Bis(1,2,2,6,6-pentylmethyl-4-piperidinyl) sebacate: A Promising Light Stabilizer for Polymers
Bis(1,2,2,6,6-pentylmethyl-4-piperidinyl) sebacate (BP-4) is a highly effective light stabilizer for polymers, particularly in outdoor applications. It belongs to the class of hindered amine light stabilizers (HALS), which are widely used to protect polymers from degradation caused by UV radiation, heat, and oxidation. BP-4 is a relatively new member of the HALS family, but it has already gained popularity due to its excellent performance, low volatility, and compatibility with various polymer matrices.
INNO Specialty Chemicals is one of the leading manufacturers and suppliers of BP-4 in China. The company has a state-of-the-art production facility and a team of experienced scientists who develop and optimize the synthesis and application of BP-4. INNO Specialty Chemicals offers BP-4 under various trade names, including BASF light stabilizer Tinuvin 292, UV absorber UV-292, Light Stabilizer UV-292, Light Stabilizer 765, and others.
BP-4 has several advantages over other HALS and UV absorbers. Firstly, it has a high degree of solubility in many polymer matrices, including polyolefins, polyamides, polyesters, polycarbonates, and others. This makes it a versatile light stabilizer that can be used in a wide range of applications, such as films, fibers, tapes, molded parts, and coatings. Secondly, it has a low melting point and a low viscosity, which facilitates its incorporation into polymer melts and avoids processing problems, such as plate-out, blooming, or discoloration. Thirdly, it has a long-lasting effect on the polymer properties, as it scavenges free radicals and prevents chain scission, crosslinking, or yellowing caused by UV exposure.
BP-4 is particularly suitable for outdoor applications, where polymers are exposed to harsh conditions, such as sunlight, rain, humidity, and temperature fluctuations. It can effectively protect polymers from photo-oxidation, photo-degradation, and loss of mechanical properties, such as tensile strength, elongation, and impact resistance. BP-4 can also improve the color stability of polymers, as it reduces the formation of chromophores and photo-products that contribute to color fading or discoloration.
BP-4 can be used alone or in combination with other light stabilizers or antioxidants to achieve a synergistic effect. For example, it can be combined with UV absorbers, such as benzotriazoles, benzophenones, or cyanoacrylates, to broaden the spectrum of protection and enhance the efficiency of UV absorption. It can also be combined with hindered phenols, such as Irganox 1010, or phosphites, such as Ultranox 626, to provide complementary protection against thermal and oxidative degradation.
BP-4 has been extensively tested and approved for various applications and standards. It complies with the EU REACH regulation, the US FDA regulations for food contact, and the RoHS directive for electronics. It has also passed the ASTM and ISO tests for weathering, lightfastness, and photostability. BP-4 is a safe and eco-friendly light stabilizer that does not contain heavy metals or harmful substances.
In conclusion, Bis(1,2,2,6,6-pentylmethyl-4-piperidinyl) sebacate is a promising light stabilizer for polymers that offers several advantages over other HALS or UV absorbers. It is a versatile, efficient, and long-lasting additive that can improve the performance and durability of polymers in outdoor applications. INNO Specialty Chemicals is a reliable supplier of BP-4 that provides high-quality products and technical support to its customers.
