TinToll Polymer Stabilizers

 As one of the leading specialty chemical companies of polymer stabilizers, TINTOLL contributes to value creation by providing innovative and sustainable solutions to customers from many industries.

 

Leveraging more than 30 years of experience, TINTOLL developed innovative types of polymer stabilizers, including UV light stabilizers, antioxidants and polymerization inhibitors to extend service life, maintain structural integrity and enhance the performance of plastics through compounding, processing, fabrication and end use.

 

TINTOLL has three main UV light stabilizer additives lines. The first is PowerStabTM line which includes Benzophenones, Benzotriazoles, Benzonates and Triazines based UV Absorber; the second is PowerSorbTM line which includes hindered amine light stabilizers; the third is TinSorb™ UV-filters, they are designed for personal care formulations to protect skin and hair from the damaging effects of sunlight. TINTOLL’s powerful antioxidants are represented by the PowerNoxTM series, including hosphite antioxidants, Thioether antioxidant and HAPO (Hindered Phenols Antioxidants). And our polymerization inhibitors are available via PolyStabTM series. TINTOLL’s PowerCureTM Photoinitiators can be divided into radical photoinitiators and cationic photoinitiators. Radical photoinitiators can react differently under UV-irradiation. Depending on their reaction they are classified as Norrish Type I or Norrish Type II Photoinitiators.

 

Types of Polymer Stabilizers

Polymer Antioxidants

Polymers are easily oxidized when in contact with oxygen, leading to degradation. Thermal oxidation also occurs when high temperatures are used to manufacture end-use polymer products, affecting raw materials. Adding TINTOLL antioxidant additives, a type of stabilizer in polymer, during the manufacturing process is an effective solution to protect and stabilize polymer materials.

 

UV Absorbers

UV radiation leads to free radical formation and polymer degradation, which reduces the usability, functionality and safety of plastic products. UV absorbers serve as one of types of UV stabilizers for polymers and convert photochemical energy into harmless heat, protect UV-sensitive materials from damage caused by free radicals, and prevent polymer degradation. UV absorbers are often combined with other types of light stabilizers such as hindered amine light stabilizers HALS, for optimum weatherability.

 

Light Stabilizers

Exposure of plastics to light, heat and oxygen promotes the degradation of plastics, adversely affecting durability. UV radiation can break chemical bonds in polymers. This photodegradation eventually leads to cracking, chalking, color changes, and loss of physical properties such as impact strength, tensile strength, elongation, and others. In addition to the effects of UV radiation, the weathering of plastics also includes environmental factors such as temperature, precipitation, and the presence of pollutants.

 

Photoinitiators

Curing is a series of chemical and physical processes that a paint must go through after it dries. The coating must attach itself to the substrate either physically (adhesion) or chemically (cohesion), and must adhere to itself. It also requires chemical reactions such as "polymerization" (forming plastic). Applications of these polymer stabilizers include industrial coatings and graphic arts coatings.

 

UV Filters for Personal Care

Exposure to harmful UV radiation is linked to 90% of skin cancers, as well as premature skin aging such as wrinkling, loss of elasticity and pigmentation. UV filters are the stabilizer in polymer and active ingredients in sunscreen products that absorb, reflect, scatter and block UV radiation, thereby reducing the amount of UV light that penetrates the skin and reducing the risk of skin cancer.

 

Functional Additives

Functional additives are substances that are added to a product or material to enhance its performance or functionality. These polymer stabilizers can improve properties such as durability, strength, flexibility, heat resistance, chemical resistance, and more.

 

Industries

The chemical products industry is a broad sector that encompasses the production of a wide range of chemical substances. These types of polymer stabilizers are used in various industries and applications.
