Rubber Bonding
Rubber to Metal Bonding
Specialty items for machines, pumps, valves, control instrumentation manufacturers.
Customization is what we do best!
Rubber to Plastic Bonding
Customized molded bonding services for a wide range of dynamic applications.
Roller ski wheel (far left) with bonded plastic hub that undergoes severe shear and compressive stresses during use without failure.
Highly dependable diaphragm (right) with bonded plastic inserts that undergo millions of tensile and compressive stress cycles without failure.
Rubber to Teflon™ Bonding
Tempron shares in the patented process for the manufacture of this Teflon™ lined gauge isolator. The unique feature of this isolator is that the annular space for the gauge fluid is formed in the molding process, when rubber is bonded to the Teflon™ and the isolator body.
Pump Diaphragms
Solenoid Driven Pump Diaphragms
These high quality, Teflon™ faced diaphragms pump millions of strokes without the Teflon™ cracking or delaminating from the fabric reinforced rubber. The example shown combines a special Telflon™ film, Hypalon® rubber, polyester fabric, and glass filled nylon insert to form a multi-component, durable chemical metering pump diaphragm.
Mechanically Driven Pump Diaphragms
This highly reliable diaphragm operates 24/7 at full pressure, with maximum speed and output. It is lab-tested to exceed 200 million cycles – twice the ISO warranty.
Air Operated, Double Diaphragm Pumps
Our integrated, bonded insert design eliminates the problematic leaks around the shaft prevalent in many of the current bolted-on styles. These diaphragms provide a higher level of reliability than PTFE sheets with rubber backing.
Valve Diaphragms
Solenoid Actuated
A PTFE bonded fluorocarbonelastomer diaphragm used to dispense either ultra pure fluid or highly aggressive chemistry.
Applications: valving for diagnostic instrumentation; biomedical, pharmaceuticals, or microchip processing.
Air Operated
PTFE bonded elastomer diaphragms for air operated valves or pressure control.
Applications: Plastic piping systems or chemical processing facilities.
Weir Type or Similar Styles
Bonded PTFE or all-rubber diaphragms for mechanically operated valves.
Applications: On/Off flow control and actuated valve.
Teflon™ Fabrication
TEFLON™ DEFINITION / FLUOROCARBON RESINS
Teflon™ is a DuPont registered trademark for a series of fluoroplastic resins comprising polytetrafluoroethylene. These resins are commonly referred to as PTFE/TFE, mTFE for modified PFTE, PFA or FEP depending upon their chemical makeup.
Tempron’s experience with all of the different resins and their manufacturers allows us to meet your specific requirements and assist you with your designs. We have 25 years of experience in bonding PFTE films to rubber.
We have developed proprietary processes to form thin-walled diaphragms, seals and multi-thickness parts that are difficult to machine or mold.
Seals
Teflon™ Bonded to Rubber
PTFE or MPTFE bonded to rubber for sanitary piping systems.
Application: Pharmaceutical, ultra pure, food processing, aggressive chemical environment, maximum solvent resistance.
Perfluoroelastomer
Tempron has expanded its fluoroelastomer capacity to include perfluoroelastomer (similar to Kalrez®, Chemraz®) parts.
Parts molded of perfluoroelastomer provide maximum chemical and solvent resistance approaching PTFE.
All Rubber – Chemical Resistant
Tempron has 30 years of experience in the molding of Fluoroeslastomers (Viton®, Fluroel™, Aflas®) for seals and diaphragms.
