Chiguard® R-455

UV absorber (UVA) is the most important product series of Chitec. With the comprehensive product portfolio, Chitec’s UVA line plays an important role in the worldwide UVA market.

UV absorber 
UV absorbers are a group of compounds capable of absorbing ultraviolet rays efficiently and dissipating them into harmless heat. Upon long-term exposure to sun light, plastic and coating materials incur degradation as a result of photo-oxidation triggered by the UV light in the sun light which in the long run causes deterioration of the appearance and failure of mechanical properties. Adding proper amount of UV absorbers (normally 0.2%-0.5%) into the plastic or coating material can block out harmful UV rays and thereby delay the aging of products, a truly realization of green chemistry. UV absorbers supplied by Chitec can be further categorized into the following lines based on functional groups, i.e. benzotriazole based UVA, benzophenone based UVA, triazine based UVA, formulated UVA and others. Each product line has its own advantages and applications.

Chiguard® R-455 belongs to the benzotriazole based UV absorber family which is the first line of additive to combat with UV light in coatings, sealants and plastics. Chigurad® R-455 has a proprietary primary diol structure which makes it act like polyol and hence is reactive to isocyanates. Once reacted with isocyanates, it becomes the backbone of polyurethane chain which completely solve the migration or blooming issue of UV absorbers observed frequently in PU based applications.
Chiguard® R-455 can be used in aliphatic and aromatic PU system and can be used for TPU and PU coatings. It is also ideal for siloxane and fluoro polymeric system as well which migration and blooming issue of additives.

Revonox® 608

Heating, compounding, extrusion and other common processes occur during the manufacturing of plastic articles. These processes may degrade and oxidize the plastic and therefore result in material deterioration. The function of antioxidants is to mitigate this kind of deterioration for protecting the mechanical properties of the plastic.

The antioxidant launched by Chitec prior to 2010 was called Deox®, and that launched after 2010 was called Revonox®. There are many types of plastics available on the market, each having an applicable antioxidant. Chitec’s antioxidants can be categorized into the following lines:
[Primary antioxidants] 
Hindered phenolic antioxidants, metal deactivators, benzofuranone antioxidants and hydroxylamine antioxidants.

[Secondary antioxidants]
Phosphorous based antioxidants and sulfur based antioxidants.

  Spiro phosphates are known for their high antioxidization efficiency. In addition, they are the only phosphite antioxidants that can reverse the oxidized form of the hindered phenolic antioxidants, which can easily cause resin to discolor. However, traditional spiro phosphate antioxidants typically suffer from low hydrolytic stability. Once moistened, they will hydrolyze in a short time and release phosphoric acid resulting in corrosion of manufacturing equipment. Revonox® 608, however, is the excellent solution to overcome this weakness. The special structure of Revonox® 608 not only maintains its high antioxidization efficiency but also possesses high resistance to hydrolysis and extremely high thermal stability at the same time. In fact, Revonox® 608 is the ideal phosphite antioxidant best suitable for engineering plastics manufactured over 280°C, such as polyesters, polyamides, polycarbonates etc.

Revonox® 420V

A phenol-free hydroxylamine primary antioxidant possessing anti-Nox functions. Including Revonox® 420V in the AO package can effectively mitigate gas-fading reactions of phenolic antioxidants. Simply speaking, Revonox® 420V is the best primary antioxidant in terms of color protection of polyolefins. Most importantly, the commercially available hydroxylamine antioxidants are derived from animal origin (tallow oil), while Revonox® 420V is a proprietary green antioxidant derived from palm oil certified by Roundtable on Sustainable Palm Oil (RSPO). It immediately eases the customer's concerns with substances from animal sources and complies with Chitec's core vision dedicating to green environment protection.

About us

Company details

Since its establishment in 1998, Chitec has been focusing on the research and development of specialty chemical applications for various industries, including electronics, medicine, automotive, and construction, etc. During this time Chitec has steadily built up its major product lines, such as photoinitiators, UV absorbers, antioxidants, flame retardants and others. To date, Chitec has not only set up two plants and one R&D center in Taiwan, but also has established a sales network that covers five continents. These are the critical building blocks of Chitec’s global success in the coating and plastics specialty chemical business. In 2010, Chitec was listed on Taiwan's Emerging Stock Market (stock code No. 3430) and became a public listed company. 

Innovation is a core value that Chitec continuously pursues and delivers to its customers. It explains why Chitec was able to file its first patent on a hydrolysis-proof antioxidant right after its establishment 16 years ago. The recently launched novel products, such as Revonox® 6 (a spiro phosphite antioxidant) and Zuran® 9 (an eco-friendly flame retardant), to name a few, have all undergone nearly 10 years of development with millions of R&D expenditure and facility investment. Strong R&D momentum and solid manufacturing capability are the key factors in Chitec’s success and its ability to compete with the centuries-old Western chemical industry. 

Eco-consciousness is the second pivotal value that drives Chitec in all its endeavors. Green concepts are adhered to in
every step from molecular design, raw material selection, process deployment to customer’s end application. A good example is Revonox® 420V, the first hydroxylamine primary antioxidant derived from a plant source. 

Chitec is also proactively meeting the global chemical regulations. In addition to the 100+ REACH pre-registered and 20+ fully registered substances, Chitec is also working on TSCA, FDA, CLP and GHS compliant projects as well as new chemical notification/registration initiatives in other countries to help global partners fulfill regulatory requirements. Many international enterprises would find it difficult to match the degree of Chitec’s commitment and investment in global regulatory compliance. 

Last but not least, breaking a stereotype that chemical business is always associated with danger, inferior work conditions, high energy consumption, substantial pollution and so on is the most significant mission of Chitec in the next decade. The best approach, also the third core value that Chitec has been upholding ever since day one, is sustainability. The Chitec plants have implemented measures that include the use of natural gas heating systems, top-notch waste water, air treatment and will eventually become carbon and water neutral. It is also hoped that these efforts will help the general public to realize that chemical industry can also be highly technology driven, safe, clean and eco-friendly.
