NE 501 - Neoprene® Rubber - Chloroprene (CR)

Rubber Neoprene Sheets
 Recommended for gasoline and no-aromatic solvents. Attacked by strong oxidizing acids, esters, ketones, chlorinated aromatic and nitro hydrocarbons. Excellent resistance to oils, ozone, sunlight and aging.
Durometer Range (Short A) 20 to 95
Tensile Range (psi) 500 to 3000
P x T max 15000
Resilience Rebound Excellent
Abrasion Resistance Excellent
Oil Resistance Fair
Temperature Tolerance (°F) -30° to +250°

NE 503 - Ethylene Propelyne Rubber (EPDM)

Rubber EPDM Sheets
 Excellent aging and ozone resistance. EPDM is the preferred rubber material for steam. Oil and solvent resistance is poor but is fairly good in ketones and alcohols. Not recommended for food applications or exposure to aromatic hydrocarbons.
Durometer Range (Short A) 30 to 90
Tensile Range (psi) 500 to 2500
Resilience Rebound Good
Abrasion Resistance Good
Oil Resistance Poor
Temperature Tolerance (°F) -30° to +350°

NE 504 - Synthetic Rubber (SBR)

Rubber SBR Sheets
 Satisfactory for most moderate chemicals and wet or dry organic acids. SBR is not recommended for ozone, strong acids, oils, grease, fats and most hydrocarbons.
Durometer Range (Short A) 30 to 100
Tensile Range (psi) 500 to 3000
Resilience Rebound Good
Abrasion Resistance Excellent
Oil Resistance Poor
Temperature Tolerance (°F) -30° to +225°

NE 505 - Nitrile / Buna N Rubber

Rubber BUNA Sheets
 Number one inexpensive choice for sealing petroleum, oils, and solvents. Nitrile should not be used in highly polar solvents such as acetone, and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
Durometer Range (Short A) 20 to 95
Tensile Range (psi) 200 to 3000
Resilience Rebound Good
Abrasion Resistance Excellent
Oil Resistance Good to Excellent
Temperature Tolerance (°F) -30° to +250°

NE 506 - Natural Gum Rubber (NR)

Natural Gum Rubber Sheets
 Excellent tensile, elongation, tear resistance and resilience. It has good abrasion resistance and excellent low temperature flexibility. It has poor resistance to ozone, oxygen, sunlight and heat. Not recommended for solvents and petroleum products.
Durometer Range (Short A) 20 to 100
Tensile Range (psi) 500 to 3500
Resilience Rebound Excellent
Abrasion Resistance Excellent
Oil Resistance Poor
Temperature Tolerance (°F) -60° to +175°

NE 509 - Silicone Rubber

Silicone Rubber Sheets
 Extreme low temperature properties. Highly resistant to oxidation and ozone. high resilience and low compression set. Generally attacked by most concentrated solvents, oils, and concentrated acids, however flourination increase chemical resistance.
Durometer Range (Short A) 30 to 90
Tensile Range (psi) 200 to 1500
Resilience Rebound Good
Abrasion Resistance Fair to Poor
Oil Resistance Fair to Poor
Temperature Tolerance (°F) -60° to +450°

NE 510 - Viton® Rubber

Viton Rubber Sheets
 One of the most expensive rubber materials due to its high temperature properties. Resistance to wide range of oils. Not recommended for ketones, low molecular weight esters and nitro containing compounds.
Durometer Range (Short A) 60 to 90
Tensile Range (psi) 500 to 2000
Resilience Rebound Fair
Abrasion Resistance Good
Oil Resistance Excellent
Temperature Tolerance (°F) -10° to +450°
