Extrusion ABS
Overview
Polymer processing is mainly divided into two major groups: extrusion and injection molding.
starex Extrusion ABS is formulated to provide excellent mechanical properties, extrusion stability, vacuum formability and chemical resistance. We are meeting the customer's needs by supplying various Extrusion ABS resins so that the proper materials for refrigerator liners, pipes, bathtubs and suit cases can be selected.
Features
1) Non-Toxicity
As Extrusion ABS resin may contact to many of foodstuffs, water, etc., non-toxicity is one of the most important properties. starex Extrusion ABS is non-toxic to use for any kinds of application.
2) Well Balanced Mechanical Properties
The application of Extrusion ABS resin is mainly for parts which need excellent tensile and impact strength. starex Extrusion ABS shows not only high tensile strength, high impact strength and high flexural strength, but also good impact strength at low temperature.
3) Excellent Extrusion Stability
One of the major problems of sheet extrusion is the variation of output with time. If the output varies with time, it is very hard to control uniform thickness, gloss and mechanical property. As starex Extrusion ABS has wide processing window and special melt flow characteristics, customers not only can extrude sheet uniformly even in the situation of small unwanted condition change but also can easily setup the extruding conditions.
4) Good Vacuum Formability
Recently, the vacuum-formed product including refrigerator liner have been changing to more complicated design. If General ABS which has not excellent extensional viscosity has been used, the thickness distribution is not so even, and excessively thin forming part might occur. Since starex Extrusion ABS resin shows excellent extensional viscosity at forming temperature, it has very stable extensional property which means more even wall thickness during forming process. Therefore starex Extrusion ABS resin can be vacuum-formed with thin sheets which can reduce the total production cost.
5) Good Chemical Resistance
When Extrusion ABS resin is applied on pipes, refrigerator liner and containers, it should display a high level of resistance to freon, food stuffs and oil. starex Extrusion ABS resin has better resistance against above chemicals than General ABS. So if you use cyclo-pentane or CFC-11 as blowing agents on refrigerator, starex SV-series can provide better performance without crack. But in case of HCFC141b, starex ABS ES-series is more adaptable.
6) Stable Color to Sunlight
Generally, ABS material is used in indoor equipment, but it is sometimes exposed to sunlight during transportation, stacking in field. So color stability is another requiring property of ABS material. starex Extrusion ABS resin has good color stability to sunlight. But as strong ultra violet deteriorates the properties of ABS, customers need to avoid direct exposure to sunlight as much as possible.
7) Recycle is possible
starex Extrusion ABS is thermally so stable that customers can use recycled resin within 30% by weight per virgin starex ABS without significant mechanical properties drop. However, as the number of recycling increases, surface defects such as decoloring might occur.
Properties
1) Mechanical Properties of starex ABS Sheet
The grades of starex Extrusion are suitable for structural materials because of high impact strength and sheet rigidity there of.
2) Impact Strength-Flexural Modulus Balance
The impact and flexural strength balance is the first check point for structural materials. The starex Extrusion ABS grades have excellent flexural and impact strength which compliment both rigid and tough materials.
3) Temperature Dependence of Mechanical Strength
There are two types of product defects: cracks and deformation, which often occur during the manufacturing process as well as in the reliability test. The mechanical strength characteristics of the starex Extrusion ABS at various temperature ranges are displayed in the forming process and reliability test. Tthe starex Extrusion ABS grades keep a stable impact strength of 10kgcm/cm even at a temperature of -30กษ. With its excellent mechanical strength at various temperatures, the resin's stability is revealed.
4) Recycling Characteristics
Due to the thermal stability of starex Extrusion ABS, their properties are well sustained after recycling. However, as the number of recycling increases, surface defects such as decoloring might occur.
