RARE EARTH MAGNETS QUICK SHIP AND CUSTOM SIZESRochester Magnet can assist you in selecting the best magnet for your application. Rare Earth Magnets and Neodymium Magnets (Neo Magnets) in particular, are available in a large selection of Discs, Blocks and Rings. However, if you need a special size andor shape, Rochester Magnet can source produce this for you in weeks, not months. Whether you can use a standard design or need a completely custom magnet shape andor size, Rochester Magnet is your technical resource and one stop shop for Neos. Our inventory and relationships with manufacturing companies enables us to provide you with timely, cost effective and positive results. Visit our Quick Ship online store to browse sizes and shapes you can purchase online - see button on right. NEODYMIUM MAGNETSNeodymium2Rare earth magnets are high performance solutions that combine high pull force strength into a small form factor. A Neodymium Magnet (neo magnet) allows the use of a smaller magnet to generate a greater force than a larger magnet made of a different material would. This is particularly useful when strong force is required andor when space is an important design consideration. Standard Grade (N35) Neodymium has very high resistance to demagnetization at ambient temperatures. If your application requires exposure to heat > 176 F, slight demagnetization may occur and high temperature grades may be necessary. Please call us to specify alternate grades and specifications appropriate for your application. Neodymium Magnets are available in a wide variety of sizes, shapes and energy levels. Rochester Magnet offers a number of stock sizes through our Quick Ship inventory. As always, we can also customize most anything you require. MORE INFORMATION ON SIZES AND GRADES>> COMMON APPLICATIONSearth2Packaging Solutions Brochure Neodymium Magnets are commonly found in Packaging Applications where an elegant solution is required for closure. Neodymium discs are sometimes applied exposed, using our convenient pre-applied adhesive. While other applications may require a stealth look, and bury the Neodymium disc underneath the surface. Due to the great strength of these magnets, they allow for the proper reach required to create a secure closure.

Samarium Cobalt provides another Rare Earth Class magnet with properties similar to Neodymium. Although the force potential of these magnets is less, they are significantly more resistant to elevated temperatures. The higher cost and lower energy potential of these magnets typically makes them best suited for applications with a high force requirement within a high temperature environment. Since these magnets are not subject to corrosion, they are typically uncoatedunplated. However, they are also very brittle and must be handled carefully or they will chip. Additionally, care must be taken in the application to minimize shock or fracture or else chipping can occur. Standard SmCo sizes and grades are provided in the link below.

Rubber adhesives are made from natural or synthetic rubbers and are formulated with various compounds to become tacky. High initial strengthVery good general purpose usesMost cost-effective PSAAdequate for short-term, non-critical, indoor applicationsLimited chemical, temperature and UV light resistanceNot recommended for high heat applications

Acrylic adhesive tapes are a combination of acrylic monomers and other compounds formulated to create specific chemical structures that are tacky. Widest range of performance characteristicsAdheres to most surfaces permanentlyGood initial strength that builds with dwell timeTypically develops stronger bond than rubber-based adhesivesLong-term aging, outdoor stabilityOutstanding chemical, temperature and UV light resistance

A closed cell, cross-linked polyethylene foam coated on both sides with either acrylic or rubber based adhesive. Foam adhesives offer strong bond for uneven surfaces. This series is supplied in thicknesses from 132" up to 18" thick. FEATURES & BENEFITS High shearBond well to irregular surfacesExcellent UV and temperature performance

A fairly thin, flexible carrier adhesive material that is coated on both sides with a pressure sensitive adhesiveUsed to bond two substrates, either similar or dissimilar in nature, togetherHighly customizable with the two adhesive layers being the same or different adhesivesProtected by a release liner on one side with the other side exposedIdeal for gasket bonding, insulation materials, bonding electronic components, attaching molding, extruded plastic parts and more

A flexible carrier adhesive tape material that is coated on one side with a pressure sensitive adhesiveUsed to bond the product to a substrate - splice other items togetherCan be protected by a release liner which is removed and discarded at the time of installation

Also called free film, this product consists of a layer of pressure sensitive adhesive without a carrierProtected by a release liner on one side with the other side exposedMore extensible and conformable because there is no carrierIdeal for mounting nameplates, second surface printed signs or labels, and other decorative substrates
