Our materials specialists are able to perform a range of testing services to ensure quality and optimal performance.
Whether in-house testing or field trials, we are able to reproduce ideal and worst-case operating conditions, recording seal integrity, as well as monitoring pressure, speed, temperature, and a number of other performance factors.
Hallite Seals test and development facilities include:
- Friction And Leakage Test Rigs*
- Hydraulic Cylinder Test Rig*
- High Pressure Pulse Test Rig
- Finite Element Analysis*
Analytical testing performed by our laboratory includes:
- Chemical composition
When required, we also design product test stands.
Our laboratory uses a robust spectrum of plastic and elastomer test methods to ensure that material properties meet specifications. Conducted applicable standards such as ASTM, DIN, ISO, JIS; these tests include:
|Hardness||Durometer testing for control purposes, since no simple relationship exists between hardness and any fundamental physical property.|
|Tensile properties||Physical properties for tensile strength, ultimate elongation and modulus (tensile strength at a given elongation).|
|Thermal properties||Measures the performance of the material in a broad range of temperatures considering transition temperatures, coefficient of thermal expansion, and thermal stability.|
|Deflection temperature||A comparison of the relative behavior of various materials.|
|Compressive properties||Useful in determining specifications for different grades of materials, and in conjunction with other data to determine overall strength.|
|Specific gravity||The ratio of the density of a material to the density of a reference substance, generally water. It is used as a quality assurance measurement to assure lot-to-lot consistency.|
|Tear resistance||A relative measure of a material’s resistance to tear.|
|Compression set||A measure of a material’s retention of elastic properties, particularly useful with squeeze-type seals.|
|Immersion testing||Provides insight regarding the effect of a particular medium on a specific material.|
|Heat aging||Used to determine a material’s deterioration due to dry heat.|
|Adhesion||Primarily a quality control test for coating quality and application.|
*Capable of using high water-based fluids (HFA).
