POSA Elastomeric Gaskets: Advanced Solutions for the Food and HORECA Industry

POSA is a leader in the design and production of high-quality elastomeric gaskets, specifically engineered to meet the most stringent demands of the food industry and HORECA sector. With deep technical expertise and an innovation-driven approach, we offer reliable, safe, and compliant sealing solutions that adhere to the most rigorous international standards.

High Performance in Even the Most Extreme Conditions

Our food-grade gaskets are developed to excel even in the most critical environments. They guarantee resistance to high temperatures, steam, intensive washing cycles, and the aggressive chemicals used for sanitation. Every component is designed to optimize the energy efficiency of machinery and ensure total organoleptic neutrality: our gaskets do not alter the taste or smell of the food they come into contact with.

Available in a wide range of profiles and formats – including complex and multi-component designs – our custom gaskets offer maximum design flexibility and are fully customizable.

Tailored Materials for Every Specific Need

We offer a selection of advanced elastomeric materials, formulated for superior performance in the food sector:

Silicone (VMQ)

Thermal resistance up to 300 °C (572 °F)
Excellent flexibility and elastic memory
Odorless and tasteless: ideal for sealing oven doors and hot chambers
Available in various colors and hardnesses, including co-extrusion
Conductive versions for specific applications

EPDM

Excellent performance up to 150 °C (302 °F)
Exceptional resistance to ozone and atmospheric agents
Preferred for areas not directly exposed to high temperatures

FKM (Viton®)

Exceptional resistance to chemicals and heat
Ideal for critical sealing zones
Greater rigidity and cost compared to silicone

The Advantages of POSA Gaskets: Certified Compliance and Customization

Choosing POSA gaskets means relying on:

Reliable sealing even at high temperatures and under thermal stress.
Certified compliance: FDA, EU 1935/2004, NSF, 3-A, GB 4806.
High customization: tailored geometries, hardnesses, materials, and colors.
Long lifespan and reduced maintenance needs.
Resistance to steam and aggressive detergents.
Perfect integration into professional ovens and automated food processing systems.

Versatile Applications in HORECA and Beyond

Our gaskets for professional ovens are used in baking, rotisserie, and pastry-making, as well as in coffee machines, vending equipment, professional dishwashers, and heated trolleys. Our ability to develop custom profiles makes us the ideal partner for equipment manufacturers and specialized OEMs.

Solutions for Food Processing Plants

Our extruded and molded articles are essential in bottling lines, packaging, drying, refrigeration, and food processing operations. From cold rooms to milk processing plants, we offer robust, certified, and tailor-made solutions for every production environment.

Innovation, Co-design, and Sustainability

POSA leads the way in developing complex products through co-extrusion and co-molding of different materials and colors. Our in-house laboratory formulates dedicated compounds to meet specific functional and aesthetic requirements. Design is carried out using advanced FEM simulation tools, in close synergy with our OEM clients.

Sustainability and Future

We constantly invest in low-impact materials and intelligent sealing technologies. Our long-lasting compounds reduce waste and improve the operational efficiency of the systems in which they are used, offering sustainable performance with a focus on the circular economy.
