韩国大林 KR01 KR03 KR03NW KR05KR10 KK38 K树脂(K-RESIN)SBC苯乙烯-丁二烯共聚物K塑料产品用途及相关性能分析
KR01大部分都用于注塑。相比KR03强度差,但在抗弯性、韧性及表面硬度方面却更加,比透明聚苯乙烯(GPPS)具有更高的耐冲击性。
KR03、KR05、KR10系列从化学方面来讲是同样的产品。
这种等级是根据树脂内胶粒/鱼眼(gel.fish eye)数的多少来分类的。
- KR03用于Zui终成形品中无法用肉眼识别胶粒(gel)的注塑和板挤出成形;
- KR05用于吹塑成型、高品质板挤出、异型挤出(pro-fileextrusion)、射吹成形;
K-ResinK-树脂较其它透明塑料更加具有经济性是因为其密度小
K-ResinK-树脂具有比非苯乙烯系列的透明树脂高20~30%的收益率。
K-ResinK-树脂满足FDA(美国食品药品管理局)于CFR 21条177.1640规定的有关与食品接触的要求事项,还符合90/128/EEC的法令及其修改条款。
软k胶是什么塑料
软K胶由苯乙烯与丁二烯共聚而成,聚苯乙烯具有高透明度,良好的加工性能,缺点是质脆,而丁二烯可聚合成橡胶,具有弹性耐冲击,二者共聚,改善了聚苯乙烯的缺点,得到综合性能良好的聚合物。
K胶又称K树脂,是苯乙烯—丁二烯共聚物(SB),具有良好的透明性、光泽性、和耐冲击性,且价格介于PS与PC之间,因此,广泛用于制造不易破碎的透明产品,如:杯子、盖子、瓶、合页式盒子、衣架、食品和医药用的包装用品等等。
软K胶是无定形聚合物,流动性较好,且加工出来的制品,外观平滑、光泽、透明度高。适用于注塑、中空吹塑、挤出等加工方法,可以在大部分普通设备上加工,不需改动设备和模具。
Soft Kadhesive features high transparency, high gloss, high impactresistance, good folding resistance, non-toxic, low density; easilymodified by blending with other polymers, such as GPPS, San, PP;easy to process, easy to stain, easy to print. K Glue hardness ofeach manufacturer is different, to KR03, for example, its hardnessis 65 degrees shaw. K Adhesive Chemical Resistance is poor, organiccompounds, such as alcohol, Ketone, Ester, and aromatic compoundswill make k material softening or even dissolved. It is anamorphous polymer that interferes less with light than a densecrystalline polymer. As K adhesive is an amorphous polymer, itsmelting point is not obvious, the thermal deformation temperatureis 77 °C, when the temperature is higher than 177 °c, the fluidityof the polymer increases, but above 260 °C, its fluidity begins tobe unstable, the polymer will degrade, resulting in poor appearanceand performance of products, such as transparency, color, brittle,and so on.
