K-ResinSBC(K树脂)KR03

K-ResinSBC(K树脂)KR03

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。

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 Resin, alsoknown as K Resin, is a styrene-butadiene copolymer SB, with goodtransparency, gloss, and impact resistance, and prices between PSand PC, so it is widely used in the manufacture of non-fragiletransparent products, such as: Cups, lids, bottles, hinged boxes,hangers, food and medical packaging supplies and so on. Soft K glueis an amorphous polymer, good fluidity, and processing out of theproducts, smooth appearance, gloss, high transparency. Suitable forinjection molding, blow molding, extrusion and other processingmethods, can be in most ordinary equipment processing, do not needto change the equipment and mold. Soft K adhesive features hightransparency, high gloss, high impact resistance, good foldingresistance, non-toxic, low density; easily modified by blendingwith other polymers, such as GPPS, San, PP; easy to process, easyto stain, easy to print. K Glue hardness of each manufacturer isdifferent, to KR03, for example, its hardness is 65 degrees shaw. KAdhesive Chemical Resistance is poor, organic compounds, such asalcohol, ketone, Ester, and aromatic compounds will make k materialsoftening or even dissolved. It is an amorphous polymer thatinterferes less with light than a dense crystalline polymer. As Kadhesive is an amorphous polymer, its melting point is not obvious,the thermal deformation temperature is 77 °C, when the temperatureis higher than 177 °c, the fluidity of the polymer increases, butabove 260 °C, its fluidity begins to be unstable, the polymer willdegrade, resulting in poor appearance and performance of products,such as transparency, color, brittle, and so on.
