RTV Silicone Rubber Rolls IT68S-Matte
The roll is lined with silicone rubber RTV (Room Temperature Vulcanizing).
Allows adjustment of surface roughness depending on your application.
Application
- Sheeting roll
- Embossed roll
- Embossed back roll
Features
■Seamless processing
No processing traces such as seams that occur during general rubber molding.
■Liquid RTV (Room Temperature Vulcanizing) silicone rubber
■Compound design suitable for each application
■Excellent mold releasability and heat resistance
Since the material is silicone rubber, it has excellent mold release effect and heat resistance.
Structure
Base material (metal core)
Intermediate layer : IT68S-H or Synthetic rubber
Outer layer : IT68S-Smooth
Metal core bar can be bonded as is or can be bonded with a synthetic rubber (EPT/NBR) layer.
New surface layer re-installation is available (rewinding).
