Rubber pad forming process, 1: bottom of the press. 2: lower die. 3: sheet metal. 4: rubber pad. 5: top of the press. Rubber pad forming (RPF) is a metalworking process where sheet metal is pressed between a die and a rubber block, made of polyurethane. Under pressure, the rubber and sheet metal are driven into the die and conform to its shape ...
Silicone rubber is used as an electrical insulator in power cables and cable joints. [18] [21] Silicone-insulated cables are advantageous in that they can withstand temperatures from -90°C to 200°C, and are highly flexible. These properties make them suitable for maintaining circuit integrity in the event of a fire. [22]
Pads or sheets of flexible materials such as elastomers, rubber, cork, dense foam and laminate materials. Elastomer pads, dense closed cell foams and laminate materials are often used under heavy machinery, under common household items, in vehicles and even under higher performing audio systems.

The actuation force is the force required to collapse the membrane of a rubber switch, and the contact force is the force required to maintain rubber-switch contact closure with a printed circuit board. Mathematically, this can be represented by: Snap ratio = (F1 - F2) / F1. where F1 is the actuation force, and F2 is the contact force.
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is required.
Elastomeric bearing pads, to serve as bridge beam supports heads. An elastomeric bridge bearing, also known as a pot bearing or elastomeric bearing, is a commonly used modern bridge bearing. The term encompasses several different types of bearings including bearing pads, bridge bearings, laminated elastomeric bearings, and seismic isolators ...
In continuum mechanics, an Arruda–Boyce model [1] is a hyperelastic constitutive model used to describe the mechanical behavior of rubber and other polymeric substances. This model is based on the statistical mechanics of a material with a cubic representative volume element containing eight chains along the diagonal directions.
Rubber elasticity is the ability of solid rubber to be stretched up to a factor of 10 from its original length, and return to close to its original length upon release. This process can be repeated many times with no apparent degradation to the rubber. [1] Rubber, like all materials, consists of molecules.
