Solid Rubber

Rubber is probably the most widely used gasket material. Rubber is offered in many different styles and grades to meet many applications’ needs. In addition, rubber is commonly available “off the shelf” in most styles, grades and thicknesses.

Synthetic rubbers are generally made from petroleum-based by-products. Alternatively, natural rubber is derived from latex from Rubber trees which are found in Thailand and Indonesia.

Common Solid Rubber Materials

Many rubber products are offered in standard commercial grades as well as high-grade. Generally, high-grade materials will have a higher percentage of the actual product (ie Nitrile) and may have a higher tensile strength and/or operating temperature range.

A list of the most commonly used rubbers and their characteristics are listed below.

Rubber	Durometer	Thickness	Temperature Range	Tensile Strength (PSI)	Overview
Butyl	40 - 80	.015-1.00	-40 - +225	1500	Excellent dielectric properties; low permeability to air and gases; moderate UV, ozone and oxidation resistance
EPDM	40 - 80	.015-1.00	-40 - +300	900	Excellent UV, ozone and oxidation resistance; also abrasion resistant
EPDM - FDA approved	40 - 80	.015-1.00	-40 - +300	900	FDA approved ingredients for use around food; white color
EPDM - NSF 61 Approved	40 - 80	.015-1.00	-40 - +300	900	NSF 61 approved for potable water applications
Epichlorohydrin	60-70	.015-1.00	-40 - +250	1200	High-end rubber; excellent resistance to oil and grease; broad operating temp range; broad chemical compatibility
Fluorosilicone	40 - 70	.015-1.00	-60 - +500	900	Excellent temp range; resistant to fuels and solvents; naturally resistant to ozone
Gum Rubber / Natural Rubber	40	.031 - 1.00	-60 - +220	2300	Good physical properties and low temp range; greater elongation than most rubbers; very resilient
Neoprene (Chloroprene)	30 - 80	.015 - 1.00	-40 - +200	500	Low cost, general purpose material; moderate oil, grease, solvent and chemical resistance
Nitrile, BUNA-N, NBR	30 - 90	.015 - 1.00	-30 - +220	850	Widely used for its resistant to most oil, grease, water and hydraulic fluid. It is also compatible with certain chemicals
