PVC Nitrile Gaskets
PVC Nitrile Gaskets
PVC Nitrile Gaskets: Using a selection of worldwide suppliers for sponge and rubber gasketing materials, Advanced Seals & Gaskets Ltd are able to offer customers more choice when looking for a suitable product for their sealing and gap filling application, one of which includes PVC Nitrile Sponge Rubber.
PVC Nitrile sponge or PVC/NBR is manufactured in continuous rolls of material, at 1 meter wide and in a range of thicknesses from 3mm to 50mm, with a skin finish on both faces, however greater thicknesses may only be available as sheets . For non-standard thicknesses we can run the rolls through our state of the art splitting machines to create thicknesses from just 1.5mm with a cell/cell or skin/cell finish, all of which can be used for gasket conversion. By producing gaskets using our own facilities ensures that our high standards are maintained, in turn producing high quality gaskets consistently.
PVC Nitrile sponge gaskets are produced using drawings provided by our customers, with whom we work closely to ensure the final product is to their exact specification. From a simple rectangular picture frame gasket, to a more complex shape with cut-outs, notches or bolt holes - we can offer a solution. Whether it’s a one off sample or a multi-thousand batch run, we have a machine to quickly and accurately produce perfectly formed gaskets in a range of sizes, these include a number of presses, CNC and kiss cut machines. Our PVC nitrile gaskets can be produced plain, with a choice of finishes including foils, self adhesives or laminated to other materials, depending on the size and quantity of the gasket, they can be supplied as loosely packed parts, or kiss-cut on rolls.

What are PVC Nitrile Sponge Rubber Gaskets?
PVC Nitrile sponge rubber is soft and flexible closed-cell material, manufactured using a blend of Nitrile and PVC polymer compounds. This material can be used for shock or impact absorption, noise reduction and as a thermal insulator, being a closed-cell material it can also be used to produce gaskets for gas, moisture and air sealing. These PVC Nitrile gaskets can take the form of a strip or pad, but are generally an intricately cut shaped piece of the material placed between two surfaces to fill gaps and to create a low pressure seal preventing the leakage of liquids or gas and to seal against the intrusion of dust and debris when under compression.
Why use PVC Nitrile Gaskets?
There are many applications and industries which can utilise PVC Nitrile sponge gaskets as the material offers a number of properties making it suitable for use to create a watertight seal, as a thermal insulator and to reduce vibration and noise, as well as being impact, heat, UV, Ozone and flame retardant. PVC Nitrile gaskets are safe to use in building and construction applications as it is dust free, therefore will not affect the air quality and are easy to convert using a range of processes, ensuring and accurate cut and a perfect fit.
The Benefits of Using PVC Nitrile Sponge Rubber
- temperature range of -50°c to +116°c
- Excellent ozone, weathering and UV light resistance
- Can be used for thermal insulation
- Flame Retardant to Class O standards
- can be manufactured in either plain or self-adhesive backed
- prevents condensation and corrosion
- Closed cell structure prevents bacteria and mould build up
Other Grades of Sponge Available
There are different types and grades of sponge rubber available which can be cut into gaskets for use within many industries each with their own unique characteristics. Popular types of sponge rubber include:
EPDM sponge rubber is a high quality material with excellent weathering, UV and ozone resistance, making it ideal for outdoor sealing. EPDM sponge rubber rolls offer a wide operating temperature range, acoustic, thermal and vibration dampening properties and also good mechanical strength and abrasion resistant properties. Grades of EPDM include medium, firm, high temp and semi open cell.
Neoprene sponge rubber is a versatile material, featuring good resilience and resistance to UV and ozone. It has a working temperature range of -40ºc to +115ºc, good chemical stability, and good general resistance to oils and petroleum-based fuels.
Silicone sponge is a resilient material with high temperature stability, chemically inert and waterproof. Silicone sponge is closed cell, available in a range of densities (firmness) it has a number of features which make it suitable for outdoor sealing including Ozone, UV resistance and temperature flexibility, meaning it will not freeze/crack.
Viton sponge is another closed cell variety of sponge rubber offered by ASG. It is manufactured with skin on both faces which increases its tear resistance. It has a wide working temperature range of -25°C to +204°C and good resistance to hydrocarbons, oils, fuels, lubricants, acids, weathering and ozone.
Poron sponge is closed cell polyurethane sponge rubber, which offers excellent compression resistance, good chemical resistance and longevity. This material is low out-gassing, non-fogging and will not become brittle and break down over time.
Industrial sponge rubber is a high quality, open cell natural sponge rubber. The open cell structure enables excellent compression recovery, but also to form around uneven surfaces, limited absorption and circulation of gas and liquids if required. Its is an excellent choice of material for us as protective sponge, expansion joints and anti-vibration applications.
Advantages of using PVC Nitrile Gaskets
The first advantages of PVC Nitrile is that it is manufactured in a range of thicknesses, which means many standard thickness gaskets can be cut within a minimal time frame, the material is easy to split and convert so if bespoke thicknesses or cut products are required, these can be turned around fairly quickly.
PVC Nitrile holds adhesives well and therefore we can offer our gaskets plain or laminated with one of many adhesives or foils in order to securely hold the gasket in situ. PVC Nitrile sponge gaskets offer moisture, flame, UV and Ozone resistant properties which prevents condensation, corrosion and the growth of bacteria, rot and fungus.
This material has some resistance to chemicals, grease and oil, combined with a working temperature range of -50°C to 116°C and is flammability tested to meet Class O specifications, meaning the material doesn’t burn and flame spread is reduced making it suitable for use in HVAC, refrigerators, building & construction, sealing and pipework insulation.
