Common Materials Used in Rubber Injection Molding

Rubber injection molding is compatible with many thermoset elastomers and a variety of shapes and geometries. Materials are selected for specific characteristics, such as resistance to chemicals like oils or solvents, resistance to temperature damage, resistance to weathering and abrasion, and resistance to harsh environments. Mechanical characteristics like strength and elasticity, and MIL-SPEC or industrial standard requirements are also important.

At RD Rubber Technology, we often work with the following materials:

• Butyl: Durable and resistant to abrasion, wear, and tearing, also highly resistant to weather, ozone, polar solvents, alcohols, ketones, some esters, and some brake fluids.
• Ethylene Propylene Diene Monomer (EPDM): Excellent heat, UV, and weather resistance.
• Fluorocarbon (FKM/Viton): Extremely resistant to chemicals, including oils and fuels, and exhibits high-temperature stability.
• Fluorosilicone: High temperature stability and resistance to fuels and oils.
• Neoprene: Resistance to chemicals, ozone, and weathering.
• Nitrile Rubber (NBR): Resistant to chemicals, including fuel and oil.
• Silicone Rubber: Biocompatible, durable, and with excellent heat resistance.
• Urethane: Good elasticity, high degree of abrasion resistance.

Benefits of Manufacturing With Rubber Injection Molding

Rubber injection molding offers several advantages over other high-volume manufacturing methods. It’s incredibly versatile because when well-designed, cavity molds can be customized to a wide range of shapes and sizes for specialty applications.

Rubber injection molding does not require any preforms, which reduces labor, complications, and variability in product shape or weight. The process produces significantly less flash and has shorter production times than rubber compression molding.

Rubber Injection Molding Applications

RD Rubber Technology offers comprehensive custom rubber molding solutions for critical-to-function applications in demanding industries such as:

Rubber injection molding is well-suited for producing engineered rubber products such as seals, O-rings, gaskets, grommets, valves, diaphragms, poppet assemblies, plungers, latches, flappers, vacuum cups, boot pads, switches, covers, shells, housings, cases, connectors, and buttons.
