moisture, detergents and cleaning agents, particularly alkaline agents, as well as high water temperatures must not have an adverse effect on the material. Due to the long service life of the washing machine, all polymer parts, especially rubber parts, need to have a service life of at least 10 years, which means excellent resistance to aging.
Chemicals and Materials
Several products that can serve more than one purpose in rubber compounds are examined, including anti-reversion agents, dithiophosphates, curing activators and blowing agents.
The demand for performance and consistency of elastomer based compounds is growing quickly in all fields (tire, technical rubber goods, cables). Specifications regarding physical, mechanical and chemical properties, as well as “visual aspects” properties of the finished products are becoming more and more strict.
During compound production, all operations are involved, from the weighing to the storage of the semi-finished mixed compounds. The mixing operation plays a very important role, since it is the step where all ingredients are incorporated, dispersed and distributed.
Silicone & Medical
Elkem Silicones celebrated the grand opening of its new specialized facility for producing high purity medical silicones on Wednesday, September 28, in York, S.C. Customers and local, state, and federal officials, attended the event which included a ribbon-cutting ceremony, facility tours and a reception.
Designed to produce high purity silicone materials that meet the MedTech and Pharma market requirements, this new 18,000 sq.ft. site features state-of-the-art ISO-certified Class 7 and Class 8 clean rooms

Testing & Instruments
Properties of elastomers can be measured and computed by the DMYO-V oscillograph.
Alpine Advanced Materials has introduced Rapid Prototype Molding (RPM) using Addifab’s proprietary resin system and Nexa3D’s printers to give clients a more rapid tool manufacturing solution that provides a functional and testable part at a fraction of the cost. Complementing Alpine’s suite of high-performance engineered materials and advanced design services, RPM Freeform Injection Molding delivers complex injection molded parts more quickly and affordably than when using standard steel molds.
Thermoplastic Elastomers & Urethanes
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.
Latex and Natural Rubber
Continental pursues a holistic approach to make the complex and fragmented supply chains for natural rubber more sustainable: The latest digital technologies, local involvement in the cultivation of rubber, and close cooperation with strong partners are aimed at creating more transparency along the entire value chain. “We actively take responsibility in our supply chains. Only when natural rubber is responsibly sourced, we consider it a sustainable material,” says Claus Petschick, Head of Sustainability at Continental Tires. As of today, completely seamless traceability of natural rubber is technically impossible due to the high complexity of the supply chain. With its commitment, Continental is working at full speed on a blueprint for the sustainable and responsible structuring of supply chains.
