Rubber, vulcanized — Determination of temperature rise and resistance to fatigue in flexometer testing: Constant-stress/strain flexometer. This machine determines change in complex modulus of elasticity E', E", tan6 and heating rate of rubber during the thermal fatigue process. Standard: ISO 4666, JIS K 6265,...

Ueshima Dynamic Mechanical Analyzer (DMA)

Ueshima MS-5150 Maron Type Mechanical Stability Tester : The Maron-type mechanical stability tester is a testing machine that measures the coagulation content in latex generated by rotating a rotating disc at a constant speed while pressing it against the sample container with a fixed pressure.

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.

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.

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.

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. Our Gehman's torsion tester TM-2535 is the most popular testing machine for this purpose and is adopted by JIS K6261(Equivalent to ISO 1432, ASTM D1053).

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

Ueshima VR-1130 Mooney Vicometer

Ueshima VR-3110 Rotorless Rheometer (Flat die rheometer - FDR) Applied Standards JIS K6300-2, ISO 6502, ASTM D 5289. Application: -Measurement of vulcanization characteristics of compounded rubber along with the vulcanization process. - Measurement of viscosity of raw and compounded rubber.

FR-7225 RTM Friction Tester enables to evaluate friction characteristics of tire tread compound on material testing basis, and can be tested in Dry, Wet, Ice conditions on ring shaped road surface. Test is performed by pressing specimen on constantly rotating ring shaped wheel at free rolling condition, or with slip ratio applied in 0 to +/- 95% range and measuring the friction force. Also, max. 30deg. slip angle can be applied on the specimen against it’s tangential line.

AB-1511 Akron abrasion tester

This equipment is used for evaluating wear resistance of
vulcanized or thermoplastic rubber conforming to the
German Industrial Standard (DIN 53516), and is also
incorporated into ISO4649, JIS K 6264-2, GB/T9867.

Ueshima GEER’S AGING OVEN Most important functions like temperature uniformity, wind velocity and air ventilation rate are in accordance with JIS K 6257 and/or JIS K 7212. ○The minimized shape of the series allows use on a table. We also provide with an exclusive stand. ○It is able to place two units in tiers, minimizing the footprint.

AB-1511 Akron Abrasion Tester is a widely used abrasion tester. It rotates a disc shaped test piece at a constant speed, to which an abrasion wheel is pressed with a fixed load. The abrasion wheel is set at an angle to the test piece, and abrasion amount will be observed. The model AB-1511 has a preset counter which will stop testing automatically when a set rotation is reached.

UESHIMA FT-1521 DEMATTIA FLEX CRACKING TESTER

The Constant Stress/Strain Flexometer measures the heating characteristics of a vulcanized rubber test piece when applied test amplitude the load(stress)controlling to a specified level applying to static load.It also performs tests by controlling a specified deflection(strain).Unlike conventional flexometers,this equipment adopts a special temperature detector to measure the inner temperature of a test piece during testing,thus making it possible to measure the real heat-up temperature.The test
