Bonding Polyphenylene Sulfide (Ryton*) Polyphenylene sulfide (PPS) offers thermal stability and good mechanical properties. It is resistant to acids, alkalies, bleaches, sunlight and abrasion. Dimensionally stable PPS is a superior electrical insulator and is non-flammable. It is used frequently by manufacturers of automotive, healthcare, electronic, electrical and appliance products. Specific applications include:
- Hydraulic components
- Filter housings
- Fuel injectors
- Hair dryers
- Rod guides
Master Bond offers compounds for bonding PPS to PPS and PPS to dissimilar substrates. These systems are epoxy and UV curable adhesives.
Consideration for Bonding PPS - Thermal Stability
Most desirable adhesives for bonding PPS are EP17HT, EP41S-1HT, EP62-1 and Supreme 10HT. It is highly recommended that chemical etching be done prior to bonding. Serviceable up to 650°F, one component, no mix epoxy adhesive EP17HT features high tensile and compressive strength. It has a Tg >220°C. Room temperature curing EP41S-1HT has a moderate viscosity, resists up to 400°F and withstands exposure to solvents, alcohols and fuels. Master Bond EP62-1 features superior dimensional stability, cures at moderately elevated temperatures and exhibits superior electrical insulation properties. Popular Supreme 10HT requires no mixing and resists vibration, impact and shock. This toughened compound is NASA low outgassing approved.
