Western Rubbers India Pvt. Ltd. is a pioneer in bringing the technology of manufacturing custom moulded fabric reinforced inflatable seals in India.We take pride in being one of the biggest manufacturer of fabric reinforced inflatable seal.

Fabric reinforced inflatable seals are used when we need to seal two surfaces which can move in with reference to each other. The elastic properties of rubber which allow a seal to be dynamic, by letting it inflate and retain the original position on deflation, is what makes inflatable seals so special and widely used in the engineering fields for sealing.

• Usable in continuous operations at closed pressures of upto 20 bar(kg/mm2).
• Different types of fabric can be used to enhance working pressure
• On deflation, the seal retains original shape
• Fabric reinforced seal give longer operational life as compared to normal seals in higher pressures.
• They do not suffer from premature loss of compression set

The inflatable door seal is used in advanced applications where perfect sealing of door is required. In industries like pharmaceutical, chemical processing, nuclear power and other such industries sealing is critical. To prevent contaminants from entering a particular room, engineered rubber products like inflatable seals find its applications.For high-pressure sealing, reinforced inflatable rubber seals are used. These inflatable seals are inflated upon door closure to seal the gap between thedoor and its surrounding frame. The property of rubber is such that is expands to completely cut off and isolate the entire room. Hence these molded rubber seals are best suited for such advanced applications.

• Silicone rubber for FDA compliance
• FKM rubber for high temperature application
• Natural rubber for good elongation and acid resistance
• EPDM rubber for excellent water and UV resistance
• Buna N/Nitrile rubber has good oil resistance
• Chloroprene rubber suitable for marine applications

Silicone rubber since its discovery has been used for a wide range of applications.One such sector in which it has been extensively used is in manufacture of inflatable seal for Pharmaceuticals. Because of itschemical inertness, Food grade properties and its transparency, It became on of the favorite choices in selection of polymeric raw materials.Some of the main unit processes in the production cycle of any pharmaceutical industry include granulation, blending, Drying, coating etc.

In the process of Drying these companies use machines called asFluidized Bed Dryers(Also known as Fluidized Bed Equipment acronym: FBE) or more commonly known asFBDs.Coating processes make use of the Machines called Coaters.

These machines have chambers, which have to be cleaned to start another batch, change filter bag or sometimes just for maintenance shut down. Hence these machines are never in one piece but generally have openings. The thing about these openings is that even when they are in operation they create contamination by bringing in the outside atmospheric air.One thing common about all of these machines is that they need to be 100% contamination free. That implies, no atmospheric substance including air can come in contact with the product being processed.

Silicone inflatable seal was developed to solve this sealing problem.

Silicone inflatable seal because of their unique FDA properties that made them different than regular seals. These seals can inflate and seal all nooks and corners perfectly. Therefore this provides 100 percent sealing.Platinum Cured Transparent silicone inflatable sealsare manufactured for use in fluid bed dryer ( FBD, FBP, FBE) machines of capacities from25 kg to 1500 kg.Hence we have inflatable seals for ACG, Tapasya, Anish Pharma, Ganson, Alliance engineering, Glatt, Bectochem machines are available ex stock.

In our todays world robotic arms or robots have become a very common thing to see from Mega factories to houses. In Mega factories machines like robotic arms have been working with accuracy and speed for many tasks that humans couldnt do it with speed or with high precision tirelessly. Western Rubbers India Pvt. Ltd. has developed robotic clamp inflatable seal for robotic automation industry.

One of the job of robotic arms in these factories is to lift an article from a place and to keep to another. There are various mechanisms to do this. But to move fragile and delicate items from one spot to another, a robotic arm gripper with inflatable seal mechanism is used.

Robotics arms have clamps fitted inside with an inflatable seal. When it wants to lift an article, The clamp moves over or around the article, the inflatable seal is pressured with air or hydraulic oil so as to inflate it. Due to inflated position it holds the article tightly. Once the robotic arm has a firm grip on the article it lifts and places it on the desired location. Once the robotic arm places the article on the desired location. After which it returns to its original position. This continues in an automated loop, thereby speeding up themanufacturing process.

Brief:-

Because of their high chemical resistance and outstanding sealing properties, PTFE-enveloped gaskets have been proven excellent when used at fluctuating pressures and temperatures. Also the are non adhesive and protect the insert against any chemicals due to the chemical resistant nature of PTFE.

Advantages:-

• High chemical resistance
• Anti Adhesive
• High temperature range
• Can be used in food and pharmaceutical applications

When the gap to be sealed between to rectangular surfaces having sharp corners or to seal two surfaces with irregular profile, in these cases customized moulded seals are used instead of the conventional extruded compression seals. The advantage of custom moulded seals is that dimension accuracy is well maintained specially around sharp corners or joints . Moulded seals shape does not deform at any spot in the seal. If its required to have a razor sharp fitting in an assembly that where moulded door seals are used.

Elastomers used for manufacturing Moulded door seals:-

• Silicone rubber has chemical resistance , FDA complianceand excellent elongation properties
• FKM has excellent chemical resistance andhigh temperature resistance
• Natural Rubber is seldom used because of itspoor aging propertiesexcept in cases where abrasion resistance is required.
• Buna N / Ntrile has good physical properties and excellentresistance to petroleum based fluids
• EPDM has very good weather resistance as well assteam resistance
• Chloroprene has good weather resistance andflame retarding properties

We can manufacture Moulded door seals in from5 Shore A hardness to 90 Shore A hardness

Application

• Class 1000 , 10000 units in Pharmaceutical clean room in Sliding doors
• To enclose equipment for sealing in large Vessels.
• High temperature seals and steam resistant seal for autoclave gaskets
• Large Furnaces to enclose the furnace chamber
• Used as Gaskets in Fabrication and engineering industries
• Train coaches and compartment sealing.
• Window seals for noise reduction
• Used in Jam rooms and musical concert halls for sealing to improving acoustics
