TR Tester
TM-3525
Ueshima Japan
12 months
This device measures the retraction rate of elongation when a specimen is subjected to a certain elongation, frozen, and then gradually warmed up. The encoder is used to measure the retraction, and a PC is used to set test conditions, display data (TR value, retraction rate), draw graphs (temperature, retraction rate), and save the results to a file. Standard JIS K 6261-4,ISO2921,ASTM D 1329.

- Equipped with a dual-stage refrigeration system, ethanol can be cooled down to -73°C. The chiller can be operated on a timer, so testing can be started immediately after the time is set in advance.
- The data measured by the testing machine are linked to the PC, the test data can be automatically aggregated, and the results can be displayed.

AB-1150 LAMBOURN ABRASION TESTER
Among various abrasion tester for rubber such as tire, belt, and sole etc., it is Lambourn Type Abrasion Tester that is evaluated as the best reappearance in JIS K6264(Abrasion Testing Method of Vulcanized Rubber) as well as high correlation with the result of product test.
FPS WEAR TESTING SYSTEM
A Lambourn abrasion tester or conventional FPS tester, which is used for abrasion tests of high polymer material for such products like tire and belt, controls slip ratio or speed difference between test piece and road wheel while doing an abrasion test.
* FPS stands for Field Performance Simulation.

Mooney Viscometer
VR-1130 Series Mooney Viscometer: ●Measurement of Mooney viscosity for unvulcanized rubber ●Measurement of scorch time for unvulcanized rubber ●Measurement of Mooney stress relaxation for unvulcanized rubber (MODEL: VR-1132), ムーニー粘度計
Flat Die Rheometer (FDR)

GEHMAN’S TORSION TESTER
Standard: JIS K 6261, ISO 1432, ASTM D1053 , Rubber loses resiliency as temperature goes down. The frozen rubber can't keep its essential characteristics under the temperature below Glass Transition Point. In fact, the rubber applications under severe environments such as vehicle tire in frozen area and aircraft components in the stratosphere are seriously affected. It is a vital importance with the rubber applicants to test low temperature characteristics of vulcanized rubber.
Cable Abrasion Tester
The Cable Abrasion Tester is for cable insulation and is of the type that fixes a test piece in contact with abrasion tape,loads it,and moves the abrasion tape at a speed of 1,500 mm/min. The tester also measures the length of abrasion tape used until the cable insulation abrasions out and the conductor wire gets into contact with the wear tape. Applicable Standard:JIS C3406 Length of Test Piece:Approx 900mm
Durometer Shore A - Shore D
The Durometer comes in two models (type A for midium materials to be measured and type D for hard materials). Type D is suitable for the cases where type A measurement values reach 90 or more.
Low Temperature Brittleness Tester
Low Temperature Brittleness Tester The brittleness tester conforms to JIS K 6261 / JIS K 7216 and determines the brittleness temperature and the 50% brittleness temperature of vulcanized rubber and plastics in a low-temperature environment. TM-2131 is the single type which comes with a set of sample holder, holding five samples, and TM2136 is the multiple type with four sets of sample holders with which four sets of five samples can be tested continuously just by turning a dial to change sample
