Cast Epoxy Rod Products
Maryland Plastic Products cast epoxy rod products are made from selected raw materials and are manufactured under strict quality control conditions. Their excellent electrical, mechanical and chemical resistant properties make them especially useful for resistor bobbins, component shells, coil forms, spacers, gears, slip rings, chemical pump, sampling cells, switch parts and many other applications. Normal outside diameter tolerance is +/-0.010". Our cast products are classified into four major types.

| RESIN TYPES |
TYPE I |
Unmodified anhydride cured epoxy products comprise a group that include MPC 4264 Amber, MPC 4265 Yellow, MPC 4274 Green and MPC 4278 Black. These products can be modified with fillers and other coloring pigments. Certain fillers will tend to raise the heat distortion point, reduce the coefficient of linear thermal expansion and improve thermal conductivity. This class has its greatest use as rod stock from which various forms are machined. |
| |
TYPE II FILLED |
MPC 5479 Black, MPC 5230 Black and MPC 5231 Yellow are filler modified anhydride cured products for use where a higher heat distribution and improved thermal conductivity is needed. |
| |
TYPE II HEAVY FILLED |
MPC 5171 Black can be used where a high heat distribution and end operating temperature of 200°C (392°F) are needed. This product may be easily machined. |
| |
TYPE II HEAVY FILLED
(Self Extinguishing) |
MPC 4289 is a high heat distortion and high operating temperature cast products. This material is available as a filled black product only. It may be machined or ground into many forms and can be operated at temperatures to 200°C (392°F). MPC 4289 is self-extinguishing. Tested in accordance with ASTM D635, with MIL-I-16923E and with MIL-T-27A. |
