KRX-RPA 700 Rubber Process Analyzer
Overview
Product Overview
The KOREXAN KRX-RPA 700 Rubber Process Analyzer is a high-performance rheological testing system engineered for comprehensive characterization of uncured, curing, and vulcanized rubber compounds. Designed for advanced research, product development, quality assurance, and manufacturing process optimization, the instrument delivers precise and highly repeatable evaluation of viscoelastic properties, curing behavior, and processing characteristics across the complete rubber curing cycle. Combining advanced oscillatory rheometry with precision engineering, the KRX-RPA 700 enables laboratories to make faster, more confident decisions while improving material performance and production consistency.
Utilizing advanced oscillatory rheometry technology, the system applies controlled oscillatory deformation to a specimen enclosed within a precision-engineered sealed biconical die. The resulting torque response is measured with exceptional accuracy over a wide frequency, strain, torque, and temperature range, allowing detailed characterization of viscoelastic behavior, curing kinetics, and material processability. Its direct-drive motor, high-resolution sensors, and precision temperature control ensure outstanding measurement stability, accuracy, and repeatability under demanding testing conditions.
The KRX-RPA 700 supports a comprehensive range of testing capabilities including isothermal curing analysis, non-isothermal testing, frequency sweep, strain sweep, Large-Amplitude Oscillatory Shear (LAOS), and stress relaxation measurements. These advanced rheological techniques provide valuable insight into compound development, batch consistency, process optimization, and final product performance, enabling manufacturers to optimize formulations and accelerate material innovation.
Engineered for maximum laboratory productivity, the instrument integrates a precision pneumatic pressure system, high-speed data acquisition electronics, intelligent instrument control, and licensed analysis software for complete instrument operation, real-time data acquisition, graphical analysis, reporting, and efficient test management. Its robust mechanical construction and advanced control architecture deliver exceptional operational reliability while maintaining long-term measurement integrity throughout continuous laboratory and industrial use.
Built to comply with internationally recognized ASTM, ISO, and DIN testing standards, the KRX-RPA 700 provides reliable, reproducible, and standards-based rheological evaluation for modern polymer laboratories. The system is ideally suited for natural rubber, synthetic rubber, thermoplastic elastomers, specialty elastomers, polymer compounds, adhesives, sealants, cables, automotive materials, and advanced industrial research applications requiring precise material characterization and quality control.
Ideal for polymer compound development, quality control, tire and tread compounding, elastomer research, specialty chemicals, material testing, industrial manufacturing, and academic research laboratories, the KOREXAN KRX-RPA 700 combines precision engineering, intelligent measurement technology, and exceptional reliability to deliver accurate rheological analysis, improved process efficiency, and accelerated innovation across the entire rubber product development lifecycle.
