PLMPUR (TPU) green

PLMPUR is a thermoplastic polyurethane elastomer, with an excellent abrasion resistancelow compression set, outstanding tensile properties, and tear strength. PLMPUR is mostly used for U-cup seals, lip seals, wipers, and chevron packings, it may also be used for dampers and

other machined parts. It has a very good resistance against hydraulic fluids based on mineral oils, however, in applications with water-based fluids (e.g. HFA, HFB) and native liquids(vegetable oils) a temperature of 60C should not be exceeded

PLMPUR is produced by injection moulding and shows very good machinability.

PLMPUR-H (TPU) red

PLMPUR-H is a hydrolysis-resistant thermoplastic polyurethane elastomer. lt combines the

engineering properties of PLMPUR (outstanding physical properties) with a high chemical

resistance against a broad range of fluids. It is resistant against hydrolysis (degradation in water) which is otherwise rare when it comes to polyurethanes. E.g.it is stable in water up to +90C and has outstanding stability in mineral oil as well. Because of its resistance to hydrolysis PLMPUR-H can be used for water hydraulics and for applications in mining tunneling and manufacturing of presses. PLMPUR-H is particularly recommended for use in pure and seawater, for HFA and HFB fluids, and biologically degradable hydraulic fluids (vegetable oils and synthetic esters) and food articles. PLMPUR-H is in conformance with various food regulations and can be used for many food-, beverage-, and healthcare- applications

PLMPUR-H is produced by injection moulding and shows also very good machinability. 

PLMPUR-SL(TPU) grey 

PLMPUR-SL (TPU) has been optimized in regard to the tribological characteristics (friction and wear), achieved by the addition of a synergetic combination of solid lubricants. Compared to PLMPUR-H, PLMPUR-SL has superior sliding properties. This special material is therefore best suited for most severe applications in water hydraulics as well as in non-lubricated pneumatics.

PLMPUR-LT(TPU) blue

PLMPUR-LT is a thermoplastic polyurethane elastomer, that has been developed for low-temperature applications. The physical and chemical properties of PLMPUR-LT are similar to those of PLMPUR, but the minimum service temperature is extended to -50 C, For that reason, PLMPUR-LT should be used under severe climatic conditions and for applications in freezing plants.

PLMPUR-X (TPU)dark green

PLMPUR-X is a thermoplastic polyurethane elastomere and has a significantly higher hardness compared to the standard PLMPUR grade. The composition of the material provides outstanding friction and wear properties as well as high-pressure resistance. Therefore the material is well-suited for the use as a composite seal, for wipers working in heavy-duty applications as well as for engineered plastic parts that need high elasticity and superior resilience behaviour. Due to the exceptional extrusion resistance seals made of this material are working at higher pressure levels and larger clearances than those made of standard polyurethanes and PTFE compounds.

PLMPUR-XH (TPU) dark red 

Compared to the standard grade PLMPUR-H, PLMPUR-XH has a significantly higher hardness. The composition of the material based on special raw material provides outstanding friction and wear characteristics as well as pressure resistance.

PLMPUR-XSL (TPU) dark grey

Compared to the PLMPUR-SL standard material, PLMPUR-XSL has a higher hardness and therefore further improved sliding properties, PLMPUR-XSL has a better extrusion resistance than the standard material and therefore sealing elements of this material can be used at higher pressure.

PLMPUR-G(CPU)red

PLMPUR-G is a cast hydrolysis-resistant polyurethane elastomer with similar properties to PLMPUR-H especially regarding its chemical stability, Therefore PLMPUR-G can be used in the same hydraulic fluids as PLMPUR-H.
