Polyurethanes are a family of elastomers, an artificial rubber which combines the strengths of a plastic, with the elasticity of a rubber.

Polyurethane

Polyurethane is substantial importance in modern seal technology.

Our polyurethane materials range from shore A hardness 57 to 95 and are all Hydrolysis resistant – often referred to as H-PU. With a huge range of material stocks, there is no such thing as a special requiring an extended lead time.

Besides standard PU materials, we also offer materials with an optimized coefficient of friction and for direct contact with foodstuffs. We offer a range of material colours to suit all applications.

Custom Seals

When you’ve tried standard profile seals without success or know you’re going to need a bespoke solution for a particular project, we can deliver what you need.

POLYURETHANE DATASHEETS
AF1008a Data Sheet U580-D57G Polyurethane U580-D57G + MoS2 – Grey

U580-D57G is a MoS2 filled hydrolysis-resistant (H-PU) cased Polyurethane based on MDI polycarbonate polyol and certain additives. The hardness is adjusted at 7 Shore D which results in excellent extrusion resistance. Used as a dynamic sealing element in composite seals, easier installing and better sealing performance in combination with less friction and reduced stick-slip effect will be the main advantage of this material.

U530-B95-LT is a hydrolysis resistant polyurethane (H-PU) based on polyether-diol and methylene diphenyl diisocyanat (MDI). The hardness is adjusted at 95 +/-2 Shore A. The product is recommended for applications at low temperatures (-50°C), but also in standard hydraulic applications (≤105°C) as well as hot water applications (≤90°C).

AF1010 Data Sheet U510-G88 Polyurethane U510-G88 – Light Green

U510-G88 is a hydrolysis-resistance (H-PU) casted polyurethane based on MDI, polycarbonate polyol and certain additives. Due to the adjustment at 90 Shore A it is very flexible and easier to install in tight housing situations and is also used when a ‘softer’ material is needed to have higher compression (preload) of the sealing material.

AF1012 Data Sheet U540-V195-CR Polyurethane U540-V195-CR – Violet

U540-V195-CR is a hydrolysis-resistance (H-PU) casted polyurethane based on MDI, polycarbonate polyol and certain additives. It is resistant against the common used CIP-fluids and shows low swelling effects in non-polar fluids like mineral oils or fatty foodstuff.

AF1009 Data Sheet U500-R95 Polyurethane U500-R95 – Red

U500-R95 is a cast polycarbonate based, hydrolysis-resistant polyurethane. Its excellent physical properties such as high abrasion resistance, high extrusion resistance as well as its flexibility make it a universal material for seal applications.

AF1007a Data Sheet U570-D57 Polyurethane U570-D57 – Dark Blue (FDA)

U570-D57 is a hydrolysis resistant PU (H-PU) casted ployurethane, based on MDI, polycarbonate polycol and certain additives. The hardness is adjusted at 57 Shore D which results in excellent extrusion resistance. Used as a dynamic sealing element in composite seals, easier installing and better sealing performance will be the main advantage of this material.

AF1005a Data Sheet U550-GM95 Polyurethane U550-GM95 – Dark Red

U550-GM95 is a MoS2 filled hydrolysis resistant PU (H-PU) casted polyurethane based on MDI polycarbonate polyol and certain additives. It is recommended in application where reduced friction and poor lubrication is an issued. The material is able to reduce or eliminate the stick-slip effect when it appears.
