Discussion Overview

The discussion centers around the search for a high-temperature rubber suitable for use as a lamination press pad, specifically targeting materials that can withstand temperatures around 700°F (370°C). Participants explore potential materials and suppliers, as well as the challenges faced with current options.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about high-temperature rubber options for lamination press pads, seeking recommendations for materials and suppliers.
  • Another participant suggests that silicone rubbers may not meet the required temperature range and proposes Teflon as a potential alternative, recommending contacting Garlock for their product offerings.
  • A participant currently using Teflon reports issues with its lack of "spring back" after heat and pressure, leading to voids or bubbles during lamination, and notes the high cost of single-use Teflon.
  • Another reply encourages contacting Garlock again, mentioning the possibility of new high-temperature materials with better elasticity than Teflon.
  • A participant confirms they have reached out to Garlock and will share any findings.

Areas of Agreement / Disagreement

Participants express differing views on the suitability of Teflon for the application, with some suggesting alternatives while others acknowledge the limitations of current materials. The discussion remains unresolved regarding the best material choice.

Contextual Notes

Limitations include the uncertainty about the performance characteristics of suggested materials and the lack of detailed specifications for high-temperature rubbers. The discussion does not resolve the effectiveness of Teflon versus other materials.

Who May Find This Useful

Individuals involved in industrial lamination processes, materials science, or those seeking high-temperature materials for specialized applications may find this discussion relevant.

Can somebody help me out? I a looking for a high temp rubber to use as a lamination press pad. Hopefully something over or around the 700 F (370 C) range. If you know of a material great... if you know of a supplier awesome.

Thanks!

I think you are asking for something out of the performance range of even silicone rubbers. You might need to get into Teflon to get that kind of performance. You can contact Garlock (http://www.garlock.com/) to see if they have a supply-company carrying their product line in your area. They probably have sheets of Teflon materials (http://www.gore.com/en_xx/) on hand to cut custom gaskets for industrial customers.

Thanks for the response! I am currently using Teflon which works for the most part. A couple of the problems I am seeing are:

1. After heat and pressure are applied there is no "spring back" of the teflon so I sometimes deal with voids or bubbles during lamination.

2. Teflon is only one time use. It is costly to only use once.

Thanks -
 
OK, still you should contact Garlock. I have been out of that business for many years, and they may have some new high-temperature materials with better elasticity than Teflon. Good luck.
 
Thanks a lot! I just contacted them. I will let you know what I find out.
