可采用一系列地传统加工技术对K-树脂进行开发应用。纯的K-树脂或者掺混了通用性聚苯乙烯的K-树脂可通过挤出成型制成片材,并且在普通的设备上高产量的进行热成型。除了能高速生产之外,从经济上看,K-树脂能为人所接受,可用于制成不容易破碎的透明饮料杯,盖子和其他包装材料。同样,K-树脂作为注塑成型的加工性能好,循环时间合理,设计灵活。注塑成型的透明的长命合页式盒子利用K-树脂特性的一个例子。K-树脂通过狭窄的合页铰链膜腔注入后,仍具有充分的韧性以确保铰链的寿命。对于中空吹塑成型来说,K-树脂可在大部分的传统设备上加工,而不必对设备做昂贵的改动,例如不需要采用特殊的模具,不同的螺钉或加设干燥便能模塑成型结晶透明的瓶。K-树脂可采用中空吹塑成型制成的各种尺寸和形状的产品,从小药丸瓶,医用引流装置,到高身的陈列展示美工。不必改动注塑吹塑成型设备,也可制成高抗衡强度的玻璃样透明瓶。K-树脂也可制造有刚性的、高光泽的透明标签包装用膜。如果能避免极端的加工和粉碎回收利用,聚合物可反覆多次回收利用,在性能上和加工能上仅有极微小的变化。
与其它透明聚合物想比较,K-树脂共聚物的特点是密度低,从经济角度上看更有吸引力。K-树脂的得率比非苯乙烯类的透明树脂高20~30%,并且符合美国食品药品管理员FDA21CFR1771640条*和欧洲EEC指引90/128/EEC之修订条*的规定,用作食品的包装。K-树脂在医用市场中也占有很大的比例,适合当作USPV1-50材料使用,可以采用环氧乙烷气体或紫外射线消毒。
世界上丁苯透明抗冲树脂(菲利普斯产品名为K树脂)的总产量为150kt,1999年世界需求量估计为240kt。
A series of traditional processing techniques can be used todevelop and apply k-resin. Pure K-resin or K-resin mixed withgeneral purpose polystyrene can be extruded into sheets andthermoformed in high yield on conventional equipment. In additionto high-speed production, k-resin is economically acceptable andcan be used to make transparent beverage cups, lids and otherpackaging materials that are not easily broken. Similarly, k-resinas an injection molding processing performance is good, reasonablecycle time, flexible design. An example of an injection-moldedtransparent long-life hinge box utilizing K-resin properties.K-resin injected through the narrow hinge membrane cavity, stillhas sufficient toughness to ensure the hinge life. For hollow blowmolding, k-resin can be processed on most conventional equipmentwithout costly modifications such as special molds, differentscrews or added drying can be molded into crystal clear bottles.K-resin can be made of hollow blow molding products of varioussizes and shapes, from small pill bottles, medical drainagedevices, to high-body display art. It is not necessary to changethe injection molding equipment, but also can be made into ahigh-strength glass-like transparent bottle. In addition, k-resincan also be made with a rigid, high-gloss transparent labelpackaging film. If extreme processing and crushing recycling can beavoided, the polymer can be recycled repeatedly, with only minimalchanges in performance and processing energy.
Compared with other transparent polymers, k-resin copolymers arecharacterized by low density and are economically more attractive.The yield of K-resin is 20-30% higher than that of non-styrenetransparent resin, and it is in accordance with the regulation ofFDA21 CFR 1771640 * of US Food and Drug Administration and theregulation of European EEC Guideline 90/128/EEC, used as a packingfor food. K-resins also have a large share of the medical marketand are suitable for use as USPV1-50 materials, which can besterilized by oxirane gas or ultraviolet radiation. The total worldoutput of styrene-butadiene clear impact resin (Phillips productknown as K resin) is 150 kt and world demand was estimated at 240kt in 1999.
