[0009] Non-lead-based stabilizers are not as effective as lead and lead compound-based stabilizers, but non-lead-based stabilizers such as barium-zinc-based, calcium hydroxide-based, calcium-zinc-based, hydrotalcite-based, and octanoic acid metal salts are used appropriately depending on the application. Lead-based stabilizer (for example, refer to Patent Documents 2 and 3)

Abstract

The invention provides a vinyl chloride resin composition, an insulation cable and a cable which adopt the same. The vinyl chloride resin composition can resist and repel epoxy resin during a processof coating the epoxy resin in order to solidify and seal. The insulation cable (10) has an insulation layer containing the vinyl chloride resin composition is arranged on the outer circumference of asemiconductor (1). The vinyl chloride resin composition is formed by a plasticizer and part of ester compounds containing carboxylic acid condensation compound in a basic polymer containing the vinylchloride resin.

Description

technical field [0001] The present invention relates to vinyl chloride resin compositions and insulated wires and cables, and more particularly to flame-retardant vinyl chloride resin compositions and insulated wires and cables applicable to electric wires conforming to UL standards (commonly referred to as "UL wires"). Background technique [0002] Insulated wires used for internal wiring of electronic devices are required to have flame retardancy in order to prevent flames from spreading along the wires in the event of a device fire accident or the like. [0003] Standards of flame retardancy of internal wiring materials are specified in, for example, the UL758 standard in the United States. Among the items required by UL758, there is a vertical burning test (hereinafter referred to as "VW-1 test") as an option, but almost all insulated wires are certified by UL after passing this test, so although it is an option, But the VW-1 test is close to a must-have item. [0004]...
