To respond to requests from engineering companies at the cutting edge of their technologies, DP Seals is continuously investigating new rubber compounds through its on-going R&D programme.
Using specially developed test moulds, DP Seals investigates material flows, out gassing, residues, etc., to ensure it knows not only the material's design performance but also its moulding characteristics.

| The advantages of hydrogenated nitriles (HNBRs) in the oil and gas industries are well understood. In particular, its hydrogen sulphide resistance has allowed wide adoption in many crude oil applications. The addition of carboxylation signifdicantly imroves the abrasion resistance making it one very tough material. |

Teflon-coated rubber has been around for some time but has problems of flexibility and flaking. However, using nano-particle size Teflon (PTFE - Poly Tetra Fluoro Ethylene) as a filler in fluoroelastomers shows immense promise:
 |
adding nano-fill Teflon significantly reduces friction with none of the side-effects of coatings, making it ideal for rotating seals in automotive, aerospace, oil and gas applications. |
|
nanotech rubber also exhibits reduced permeability, offering reduced emmissions to automotive manufacturers. |
|
because nanotech rubber is available in high-purity blends, it can be considered for semi-conductor manufacturing and food processing applications. |
Early indications are that it moulds well.

Fluoroelastomers offer excellent high temperature performance but perform poorly at low temperatures. Using special low-temp fluoroelastomers compromises high-end performance.
Silicone fluoroelastomer offers performance down to -50°C without top-end compromise. One area of particular interest is that it should provide much improved metal bonding capability, allowing fluoroelastomers to be used in fuel applications in arctic environments.
The adition of silicone should also upgrade the flouroelastomer's chemical resistance - particularly to polar solvents and new generation oil additives. It also offers improved steam performance, where conventional fluoroelastomers are subject to absorbtion with loss of mechanical performance, such as compression set.
