Flame retardant properties of the test evaluation

In accordance with existing international standards or special provisions for some out trials to test the following parameters to assess the material Flammability:
(1) ignitability and flammability: It is the ease of ignition;
(2) the PVC flame retardant propagation speed: the flame retardant spread rate along the surface of the material;
(3) Fire resistance: the speed of the fire barrier material components;
(4) the release rate: the heat released during combustion of materials and the speed of release;
(5) ease of self-extinguishing;
(6) Health smoke: including raw tobacco consumption, tobacco smoke release rate and composition;
(7) the generation of toxic gases include: the amount of gas release rate and composition.

Use aluminum hydroxide flame retardant

Use of aluminum hydroxide:
Various aluminide materials, plastics, rubber and other flammable materials
 flame retardant additives, paper, toner surface, paint, toothpaste base, catalyst carrier, purifying agent, fluoride salt, drying, various types of molecular sieve, pharmaceutical industry, artificial agate, glass Marseille

G, construction materials accelerator fillers.
Aluminum hydroxide to improve the activity of the resin with aluminum hydroxide and workability, so that both the PVC flame retardant and filling double performance, which in plastics, rubber and other advanced composite materials to add this product, the product has a flame unfair smoke effects, and anti-leakage, anti-

Arc, wear resistance increased. It can be widely used in electrical cables, rubber, wire and cable insulation, sheathing layer, insulation materials, conveyor belts, etc.

Magnesium hydroxide

Retardant mechanism:
Magnesium when heated (340-490 degrees) decompose the surface absorption burning calories play a flame retardant; while releasing large amounts of water dilute combustible surface oxygen, decomposition of the active magnesium oxide attached to combustible surface is further prevents burning for

. magnesium hydroxide flame retardant in the whole process not only does not produce any harmful substances, and its decomposition products in a fire, while also able to absorb a lot of rubber, plastics and other polymer produced by combustion of harmful gases and smoke, constantly absorbing active magnesium oxide incomplete combustion

Burning melting residues from the combustion stop soon while eliminating smoke, preventing droplet, is an emerging environmentally friendly inorganic flame retardants.
Flame retardants can be classified according to the chemical composition of organic and inorganic flame retardants two categories. Organic phosphorus flame retardants are divided into two series, and halogen. Since the existence of organic flame retardants toxic decomposition products, smoke and other shortcomings, are gradually being replaced by inorganic flame retardants. No

Machine main varieties retardant aluminum hydroxide, magnesium hydroxide, red phosphorus, antimony oxide, tin oxide, molybdenum oxide, magnesium hydroxide flame retardant , zinc borate, in which aluminum hydroxide and magnesium hydroxide decomposition endotherm due to large and produce H2O can play the role of the absence of air, its oxidative decomposition

Material is high temperature material, so two kinds of flame retardants can not only play a role, but also can play a role in filling, it has no corrosive halogen gas and harmful gases, non-volatile, long lasting, non-toxic, smoke, do not drop characteristics.

Plastic additives and type of Performance

Plastics compounding, a small amount added to the synthetic resins or compounds, in order to improve the molding process or the performance of a given product of a class of chemical substances. Such materials dispersed in a mixture of synthetic resin or with, does not affect the molecular structure of the synthetic resin.
Performance
The main requirements of the plastic additive are:
Efficient: applications in plastics processing and can effectively play its proper function. Selection should be based on the additive mixing with the comprehensive performance requirements.
Compatibility: synthetic resin with better compatibility.
Persistence: in the plastic processing and application process is not volatile, non-bleeding and non-migratory and non-leaching.
Chemical stability: in plastics processing and the application process is not biodegradable, synthetic resins and other components with chemical reactions.
Non-toxic: no toxic effects on the human body.
Low prices.
Type
Plastic additives according to their specific function can be divided into seven categories: ① improve the processing performance additives such as heat stabilizers, lubricants, etc.. ② improve machining performance additives, such as plasticizers, toughening agents, etc. ③ additives improve the surface properties, such as an antistatic agent,

Coupling agent. ④ improve optical performance additives such as coloring agents. ⑤ improve the aging properties of additives, such as antioxidants, light stabilizers. ⑥ reduce the cost of plastic additives, such as extenders, fillers and the like. ⑦ pvc additive impart other specific effects, such as

Blowing agents, flame retardants, fungicides and so on.

The heat stabilizer stabilizer

Morphology PVC stabilizer solids, liquids and pastes. Typically, lead salt stabilizer more solid, liquid organic tin, calcium and zinc solid based, there are liquid and paste.
Lead salts: the first application of a heat stabilizers. With a more excellent long-term thermal stability, weather resistance and electrical insulating properties, but the impact of product transparency, toxic, initial coloring, easy sulfide contamination compatibility with PVC and poor dispersion. No lubrication lead salts

Therefore, with the metal soaps are used in combination. There are three basic varieties commonly lead sulfate, dibasic lead phosphite. Used for opaque PVC plates, tubes and wire and cable sheathing manufacturing.
Metal complex type: The most common one heat stabilizers. Often in liquid, paste or powder form with a pre-sale. Common varieties of barium - cadmium, barium - calcium - zinc, barium - zinc, calcium - zinc and calcium - magnesium - Asian tin - zinc salts of higher fatty acids. Such PVC heat stabilizer often

Organic auxiliary agents (such as phosphite, epoxy compounds, polyhydric alcohols, and phenolic antioxidants, etc.) and used to form products to adapt to different application requirements and processing of complex-type heat stabilizers.
Organic tin: These heat stabilizers main requirements for a variety of soft transparent PVC products. Common varieties of maleic acid esters, thiol esters and carboxylic acid salt. Among them, n-octyl tin maleate, S, S'-bis (isooctyl thioglycolate), di-n-octyl tin, can be used

Is non-toxic stabilizer for the food and pharmaceutical packaging materials.
