    • A method for producing a terminal bonding tape includes providing a multi-layer film having a linear polyethylene surface layer, a linear polyethylene intermediate layer and an acid-modified polyethylene surface layer, and irradiating the multi-layer film with a radiation beam from the side of the linear polyethylene surface layer to cross-link the linear polyethylene intermediate layer. The linear polyethylene surface layer is made of a high-fluidity linear low-density polyethylene having an MFR of 5 to 30 g/10 min or a linear polyethylene with a density of 918 to 940 kg/m3, while the linear polyethylene intermediate layer is made of a low-fluidity linear low-density polyethylene having an MFR of 0.7 to 6 g/10 min or a linear polyethylene with a density of 865 to 917 kg/m3. The radiation cross-linked intermediate layer shows significant reduction in fluidity with the fluidity of the both surface layers being maintained in an acceptable level.

    • A seamless endless belt formed of a polyether-ether-ketone resin subjected to a specific simultaneous inflation-and-biaxially stretching treatment followed by an optional specific thermosetting/relaxation treatment as well as a process for manufacturing same is disclosed. This belt is manufactured by biaxially stretching a tube of a polyether-ether-ketone resin while inflating the tube at a temperature above the glass transition temperature of the resin but below the melting point of the resin, optionally and preferably thermosetting the stretched tube at 150.degree.-320.degree.C. while relaxing it at a rate of relaxation of 5-30% and then cutting the resultant tube in round slices. The stretched tube may be laminated with a tube of a thermoplastic polyurethane resin so as to form a laminate tube formed of a polyether-ether-ketone resin in the outer and inner tubes with, interposed therebetween, an intermediate tube of a thermoplastic polyurethane resin. A seamless endless tube is manufactured also from the laminate tube in such manner that the laminate tube is heated above the melting point of the polyurethane resin whereby the outer and inner tubes of the polyether-ether-ketone resin are thermoset while being relaxed and the intermediate tube of the polyurethane is melted and integrally bonded to the outer and inner tubes to form an integrally bonded laminate tube which is cut to form a seamless endless belt. The belt thus obtained is excellent in heat-resistance, dimensional stability at a high temperature and mechanical strength and can be used as a conveyer belt or the like especially in electronic apparatus where the belt moves smoothly without any elongation or contraction, even in severe service.
    • 公开了一种由具有特定的同时进行充气和双轴拉伸处理,然后进行特定的热固化/松弛处理的聚醚醚酮树脂形成的无缝环带以及其制造方法。 该带通过在高于树脂的玻璃化转变温度但低于树脂的熔点的温度下对管进行双轴拉伸来制造,任选地且优选地将拉伸管的热固化为150 摄氏320度。 同时以5-30%的放松率放松,然后将成品管切成圆片。 拉伸管可以与热塑性聚氨酯树脂管层压,以在外管和内管中形成由聚醚 - 醚 - 酮树脂形成的层压管,其间插入热塑性聚氨酯树脂的中间管。 也可以从层叠管制造无缝环管,使得将层压管加热到聚氨酯树脂的熔点以上,由此聚醚醚酮树脂的外管和内管在松弛的同时被热固化,中间体 将聚氨酯的管熔化并整体地结合到外管和内管,以形成整体结合的层压管,其被切割以形成无缝环形带。 由此获得的带材具有优异的耐热性,高温下的尺寸稳定性和机械强度,并且可以用作输送带等,特别是在皮带平稳移动而没有任何伸长或收缩的电子设备中,即使在严格的服务 。
