Professional plastics ABS who are concerned about Micro letter public; xmkeyuan, stamp, blue tuned!

This article is general plastic last post, written in front of four common plastics: PE, PP, PVC, PS. If you like it, make will continue to write about introduction to engineering plastics and specialty plastics. This article, from ABS introduction, classification, development, process, alloy, and some common defects in seven areas to introduce.

A, ABS profile

My name is ABS, scientific name: acrylonitrile-butadiene-styrene, English name: Acrylonitrile Butadiene Styrene. Normal to light yellow or milky white grain non-crystalline resin, fat little more than water:1.02-1.08g/cm3. Production is currently the largest and one of the most widely used polymers. I am PB, PAN, and the combination of PS and, therefore, both tough and hard and rigid balance characteristics (mechanical properties).

A, representative propylene nitrile : propylene nitrile provides hardness, and heat sex, and acid alkali salt , chemical corrosion of nature; and d II en copolymer can business have NBR , its has good of resistance oil sex, Hardy sex, wear sex, and electric insulation performance, and in most chemical solvent, Sun and hot role Xia, performance compared stable.

NBR acrylonitrile content (%) include 42~46, 36~41, 31~35, 25~30, 18~24 and other five. More acrylonitrile content , resistance to oil the better, but cold fall .

B for butadiene : for ABS resins to provide low-temperature ductility and impact resistance, electrical properties , butadiene will decrease too much resin hardness, gloss and liquidity ; improve the styrene content can increase strength , elongation decreased adhesion variation; styrene content 50%~70% of butadiene-styrene copolymer resin, but pan said high-styrene rubber;

And styrene, styrene-butadiene rubber , styrene-butadiene rubber and includes:k-resin, SBS and SBR , with very good wear resistance, heat resistance, aging resistance.

K-resin (butadiene-styrene transparent impact resin ): anionic polymerization of a block copolymer synthesis of technology, an amorphous polymers, high transparency, high gloss, impact resistance, good processability;

SBS (Thermoplastic Elastomer):, a combination of plastic and rubber properties, with excellent electrical properties of tensile strength, elasticity, and permanent deformation, Flex and good compression, and surface friction.

SBR: divided according to production methods, styrene-butadiene rubber emulsion polymerization, solution polymerization styrene-butadiene rubber and the powdered styrene-butadiene rubber

1) polymerization of butadiene-styrene rubber : with wear-resisting, cold and lower heat build-up, shrinkage , color, less ash, high purity and curing speed advantages, and have small rolling resistance and wet skid resistance and wear resistance performance advantages;

2) emulsion polymerized styrene-butadiene rubber : processing performance , vulcanized rubber abrasion resistance , tensile strength, tear strength and resistance to aging well;

3) PSBR (powdered styrene-butadiene rubber): designed for modified asphalt production of powdered styrene-butadiene rubber, in addition to styrene-butadiene rubber significantly improved low temperature performance characteristics, powdered styrene-butadiene rubber or significantly improving the high temperature performance of asphalt ;

S for styrene : ABS resin provides hardness , process flow and surface Finish ;

With acrylonitrile copolymers, is AS resin , AS resin is a hard, transparent material. Styrene content more and more hard, transparent and easy to process AS resin; acrylonitrile is high (AS) better chemical and thermal stability.

If100% styrene , polystyrene , another common plastics. PS has a high degree of transparency, light transmission rate of up to 90% per cent, good electrical insulating properties, easy to be colored, processing and good liquidity, good rigidity and good chemical resistance.

Is ABS have different properties of each component, so when ABS (acrylonitrile-butadiene-styrene) PAN and the PB and the PS unified when both tough, hard, just balanced by excellent mechanical and chemical properties. Composing content performance with different combinations in different ways, showing different ABS.

Second, history

Third, the ABS classification

Because I am a combination. And widely used, therefore, generally in accordance with my ability to describe me (classification). Such as: General (including resistance level) level, transparent, heat-resistant, flame retardant, plating grade, structural foam, and modified ABS and so on.

Four,ABS production technology

For me the origin of this is a long story. At present, the main emulsion polymerization and bulk .

Emulsion polymerization : The method is the polymerization of styrene with acrylonitrile AS, and then in a State of emulsion polymerization of butadiene into the ABS, this process AIDS remains more, yellow color, most products are for sale in the market this production (LG, CMO, Jilin Chemical, BASF, etc).

Bulk: continuous body ABS production technology including Sol, polymerization, polymerization, devolatilization and granulation 5 steps. Technology advantages:

1. the continuous production, the process is simple

2. less equipment, low investment, easy

3. less waste, less pollution, energy-saving and environmental protection

4. switch products

Current United States DOW and Sinopec Shanghai gaoqiao is using this technology. Emulsion polymerization products, bulk product color is white, but poor gloss; a wide temperature range.

Five, ABS alloy

It is because, I am a combination. Therefore, the easy compatibility with other races, so I'm usually with other plastics, get a new plastic alloys modified, thereby greatly improving my performance. Common ABS alloys are ABS/PC, and ABS/PA, and ABS/PBT, and ABS/PVC , and so on. There is also ABS/PSU, and ABS/EVA, and ABS/PVC/PET, and ABS/EPDM, and ABS/CPE, and ABS/PU alloys.

Six, the application of ABS

With such a comprehensive ( impact resistance, high stiffness, oil resistance, low temperature resistance, chemical resistance and electrical properties, as well as easier processing, low price ) I must be an integral component of this world, so in the electronic and electrical, instrumentation, automotive, construction and industrial areas, I am everywhere.

Seven, ABS and its alloy of some common problems and solutions

In order for me to let everyone know fuller, so I cannot praise myself, will let people see where I is insufficient. After all, it is a tough man, also has its weaknesses (NBA player LeBron James will cramp) so, I will inevitably produce some problems ( Aging, corrosion and stability ). But, with the awareness of themselves, also found ways to overcome these shortcomings.

1.ABS stress analysis

ABS is amorphous polymers, varying degrees of stress came from the orientation and the hot and cold contraction. Filamentous cracks, cracks includes parts for surface micro-cracking, white, cracked and parts sticky mode, channel stick mold caused by cracks, what these reasons how to solve?

3.ABS performance issues

Any plastic used in the process would encounter some problems, such as Aging, corrosion, poor stability , the source of these problems, is due to b, butadiene , after polymerization of unsaturated and health ——“ C=C” exists, making it less stable. Here to introduce its causes and some of the methods. Specific details, you can click on the blue links:
