  Description POM also known as Polyacetal and Delrin. This is highly crystalline thermoplastic with a high level of stability and rigidity as well as exhibits good sliding properties. POM-C has excellent sliding properties and good wear resistance, together with its other outstanding properties, POM-C is well suited for sliding applications with medium to high loads. This also applies to applications where high levels of humidity or wetness are to be expected. POM-C is not resistant to UV rays, UV rays, in combination with atmospheric oxygen, oxidize the surface, and discoloration occurs or the surface become matt. If the material is subject to the effects UV rays for a long time, it tends to become brittle.   Application Spring elements Bushes Gear wheels Sliding elements Insulators Pump components Casing parts Valve and valve bodies Counter parts Precision parts etc etc   Main Properties The main benefits of POM are High stability, rigidity and hardness. Good impact resistance even at low temperature. Low moisture absorption. Good creep resistance. High dimension stability. Good resistance to hydrolysis. Excellent Machineability. Good electric and dielectric properties. Suitable for food industries (physiologically safe).

  Description Polyurethane is an extremely versatile elastomer used in countless applications world wide. Polyurethanes mechanical properties can be isolated through creative chemistry which creates a number of unique opportunities with performance characteristics unequaled in any other material. It is our understanding of how to seize these opportunities which allow us to provide “Flexible Solutions Through Polymeric Innovation.” Short Production Lead Times: Compared to conventional thermoplastic materials polyurethane has a relatively short lead time with significantly more economical tooling costs.   Application Advantages of Polyurethane: Wide range of hardness:This classification of hardness of polyurethane relies on the prepolymers molecular structure, can be manufactured from 20 Shore A to 85 Shore D. High load bearing capacity: It has a high load capacity in both tension and compression. It may undergo a little change in shape under a heavy load, but will return to its original shape once the load is removed with little compression set in the material when designed properly for a given application. Color Ranges:  Varying color pigments can be added to it in the manufacturing process. Ultraviolet shielding can be incorporated into the pigment to provide better color stability in outdoor applications.

  Description PCTFE is a white translucent material which is very rigid, it has excellent resistance to cold flow, exhibits dimensional stability at a wide temperature range, has very low gas permeability and low moisture absorption properties, PCTFE is also FDA approved.   Application Application Advantages: Stress-crack resistance, High mechanical strength and low shrinkage rate at low temperatures provide excellent stability for valve seats. Excellent chemical resistance to all inorganic corrosive liquids. Practically zero moisture absorption. Excellent electrical properties maintained in high humidity. Application Limitations: PCTFE swells slightly in halocarbon compounds, ethers, esters and aromatic solvents.Although PCTFE has excellent chemical resistance, it is still less than that of PTFE. Usage: Cryogenicvalve seats High pressure gas seats and seals. Semi-conductor process components such as wafer boats. Sight Glasses and windows. Electrical components. Parts for high vacuum applications.

Description Perfluoroelastomers show ultimate performance among all elastomers. They are resistant to nearly every chemical class with some grades offering heat resistance over 300°C, this makes FFKM the material of choice for high demanding sealing applications.   Application Application advantages: • Excellent heat resistance • Resistant to almost every chemical class • Excellent outgassing performance in vacuum environments. • Wide temperature range -30° C to +300° C Application limitations: • Avoid low-molecular-weight, fully halogenated fluids and molten alkali metals.Strong oxidizing acids may causesome swelling • Helium permeability is slightly higher than fluoroelastomer compounds • Extreme high cost. Usage: • All areas where extreme critical application is required.

Description PET  stock shapes are of the semi crystalline type and have a high level of hardness, rigidity and stability with excellent sliding properties and low sliding abrasion. Because of its good creep resistance, low level of moisture absorption and excellent dimensional stability, the material is ideally suited for complex parts with the highest demands on dimension stability and surface finish. For the reasons mentioned above, only the semi crystalline type is suitable for sliding applications.  The wear resistance and sliding properties of PET-GL have been improved compared to pure PET by adding a special, homogeneously distributed solid lubricating agent.  The main benefits of PET are High stability, rigidity and hardness. Very good creep resistance and dimension stability. Very less sliding friction and sliding abrasion. Resistance to hydrolysis Physiologically safe Excellent stain resistance Better resistance to acids than PA & POM Good electrical insulating properties Resistant to high energy radiation (Gamma & X-rays) Colors: PET (natural, black), PET-GL light grey  PET has excellent sliding properties, very good wear resistance and, in combination with its other properties, is an excellent material for highly loaded sliding applications, This also applies to applications where high levels of humidity or wetness are expected.  Applications:  ratchet wheels, bushes, gears, sliding elements, insulators, casing parts, counter components, precision bearings, cam disks etc etc,

    Description PVC-U (Hard PVC) is an amorphous thermoplastic with no added plasticizer. It has high hardness and rigidity. According to DIN 16 927 the material is classified as normal shock resistant, however its toughness values border on being rated as highly shock resistant, which gives it a high degree of safety in regards to the design of components. PVC-U is a flame retardant material with an exceptional chemical resistance and also lower stress cracking. It shows high mechanical strength, tensile strength and works with a continues operating temperature of -15˚C to +60˚C. It can be easily glued and welded. PVC-U is not subject to any major sliding abrasion and is thus not suitable for use in sliding applications. PVC-U is resistant to acids, alkaline solutions, alcohols, oils, fats, aliphatic hydrocarbons and petrol. PVC-U is not resistant to benzole, chlorinated hydrocarbons, ketones or esters. In combination with strong oxidizing materials (e.g. nitric acid or chromic acid), there is a danger of stress corrosion cracking.   Application Pump parts Fittings Valve bodies Component parts in chemical plant construction Feed tables, machine and equipment coverings Gaskets Bearing cages Pipe lines Lamp boxes Parts in dental medicine etc etc   Main Properties The main benefits of PVC are:- Good insulation properties for electronics. High mechanical strength, tensile strength and hardness. Low water absorption. Excellent chemical resistance. Fire resistant. Easily thermoformed. Can be bonded. Good cutting properties.
