EXSTO Italia offers a variety of formulations polyester and polyether-based in different colours and hardness between 30 and 98 Sh°A. Thanks to our cutting-edge machineries, we can manufacture a wide range of products for multiple sectors: from mining to paper, from mechanical to naval applications, from heavy-duty transports to industrial production.
Polyurethane is an eclectic material that combines outstanding features such as elasticity, resistance to a wide range of temperature (up to 90°C), tear and abrasion resistance, high breaking point and mechanical performance, resistance to corrosive chemical agents and hydrolisis, minimal heat accumulation during friction, and much more.
For special applications, which require a superior level of mechanical properties, EXSTO recommends considering Vulkollan® Bayer, an elastomer polyurethane suitable for conditions of very heavy use.
Polyurethane can be vulcanised on many metals and also plastics for the realization of rollers, wheels or any other article also complex due to its ease of molding. With high hardness you can also work with machine tools as any other plastic material. Our company is able to provide a wide range of semi-finished products such as rods, sleeves, plates and blocks also of considerable thickness. Its exceptional features, the range of hardness available, ease of molding and its general versatility, allow this material to solve a wide range of problems in all industrial sectors.
The polyurethanes, whose discovery dates back to 1937 thanks to the research of the German chemist prof. Otto Bayer, belong to the the plastics family. Are obtained by reaction between an isocyanate and a polyol, which produces a physical change of state from liquid to a solid and elastic material. Changing the raw materials and the combinations between them, with appropriate ratios, it is possible to obtain diversified properties that qualify for the different applications. Taking into account how many isocyanates and polyols are now available, additives, fillers, plasticizers, etc. possible formulations are virtually limitless and give a great variety of properties to polyurethanes. Some are primarily resistant to abrasion, resistant to acids as well as other some have good resistance to hydrolysis. There are polyurethanes with high resilience, in others, however, is practically nil. These elastomers are very resistant to hydrocarbons and oils (both vegetable and mineral). The indisputable resistance to compression of the polyurethane is, combined with its shape memory, a suggestion for countless applications. Research and experience allow you to have the optimal formulation for each application.
The advantage of this product is characterized by the ability to lend itself to different types of machining operations and can be cut, sawn, glued, die-cut or worked to the lathe.

EXSTO Italia can be your best partner for the supply of rollers coated in polyurethane or in rubber.
We manufacture snow plow blades with the correct holes for the most popular brands of snow ploughs such as Giletta/Bucher, Assaloni, Bombelli, Snow Service and others…
Polyurethane bars and sleeves can be employed as motor-driven rollers, idlers, pipes and for other uses. Moreover, by cutting or machining on turning lathe our polyurethane or Vulkollan® bars and rods, we can obtain channel guides, shock aborbers, springs, etc…
We produce small polyurethane plates in sizes 490 x 490 mm and 500 x 500 mm, in thicknesses from 5 to 60 mm; as well as larger polyurethane sheets 2030 x 510 mm in thicknesses from 1 to 12 mm made by centrifugal casting.
Polyurethane springs are elastic elements for tools and moulds: here our selection of Jumpy springs.
EXSTO Italia is specialised in producing modular panels, vibrating and circular polyurethane screener panels in both self-supporting and tensioned versions, through the company’s ultra-modern manufacturing facility.
The abrasion resistance, the decrease of noise emissions, the weight decrease and easy assembly compared to traditional metal systems allow polyurethane panels an increasingly wide consumption inside the screeners.
The company makes modular panels, dryer screens with injection-moulded insert (0.3 x 11.5 aperture) and dewatering drum sections, and an extensive range of specialist screeners. Polyurethane products can be made according to drawing specifications or from a sample, to match retainer holes and reinforcements.
EXSTO Italia produces: discs for star screens, rubber coated metal sheets, impact bars, scapers for conveyor belts, track shoe pads, hydrocylones and much more for the mining and mineral screening industry.
EXSTO produces custom-made parts in polyurethane for a wide range of industries, also including metal inserts or metal hubs.
Do you want to increase your productivity by reducing your control and maintenance operations ?
We have a solution for you: EXSTO is innovating by creating a panel with an integrated wear indicator!
The T-THANE® product range has exceptional abrasion and tear resistance characteristics that greatly outperform all products available on the market.
