UV ADDITIVES MASTERBATCH

Product Description:

TACHNOFILL ADDITIVES has developed a complete range of UV Additive Masterbatches, with selected heat and light stabilizers, for every polyolefin application, all Polymers products exposed to heat, light and oxygen, are subjected to degradation, the degradation process can be retarded and the useful life of plastic products prolonged,  by the addition of stabilizers in the polymer, the most important reason causing degradation of plastics is the Ultra Violate radiation of the sun. the energy carried by this radiation initiates or accelerates chemical reactions chain in the polymer's molecules, causing chain - scission and cross - linking. as a result, the plastic product is loosing its properties and becomes brittle.

Special Features:

èThe careful selection and balanced formulation of different additives.

èThe excellent dispersion of the additives in the base resin.

èEasy processing without affecting the mechanical properties of the end

     Products.

èExtremely high weathering resistance and UV stability

èImprove films property without affecting the mechanical properties of the

     End products.

Applications And Recommendations:

Technofill Additives has provide range of UV Additive Masterbatch, are given for a number of polyolefin applications. in the following tables with indicative addition rates that should be considered a general guideline only.

Technofill Additives, modified versions or tailor-made products can be produced upon request.

Note:  Suggested addition ratio are general guidelines only. The appropriate addition for any application depends on the product, the area of exposure, the conditions of use, the required life-time, the presence in the product or the environment of pigments, additives or other chemicals and on other application specific parameters.

UV-Stabilization of Agriculture Films:

Technofill Additives has developed specializes in UV-stabilization of agricultural films. The company has its own experimental greenhouses, specially designed for testing new formulations of. UV-stabilizers, and can provide useful advice for this particularly demanding application. There are complete range of UV Additive Masterbatch proposed for this application:

è Based on Ni-Quencher with  UVA

UV10288-NiUVA / UV15382-NiUVA / UV20575-NiUVA  

It is suitable for 1 to 5 season agriculture films (depending on area and addition rate) Films stabilized with above products have a yellow & greenish shade and this Masterbatch are resistant to interactions with sulfur and sulfur containing pesticides

è Based on NOR-HALS  with  UVA

UV10288-NoRUVh / UV15382-NoRUVh / UV20575-NoRUVh

It is combined other special additives. It has been designed for use in greenhouses where sulfur and excessive pesticides are applied for pest control.

è Based on HALS and Co-Stabilizers

UV10288-UVhCo / UV15382-UVhCo / UV20575-UVhCo 

has been developed with the purpose of improving the resistance of H A L S to pesticides. H A L S are reactive alkaline molecules-this is why they are deactivated by acidic pesticides and their residues. by introducing in the film compounds with higher alkalinity which react with the pesticides and neutralize them, the damage to H A L S is reduced and the life of the film is prolonged. these compounds are called Co-Stabilizers. 

Co-Stabilizers diffuse the light, imparting to the film a slight milky aspect. This has in most cases a positive agronomic effect (more uniform distribution of light in the greenhouse, less burnings of the plants due to direct sun rays). For this reason, H A L S + Co-Stabilizer formulations are highly recommended in areas with strong sunshine, high temperatures and high usage of pesticides

Ø  “It should be noted that Co-stabilizers improve the resistance of the film against normal use of pesticides but do not offer adequate protection in case of use of sulfur or excessive application of pesticides"

è Based on HALS and UVA

UV10288-UVhUVA / UV15382-UVhUVA / UV20575-UVhUVA 

Are recommended for 01 TO 02 seasons, provided, and avoid excessive use of pesticides or sulfur, as these products interact with HALS and can be limit their efficiency.
