Polyurethane is a polymer formed by a reaction of polyisocyanate with a polyol. Depending on the proportions used and the use of additives it has a wide range of properties. One type of material that can be obtained is integral polyurethane.

Integral polyurethane consists of a flexilble, light and porous core and and outer, tougher, denser layer with characteristics of a closedskin structure.

• The inner polyurethane foam provides softness and elascitity.

• The outer “skin” layer is resistant to attrition and deformation. Even upon long term pressure, the product retains its original shape (shape memory).

Integral polyurethane can be used in multiple projects and products can vary in shape, colour, pattern and hardness. To obtain the required shape, we use special moulds made of aluminium, steel or epoxy resin. By reinforcing inner elemenets and adding specific components to the polyurethane mix, the manufacturing possibilities are increased.

Polyurethane may be of any hardness, depending on the application and product requirements. Polyurethane hardness is determined with a Shore durometer.

Each product is moulded. Aluminium, epoxy resin, or steel moulds are used.

Overall of the properties of integral polyurethane:

• Resistance to attrition, deformation and UV rays gives the product hardware properties.

• Resistance to various chemicals helps to keep it clean.

• Resistance to humidity allows to keep the products in a hygenic conditions and reduces the risk of bacterial and fungal growth

• Elasticity influences the ergonomics and comfort of use of the product.

• The material posseses hypoallergenic properties.

• Products do not require upholstering and yet are more durable than leather or plastic coatings which although made carefully, do not provide the effect of an integral element.

Due to its characteristics, polyurethane is used for products in which people have direct contact with the object. It is ideal for use in the scope of safety, comfort, insulation and ergonomics making.
