The 8 family members and key features of Vulkollan®
Hardness
Formulations from soft to very hard makes Vulkollan® spanning the full spectrum between rubbers and thermoplastics. Thanks to this wide range of hardness, Vulkollan® can be found in a broad area of technical applications. Vulkoprin produces Vulkollan® ranging from 75 up to 97 shore A
Tensile strength
Vulkollan has very high values for tensile strenght. Elongations up to 7 times the original length is needed before rupture of the specimen occurs. Together with high values for tear and tear propagation means Vulkollan® is virtually unequalled for wear and tear in conditions of dry or wet friction
Damping
Good damping behavior, combined with the other physical properties, makes Vulkollan® the ideal material for anti-vibration elements
Rebound resilience
The rebound resilience gives a measure for the elasticity of a material. Vulkollan® shows high and almost constant values over the whole hardness range between 0°C and 120°C. The higher the rebound resilience the less energy is transformed into heat by a deformation
Chemical resistance
Unlike many other elastomers, Vulkollan® is highly resistant to many chemicals and, in particular, to mineral oils, petrol and benzene
Compression set
Compression set is the amount by wich a compressed elastomeric material fails to return to its original shape when the load is removed. The low compression set of Vulkollan® is a decisive factor behind its successful use for items such as wheels, damping and sealing elements
Tear strength and tear propagation resistance
Vulkollan® has high values for tear strength and tear propagation resistance. This, together with the high elasticity, offers exceptional wear resistance in dry and wet conditions.
Wear
Vulkollan®’s high resistance to wear ensures a long service life for expensive capital investments even under the harshest abrasive loads

In the food industry, operational performance is built on the precision and quality of every single component. For companies operating in environments governed by strict regulations, the careful selection of materials and the technical specifications of castors and mobile supports are essential to ensure maximum resistance, hygiene, safety, and durability.
Material handling systems must not only be capable of managing significant loads under demanding working conditions, but also meet rigorous sanitation and durability standards, minimizing the risk of contamination and ensuring consistent, long-term performance.
With more than eighty years of experience across four generations, AVO has a deep understanding of the sector’s requirements and has developed a product range entirely dedicated to overcoming these challenges.
AVO solutions are engineered to maintain superior performance even at high temperatures, a common factor in environments such as industrial kitchens, pasteurization plants, and ovens. Our range includes castors made from compounds that offer excellent resistance to chemical agents and thermal shock, featuring smooth surfaces free from gaps or joints that could compromise hygiene.
The supports are also designed to deliver maximum structural reliability, reducing wear and the risk of premature failure, even under the most demanding operating conditions.
A distinctive element of our portfolio is our range of high-temperature castors. These are advanced technical solutions, indispensable for production environments exposed to prolonged heat or intensive thermal cycles.
The range includes castors made from thermosetting phenolic resin, versions with rubber tread and glass-fibre-reinforced Polyamide 6 cores, as well as silicone rubber models with aluminium cores or steel flanges. These configurations ensure safe and reliable operation for applications reaching temperatures of up to +280°C.
The thermosetting materials used, such as phenolic, urea, and melamine resins, are ideally suited to severe thermal conditions. Unlike thermoplastic compounds, their rigidity increases with heat, preventing permanent deformation and ensuring long-term dimensional and mechanical stability.
AVO castors are available in diameters ranging from 80 to 250 mm and can be combined with medium-duty or heavy-duty supports. This modularity allows load capacities from 80 to 800 kg, depending on the selected configuration.
With AVO, food industry professionals can rely on components that enhance the efficiency and quality of their production processes, without ever compromising on final product safety.
AVO presents the new Heavy-Duty Stainless-Steel Castors: maximum corrosion resistance for critical environments
Avo expands its product portfolio with a new line of heavy-duty stainless-steel castors, engineered to deliver reliable and safe performance even under the most demanding operating conditions.
The range is designed for high-intensity food, pharmaceutical, and industrial applications where high load capacities are required.
Manufactured entirely from AISI 304 stainless steel, this series offers superior resistance to corrosion, aggressive cleaning agents, and high-pressure washdowns. This makes it ideal for the food industry, the pharmaceutical sector, refrigerated-logistics environments, and all applications exposed to strong mechanical and chemical stress.
