Neoprene Rubber: Types, styles, forms and where they're used.
Author: Kurt Harding
Neoprene Rubber is a general purpose grade of rubber. It’s versatile and is compatible with quite a few different fluids and chemicals. Neoprene Rubber is also very economical and forms the basis of a large number of different types of materials and products.
Neoprene’s formal designation is Chloroprene which is sometimes shortened to CR (its official ASTM designation). If you do see CR Rubber written on a drawing or specification, chances are they mean Neoprene. From there, though, there’s a lot of different types, styles, and grades available.
At Swift, we try to offer a comprehensive range of Neoprene materials. Below is a summary of what we currently have in stock. All of these are carried in a selection of sizes and can be provided in small or large quantities, to suit the needs of your job.
Neoprene Rubber Sheet is probably the most popular form of Neoprene. This is due to its combination of all-around performance and economic pricing. Our standard grade of Neoprene Rubber is black in colour, withstands temperatures up to 100°C and has a Shore Hardness of 60 (±5) Durometer. It is used indoors and outdoors as it has good UV resistance.
Applications for Neoprene Rubber Sheet
- Oil seals and gaskets
- Marine gaskets
- Skirts and liners
- Sealing strips
- Rubber curtains
- Floor matting
- Bumpers and protective linings
- Sealing refrigeration units
- Wipers and packers
- Drain and roof sealing
- General rubber sheet applications

Neoprene Rubber Strip is made from our Neoprene sheet that is cut into convenient, strip rubber form. It has the same all-around performance of the sheet and is available in a large selection of thicknesses and widths. Neoprene Rubber Strip is non-adhesive as standard but one can be added upon special request. All standard sizes of our Neoprene Strip are available by the metre.
Applications for Neoprene Rubber Strip
- Making seals and gaskets for water pipes and tanks
- Floor protection and anti-slip strips
- Bumper strips and protective linings
- Seal strips for gutters and roofing
- Sealing around sheds and metal sheeting
- Sealing of refrigeration fluids and in heating, air conditioning or ventilation systems
Technical Properties of Neoprene Rubber Strip
Since it is cut from our Neoprene Sheet, technical details are exactly the same for both products.
Neoprene Sponge has many of the same all-around performance properties of Neoprene Rubber with some important differences. Being a sponge, it is, of course, lower density but will still create water-tight and air-tight seals. Neoprene Sponge has good resistance to oil and UV as well as aging so it offers reliable, long-term performance. Neoprene Sponge is black in colour and is not adhesive as standard (though this can be arranged on request).
Applications for Neoprene Sponge
- Automotive seals
- Low compression gaskets and seals
- Cushioning pads for equipment and furniture
- Acoustic insulation
- Anti-vibration pads
- Oil seals
- Void fillers
- Gap filling and sealing
|Continuous Operating Temperature||80°C|
|Hardness||25 ±5 HS (C Type)|
|Density||160 kg/m³ (±30)|
|Water Absorption||0.5% Maximum|
|Compression Set||25% Maximum|
Adhesive Neoprene Sponge Tape is a convenient and cost-effective way to seal many low pressure applications. It is made from closed cell Neoprene rubber sponge with a peel-off adhesive on one side. This sponge will create a water-tight seal at just 10% compression which makes it ideal for when you’re working with low bolt loads or narrow flange faces (like around windows). Adhesive Sponge Rubber Neoprene Tape has excellent resistance to oil, weathering, and UV and is used indoors or outdoors in temperatures up to 105°C.
Applications for Adhesive Sponge Rubber Neoprene Tape
- Sealing doors and windows around the home, in vehicles or in marine applications
- Sealing joints in metal sheet (such as those on sheds, garages or patios)
- Window sealing and glazing
- Sealing light fittings
- Marine applications
- Automotive sealing applications
- Sealing and weatherproofing electrical boxes
- Hatch covers and formed in place gaskets
- High compression gaskets for narrow and/or irregular flange faces
|Backing||Neoprene Closed Cell Sponge|
|Continuous Operating Temperature||-15°C to +105°C|
|Hardness||50 Shore 00 (Average)|
|Adhesive Strength||980 g/cm|
|Water-Tight Seal||Achieved at 10% Compression|
|Flame-Retardant||Yes (Federal Motor Vehicle Safety Standard USA)|
