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.

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

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.

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

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

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

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.

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.

DLR Elastomer Engineering Ltd Sorbothane - Durometer 50 (Shore 00) is one of our polyurethane products. Sorbothane provides good vibration isolation and vibration damping characteristics, making them a very effective acoustic damper. This material can also be bonded to other materials such as PTFE &amp; metals.Sorbothane has a superior damping coefficient, over a very wide temperature range, compared to any other polymerSorbothane’s operating temperature range is -20° to +160° Fahrenheit (-29° to 72° Celsius)Unlike fluid-based shock absorbers or foam products, Sorbothane absorbs shocks efficiently for millions of cyclesSorbothane eliminates the need for metal springs to return the system to its equilibrium position after absorbing a shock

EPDM 50 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

CR 60 B 3 F1 [C5985] general-purpose rubber has an excellent balance of physical and chemical properties that make it suitable in a range of applications. Whilst it may only have a moderate resistance to petroleum-based oil and fuels, CR has a much better chemical, oil, ozone and heat resistance than natural rubber, despite the lower level of physical properties. One major benefit of Neoprene® rubber is that by nature, CR rubber is one of the few self-extinguishing rubbers, which means it is flame resistance. Additionally, its gas permeability is relatively low. For industrial applications, Neoprene® gives excellent rubber-metal bonding and has good levels of rebound resilience. This compound lends itself to being fabricated into many different products with fabric reinforcement.Outstanding physical toughness Wider short- and long-term operating temperature range than general-purpose hydrocarbon elastomersResistance to hydrocarbon oils and heat (ASTM D2000/SAE J200 categories BC/BE)Resistance to ozone, sun and weatherBetter flame retardant/self-extinguishing characteristics than exclusively hydrocarbon-based elastomersAs with all elastomers, properties inherent in the base polymer can be enhanced or degraded by compounding with additional ingredients
