Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene.  

Being hydrophobic, non-wetting, high density, and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it's perhaps best known for its non-stick properties.

Pulim Sealing Solutions Co. Ltd. offers a wide range of standard compounds, the majority of which have been developed, and are produced, in our own production plant.

Pulim Sealing Solutions Co.td. is specialised in advanced engineered plastics products. The offer goes from turned, milled and moulded parts to advanced and standard engineered plastic parts, using an in-house developed and produced range of materials Thermoplastic elastomers demonstrate the characteristic properties of elastomers over a wide temperature range, but with the processing behaviour of thermoplastics. They can be melted at high temperatures and can be processed with traditional thermoplastic processing techniques. Thermoplastic elastomers are soluble and they generally swell less in comparison to their chemically crosslinked equivalents. Thermoplastics can be melted. They are polymer materials, which are essentially harder and rigid at their application temperature compared to elastomers. Depending on the chemical structure, the properties vary from hard, to stiff, to ductile and flexible. Due to the morphological structure, extensive stretching is non-reversible and moulded parts remain deformed, Thermoplastics are therefore called Plastomers. Engineering Thermoplastics are applied in the sealing technology for backup rings and guide rings, bearing bushes, etc.

PLMFLON-1 (white)

PLMFLON-1 is based on polytetrafluorethylene. Due to its composition, it has the widest application range of all sealing materials, it has an outstanding chemical resistance and is only susceptible to molten alkali metals and elementary fluorine at high temperatures. PTFE has a tendency to creep and can absorb relatively low-pressure loads. UTECFLON-1 is suitable for applications in contact with foodstuffs and is also used in many applications in the healthcare and pharmaceutical industries.

PLMFLON-2 (grey) 

(PTFE+ 15% glass + 5% Mos2)

PLMFLON-2 is a PTFE filled with 15% glass and 5% MoS2 to improve its compression strength, extrusion resistance and sliding properties in comparison with PTFE-virgin.

PLMIFLON-3 (brown)

(PTFE+ 40% bronze)

PLMFLON-3 is a PTFE filled with 40% bronze in order to improve its compression strength and has improved thermal conductivity as well as excellent wear resistance compared with PTFE-virgin Bronze-filled PTFE has higher friction and poorer chemical resistance than other filled PTFE compounds. 

PLMFLON-4 (black)

(PTFE + 20% carbon)

PLMFLON-4 is a PTFE filled with 20% carbon, which gives it excellent compression strength, good thermal conductivity and low permeability, Carbon-filled PTFE is less abrasive than glass-filled PTFE and has excellent wear and friction properties especially when combined with graphite.

PLMFLON-5 (Cream)

(PTFE+10% Ekonol)

PLMFLON-5 is a PTFE filled with 10% Ekonol. lt has good wear and extrusion resistance, especially in dry running conditions .it has similar chemical resistance and can be used at the same temp. range, as pure PTFE, especially in rotary applications at high speeds. it should not be used in hot water.

PLMFLON-6(Tan)

(PTFE+10% PEEK)

PLMFLON-6 is a PTFE filled with 10% PEEK. It has good chemical resistance, high creep strength and high wear resistance, PLMLFON-6 is mainly used for applications requiring very high resistance
