Cyasorb uv 3638 pdf
The heat conductivity of UHMWPE is improved by the addition of metal powders such as copper, aluminum, and bronze. CYASORB® UV-3638F provides superior UV protection for PET fibers with low color and low volatility. ASTM D3612 PDF - This standard is issued under the fixed designation D ; the number immediately 1 This test method is under the jurisdiction of ASTM Committee D27 on.
Due to resource limitations on translating chemical names into all official EU languages, thereafter. The method includes identifying a target window in an Abbe diagram comprising reference polymeric materials. If the fabricated parts are continuously exposed to high temperature, the addition of antioxidants is advisable. It is typically used in the stabilization of PET bottles and Electronic displays.
The present invention provides methods for controlling the optical properties of a light transmissive article. CYASORB® UV-3808PP5 is used in automotive lightweight external parts, structural & semi-structural parts and internal automotive parts.

CYASORB UV-3346 light stabilizer is sanctioned by Section 178.2010 of the Food Additives Regulations for use as a stabilizer in polypropylene and high density polyethylene at concentrations not exceeding 0.3 per-cent by weight of the polymer. Our portfolio contains two types of light stabilizers: Ultraviolet Light Absorbers (UVA) and Hindered-Amine Light Stabilizers (HALS). Ultraviolet stability may be improved by adding 1.0% CYASORB(9) UV-9 ultraviolet screener to the exterior exposed surfaces where aesthetic appearance is desired. cyasorb uv-3638 69 7 While the fluorescence quenching was comparable for invention and comparison compounds in the experiment of example 2 (see table 2) it is clear that in this experiment the invention UV-absorbers are still efficient while the comparison compounds are inefficient (except for the cyclic iminoester CYASORB UV-3638). In addition, the effect of two commercial UV absorbers, Cyasorb 1164 and Cyasorb 3638, at different concentrations on degradation of copolyester films was investigated to identify the performance of Cyasorb 1164 (triazine-based) versus Cyasorb 3638 (benzooxazin-4-one-based). TINUVIN performance additives for UV protection and durability are designed to protect and extend the lifetime of coatings. 3638 is based on a benzoxaxinone structure which delivers a short-term heat stability up to 350 °C and a long term heat stability up to 160 °C. PowerSorb™ 3638 is made to dissolve quickly in PET resin and to give a transparent appearance even with high dosage.
Degradation and Stabilisation of Aromatic Polyesters a temperature as was practical and with short melt-processing times, was recommended. PowerSorb™ 3638 is registered on FDA and is approved for food contact applications such as PET bottles and food wrap films.
