In 2021, DLR Elastomer Engineering Ltd was formed following the successful acquisition and relocation of Elastomer Engineering Ltd into Dexine Leyland Rubber Technology Ltd (DLRT) at our Leyland Facility. DLRT was formed by the merger of Leyland Rubber Components and Dexine Rubber Technologies, both of which have 100+ years of history as rubber manufacturers.We are proud to call ourselves experts in the design, development and manufacture of specialized polymer products.Established in 1966, Elastomer Engineering was a UK based&nbsp;rubber molding&nbsp;company, delivering products in all commercially available rubbers and polyurethane products. As thermosetting elastomer manufacturers, we specialize in&nbsp;rubber-to-metal bonding&nbsp;and making parts from thermosetting rubbers.Today, DLR Elastomer is a highly experienced and reliable&nbsp;rubber sheeting, fabrications and molding company with materials science and manufacturing expertise from many different fields, combining them to produce bespoke rubber products.

Acrylonitrile butadiene rubber (NBR), usually shortened to nitrile or NBR, was developed in 1941 as the first oil resistant rubber. NBR rubber grades with high acrylonitrile content have better oil resistance, whereas low acrylonitrile content gives better low-temperature flexibility and resilience.

Perfluoroelastomers (FFKM) rubbers are fully-fluorinated fluorocarbon elastomers. They fill an important niche for applications involving aggressive chemicals at temperatures up to 325°C.

FFKM

Silicone rubber is a high-performance elastomer that is ideal for high and low-temperature applications. VMQ’s unique structure provides material flexibility, and it is consistent over a wide range of temperatures thanks to its chemical characteristics.

Fluoroelastomers or Fluorocarbons (FKM), widely known as Viton®, are among the most suitable rubbers for continuous use at temperatures of 200°C and up to 300°C for short periods. Viton® is a registered trademark of The Chemours Company. Various grades of Fluoroelastomer are available, depending upon which physical properties such as compression set, flexibility (as in diaphragms) or chemical resistance are required. Both copolymers &amp; terpolymers are widely used.

Natural rubber is the only non-synthetic rubber available on the market and has been in commercial use since the beginning of the 20th century. NR is extracted from the sap of the Hevea Brasiliensis tree grown in renewable plantations. One true advantage of NR is that it is fully biodegradable.

CR general-purpose rubber has an excellent balance of physical and chemical properties that make it suitable in a range of applications.

Ethylene Propylene Diene Rubber (EPDM) is a copolymer manufactured from ethylene, propylene, and a small number of diene monomers. A small number of diene monomers form unsaturated groups pendant from the main saturated chain. These diene monomers provide cross-linking sites that allow EPDM to be vulcanized.

EPDM

Hydrogenated AcryloNitrile Butadiene Rubber (HNBR) properties depend upon the acrylonitrile content and the degree of hydrogenation of the copolymer. They have somewhat better oil and chemical resistance than nitrile rubber and can withstand much higher temperatures.

HNBR

NBR 70 BL FDA R1 is a blue food quality metal detectable nitrile rubber (NBR). Specially developed rubber material for use in the food preparation industry. It is oil free, FDA compliant metal detectable rubber compound.NBR has moderate physical properties but good abrasion resistanceIt is extremely versatile, reliable and offers reasonable resistance to petroleum oil, crude oil, water, gasoline and some hydraulic fluidsOffering great abrasion and compression set resistanceNBR is a cost-effective sealing solutionBecause of this, NBR is a popular sealing material for a wide range of applications.

EPDM 80 B WRAS G1 is a polymer made from ethylene, propylene, and a small number of diene monomers. These diene monomers provide cross-link sites that allow EPDM to be vulcanized. A small number of diene monomers form unsaturated groups pendant from the main saturated chain. These groups facilitate cross-linking reactions that do not affect the integrity of the polymer backbone.EPDM rubber has excellent heat, ozone and chemical resistance propertiesEPDM also has good physical properties and is resistant to polar fluidsLow-temperature properties require the polymer to be amorphous and low on ethylene (speak to the expert)Good electrical properties require high ethylene to facilitate high doses of inert mineral fillers to give good electrical resistanceEPDM rubber can be compounded to provide excellent electrical resistance

Advantages Of CR Rubber

Disadvantages Of CR Rubber

As you may expect from its widespread use for underwater wear, including wetsuits and diving costumes, Neoprene® is water-resistant. However, whilst this is suitable for underwater clothing, Neoprene® also exhibits poor electrical properties.
