Malvern, UK: Holly Asphalt's purchase of five Dynamic Shear Rheometers over a period of eight years is testament to Malvern's ability to provide exemplary support to asphalt producers, and to sustain and nourish long-term commercial relationships. Holly Asphalt operates five terminals in the southwestern US and is part of the Holly Corporation (www.hollycorp.com), an independent petroleum refiner and marketer. Like all asphalt producers, Holly uses rheometry for final QC. Rheological properties have a critical impact on asphalt pavement performance and testing to well-defined industry standards is essential before shipping.
"For me what really differentiates Malvern is exceptional customer support," comments Bob McGennis, Technical Manager, Holly Corporation. "The company has a non-bureaucratic, 'can-do' attitude and will go that extra mile to provide us with everything we need. Bohlin was the first company to develop a rheometer specifically designed to meet the needs of asphalt producers. Malvern has capitalised and built on this legacy. They really understand the asphalt industry and our reliance on sound and accurate rheological data."
Asphalt testing is a demanding rheological application, primarily because of the temperature sensitivity of measurements. The Superpave(TM) specifications set out criteria for QA/QC acceptance for different grades, and test methods are very closely defined. Malvern offers a suite of rheometers specified to meet the demands of the industry, with integral, user-friendly software that automates and streamlines asphalt measurement. These solutions are supported by information rich, industry-specific web content, an ambitious and informative on-line education programme and a global network of application specialists. www.malvern.com/asphalt
About Malvern Instruments
Malvern Instruments provides a range of complementary materials characterization tools that deliver inter-related measurements reflecting the complexities of particulates and disperse systems, nanomaterials and macromolecules. Analytical instruments from Malvern are used in the characterization of a wide variety of materials, from industrial bulk powders to nanomaterials and delicate macromolecules. A broad portfolio of innovative technologies is combined with intelligent, user-friendly software. These systems deliver industrially relevant data enabling our customers to make the connection between micro (such as particle size) and macro (bulk) material properties (rheology) and chemical composition (chemical imaging).
Particle size, particle shape, zeta potential, molecular weight, chemical composition and rheological properties measurements are now joined by advanced chromatography solutions (GPC/SEC), extending Malvern's technologies for protein molecular weight, size and aggregation measurements, and synthetic polymer molecular weight and distribution. The company's laboratory, at-line, on-line and in-line solutions are proven in sectors as diverse as cement production and pharmaceutical drug discovery.
Headquartered in Malvern, UK, Malvern Instruments has subsidiary organizations in all major European markets, North America, China, Korea and Japan, a joint venture in India, a global distributor network and applications laboratories around the world. www.malvern.com
