Tight Tolerance Rubber Sheet

Fabric reinforced high temperaturesilicone rubber sheets and strips.

Tight tolerance rubber sheet.

Tight tolerance hardened multipurpose 4140 alloy steel sheets and bars. Use them as flange gaskets and anywhere heavy compression would squeeze nonreinforced silicone rubber out of place. Relatively new liquid silicone rubber sheet lsr is cast and cured into thin gauge continuous rolls from 010 to 032 thick in 36 widths. Tolerances because of the nature of rubber and other flexible materials tolerances need to be looser than sheet metal tolerances.

Also known as flat stock the thickness on these sheets and bars is held to a tight tolerance. Rubber tolerances rubber tolerances all the good stuff about rubber its flexibility elasticity its malleability and fact that the material can flow into complex unusual shapes during moulding also means that it is inevitably more difficult to control than other materials. The most commonly available lsr sheet materials are provided in 10 to 40 durometer shore a. The rubber manufacturers association rma has developed tolerance tables with ranges to provide communication between user and provider across a wide range of industries.

The rubber slitter is designed to cut very dense rubber and plastic sheeting. Model rs2 is equipped with a high torque motor and is designed with a very low knife speed to keep friction and heat build up to a minimum. All of our rubber sheeting products meet rma standard specifications. You can also consult the rma article on factors affecting tolerances of molded rubber products.

Lsr compounds have a platinum cure system which decreases out gassing and makes these silicone products more friendly to electronic medical and optical applications. With thousands of sheet rubber formulations you can order the materials you need for any environment or application including products that meet dod and military ams astm nse nsf fda and many more. Because metal parts support tight tolerances it s assumed incorrectly that rubber also supports a high degree of precision. One layer of fiberglass cloth is inserted between two layers of silicone rubber to give these sheets and strips the strength to stand up to high stress and flex.

It is available with a base plate or strip gauge to cut strips with a tight tolerance. That s because rubber is more sensitive to environmental conditions such as heat cold and humidity. However very tight tolerances can also be met. These are helpful when designing and producing a part.

Parts requiring extremely tight tolerances may need class a hardened steel tooling or water jet cutting vs. Hardened multipurpose 4140 alloy steel bars.
