Ecopur is a thermoplastic polyurethane elastomer, which has an unusually high abrasive resistance, low compression set, high physical properties and tear strength. In sealing technology Ecopur is mostly used for U-rings, lip seals, wipers and chevron packings, but it may also be used for dampers and other machined parts. Products made from this material can be used in mineral oil, in water up to 40°C and in bio-degradable hydraulic oils like vegetable oils and synthetic esters up to 60°C (in these hydraulic fluids its better to use H-Ecopur instead of Ecopur). Depending on the seal design and the installation housing seals made of Ecopur can be used up to 400 bar (for higher-pressure anti-extrusion-rings are necessary).

H-ECOPUR (TPU) red
H-Ecopur is a hydrolysis-resistant thermoplastic polyurethane elastomer. It combines the engineering properties of Ecopur with a high resistance to hydrolysis (hydrolysis is degradation in water) which is otherwise rarely found in polyurethane?s. It is stable in water up to +90°C. Because of its resistance to hydrolysis H-Ecopur can be used for water hydraulic and for applications in mining, tunnelling and manufacturing of presses. H-Ecopur is particularly recommended for the use in pure and seawater, for HFA and HFB fluids and biologically degradable hydraulic fluids (vegetable oils and synthetic esters) and food articles. H-Ecopur is KTW approved and meets the FDA standards.

T-ECOPUR (TPU) blue
T-Ecopur is a thermoplastic polyurethane-elastomer, which is modified for deep temperature applications. The properties of T-Ecopur are similar to those of Ecopur, but the minimum service temperature is extended to -50°C. For that reason T-Ecopur should be used under severe climatic conditions and for applications in freezing plants.

ECORUBBER 1 (NBR) black
Ecorubber 1 is an elastomer based on acrylonitrile-butadiene rubber which is used for U-rings, chevron packings, special seals and various components. This material has a good resistance to mineral oils and greases and HFA, HFB and HFC pressure fluids. However, the material is not resistant to glycol-based brake fluids, HFD fluids, aromatic fluids (such as benzene), esters, ketones and amines or concentrated acids and bases.
ECORUBBER-H (H-NBR) black
Ecorubber-H is a hydrogenated or saturated acrylonitrile-butadiene rubber, which is suitable for applications in aliphatic hydrocarbons like propane or butane and mineral oils and greases (for short times up to 170°C) and also for sulfonated crude oil. Furthermore, it can be used in many diluted acids and bases and salt solutions even at elevated temperatures and in glycol-water mixtures. Ecorubber-H is not compatible with fuels with a high content of aromatic hydrocarbons (premium blend petrol), gasoline?s (petrol / alcohol blends) ketones, esters, ethers and chlorinated hydrocarbons like trichloroethylene and tetrachloroethy-lene.

ECORUBBER 2 (FPM, FKM) brown
Ecorubber 2 is an elastomer based on fluororubber (VITON: registered trade name of Du Pont) which can be used for U-rings, lip seals, chevron packings, wipers and special seals. Its outstanding properties are high resistance against heat, weathering, ozone and many chemical ingredients. Ecorubber 2 is compatible with mineral oils and greases containing sulphur, HFD pressure fluids (nearly all phosphate esters and chlorinated hydrocarbons), crude oil and sour gas. Ecorubber 2 is not resistant against anhydrous ammonia, amines, ketones, esters, hot water and low molecular weight organic acids.

ECOSIL (MVQ) reddish brown
Ecosil is a silicone rubber, which can be used for O-rings, gaskets and special seals. Owing to the poor mechanical properties, which are noticeably lower in comparison to other rubbers, Ecosil is mostly used for static (non-moving) applications. Ecosil is highly resistant against weathering, ozone and ageing. The compatibility with mineral oils depends on the content of aromatic hydrocarbons in the oil.

ECOFLON 1 (PTFE-virgin) white
Ecoflon 1 is a thermoplastic on the basis of polytetra-
fluoroethylene that is used for back-up rings, chevron packings, O-rings, rotary seals and gaskets. Ecoflon 1 has the widest application range of all sealing materials. Seals made of Ecoflon 1 will only be attacked by molten alkali metals and elementary Fluor at high temperatures. Using PTFE seals, it should be noted that creeping occurs at relative low loads (pressures).

ECOFLON 2 (PTFE with fillers) grey
Ecoflon 2 is a polytetrafluoroethylene filled with glass fibres and molybdenum disulphide and can be used for U-rings, glide (slide) rings, anti-extrusion rings back-up, for chevron packings and guide rings. Because of its special composition, Ecoflon 2 has good physical properties and distinctly better creep behaviour than virgin PTFE. The chemical resistance is similar to virgin PTFE; some ingredients can cause destruction of the fillers.

ECOTAL (POM) black
Ecotal is a semi-crystalline polyacetal-copolymer which is used for anti-extrusion rings, guide ring bushes, scrapers and for precision-machined parts with tight tolerances. Ecotal is one of the most important engineering thermoplastics with good physical properties, low water absorption and good chemical resistance. Ecotal can be used in mineral oils, in water-based fire-resistant hydraulic fluids (HFA, HFB and HFC fluids). Concentrated acids and bases will attack and destroy it.
