Radiation Processing Program at the Malaysian Nuclear Agency

摘要

Radiation processing technology has been proven to enhance industrial efficiency and productivity, improve product quality and competitiveness. For many years, varieties of radiation crosslinkable materials based on synthetic polymers have been studied at the Malaysian Nuclear Agency either in the form of thermoplastic resins, polymer blends or composites. At present, effort is focused towards developing new materials based on natural polymers such as natural rubber and rubber based products, palm oil and palm oil based products and polysaccharide. Hydrogel based on sago starch has been developed and commercialized for face mask. As for wound dressing application, sago hydrogel is still subjected to the clinical evaluation. Sago starch has also been modified for biodegradable products such as bio-film and bio-foam for packaging purposes. On the other hand palm oil based acrylate resins have been synthesized at the Nuclear Malaysia for pressure sensitive adhesive and printing ink applications. Meanwhile, natural rubber is used in a polymer blend and composites for automotive components. All of these products are at various stages of commercialization.
