BASF light stabilizers protect oil spill barriers from degradation by intense sunlight
- Additives package provides long-lasting protection to oil spill barriers against harsh weather conditions
- Longer durability reduces environmental impact and saves costs
Hong Kong – May 28, 2019 – Marine oil spill barriers, also known as oil containment booms, can last longer and keep oil spills under control even under intense sunlight, thanks to light stabilizers from BASF. Wonpoong Corporation in South Korea is now using BASF’s Tinuvin® range of plastic additives to increase the lifespan of oil containment booms, thereby reducing the maintenance costs and environmental impact.
A containment boom is a heavy-duty debris and oil spill containment barrier, designed for a long service life with minimal maintenance. Made with marine grade components and oil-rated fabrics, these barriers can float in the water and contain oil while spill recovery is underway. This reduces the possibility of polluting shorelines and other resources, and to help make recovery easier.
The barrier fabric is usually made of woven polyester that is impregnated with polyurethane for better resistance to both abrasion and tear. The fabric is orange in color, and requires protection from prolonged UV and hydrocarbon exposure which shortens the fabric life.
“Light stabilizers reduce and significantly delay the loss of optical and mechanical properties of plastic articles used in outdoor applications,” said Hermann Althoff, Senior Vice President, of BASF’s Performance Chemicals unit in Asia Pacific, BASF. “Our light stabilizers can increase the service life of the product several times, and simultaneously reduce the resource consumption caused by the aging of the product.”
Wonpoong chose a blend of PVC (polyvinyl chloride) and TPU (thermoplastic polyurethane) to manufacture the foam-filled oil containment booms. However, they do have some disadvantages. While TPU has better wear strength and softness compared to PVC, due to its poor resistance to light, TPU is easily discolored.
“We needed to strengthen the chemical resistance of PVC while enhancing the light resistance of TPU,” said John Yu, Director of R&D at Wonpoong Corporation. “As a result, we required a light stabilizer with improved resistance to UV radiation that could preserve the original appearance and physical properties of the material.”
The choice was a light stabilizer package from BASF’s Tinuvin® range, that is ideal for PVC alloys like PVC/PUR. This high performance light stabilizer system is based on compounds of the sterically hindered amine light stabilizers (HALS). The hindered amines act in a similar manner to how vitamin C protects the human body; they intercept radicals and make them harmless. The duration of this protective effect can be controlled by selecting a specific stabilizer additive.
