SIMONA® Versarod® is a proprietary weld rod that allows seamless fabrication in wet/dry process tool construction. Versarod® allows exhaust plenums to be thermoplastically sealed, welding SIMONA® PVDF to SIMONA® PVDF on the inside of the tool, and SIMONA® PVDF to SIMONA® CRP 1 on the outside of the pipe to cabinet weld. Versarod® also allows PVDF plumbing pass-through to be thermoplastically sealed, removing the need for secondary braces and securements. 

Advantages

• Welds SIMONA® CRP-1 FM 4910 to SIMONA® PVDF or SIMONA® PVDF-C
• Good weld strength and weld ductility
• Continuous use temperature nominal 60 to 65 °C
• Allows seamless tool construction and weld sealed SIMONA PVDF plumbing through SIMONA CRP-1 cabinet walls
• Proven, historical performance with tools still in service since 1999

Applications

• PVDF fittings and plumbing
• Plenums and pump box walls
• Wet and dry process tool fabrication
• Cabinets, casework, tables

Rod Configurations 

• 4.0 mm (0.156 in) diameter, clear
• 4.0 mm (0.156 in) diameter, white

Hot Gas Weld Parameters

• Temp: 380 °C
• Flow: 60-65 LPM
• Speed: 0.25-0.50 in/sec
• Pressure: sufficient pressure should be applied to the tip to produce weld rod ‘wake’
• Melt viscosity is relatively low. Versarod will appear soft/limp immediately after welding
• Versarod will begin to ‘set’ after 2-3 minutes, reaching full strength after 10 minutes
• Priming the weld seam is important to achieve maximum adhesion

SIMONA AMERICA Industries manufactures the widest range of FM 4910 sheet, rod, and welding rod in the industry, featuring SIMONA® CRP-1 material as the leading material for critical applications. All of our compliant materials are designed to satisfy semiconductor process applications without compromise.

CRP-1 to PVDF chemical compatibility and service temperature.

Versarod Maximum Continuous Service Temperature

Versarod® weld rod is serviceable at 65°C, but may have higher use temperature. Depending on configuration, Versarod is limited to 72 to 75 °C use temperature of CRP-1.

Notes:

• Direct continuous contact with the above chemicals was assessed at ambient temperature
• Direct continuous contact was not tested at elevated temperatures or at the maximum recommended use temperature. The above service temperatures are based upon knowledge of historical applications.
• Because end use varies, SIMONA AMERICA Industries recommends verification and suitability of individual applications.
