Nowadays, vehicles must consistently handle high engine temperatures and varying weather climates. The growing demand for extended warranties and reduced emissions places a lot of added stress on the sealing process in the manufacturing stage too.

Unlike plastic components, the manufacturing of rubber parts requires a tailored approach to cope with the aesthetic and functional needs, as well as adhering to regulatory requirements. If you fail to consider this, vehicles will not perform at an optimum level and will be more susceptible to the elements.

From O-Rings capable of withstanding high pressures to water/dust ingress seals. Learn everything you need to know about choosing the best automotive sealing solutions. You may think automotive sealing solutions belong around the windows and doors of your vehicle, but they are used in various areas inside and outside of the car.

Please note that some materials within retrospective applications can be used across other automotive sealing applications. Please get in-touch to find out more. Within this blog we will cover 5 key automotive sealing solution applications:

• Interior cabin systems
• HVAC (Heating ventilation and air conditioning)
• Fuel tank systems
• Li-ion and electric battery
• Boot and tailgate systems

Interior cabin systems

EPDM sponge (Closed Cell) &#; Available in a wide range of densities and properties, ensuring optical application performance. EPDM foam sealing is considered one off the best options for weatherstripping vehicle interior cabins and cockpits, due to its good sealing properties against air, dust and water migration. It is also has resistance to ageing, UV, ozone and oxidation.

Ramsay have the manufacturing capability to manufacture a wide range of custom EPDM sponge automotive sealing solution products. Key competencies in the production off:

Nitto foam (Semi Closed Cell) &#; Nitto foams provide the ultimate in automotive sealing solutions. Nitto , 686 and are EPDM based foams, that have a semi -closed cell structure. Providing a watertight seal between 50 &#; 80 % compression. Nitto Foams are used in a wide range of interior cabin applications. Predominantly for interior trims, these include dashboard, centre consoles, glove boxes, speakers and grills.

This material offers superior durability and weather resistance, it also has excellent chemical resistance to acids and alkali&#;s. Nitto foams offer the best in durability and weather resistance, it is o- zone resistant, fungus free and has an excellent ageing performance ensuring it provides high performance Sealing, NVH, Acoustic and Thermal solutions

Ramsay have the manufacturing capability to manufacture a wide range of custom nitto foam automotive sealing solution products. Key competencies in the production off:

Superseal foam (Open Cell) &#; Superseal foams are water-repellent with good water sealing properties. Superseal Foam offers excellent sealing properties, with low water absorption, low air permeability and low compression hardness.

However, the real advantage of superseal is that it offers excellent light weighting whilst providing a good seal when compressed at 80%, it is also more price competitive when compared to other high-performance sealing materials/product.

HVAC (Heating ventilation and air conditioning)

Polyethylene foam (Closed Cell) &#; Polyethylene foam is also known as PE and LPDE foam. It is cost effective and rigid, providing excellent HVAC seals under little compression. It is also used for a variety of other automotive sealing solutions. The key advantage of Polyethylene foam is its strength and how lightweight it is comparable to heavier chemically formed foams.

Polyethylene foam gaskets and sealing are mainly used for evaporator units and A/C heater controller modules.

The smooth surface offers excellent consistency, gauge control and low water absorption and vapour transmission. Materials in this range are extremely durable and have exceptional, Ozone, UV, chemical and weather resistant which provide Acoustic, NVH, Thermal and High-Performance sealing properties.

Fuel tank systems

Neoprene blend (Closed Cell) &#; Neoprene EPDM Blend offers the best characteristics of both materials in terms of performance and price.

You will get efficient and thoughtful service from I-ECO.

Blend offers oil and petro-chemical resistance as well as offering excellent weatherproofing due to its resistance to ageing, UV, ozone and oxidation. This material provides an excellent seal under compression as well as thermal conductivity and NVH solution

With these material properties, Neoprene EPDM blend can be used for sealing, NVH and anti-rattle. For fuel tanks, tank harnesses, hoses and piping.

Nitrile rubber (Closed Cell) &#; Nitrile rubber is a synthetic rubber copolymer of butadiene and acrylonitrile, often referred to as NBR. It&#;s highly resistant to oils and fuels, and can cope with extreme temperatures ranging from -20 ˚C to + 100˚C.

It can be attacked by UV/ozone, so it thrives within the car mechanics as O-rings, fuel tank gaskets and seals.

Ramsay have the manufacturing capability to manufacture a wide range of custom solid nitrile rubber automotive sealing solution products. Key competencies in the production off:

Li-ion and electric battery

Silicone rubber/sponge (Closed Cell) &#; If you&#;re searching for a high temperature performance seal in the automotive industry, look no further. As an automotive seal, silicone offers strength, durability and brilliant resistance to heat (-60˚C to 230 ˚C). It also has outstanding weathering properties, UV and chemical resistance.

Dependant on grade, silicone rubber/sponge can provide an ingress protection of IP67. Ensuring high performance sealing for battery compartments.
