Until the middle of the 19th century, the rubber market was limited by the physical properties of natural rubber. After Charles Goodyear’s invention of vulcanisation in 1839, which modified natural rubber to withstand extreme temperature variation, the market for rubber goods widened significantly. Soon, the production of hoses, industrial bands, sheets, shoes and shoe soles […]
[vc_row][vc_column][vc_column_text]The stress relaxation of rubber can be tested using a Mooney Viscometer instrument. The rate of relaxation can be used to deduce important properties of rubber, including elastic and viscous behaviour, and rubber structure characteristics. Test Description A Mooney Viscometer consists of a rotor (cylindrical metal disc) embedded in a rubber sample inside a sealed […]
[vc_row][vc_column][vc_column_text]Despite having been introduced to the Europeans from the 15th century, the practical and industrial applications of natural rubber were not forthcoming for some time.

In January 2019 Prescott Instruments attended the India Rubber Expo (IRE) 2019, the 10th international exhibition and conference of its kind, held in Mumbai, India.
Over the course of 3 days, this much anticipated event served as a valuable platform to showcase a range of Prescott Instruments products and demonstrate our capabilities. Our testing experts were kept busy speaking with both new and existing customers across the rubber industry.
This year, we exhibited machines from both our Rheometer and Dynamic Testing lines. Our new all-electric 10kN DMA complete with temperature cabinet delivered clean, powerful testing of compounds and complete products up to 300Hz. The Multifunction Rheometer (MFR) and Mooney-Line Viscometer demonstrated our proven expertise at rheology across the rubber testing industry. Visitors were also welcome to test drive our Labline software, a sophisticated solution to the testing and data-processing needs of modern industry.
