Description:UV-MDLXXVII est ultraviolet lux absorber (UVA) de hydroxyphen triazine classis exhibens ipsum humilis volatility et boni compatibility cum varietate polymers, co-additives et resin compositionibus ad consequi a superiore resinat, quam conventionum ad consequi ad altiorem resistentiam et Polyters ad consequi ad altiorem resistentiam quam conventions ad consequi ad altiorem resistentiam quam conventions ad consequi, quam ad consequi altiorem resistentiam, quam conventionum Benzotrials absorbers.UV-1577 is suitable for all kinds of high performance polymers and alloys, such as PET,PBT,PC (linear and branched), polyether ester, PMMA, acrylic copolymers, PA, PS, SAN, ASA, polyolefin, reinforced or not reinforced, filled or unfilled, flame-retardant or non-flame-retardant, transparent, translucent, etc.
Usus:Dxsorb MDLXXVII adhibetur ut lux stabililer / UV absorber pro polyethylene phthalate Polymers animo in usum in contactum cum cibum. Minimum volatile UV lux absorber et stabililizer.allows polycarbonates polyesters ad consequi altiorem resistentiam tempestas quam conventional benzotriazole UV absorbers. Minimum tendentia ad chelate concedit usus in polymer formulations quibus catalyst residua. Dxsorb MDLXXVII (UV-MDLXXVII) adhibetur ut lux stabililerit / UV absorber pro polyethylene phthalate Polymers animo pro usu in contactu cum food.uv-MDLXXVII est princeps perficientur ultroviolet lumen absorber continet hydroxyphen triazine coetus. The performance of UV-1577 can be optimized when combined with HALS.Polyalkene terephthaletes and naphthalates, linear and branched polycarbonates, modified polyphenylene ether compounds, and various high performance plastics. Pertinet Applica- tars etiam includit usum homum-, co-, aut terpolymer structuram in in thermo- plastic materiae. Polymer mixtionis & Alloys, ut PC / Abs, PC / PBT, PPE / IPS, PPE / PA et Copolymers et retardetur, repleti et / vel flamma retardatur, quod potest esse transparent, translucens et / vel pigmentatus.
Detailed introductio
UV MDLXXVIIEst late solebat impediebat Amine lux stabilitorque (Hals), quod praebet efficax tutela contra Damaging effectus de ultraviolet (UV) radialis et oxidative degradation. Hoc est communiter assuetudo ut dicitur in variis industries, inter plastics, coatings, adhesives, et textilia, ad augendae diuturnitatem et lifespan materiae patere velit environments.
UV-MDLXXVII, etiam notum per eius eget nomine bis (1,2,2,6,6-Pentamethyl, IV-piperidinyl) Sebacate, pertinet ad impediebat Amine familia de lumine stabilitiis. Operatur per unicum mechanism agendi ne UV-adductus degradation in polymers. Cum expositae UV radiation, UV-MDLXXVII subeundes reversible phototransformation, captos liberum radicalis et neutralizing eos. Haec prohibet degradationem Polymer et subsequentem damnum corporis proprietatibus, ut color evacuatur, embrisslment et superficiem rimas.
Unus ex clavis commoda UV-MDLXXVII est eius versatility et compatibility cum amplis polymers et materiae. Non potest esse in thermoplastics, ut polyolefins (eg, polyethylene et polypropylene), polyters, polyycarbonates, et PVC (polyvinyl chloride). Est etiam effective in thermosetting resinam, ut Polyurethanes, epoxy resinam et unsaturated polyester resinam. Hoc versatility facit UV-MDLXXVII apta variis applications, inter films, fibris, fingitur partes, coatings, adhesives, et sealants.
UV MDLXXVII offert optimum scelerisque et oxidative stabilitatem, cursus et diuturnitatem et efficaciam et sub dura conditionibus et longum differentur ad UV radialem. Potest resistere elevatum processus temperaturis in polymer productio aut articulum praeparatio sine significant degradation.
Ad consequi meliorem perficientur, UV-MDLXXVII est saepe solebat cum aliis lucis stabilizers, ut UV absorbers et antioxidants, ut providere synnergistic effectus. Hoc combination adjuvat ad maximize UV praesidium et altiore diuturnitatem materiae.
Est momenti ad considerandum specifica dosis et formula guidelines ad incorporating UV, MDLXXVII in diversis applications. Manufacturers et users debet referri ad technicas litterae, uber guidelines, et industria optimum exercitia pro suadeo usu campester.
UV MDLXXVII est plerumque considerari tutum, cum tractata, repono, et usus secundum applicabiles ordinationes et guidelines. Tamen, quod est semper advisable ad consule salute data sheet (SDS) et propinquos meos cum loci ordinationes ad curare propriis tractantem et arbitrio procedendi.
Applicatio
UV MDLXXVII est chemical compositis, quod vulgo quod Tinuvin MDLXXVII vel bis (1,2,2,6,6-Pentamethyl, IV-Piperidyl) Sebacate. Est impediebat Amine lux stabilitor (Hals), quod est in variis industrias et applications. Hic sunt quidam ex eius principalis usus:
Polymer Stabilization:UV MDLXXVII late usus est ut lux stabilitorque in polymer products. Is protegit Polymers, ut plastics et coatings, ex nocivis effectus of UV radialis, inter degradation, color, et damnum ex proprietatibus. Is iuvat extend lifespan et ponere speciem polymer, secundum materiae.
Coatings et pingit:UV MDLXXVII additur ad coatings et pingit ad amplio eorum resistentia ad UV degradation. Non adjuvat in prohibendo color evacuatur, Glossa reductionem et superficiem chalking per nuditate solis.
Plastics:Est in variis plastic applications, comprehendo polyolefins (ut polyethylene et polypropylene), Polyurethanes, et PVC (polyvinyl chloride) products. UV MDLXXVII auget tempestas et lucem stabilitatem harum plastics, permittens eos ponere corporis proprietatibus super extenso tempora velit nuditate.
Adhesives et sealants:UV MDLXXVII est incorporatus in adhesives et sealants praesidio eos a UV-adductus degradation. Hoc adjuvat ad tenaces vires et extend in ministerium vita horum products, praesertim in velit applications.
Fibris et textilia:UV MDLXXVII est etiam in texit industria praesidio textilia et fibris ab UV radialis damnum. Non prohibet color, fibra degradationem et damnum mechanica vires per UV nuditate.
Est momenti ad note quod in specifica amounts et applicationem modi of UV-MDLXXVII potest variari secundum specifica productum et industria. Nulla et users of UV MDLXXVII semper sequantur commendatur guidelines et ordinationes propriam tractantem et usus.
