This is for one piece that is .25 inches in diameter & 12 inches long. ECCOSTOCK® 0005 is a translucent, low dielectric loss, cross-linked polystyrene stock that is impervious to moisture. It is a thermosetting plastic that will not flow when subjected to excessive heat and has excellent high and low temperature stability. The material can also withstand high voltages and is superior to most plastics when exposed to radiation. As the name suggests the dissipation factor is .0005 ECCOSTOCK® 0005 is particularly useful in RF and microwave applications. It has been used as the spacer in Type N connectors and for other machined parts in coaxial transmission lines. Machined parts are also used as waveguide supports, antenna insulators, and as complete microwave lenses. Other applications include material testing devices, surveillance equipment, radar windows, radomes and missile guidance system housings. Material Characteristics • Translucent, low loss, cross-linked, polystyrene stock • It is a thermosetting plastic that will not flow when subjected to excessive heat • Excellent high and low temperature stability • Contains no fungus nutrients • Pieces of ECCOSTOCK® 0005 can be bonded to itself or other materials Applications • ECCOSTOCK® 0005 has been used as the spacer in Type N connectors and for other machined parts in coaxial transmission lines • Machined parts are also used as waveguide supports, antenna insulators, and as complete microwave lenses. • Optical clarity and good mechanical properties have recommended this product for purely structural applications • ECCOSTOCK® 0005 is able to withstand high voltages for producing gap switch houses, capacitors and other components • High radiation resistance with little change in dielectric loss with exposures up to 1000m rads • Other applications include material testing devices, surveillance equipment, radar windows, radomes and missile guidance system housings Machining • ECCOSTOCK®0005 is easily machined. Tools should be kept very sharp. Feed rate should be initially low and then increased with emulsion type coolants recommended Typical Properties Temperature Range, °F (°C) -94 to 257 (-70 to 125) Short Term Service Temperature, °F (°C) <392 (200) Specific Gravity 1.06 Dielectric Strength, volts/mil (kv/m) 500 (20) Dielectric Constant, 60 Hz to 12 GHz 2.53 +/- .03 Homogeneity of Dielectric Constant ± 0.02 Isotropy of Dielectric Constant ± 0.01 Loss Tangent, 60 Hz to 12 GHz 0.0005 Volume Resistivity, ohm-cm Surface Resistivity, ohms/square Coefficient of Linear Expansion, °F (°C) Thermal Conductivity, (cal)(cm)/(sec)(cm2) 0.0003 0.87 Rockwell Hardness, M Scale 105 Tensile Strength, psi (kg/cm2) 11,000 (770) Flexural Strength, psi (kg/cm2) 17,000 (1,190) Modulus of Elasticity, psi (kg/cm2) 300,000 (21,000) Izod Impact, ft-lb/in (kg-cm/cm) of notch 0.4 (2.2) Water absorption, % gain in 24 hours at 25°C 0.003 %TML 0.29 Frequency Range 60 Hz to 12 GHz Description Frequency Range Key Features Thickness Service Temp Indoor/Outdoor Translucent, rigid, cross-linked polystyrene, does not flow 60 Hz to 12 GHz dk: 2.53, loss: .0005, low density, high tensile & flexural strengths, low water absorption .125" (.3cm) to 3.0" (7.6cm) -94°F to 257°F (-70°C to 125°C) In/Out
