RUBBER ANALYSIS& TESTING

WE KNOW POLYMERS - WE KNOW TESTING

Rubber and elastomers are widely used in mining, heavy industry, water,plumbing, construction and automotive industries. Products such as rubberconveyor belts, seals, gasket, vibration mounts/pads, etc.

ExcelPlas has combined the science of laboratory analysis and technicalproblem solving for application to a broad range of materials - especiallyrubber products. Our services extend beyond the standard chemical andphysical rubber testing required to meet industry and governmentspecifications.

Our rubber testing protocols apply to not only governmentcompliance and industry standards but also provide technical assistancein the areas of compound formulation, development of new materialsand processes, performance evaluations, and failure analysis.

Typical Examples of Rubber Products Testing:

• Seals and gaskets• O-rings• Hoses and tubing• Conveyor belts• Rubber linings• Industrial rubber components• Flexible couplings• Pipe and Valve linings• Expansion bellows• Vibration pads and blocks

Physical-Mechanical Testing

Our physical testing laboratory conducts mechanical testing for a widerange of industries, including automotive, industrial, consumer, medical and more. Our mechanical testing programs are developed to help ourclients meet ASTM, SAE, ISO, military, and federal specifications. Our rubberand plastics testing laboratory offers tensile, compression, adhesion,abrasion, flexing, aging and performance tests.

Chemical-Analytical Testing

The chemical testing laboratory has thecapability to perform rubber and polymertesting. We perform these tests using a widerange of analytical methods and wet chemistrytechniques, including compound formulations.This enables us to accurately identify andquantify constituent materials.

ExcelPlas offers the following rubber testing:

• Rubber Identification by Pyrolysis-Infra-Red Analysis (ASTM D3677)

• Rubber Identification by Thermogravimetric Analysis (ASTM D6370)

• Shore A Durometer Hardness of Rubbers (ASTM D2240)

• Taber Abrasion of Rubbers (ASTM D4060)

• Evaluating Chemical Resistance of Rubber (ASTM D543)

• Tensile Strength of Rubbers (ASTM D412)

• Heat Resistance of Rubbers (ASTM D573) 70 hr

• Oil Resistance of Rubbers (ASTM D471) – IRM 903 reference oil, 70 hrs

• Compression Set of Rubbers (ASTM D395)

• Ageing and environmental tests of rubber (AS 1683.26)

• Compression set under constant deflection at low & elevated temperatures (AS 1683.13 & ISO 815)

• Hardness Durometer A tests (AS 1683.15.2)

• Swelling of Rubbers in Liquids by the methods (AS 1683.23)

• Density and Specific Gravity of Rubbers (AS 1683 Part 4)

• Determination of rubber to metal bond strength (AS 1683.14.1)

• Tensile and Elongation Strength (AS1683.11)

• Tear tests (AS 1683.12 - Method C))

• Shear Modulus (ISO 1827 method A)

Environmental-Fluid Conditioning (Compatibility Testing)

Since the automotive, aviation, mining oil/gas industries continue to imposeproduct qualification requirements, we offer rubber and polymer testing toensure that these requirements are met. Because these industries requireproducts that must be able to perform under extreme temperature and fluidexposures, our testing is essential to the success of these products.

We have an extensive range of fluids available that can be applied over a widerange of temperatures, components and material samples. Our laboratoryaccommodates a variety of sample dimensions and various chamber sizes.
