PVC composite heat stabilizer

Stabilizers to an increased solution, gel, solid, chemical stability of the mixture. It can slow down the reaction, to maintain chemical balance, reduce surface tension and prevent light, thermal decomposition or oxidative decomposition effect. Generalized chemical stabilizers wide range of sources, mainly based formulation designed to organic pigments  designers, the flexibility to use any chemicals to achieve the purpose of product quality and stability. Narrowly speaking, mainly refers to maintaining high polymer plastics, rubber, synthetic fibers such as stability, to prevent its decomposition, the aging of the reagent. PVC sheet composite heat stabilizer is a compound of lead from the dust symbiotic (Co-reaction) reaction technology, to ensure thermal stability of the base element composition (such as two. Three salt, metal soaps) in the reaction system was in the beginning of the body Eco grain size and mixed with various lubricants to ensure the  potassium stearate product groups were thoroughly mixed uniformly PVC products widely used performance indicators:

Zinc borate Applications

Overview of zinc borate
Boron-based flame retardant is one of the earliest use of flame retardants, inorganic flame retardants are also important, which is characterized by good thermal stability, low toxicity, smoke, and other flame retardant compound works well, after adding combustion of materials significantly reduced smoke density, and a halogen-containing flame retardants, ozone

Of two antimony compound effect is obvious.
Application of zinc borate
Used in PVC cable, PP, PE, EVA, unsaturated polyester, epoxy resin, natural rubber, synthetic rubber, chloroprene rubber, expandable fireproof coating.
1 Zinc borate can be used as antimony oxide or other halogenated flame retardants multi-functional synergistic additives can effectively improve the flame retardancy and reduce the generation of smoke when burned, and you can adjust the rubber products, chemical, mechanical, electrical and other aspects of performance.
(2) halogen-containing flame retardants such as partial or complete substitute green, zinc borate flame retardant, is being widely used in plastics and rubber direct processing, such as PVC, PE, PP, reinforced polyamide, polyvinyl chloride resin, polystyrene , epoxy resin, polyester resin, vinyl and natural

Rubber, styrene butadiene rubber, chloroprene rubber. Can also be used in paper, fabric, decorative panels, floor coverings, wallpapers, carpets, ceramic glazes, fungicides, paint production in order to improve flame retardant properties.
3 based on other properties of zinc borate, but also for preservation, far-infrared absorption, timber pest biocontrol treatment and other fields.

Zinc borate brief

Micro-crystalline zinc borate as a white powder, non-toxic, insoluble in water and common organic solvents, slightly soluble in water, soluble in dilute acid, poorly soluble in sodium hydroxide, soluble in acid and alkaline ; thermal stability, fine grain size, dispersion and strong, the main feature is flame retardant,

Smoke suppression. Can also be used alone as a flame retardant material with a variety of flame retardant compound used with improved efficiency, and the price is cheaper, less dosage, can significantly reduce unit production costs and improving economic efficiency.
Range widely used in plastics, rubber, paint, ceramics, lubricants, wire and cable, electrical insulating materials, electronic products shell, etc., depending on the product and the flame retardant requirements can be fully or replace expensive 50-80% oxide antimony. In the fire-retardant coatings

The physical properties of titanium dioxide

The physical properties of titanium dioxide: the relative density, melting point and boiling point, dielectric constant, conductivity, hardness, moisture absorption,

thermal stability.
Relative Density
The relative density of the titanium dioxide with the crystal morphology, particle size, chemical composition, in particular the amount of the size and surface

treatment, in the manufacturing process, with the calcination temperature and calcination time to improve the growth of the extension.
Melting and boiling points
As tio2 anatase type titanium dioxide and a plate at a high temperature are converted into rutile, their melting point and boiling point does not actually exist.
Permittivity
As a high dielectric constant of titanium dioxide, it has excellent electrical properties. Under the effect of external electric field, the interaction between ions,

forming a very strong electric field locally. In the electric field effect, the ion outer electron orbits strongly deformed, ion itself also will be a great

displacement. Crystalline titania contained trace impurities and so a great influence on the dielectric constant.
Conductivity
Performance of titanium dioxide having a semiconductor, the conductivity increase with temperature increases rapidly, but also very sensitive to hypoxia.
Hardness
Hardness and crystal structure of titanium dioxide on, in the production and product purity and calcination temperature, high temperature sintering is easy, hardness

will increase. Because of the hardness of rutile titanium dioxide, difficult pulverization nozzle orifice and thus the higher the wear, the wear of the rolls is large,

it unsuitable for chemical fiber matting and gravure printing.
Hygroscopic
Although the hydrophilic titanium oxide, but not too strong moisture absorption, moisture absorption of anatase larger than rutile. Hygroscopicity titania surface

treatment with the nature of the treatment agent, but also on the size of its surface area have a certain relationship, large specific surface area is slightly

hygroscopic.
Thermal stability
Titanium dioxide is the thermal stability of compounds of intense heat under vacuum there is a slight loss of oxygen phenomenon, accompanied show dark blue, the

reaction is reversible, the cooling will be restored to the original white.
