Polyurethane, PUR or PU, as it is also called, is a flexible material with properties that make it convenient to use almost everywhere. Polyurethane provides comfort, safety and design in a variety of products we use in everyday life – without PUR, our lives would look quite different.
At ESMA we mainly work with four different PUR variants; integral hard foam, compact foam, casting system and flexible foam. Which one is best to use in your project? Contact us at ESMA and we will help you with the material that best suits your needs.
PUR Integral Hard Foam (IHS)
Sandwich technology with high rigidity
Flexible design and construction
Good insulation property (heat and noise)
IHS is used in many different areas, such as medical technology, food industry, payment stations and consumer electronics.
PUR Casting system (GS)
The material for high mechanical and chemical requirements
Alternative to grey cast iron or steel
GS is used in the agricultural industry, construction industry and sewage technology.
PUR Compact foam (K 110)
High impact strength and compact structure
Alternative to injection molding
Large format components up to 6m² of projected area
The K 110 is for example used in large enclosures, within medical technology (for X-ray such as MR, CT), for construction and agricultural machinery and in the automotive industry.
PUR Flex foam
High impact strength even at low temperatures
Flex foam is for example used for load machines, driver cabins and industrial trucks and for other products in the construction and agricultural industry.
PUR has low weight, very good durability and high elasticity. It is form-stable, chemical resistant and has good oil resistance. PUR also withstands both low and high temperatures and is weatherproof (wind and UV radiation). It is non-static and has a good insulation and silencing ability.
PUR is a two-component product consisting of polyol and isocyanate in liquid form. When these two are mixed, a reaction occurs and polyurethane is the result. Depending on how you mix the material – and what manufacturing technique you use – the properties can be customized according to the desired use.
