What is the difference between pe wax and OPE wax?

2021-12-18   Pageview:243

PE wax is non-oxidized wax, OPE wax is oxidized wax, with a certain acid value, oxidized wax molecular chain with a certain amount of carbonyl and hydroxyl, oxidized polyethylene wax is excellent new polar wax, so the compatibility with fillers, pigments, polar resins is significantly improved, lubricity, dispersion is better than polyethylene wax, but also both coupling properties.

Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl chloride, ethylene propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene, ABS and the demoulding of polymethyl methacrylate and polycarbonate. For PVC and other external lubricants, polyethylene wax has stronger internal lubricating effect compared with other external lubricants.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Excited state energy quencher means that after polymer molecules absorb light, their molecular structure will move to a high-energy excited state. Before photodegradation, the energy will be quickly and effectively quenched, so that the excited molecules will return to a stable ground state. The photodegradation aids, the representative varieties are nickel salt and salt complexes, certain acceptor amines and other compounds.

The role of the self-capturing agent is that the film-forming polymer compounds are oxidized to produce peroxides when heated, and the peroxides are subjected to the action of light to decompose into free radicals after absorbing high energy light quantum, and the free radicals further undergo Synthetic Hard Paraffin Wax auto-oxidative degradation reactions. , It can accurately and effectively trap free radicals before initiating auto-oxidative degradation to generate stable molecular compounds. The representative species are pyridine compounds, and photodegradation aids. Representative species are sneezing compounds, sulfide esters, phosphorous acid esters, etc. The peroxide decomposition system is effective in decomposing peroxides. To avoid the generation of active free radicals. The types of positive radicals initiated by positive radicals include o-hydroxy diphenylmethyl and o-hydroxy, substituted acrylonitriles, aromatic esters, oxalanilides, and triazines. Consume energy, thereby metabolizing harmful ultraviolet energy, and no longer destroy the polymer bonds of the film-forming material. The role of the ultraviolet absorber is to selectively absorb ultraviolet light and convert it into harmless heat or other low formamidines.

After the o-benzophenone compound absorbs ultraviolet light, it effectively reduces the molecular energy It is converted into low-energy radiation, so that the molecular bonds of the film-forming material are not damaged. O-Hydroxybenzotriazole compounds absorb ultraviolet light with a wavelength of 300~385mm, and convert the intramolecular energy into low-energy radiation, so that the molecular chain of the film-forming material is not damaged. The characteristic of this additive is that it does not absorb visible light and has a light color. , High absorption coefficient, good light stability, and good compatibility. The replacement acrylonitrile compound meter absorbs ultraviolet rays in the range of 310~320nm, and has a low absorption coefficient, good stability, and good compatibility with various resins. It can be used in fiber resins that are sensitive to short-wave ultraviolet rays, such as aromatic esters. Among them, salicylic acid is a general-purpose aromatic ultraviolet absorber. It has a high absorption coefficient for ultraviolet rays with wavelengths below 340nm. After light absorption, the molecules rearrange into a benzalkonium-resistant structure, and the absorption range is significantly increased; It is due to the absorption of visible light and the tendency to yellow.
