Type B durometers are used for hard elastomers, hard plastics, paper, fibrous materials and materials above 93A durometer hardness
. Type C durometers are used for medium hard materials, plastics and elastomers.
Established in January 2014 in Dubai Investment Park, GRI claims to be the first of its kind in the entire Middle East to offer a phenomenal range and capabilities in manufacturing of extruded, co-extruded and moulded products of EPDM (ethylene propylene diene terpolymer), neoprene, silicone, Viton and fluoro silicone rubber for aluminium architectural application that comprises multi durometer hardness
, multi material colour extrusion, profile pre-cut, TPE (Thermoplastic Elastomer), vulcanised frames, corners and various other combinations depending upon the customer requirements.
The newest product offerings add 60 and 70 durometer hardness
options to Dow's growing portfolio of fully and partially fluorinated liquid silicone rubbers, which it says can help designers develop more durable components for withstanding severe operating environments and can help fabricators achieve manufacturing improvements with automated processing, reduced labour costs, shorter cycle times, energy savings and reduced scrap rates.
The test compares the weight, durometer hardness
and the axial tensile strength after 112 days of exposure.
It is very desirable for material to show stable performance, including durometer hardness
and dynamic properties, across a wide temperature range.
* Durometer hardness
ranges from 45 and 60 [+ or -] 5.
Having a Shore A durometer hardness
of 35 +/- 5 and a 9% compression set figure, the gasket's shielding effectiveness is greater than 70 dB between 100 MHz and 10 GHz.
The new products included the company's two solid silicone grades, Elastosil R 401/10 and Elastosil R plus 43057/90, and highly transparent silicone prototypes of medium durometer hardness
that have been developed specifically for extrusion.
What: Durometer hardness
testers for plastic and rubber parts producers
The compound is said to combine an 89 durometer hardness
, as well as excellent mechanical properties, flow properties and transparency.
