Foam Pressure Rheometer

The Foam Pressure Rheometer is specially designed for foam testing as per testing standards. It provides accuracy of automatic die oscillating frequency and torque transmission. The associated software provides contour lines of physical properties to help the users choose excellent formula matching.

Standard Functions of the Foam Pressure Rheometer

Optional Functions 

Optimum Cure  Analysis System (OCAS)

  • Including this system’s tools, particular software, temperature measurement, temperature calibration of tools etc.
  • Combine the curing data from rheometer to the processing time from workshop.
  • Provide direct values in percentage (%) to understand the curing process from different positions on the same specimen.
  • Calculate the best curing time at workshop to avoid the under-curing or over-curing at particular position.

SPC Software

(Statistical Process Control software) is able to analyze and store the following test data:

  • Data storage: ML, MH, scorch time, cure time, elastic and viscous values, cure rate, and test date
  • Provide statistical analysis of curing by X-Rm, X-R, Normal Distribution, and Histogram Chart.
  • Evaluation of cure testing properties and making classificationn in A, B or defect categories.

VCH  software

Able to analyse functions of compounding homogeneity:

  • Showing the compound viscous and elastic variation in the curing process by dynamic diagram.
  • Showing whether moving die frequency and torque transmitting normal.
  • Support detecting mechanical noise.

UCAD software

  • Able to choose the excellent formula-matching and experimental recommendations:
  • When the formula is renewed by single or multiple chemicals, this software will analyse the interaction between the new chemicals and the requested product properties.
  • Furthermore, it will provide new formulas by reorganizing chemical quantity matching and give experimental recommendations.
  • The math model of this software can arrange testing points in the experimental disposition space into rationalizations, minimizing the testing frequencies, but still can sufficiently obtain an effective data.
  • Varieties of functions in this software can obtain the best combinations among the demand of product property, cost, and the feasibility of producing technology.

Features of Foam Pressure Rheometer

  • Two types of mold cavity: Chamber with seal and Chamber without seal.
  • Both types can apply to the listed additional software
  • New type rheometer offers good repeatability and reproducibility based on the anti-noise circuit and the exclusive DSP analysis program improves significantly the machine design and quality.
  • Able to calibrate torque and loss angle automatically.
  • Noise from the equipment and torque transmission can be checked automatically by our VCH software.
  • It would not exceed 2 min  and  40 seconds when heating up from room temperature to the equilibrium of 170°C±0.3°C
  • Time needed for changing temperature:
  • From 170°C to 190°C and reach the  state of equilibrium 190°C±0.3°C....within 55 secs.
  • From 190°C to 170°C and reach the  state of equilibrium 170°C±0.3°C....within 1min 40secs.
  • During testing, die chamber temperature will be redeemed to the tolerance of ±0.3°C within 30±3 seconds from die closure.
  • The software can check whether motor speed (or die oscillation frequency) conforming to the 100rpm (or 100cpm) regulated in standards. (ASTM/ISO)
  • With built-in software able to provide suitable volume of specimen to fit the die cavity.
