How does KYDEX® compare to ABS and PC (Polycarbonate)?
Kydex® sheet provides:
- Greater chemical resistance than ABS and PC
- Higher impact resistance than ABS.
- More uniform wall thickness than ABS and PC in deep drawn thermoformed parts, allowing down gauging of thickness in certain applications.
- Lower moisture absorption. Kydex® sheet is less hydroscopic than ABS and PC, reducing or eliminating the need to dry the sheet prior to thermoforming.
What is the Flammability rating of KYDEX®? Does it meet the UL Std. 94 V-O rating?
KYDEX® sheet, depending on the grade used, offers various flammability ratings and is used for applications requiring extremely stringent flammability requirements.
What are the thermoforming temperature ranges for Kydex® sheet?
Please refer to the Kydex® Thermoforming Guide for information on thermoforming temperature ranges, mold characteristics (draft angles, radius, mold shrinkage, etc.) for make and female molds.
