1. what is 火? plastics principle

火 is “燃 material ” material and oxygen gas reaction, generate hot amount and 火焰. in this type of lower, plastics is 燃烧 燃 material. plastics principle can simple understanding is: plastics in has carbon and hydrogen, it is 维持火焰 material 质. plastics and oxidation agent between high temperature oxidation also reaction generate gas oxidation material, this type of mixed combined material is 烟雾. generate 火焰, generate hot amount 维持燃烧.

Nhiệt: hot
Nhiệt phân nhựa: plastics hot understanding
Khói và mùi: and odor
Ngọn lửa: 火
Oxi và không khí: oxygen gas and gas
Khí cháy: gas 火焰

2. various Common flame retardant plastics

2.1. MC

MC is nylon types 形式, melt inner amine mono C6H11NO mono made formed, use alkali property combined material as is catalytic agent, use active agent and other additives formed copolymer mono mixed combined material. MC plastics features is surface hardness high, flexibility property good, resistant strong/high degree high, impact resistant property good, resistant fatigue, wear resistant, resistant property non good, especially is flame retardant property high.

MC plastics used for manufacturing wear resistant 垫, heavy parts, and related machine 械, flame retardant MC sheet/plate and other and other.

2.2. POM

POM（ polyoxymethylene (POM) ） plastics also is shrink aldehyde, poly shrink aldehyde, polyoxymethylene (POM) and other different 名称, its chemical is (CH2O)n, density is 1.41～1.42g/cm3, melting point is 175℃. due to crystallization content high, it white, it can made formed multiple color. this type of plastics Germany chemical 家赫尔曼·施陶丁格于1953 year 发明.

POM plastics surface hardness high, low, tool has good impact fatigue and impact resistant property can, friction coefficient low, tool has lubricated property. POM plastics although shrinkage rate relatively high, dimensions maintain stability. good electrical property can, resistant solvent agent property, force cracking, bubbles and other features is POM plastics advantages. due to its resistant strong/high degree, add in material upper outer force remove rear, material still can to 原 形状.

POM plastics tool has good flame retardant property, 燃烧时火焰呈清澈 蓝 color, 无煤烟释放, plastics 变黑, tool has aldehyde 特征 刺激 property odor. therefore, it can for 鼻子, and 眼睛造 formed 刺激.

POM plastics most Common application areas is machine 械, electrical and electronics manufacturing, medical, food processing and other industry manufacturing toys, 窗户, water tank, water and other and other.

2.3. PP

PP plastics （ polypropylene (PP) ） chemical is (C3H6)n. in positive conditions lower, PP plastics appearance transparent white, color, 无臭, 无味, 无毒. due to PP plastics in production in application 广泛, therefore it by add color additives.

PP plastics machine strong/high degree high, comparison hard, has PE plastics that flexibility, can tensile, therefore by made formed fiber. has small or 刺穿时, PP plastics very easy 撕裂. in addition, this type of plastics can 承受100摄氏 degree above temperature degree, ratio PE tool has more good heat resistant property, and also tool has excellent 越 点 insulation property and chemical property.

about/regarding can property, PP plastics heat resistant property good, therefore ratio other plastics more flame resistant 烧. 燃烧时, it generate color 火焰, tool has 塑流, has similar odor odor.

PP plastics Common used for manufacturing packaging industry, fiber weaving, use film, plastics bottle and other need heat resistant property product.

2.4. PA

PA plastics （Polyamide - polyamide (PA) ） tool has long polymer chemical 式, has amine mono 元（N-H-C=O）. this polymer is through acid and amine polymerization methods obtain. 例如: PA66 is through adipic acid and hexamethylenediamine chemical reaction obtain.

PA plastics tool has good heat resistant property and lubricated property can, machine strong/high degree high, hardness high and tough property good. in addition, it also tool has excellent wear resistance, good chemical resistance, property and impact resistant property.

PA plastics tool has excellent flame retardant type, especially is, it by add flame retardant glass fiber (GF) rear, this advantages 进一步 to improves.

PA plastics by suitable for manufacturing resistant abrasion 垫, heavy parts, construction industrial, 造船, machine and other use 事业.

2.5. ABS

ABS plastics （ acrylonitrile butadiene styrene ） chemical is (C8H8)x(C4H6)y(C3H3N)z). 原生ABS plastics tool has transparent white, hard easy 碎.

ABS plastics features is impact resistant property good, dimensional stability good, can color, molding property good. ABS plastics has 助于良 good machine processing, machine strong/high degree and hardness high, water absorption low. in addition, ABS plastics also tool has good corrosion resistant property, simple, 无毒无味.

自发明ABS plastics 50 more year, ABS plastics by manufacturing 商不断 research and 改进, improve/increase it flame retardant property. currently, ABS plastics tool has excellent high temperature resistance features, therefore to flame retardant plastics 时, 我们立即想起 it.

electronics, use electrical appliances, automotive industrial, 摩托车 industrial, packaging industrial, construction material and other and other is ABS plastics Common application. in addition, due to good flame retardant property, ABS plastics by used for manufacturing electrical and electronics equipment outer housing/shell （如 electrical and electrical 脑）.

3. how to reinforcement plastics flame retardant property can

positive 如文章开头 提 to, has types plastics is 不燃, is tool has or more or less can can force. is reinforcement plastics flame retardant property, manufacturing 商会添 add flame retardant additives, this can or has retardant 止 火势蔓延.

flame retardant additives main/primary function 包括:

+ improve/increase material temperature degree
+ decrease slow speed degree
+ decrease/reduce generate hot amount
+ decrease 缓火势 蔓延

is to this features, flame retardant additives need and plastics dispersion good, reduce plastics property can, 也不引起 machine 腐蚀.

3.1. flame retardant additives function mechanism

Pha khí: gas versus
Pha rắn: solid versus
Nhiệt lượng: hot amount
Khói: 烟雾
Sản phẩm cháy: product
Gốc tự do hoạt động: 自由基 active property
Khí cháy: gas
Lớp than phủ bề mặt: cover/cap surface 煤层
Vùng nhựa bị nhiệt phân: plastics hot understanding 区

3.2. flame retardant classification

卤系 flame retardant （Cl, Br）

this material separation understanding generate 自由基Br°, Cl°, it and active property 自由基（O°, HO°, H°）发生 reaction, formed resistant use, flame resistant material.

例如: bromine ether (DECA), bromine di A (TBBA), bromine ring 十二烷 (HBCD), TBBA- di -(2,3-二 bromine 丙烷), chlorine wax

磷系 flame retardant

燃烧时, combined material generate acid, this type of formed separation has in material 体周围形 formed hard inert property 炉渣层, has anti oxygen gas 接触.

例如: poly acid (APP), 红磷, poly amine poly acid salt (MPP), acid ester, acid ester, di A acid ester (BDP)

含 nitrogen flame retardant

参 and formed inert property process, has anti oxygen gas. it 们燃烧时也会 generate amount inert property gas 体（N2, NO2）, will oxygen gas from material in 排出.

例如: poly amine poly acid salt (MPP), poly amine acid (MC)

无 machine flame retardant

燃烧 rear material is inert property solid combined material, therefore it has 助于形 formed inert property 渣层. has combined material tool has hot separation understanding features generate water, reduce process temperature degree.

例如: hydrogen oxidation aluminum, hydrogen oxidation 镁

4. EuroPlas plastics flame retardant

Europlas plastics flame retardant additives tool has color property can high impact resistance property, good heat stabilized property and dimensional stability and good resistant scratch property. product combined UL 94 standards: V0, V1 and V2, ensure processing and use product quality. below/following is flame retardant additives 一 突出 features:

- through as used for plastics surface mechanism decrease 缓火势 蔓延
