Material Grades

Flame Retardant Silicone Rubber

Adpol’s 40 years of experience manufacturing products for the aerospace industry means that we have a great deal of experience with Flame Retardant Silicone Rubber Compounds.

Silicone naturally is self extinguishing, and most of our general purpose grades meet UL94HB. But in certain specialist applications such as aerospace, rail and other mass transit even higher standards of self extinguishing and low smoke emissions are required from Flame Retardant Silicone Rubber.

Adpol manufactures in a number of Flame Retardant Silicone Rubber grades that meet UL94V0, ABD0031 and BS6853 and the halogen, toxicity and smoke emissions standards of the vast majority of airlines and train mass transit operators across the world. These compounds are available in a range of hardness’s and can be colour matched to your project requirement. We operate to the AS9100 quality systems and traceability levels required for products in these specialist sectors.

Adpol extrudes custom Flame Retardant Silicone Rubber seals that are often used as door, seat or bulkhead seals, either supplied as extruded profiles ( P tapes, D Profiles, e profiles , fabricated complete Silicone Rubber Gaskets, Silicone Rubber Sheeting and Strip, gaskets punched from sheet, or moulded silicone rubber parts, and adhesive backed if required

From drawing to sample for testing generally only takes a 2 – 3 weeks and costs £175 – £250

Weather Resistant Rubber

Weather Resistant Rubber

Silicone Rubber is by some way the most weather resistant polymer and an excellent choice if you need a good seal in any application likely to see tough environmental conditions.

Silicone Rubber is an extremely versatile material offering excellent technical properties in harsh conditions. Silicone Rubber is highly resistant to UV light, Ozone, oxygen, salt, mold and mildew, and the general aging affects of weather. Other rubbers can harden and crack over time and support organic growth, you see this sometimes on old window seals which can be EPDM

There have been many tests over the years to demonstrate this, including control samples of Silicone Rubber being subjected to the extremes of the Arizona desert or deep Atlantic oceans for years without any significant loss in technical performance.

Adpol can help you develop the ideal seal for your application in weather resistant Silicone Rubber, as we have with many longstanding customers over the years. Please don’t hesitate to contact us to discuss your requirements, we are here to help.

Low Temperature Rubber Seals

Low Temperature Rubber Seals

Adpol can manufacture custom seals designed to operate as low as -100 degrees C working with you to ensure the size, hardness, colour and other properties like tear strength and chemical resistance are exactly what you need

Rubbers harden as the temperature drop, Silicone Rubber performs best at extreme high and low temperatures. Our general purpose silicone (food and medical grade) will operate down to -40/-60 area without much problem. If you need extreme low temperature resistance we have a specialist grade designed to operate at -100. All silicones also offer excellent resistance to mould, mildew and microbiological growth

We can extrude tube, cord or profiles that can be cut and press joined into O rings or picture frame seals, mould parts, and can have gaskets cut from flat sheet for you

We have many years experience in this sector and would be very happy to work with you every step of the way to help you get exactly the seal you need. Please get in touch to discuss this further

Thermally Conductive Silicone Rubber

Thermally Conductive Silicone Rubber

Adpol can mould and extrude in a  grade of thermally conductive Silicone rubber which offers performance approaching copper loaded silicones, but at a fraction of the price.

Self Lubricating Rubber

Self Lubricating Rubber

Adpol can mould self lubricating Silicone Rubber parts that can operate at extreme high and low temperatures and offer many significant performance advantages over standard Silicone.

Through the addition of a special additive the Silicone exudes surface lubrication over time giving an extremely low friction surface. This offers many advantages over standard Silicone which may become tacky and stick against other surfaces, or itself.

Custom parts can be moulded or gaskets can be cut from moulded sheets in various thicknesses. We developed and have been working with this compound for many years. For technical advice, quotations or samples please get in touch and we’d be very happy to assist.

DTD Specification Silicone Rubbers

Adpol has been extruding and moulding in many different rubber grades since 1974 for Military, Aerospace and transport applications and is well versed in some of the DTD and other material specifications on drawings for rubber parts.

Common specifications that are still used are DTD 5531 DTD 818 and DTD 5582. Often quoted with prefixes after the main code which are important as these will denote the hardness and other unique performance factors.

Many drawings still call for DTD specifications and overlooking the specific requirements of the standard quoted can be dangerous. Adpol can source and manufacture in rubber grades that are either designed to meet, or tested to the required DTD specification with full certification and traceability up to our AS9100 quality standard.
