Materials Used in Rubber Molding Operations

When planning a custom rubber molding project, one of the main considerations is building materials. Our team has a wealth of knowledge and skills that can help customers choose the elastic body that suits their needs. Some of the questions we asked during the material selection process included:

  • What is the intended use of the final product?
  • What are the requirements for application?
  • Will the final product encounter any chemicals during its use?
  • Do you need specific material specifications, such as ASTM or Mil-spec?

The answers to these questions, among other things, help us identify potentially major options. Some of the most common materials used in rubber molding operations include:

EPDM rubber gaskets seals o-rings


EPDM has excellent UV resistance, aging resistance, high and low-temperature resistance, and is a very versatile material.

EPDM Rubber 2


Nitrile rubber has good oil resistance. Nitrile materials are used not only for petroleum, fuel, and chemical resistance applications, but also for applications that need heat resistance, abrasion resistance, water resistance, and gas permeability resistance.

FKM rubber gaskets seals o-rings


FKM is commonly used in mechanical seals, pumps, reactors, agitators, compressor housings, valves, meters, and other equipment. Commonly used as a seat, stem packing, diaphragm, and gasket.

SILICONE rubber gaskets seals o-rings


When it comes to extreme temperature, silicone rubber offers a great range of resistance in both hot and cold environments. In addition, silicone offers far superior tensile strength, elongation, tear strength, and compression sets in extreme temperatures than conventional rubbers.

In addition to temperature resistance, other advantages of silicone rubber include insulation from electricity, compression set resistance, and the ability to repel water.

NEOPRENE rubber gaskets seals o-rings


Neoprene has a wide range of uses, including rail transit, wire and cable, food preparation, and construction.

NR rubber gaskets seals o-rings


Natural rubber is not recommended for applications where the rubber part will be exposed to ozone, oils, or solvents.
