Peroxide Factice – Sulphur-free and Chlorine-free

Using modified castor oil, crosslinked with peroxide, leads to a white, sulphur-free, and chlorine-free factice. This product is excellent for application in higher vulcanization temperatures – like LCM and microwave curing. Factice WP demonstrates improved compression sets in comparison to the sulphur factices.
