UV masterbatch is mainly produced by antioxidants, light stabilizers （HALS）, UV absorbers, and carrier resins. The formula of master batch UV is different according to different products and different UV test standards.
① When plastic products are used outdoors, oxygen aging will occur, and polymers will undergo auto-oxidation reactions, which will accelerate the aging of plastic products, so antioxidants are usually added to the formula.
② Light stabilizer: effectively inhibits the damage of ultraviolet rays to polymer chains and prolongs the service life of products.
③UV absorber: selectively absorbs ultraviolet rays (290-400nm), converts them into harmless heat energy, and reduces the breakage of plastic molecular chains.
The molecular structure of polymer materials is one of the inherent reasons for their aging. Specifically, cross-linking may occur between polymer chains, making them hard, brittle, and losing elasticity; so aging is a common phenomenon in polymer materials.
After long-term aging under temperature, humidity, optical fiber, etc., plastic products mainly have the following changes:
Such as discoloration, darkening, spots, powdering, etc.
Such as density, refractive index, light transmittance, etc.
such as tensile strength, elongation, impact strength, etc.
Such as volume resistivity, surface resistivity, etc.
Plastic products exposed to sunlight will have the above phenomena due to the long-term influence of the natural environment, which greatly shortens the service life and reduces the beauty and safety of the product. Adding UV stabilizer masterbatch can solve the discoloration and embrittlement caused by light, oxygen, wind and rain forest, etc.
Do your plastic products fade, powder, etc. due to long time in outdoor? The product looks ugly and has low texture, resulting in a decline in brand trust and loss of customers.
Imagine that the artificial turf you laid in the yard has lost its color and even has different shades in just half a year. In more serious cases, even the shedding of grass fibers can produce a lot of microplastics. This is because the color of the turf has a low light resistance level. On the other hand, ultraviolet rays destroy the structure of the plastic. Similarly, we can see many examples outdoors, such as trash cans, car bumpers, drain pipes, plastic tables and chairs, etc.
Adding weather-resistant masterbatch can reduce the damage caused by ultraviolet rays to the product, extend the outdoor service life of the product, and improve the durability of the product.
| Application fields | Product Types |

►What is the typical addition ratio for anti UV masterbatch?
Usually, the addition ratio is between 1-5%. The thicker the part, the lower the addition ratio. Similarly, to achieve the same effect, the thinner the part, the higher the addition ratio.
►What is the effective content of UV masterbatch?
Depending on the application requirements and testing methods, the effective content of UV masterbatch ranges from 5-30%.
►What legal and regulatory requirements does masterbatch UV comply with?
Can it comply with regulations such as ROHS, REACH, and FDA?
►How long does it take to produce a weathering solution?
Once we've confirmed the specific application and testing requirements, Stander can typically provide a solution the same day.
We will be based on different products of customers, such as different main resins: PP, PE, TPU, TPE, PA, PET, PC, ABS, etc., different products: agricultural films, non-woven fabrics, artifical turfs, injection molding products, automotive interiors, etc. Different application scenarios: Saudi Arabia and Russia and other regions. Different test standards.
With our experience, we will provide customers with professional UV weather-resistant masterbatch solutions from various angles to extend the outdoor use time of the product and improve the cost-effectiveness.
