Digital Tensile Testing Machine

Test Method – IS 3400:2012 Part I

Feature –

  • Variable frequency 2 -speed control
  • Digital load indication
  • Capacity – 5000 N

Application – For determining the tensile and elongation properties for rubber compounds

Ozone Chamber

Test Method – IS 9573:2012

Ozone Chamber covers the estimation of the resistance of vulcanized rubber to cracking when exposed to an atmosphere containing ozone. The rubber specimens are kept under a surface tensile strain, and the ozone content or partial pressure in the test chamber is maintained at a fixed value. It provides precise and accurate ozone (O3) concentration environment for rubber and polymer testing

Application – It is used to evaluate the ozone ageing resisting performance of Rubber.

Fourier Transformation Infrared Spectrometer

Test method – ISO 4650:2012 (E)

Feature –

  • Real time, ratio-recording instrument with built in handling facilities
  • Continuous recording of infrared transmittance or absorbance of sample as a function of frequency to record spectra.
  • Minimum sample preparation required for testing.

Application – Qualitative identification and estimation of Compounds in polymer materials

Humidity Chamber

Test Method – IS 3400:2012 Part I

Feature –

  • Temperature upto 10 Deg C / 60 Deg C and humidity range 40% to 95% Rh
  • Microprocessor controller with LCD display and sensor for precise control of temperature and humidity.
  • Self-Diagnosis for errors
  • PC Compatible

Application – For conditioning of Rubber samples prior to testing

Super Suraksha Hose 

  • There are various sizes available in Super Suraksha i.e., ½ inch and ¾ inch which can be used for 47.5 kg Cylinder and 425 kg cylinder.
  • This Hose is tested as per IS 9573 : 2017 Part 1

LERC Tight Joint

New Design LERC Tight Joint exhibits far more superior properties than the existing Nitrile Rubber Tight Joint

  • Can withstand a pressure of 15 bar vis-à-vis the existing 2 bar.
  • Assured Customer Safety, even if the o-ring is leaking.
  • Increased DPR life
Pantone Spectrometer

  • A spectrophotometer that compares Pantone shades with RPVC film samples, providing L, A, B, ΔL, ΔA, ΔB, and ΔE values.

    The spectrophotometer is an indispensable tool for quantifying and comparing colors objectively.

PADC Safety Caps 

  • This is a POLYPROPYLENE caps.
  • The safety caps are fixed onto the valves and are of lesser weight compared to Delrin.
  • This is stronger than the Delrin Caps as we have also tested this in our ball drop testing bench .
  • The pressure test of 17 kg/cm2 and the leak is checked by observing for any bubbles between the SC Valves and the safety caps.

Thermogravimetric analysis (TGA)

Thermogravimetric analysis (TGA) is a method of thermal analysis in which changes in physical and chemical properties of materials are measured as a function of increasing temperature (with constant heating rate) or as a function of time (with constant temperature and/or constant mass loss).

Ageing Oven 

The rubber is exposed to controlled deteriorating factors for a specific period of time.

Hardness Test by Automatic IRHD Hardness Tester 

  • This facility facilitates testing of Hardness of Rubber slabs, Rubber buttons & O-Rings .
  • The Rubber slabs / buttons are kept on the centering table of the Hardness Tester.
  • For O-Rings, a centering device on the table helps in holding the O-Ring samples.
  • In both the cases, hardness measurement is done automatically by start of the button.
  • The hardness requirement is 60± 3 IRHD for NBR O-Rings.

 

Video Measuring System

A CNC Multi-Sensor Video Measuring Machine (3D machine) with Vision (Optics), Point Laser and Tactile Probing for accurate automatic measurement of the rubber and plastic components.

Differential Scanning Calorimeter

Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature.[1] Both the sample and reference are maintained at nearly the same temperature throughout the experiment.

Specific Gravity

The specific gravity of an object is the density of that object divided by the density of water.
