车 inner 门 手 造 type long strip/profile and 扣式门 手, its in long strip/profile 状门 手 is large separation automotive machine 厂 喜爱. long strip/profile 状门 手 due to fine long, and other 材质情况 lower relatively 扣式门 手 more easy by 拉断; in material selection 方面, long strip/profile 状门 手 need selection strong/high degree relatively high material, 如: electroplating PA; 扣式门 手则 generally selection strong/high degree requirements high material, 如: electroplating PC/ABS.

1.ABS resin

图 table/sheet 3 ABS材质门 手

ABS resin is inner 门 手 application relatively 早. due to force property can good, currently ABS resin already very less application to 门 手 in. inner 门 手 use ABS resin separation is general purpose type and heat resistant type, general purpose type ABS electroplating property can good, heat resistant type ABS resin heat deflection temperature (HDT) generally is 90-105℃, tool has good rigid property, tough property and flow property.

2.PC

PC is engineering plastics, its force property can excellent 良, is PC electroplating property can good, in use process in to 一定 限 made.

3.PC/ABS

图 table/sheet 4 帕萨特PC/ABS inner 门 手(毛胚 and electroplating parts )

PC/ABS resin is inner 门 手 development most fast, application most 广 材 material. PC/ABS resin is PC and ABS alloy, it tool has PC high strength and ABS easy electroplating property can, main/primary separation is electroplating and spray coating types type type. and spray coating PC/ABS resin versus ratio, electroplating PC/ABS resin surface more tool metal 感, more add high 档.

4.PC/PBT

PC/PBT is PC and PBT blending material, usually blending material rear, material supply. PC/PBT maintain crystallization material PBT chemical resistance and easy molding features, also non crystallization material PC tough property and dimensional stability. in inner, PC/PBT used for inner 门 手不太 more.

5.PA（ nylon ）

PA force property can excellent 良, its electroplating good and water is PA application in inner 门 手 两 large difficult 题. in outer, 如: Germany for force requirements very high, electroplating type PA in automotive in application 广泛. inner due to PA electroplating technology formed 熟, use very less! inner 门 手 use PA generally separation is type: spray coating type PA and electroplating type PA. electroplating type PA formed generally is PA+20%矿 material.

currently, market upper ultra- 10万 车, its 配置 车 inner 门 手 basic upper is electroplating type; its in electroplating type PC/ABS受 to large separation automotive machine 厂 欢迎, 包括: large 众, Di, and other.

PC/ABS resin widely used in 门 手 causes main/primary is: comprehensive property can excellent 良. comprehensive property can excellent 良我们 focus/key point 阐述一 lower:

1.PC/ABS comprehensive property can excellent causes

table/sheet 1: PC and ABS excellent disadvantages

我们知道PC is engineering plastics, PC advantages has machine strong/high degree versus for relatively high, heat resistant, water absorption low and other, 但PC electroplating 效果不太 good, processing properties 差; ABS is general purpose plastics, ABS electroplating good, chemical resistant 腐蚀, processing properties good, its machine strong/high degree 不够, heat resistant.

PC/ABS is PC and ABS alloy, PC/ABS结 combined advantages, comprehensive property can excellent 良!

北汽福田 尚红波 introduction: “ currently large more inner 门 手 basic is electroplating PC/ABS, inner 情况 说, electroplating PC/ABS still is inner 门 手材 material. Di and large will 门 手材 material electroplating PA改 is electroplating PC/ABS材 material, its main/primary causes is cost factors, is inner PA electroplating 线尚不 formed 熟”. machine main/primary material standards and made parts type as is material selection based on, again according to material features 进行匹配 selection. ”

table/sheet 2: PC/ABS in separation for electroplating and machine strong/high degree effect/influence

另一方面, PC/ABS in separation content for plastics property can effect/influence large （如 upper table/sheet 示）! balanced machine strong/high degree and electroplating property can, make material comprehensive property can most is difficulty/challenge! currently PC/ABS production can in ensure electroplating basic requirements conditions lower, can to PC content non high; from can large degree improve/increase material machine strong/high degree.

他们 is how to? from electroplating principle add analysis

2. how to in separation 不变 情况 lower, improve/increase electroplating property can?

如 upper 图 示, PC/ABS resin in butadiene distribution in versus in. and left versus comparison, right butadiene distribution more add uniform.

图 table/sheet 6 left 图: coarse front PC/ABS surface, right 图: coarse rear PC/ABS surface

chemical coarse 化时, butadiene 橡胶会 by solvent understanding, from formed a large amount of micro 孔. if butadiene distribution more uniform, that series PC/ABS coarse 化效果 good more.

图 table/sheet 7 coarse large 图

electroplating process is in plastics surface formed metal film. coarse 化效果越 good, same dimensions conditions lower PC/ABS surface large; surface large, plastics and metal 层 结 combined force large, electroplating 效果越 good! this is PC/ABS production improve/increase electroplating property can tips! another, butadiene distribution uniform also can 一定程 degree upper improve/increase PC/ABS machine strong/high degree.

currently, inner outer production PC/ABS although has very more, market upper main/primary has BASF Basf, Sabic, Bayer Bayer, Kumho day 丽, LG and other company. lower 面列举三 company commonly used PC/ABS grade （标红部 separation is used for 门 手 grade ）:
