LCP is 英文Liquid Crystal Polymer  shrink 写, in inner is liquid crystal polymer (LCP), is types new type polymer/macromolecule material, in add hot lower generally formed liquid 晶 形式, therefore therefore 而 名, it features 决定 LCP plastics raw materials use 处.

材 material introduction:

in 文名称: LCP engineering plastics

outer 文名称: Liquid Crystal Polymer

俗称: liquid crystal polymer (LCP)

formed separation: polymer/macromolecule material

property can: excellent resistant thermal properties and molding processing properties

features: flow property high, high machine strong/high degree

LCP plastics raw materials full 称LIQUID CRYSTAL POLYMER, in 文名称 liquid crystal polymer (LCP). it is types new type polymer/macromolecule material, in melt generally liquid property. this category of material tool has excellent resistant thermal properties and molding processing properties. polymerization methods melt polycondensation is 主, full aromatic LCP more solid versus polycondensation made polymer/macromolecule amount product. non full aromatic LCP plastics raw materials using/adopting or 二步熔 melt polymerization made product. year 连续熔 melt polycondensation made polymer/macromolecule amount LCP technology to development. liquid aromatic polyester in liquid lower due to its large separation is orientation, it has 异常规整 fiber structure, property can 特殊, products strong/high degree very high, 并不亚于 metal and 陶瓷. tensile strength and flexural modulus can ultra- 10 year development various thermoplastic property engineering plastics. mechanical properties, dimensional stability, optical property can, electrical property can, chemical resistant product property, flame retardant property, processing property good, heat resistant property good, thermal expansion coefficient relatively low. using/adopting mono different, made liquid polyester property can, processing property and price different. selection filler different, filler add amount different effect/influence it property can.

LCP advantages:

1, flow property high

2, dimensions property 佳

3, resistant solvent agent good

4, high machine strong/high degree

5, flame retardant property good

LCP applications:

1, speed device, 线圈, 开关, base/seat

2, parts, parts

3, automotive material outer parts

4, electronics use container

主意 and flow direction 垂直之 machine material property relatively 差

折叠LCP features:

A: liquid also can separation is solvent liquid crystal polymer (LCP) and hot liquid crystal polymer (LCP). front in solvent agent in liquid 晶态, rear temperature degree 变化而呈 liquid 晶态.

B: liquid crystal polymer (LCP) separation separation 之主链 rigid hard, separation between 堆砌紧密, in molding process in high degree orientation, therefore tool has 线膨胀系数 small, molding shrinkage low and non 常突出 strong/high degree and elastic property modulus and excellent heat resistant property, tool has relatively high negative deformation temperature degree, has can high 达340℃ above.

C:LCP resistant gas property, resistant property good, tool has excellent flame retardant property, can 熄灭火焰而不 again 继续进行燃烧. its and other grade to UL 94V-0 grade water 平. LCP plastics raw materials is anti safety property most good specialty plastics 之一.

D: generally hot property liquid crystal polymer (LCP) tool has relatively good flow property, easy processing molding. its molding product tool has liquid crystal polymer (LCP) has structure, resin tool has fiber property 质, in melt lower has high degree orientation, can to fiber reinforcement 效果. this is liquid crystal polymer (LCP) most 引人注目 features.

E: hot liquid crystal polymer (LCP) also can and multiple plastics made formed polymer blending material, this blending material in liquid crystal polymer (LCP) to glass fiber reinforced function, can large large improve/increase material strong/high degree, rigid property and heat resistant property and other.

F:LCP plastics raw materials density is 1.4~1.7g/cm3. liquid crystal polymer (LCP) tool has high strength, high modulus force property can, due to its structure features tool has reinforcement property, 因而不 reinforcement liquid plastics can to ultra- 普通 engineering plastics use separation 之几十 glass fiber reinforcement rear machine strong/high degree and its modulus water 平; if use glass fiber, carbon fiber and other reinforcement, more ultra- other engineering plastics.

G:LCP liquid crystal polymer (LCP) also tool has excellent heat stabilized property, heat resistant property and chemical resistant product property, for large more plastics in creep disadvantages, liquid material can 忽略不计, but also wear resistant, decrease abrasion property excellent.

H:LCP plastics raw materials tool has excellent electrical insulation property can. its electrical strong/high degree ratio generally engineering plastics high, resistant electrical property good. as is electrical appliances application made parts, in use temperature degree 200~300℃时, its electrical property can effect/influence. 而间断 use temperature degree can 达316℃ left right.

I:LCP plastics raw materials tool has corrosion resistant property can, LCP products in concentrated degree is 90% acid and concentrated degree is 50% alkali in lower 不会受 to 侵蚀, for/regarding industrial solvent agent, material 油, agent and hot water, rear by solvent understanding, 也不会引起应 force cracking.

injection molding process:

LCP molding temperature degree high, its product types different, melt temperature degree in 300~425℃ scope/range inner. LCP melt viscosity low, flow property good, and plastics 近似. LCP tool has small 线膨胀系数, dimensional stability good. molding processing conditions is : molding temperature degree 300~390℃; mold temperature degree 100~260℃; molding pressure 7~100MPa, pressure shrink ratio 2.5~4, molding shrinkage 0.1~0.6.

LCP main/primary applications

1)LCP plastics raw materials its tool has high strength, high rigidity, high temperature resistance, electrical insulation property and other separation excellent 良, by used for electronics, electrical, light fiber, automotive and and other field/area.

2) use liquid as formed fiber can 做鱼网, ******, use product, sheet/slice, light fiber 几显示材 material and other, also can made formed film, used for soft printing 线路, food packaging and other.

3)LCP plastics raw materials already used for micro container, can resistant high low temperature. LCP also can printing electrical sheet/plate, 人造卫星 electronics parts, gas machine parts ; used for electronics electrical and automotive machine parts or parts ; also can used for medical 方面.

4)LCP plastics raw materials can add high filling agent as is formed electrical 路封装材 material, 以代替 ring oxygen resin as ring framework 封装材 material ; as light cable 接头护 sleeve/set and high strength parts ;代替陶瓷 as chemical industry use separation in filling material and other.

5)LCP plastics raw materials also can and polysulfone (PSU), PBT, polyamide (PA) and other plastics blending made formed alloy, made parts molding rear its machine strong/high degree high, use 以代替 glass fiber reinforcement polysulfone (PSU) and other plastics, can improve/increase machine strong/high degree property can, also can improve/increase use strong/high degree and chemical stability property and other. currently positive in research will LCP used for device external sheet/plate, automotive outer made system and other.
