• Consult with us about the inner diameter, film thickness, and shrinkage rate, as the dimensions that can be casted will vary depending on the balance of the three.
• TST can provide shrinkage force such that heating at 150 to 200˚C results in 8 to 15% of shrinkage.
• The inner surface can be etched to support adhesive processing.
• It is also possible to add coloring and conductivity.
